Its fruit peel can be used as a seasoning and to extract aromatic oil, and can also be used as medicine with effects such as warming the middle and promoting qi flow, expelling cold and relieving pain, and killing insects. The seeds can be eaten and can also be processed into soap

How much is a jin of Sichuan peppercorn seeds?

The price of Sichuan peppercorn seeds is about 4 to 6 yuan per jin, but prices vary depending on seed quality, variety, place of origin, market, and so on. Sichuan peppercorn is suitable for warm and humid conditions and deep, fertile loam and sandy loam. It has strong sprouting ability, is cold-resistant and drought-resistant, loves sunlight, has strong disease resistance, and its dormant buds have a long lifespan, but it is not tolerant of waterlogging. Propagation methods include sowing, grafting, layering, and cuttings, but seed propagation is mostly used in production, because seed propagation of Sichuan peppercorn is simple and easy, with a high propagation coefficient and suitable for large-scale production needs.

What varieties of Sichuan peppercorn are there?

1. Dahongpao: Dahongpao is also known as Shizitou, Dahongjiao, Gedajiao, Qinjiao, Fengjiao, etc. It is an excellent Sichuan peppercorn variety with a wide distribution range and the largest cultivation area in China. It is now cultivated in a concentrated and large-scale manner in Wudu District, Longnan, Gansu, and other places.

2. Dahongjiao: Dahongjiao is also known as Youjiao, Erhongpao, Erxingzi, etc. The tree vigor is moderately strong and the tree posture is open. It is cultivated in various places in the northwest and north China, but cultivation is most concentrated in Hanyuan, Luding, Xichang, and other places in Sichuan.

3. Xiaohongjiao: Xiaohongjiao is also known as Xiaohongbao, Mijiao, Xiaojiaozi, Maweijiao, etc. The tree vigor is moderate, the tree posture is open, the branching angle is large, and the crown is oblate. After drying, the fruit peel is bright red, with a rich numbing aroma, especially a strong fragrance and excellent quality.

4. Baishajiao: Baishajiao is also known as Bailijiao, Baishadan, etc. The tree vigor is moderate, the tree posture is relatively open, and both productivity and yield stability are strong, but the color of the processed peel is relatively poor, market sales are not very good, and it is not suitable for large-scale cultivation. It is relatively common in Shandong, Hebei, Henan, and Shanxi.

Sowing methods for Sichuan peppercorn

1. Seed harvesting: Seed trees for Sichuan peppercorn should be selected from middle-aged trees with strong vigor, heavy fruiting, and excellent quality. When harvesting, choose Sichuan peppercorn that is fully mature, with purple-red fruit peel, blue-black seed surface, plump, and free of pests and diseases for seed use.

2. Seed treatment: First select out shriveled seeds from Sichuan peppercorn seeds with clean water, then soak them for 2 days in a 1% alkaline water solution prepared with warm water, repeatedly rubbing and washing the oil on the seed coat until the seed surface turns grayish white. After removing, rinse clean with clean water, mix with plant ash, and sow.

3. Seedbed selection: The seedbed for Sichuan peppercorn is best a sandy soil that is sheltered from the wind and facing the sun, with fertile soil and good drainage. Combined with land preparation, apply 4000 to 5000 kg of decomposed organic fertilizer, 8 to 10 kg of urea, 30 to 40 kg of superphosphate, and 50 kg of plant ash per mu, then make beds.

4. Sowing time: The sowing time for Sichuan peppercorn should be before the soil freezes, generally from mid-October to early November. In Sichuan peppercorn production areas, sowing can be done immediately after seed collection from mid-to-late August to early September.

5. Sowing method: When sowing Sichuan peppercorn, open furrows in the seedling bed, flatten the bottom of the furrows, evenly scatter the seeds into the furrows, and cover with soil above the furrows. After spring begins, when a small number of seeds break through the soil, scrape off the upper covering soil. When more than 80% of the seeds have cracked open, scrape off the soil again. The sowing rate is 5 to 6 kg per mu.

6. Seedling management: After sowing Sichuan peppercorn, plastic film or wheat straw can be used for mulching. During drought, water can be sprayed, but flooding irrigation should not be used. Keep the seedbed soil moist at all times. When the seedlings grow to 3 to 4 cm tall with 3 to 4 true leaves, thin them. When the seedlings reach 10 cm tall, final thinning should be done.

Planting methods for Sichuan peppercorn

1. Garden site selection: Sichuan peppercorn plants are relatively small, with shallow root distribution and strong adaptability. They can be planted on idle land such as barren hills, wasteland, roadsides, field edges, and in front of and behind houses. They are not suitable for planting on mountaintops, low-lying areas, wind gaps, places with thin soil, exposed rock, or heavy clay.

2. Land preparation and fertilization: Before transplanting Sichuan peppercorn, land preparation is needed, and sufficient base fertilizer should be applied at 4 to 5 tons per mu. When backfilling, about 20 to 25 kg of organic fertilizer should also be mixed in. When preparing land in hilly and mountainous areas, soil and water conservation work must be consistently carried out.

3. Planting density: Sichuan peppercorn should be planted sparsely rather than densely. In arid and semi-arid areas, the density after maturity should be within the range of 100 to 120 plants per mu. In areas with deep soil, good soil quality, and moderate rainfall, the mature density is about 60 plants per mu.

4. Timely planting: Planting at the right time is key to whether Sichuan peppercorn survives. The survival rate is highest when planting is done when the buds just begin to sprout. After planting, water thoroughly, apply topdressing 2 to 3 times during the growing season, and combine with watering during drought.

5. Fertilization management

① Expanding hole fertilization: After the soil thaws in early spring, deeply dig the soil around the root system of the Sichuan peppercorn tree to 30 to 50 cm, and apply about 30 kg of organic fertilizer per plant. In the sprouting period in mid-April and after fruit harvesting in late July, apply 0.4 kg of standard chemical fertilizer per plant each time. After fertilization, water thoroughly in time.

② Foliar spraying: Use a mixed solution of 3% monopotassium phosphate and 0.5% urea for foliar spraying 6 times per year. Spray the first time at the flowering stage, the second time 10 days after flowering, and the third time after another 10 days. Spray once in early-to-mid July and once after fruit harvesting.

6. Pruning and rejuvenation: Prune Sichuan peppercorn in summer in combination with harvesting. For weakened trees, cut off some large branches and diseased and insect-damaged branches, and finally retain 5 to 7 main branches per plant. At the same time, appropriately thin out dense branches within the crown. For moderate-vigor trees, mainly thin out medium and short branches.

7. Timely harvesting: The fruit maturity period of Sichuan peppercorn is generally around the Beginning of Autumn to the End of Heat. When mature, the fruit peel is purple-red or light red, the suture line of the peel protrudes, a small amount cracks open, the seeds are black and shiny, and a rich numbing aroma can be smelled. This is the most suitable harvesting period.

① Picking from strong branches: In the first leaf axil below the large pepper cluster there is a plump bud. This bud is the fruiting bud for the next year and should be properly protected. When picking the pepper cluster, be sure not to remove this axillary bud along with it, so as not to affect next year's yield.

② Picking from weak branches: The first bud below the fruit cluster on a weak branch develops poorly, while the second or third bud develops more robustly. When picking, the second or third bud should be retained; otherwise, next year's yield will be affected.

I. Harvesting Sichuan peppercorn seeds

The harvest season for Sichuan peppercorn is generally August to September, which is also a great time for raising seedlings and collecting seeds. At present, the main promoted varieties are mainly Dahongpao (Shizitou), Xiaohongbao, Huangjinjiao, Youjiao, etc. Seed trees should be selected from middle-aged trees with strong vigor, heavy fruiting, and excellent quality. When harvesting, choose Sichuan peppercorn that is fully mature, with purple-red fruit peel, blue-black seed surface, plump, and free of pests and diseases for seed use.

II. Treatment of Sichuan peppercorn seeds

For newly collected Sichuan peppercorn seeds, first select out shriveled seeds with clean water, then soak them for 2 days in warm water prepared as a 1% alkaline solution or 1% washing powder solution (the amount of water should preferably submerge the seeds), repeatedly rubbing and washing the oil on the seed coat until the seed surface turns grayish white. After removing, rinse the alkaline liquid off the seed coat with clean water, mix with plant ash, and sow.

III. Selection of seedbed for Sichuan peppercorn

Sichuan peppercorn requires sufficient sunlight from the seedling stage onward. The seedbed land should be selected as sandy soil that is sheltered from the wind, facing the sun, with deep and fertile soil, and good drainage. Before sowing, finely prepare the land and break up clods so that the topsoil is loose and the subsoil is firm. Combined with deep plowing and land preparation, apply 4000-**** kg of decomposed organic fertilizer, 8-10 kg of urea, 30-40 kg of superphosphate, and 50 kg of plant ash or 10-15 kg of potassium sulfate per mu. On the basis of fine land preparation, make beds 1-1.2 m wide and 6-10 m long.

IV. Sowing Sichuan peppercorn seeds

Open furrows in the prepared seedling bed with a spacing of 20-25 cm, a depth of 4-5 cm, and a width of 8-9 cm. Flatten the bottom of the furrows, evenly scatter the seeds into the furrows, and cover with soil above the furrows. After spring begins the next year, check the germination situation. When a small number of seeds break through the soil, scrape off the upper covering soil and leave 3-4 cm of soil below. When more than 80% of the seeds have cracked open, scrape off the soil again and leave 1-2 cm. The sowing rate is 5-6 kg per mu. The sowing period should be before the soil freezes, generally from mid-October to early November. In Sichuan peppercorn production areas, sowing can be done immediately after seed collection from mid-to-late August to early September.

V. Seedling management of Sichuan peppercorn

For autumn seedling raising of Sichuan peppercorn, the seeds take a long time to emerge, but the seedlings emerge earlier than with spring sowing. Therefore, in arid areas or places where the seedbed soil is sticky and heavy, plastic film or wheat straw mulching can be used after sowing. During drought, water can be sprayed, but flooding irrigation should not be used. Keep the seedbed soil moist at all times. When the seedlings grow to 3-4 cm tall and have 3-4 true leaves, thin them. When the seedlings reach 10 cm tall, final thinning should be done, with a seedling spacing of about 5 cm, leaving 20,000-30,000 plants per mu. At the same time, irrigate and drain waterlogging in time and apply topdressing, and do a good job of intertillage and loosening the soil, improving soil permeability, clearing weeds in the seedbed, and preventing and controlling pests and diseases, so as to ensure the healthy growth of Sichuan peppercorn seedlings.

[Editor's concluding remarks]Doing a good job in planting Sichuan peppercorn seeds is the foundation for successfully growing Sichuan peppercorn, and attention should be paid to it. The above has introduced the planting methods for Sichuan peppercorn seeds to everyone, hoping it can help everyone!

How much is a jin of Sichuan peppercorn seeds

Sichuan peppercorn is very common in the Sichuan area. Sichuan cuisine is famous for being numbing and spicy, and chili peppers and Sichuan peppercorn are the main seasonings. Sichuan peppercorn is divided into peppercorn hulls and peppercorn seeds. The hulls are used for cooking, and the seeds are used for pressing oil. Peppercorn seeds are heavier than peppercorn hulls. Sichuan peppercorn seeds are actually peppercorn seeds, and the quality of the peppercorn seeds determines the quality of the Sichuan peppercorn. Below let us understand the price of Sichuan peppercorn seeds.

How much is a jin of Sichuan peppercorn seeds

There are many varieties of Sichuan peppercorn seeds, and different varieties have different prices. Prices range from more than ten yuan to more than thirty yuan. The specific price should be inquired about locally.

Storage and germination acceleration of Sichuan peppercorn seeds

The seed shell of Sichuan peppercorn is hard and oily, not easy to absorb water, and relatively difficult to germinate, so degreasing treatment must be carried out. If it is autumn sowing, the seeds can be placed in alkaline water (25 g of alkaline powder for 1 kg of seeds, with water added to submerge the seeds), soaked for 2 days, and the oil on the seed coat rubbed and washed off. After removing, they can be sown. If it is spring sowing, they need to be stored properly to prevent the oil from volatilizing over winter and reducing germination ability. Storage methods vary from place to place, mainly including the following:

1. Plant ash storage: In autumn, use 3—5 times the amount of plant ash as the seeds, add water, stir evenly, and store, keeping it moist frequently.

2. Mud cake storage: Mix the seeds with sandy loam, add water and mix into a thick mud form (or mix in some cow dung), make mud cakes, dry them in the shade, and place them in a dry and ventilated place for sowing the next spring.

3. Jar and pot storage: Pour freshly dried seeds into a jar, cover it, and place it in a cool and dry room. This can also maintain germination ability.

Generally 15—20 days before sowing, remove impurities from the stored seeds and place them in a sunny place in a pile 30 cm high, sprinkle water and cover with plastic film, turn them over once every 1—2 days, and sow when most of the seeds begin to sprout.

Sichuan peppercorn planting methods

1. Seed treatment

Seed treatment: The seed shell of Sichuan peppercorn is hard, oily, impervious to water, and relatively difficult to germinate. Before sowing, degreasing treatment and storage must first be carried out. For autumn sowing, soak the seeds in alkaline water. Use 0.025 kg of alkaline powder for 1 kg of seeds, add water to the extent that the seeds are submerged, remove empty and shriveled seeds, soak for 2 days, rub and wash off the oil on the seed coat, remove them, rinse with clean water, and sow.

For spring sowing, several methods can be used to treat the seeds, such as stratified sand storage, cow dung seed mixing, horse dung mixed piling, or small pit storage. Stratified sand storage is the conventional treatment method; cow dung seed mixing means mixing 6 parts fresh cow dung with 1 part Sichuan peppercorn seeds evenly, burying them in a pit 30 cm deep for winter storage, taking them out before sowing the next spring, breaking them up, and sowing together with the cow dung;

For horse dung mixed piling, from mid-March to mid-April, mix water-selected Sichuan peppercorn seeds with 3 parts horse dung, place them in the sun in a pile, turn them, and sow after they sprout; small pit storage means digging a pit, filling it with water, and storing over winter.

2. Sowing

Sowing is divided into spring sowing and autumn sowing. In spring-drought areas, sowing before the soil freezes in autumn is better, with uniform emergence and emergence 10 to 15 days earlier than spring sowing; spring sowing time is generally around the "Spring Equinox". Sow 25 kg per mu. For small-bed seedling raising, drilling in furrows can be used, with 4 rows per bed, row spacing 20 cm, furrow depth 5 cm, covering soil 1 cm, and sowing 4 to 6 kg per mu. After sowing, cover the bed surface with grass to retain moisture, and remove it in stages after emergence. The method of building ridges can also be used for seedling raising. For autumn sowing, open a furrow 1 cm deep and 9 cm wide every 24 to 27 cm, evenly scatter the seeds into the furrow, and after sowing, cultivate soil from both sides onto the furrow.

After spring begins, check the seed germination situation in time. If a few seeds have cracked, scrape off part of the covering soil and retain 2 to 3 cm. After 5 to 7 days, when most of the seeds have cracked, scrape off part of the covering soil again and keep the covering soil about 1 cm thick, so that the seedlings will soon emerge completely. If spring sowing uses seeds that have been germinated, the seedlings can emerge 4 to 5 days after sowing and emerge completely in about 10 days. This method is suitable for areas prone to spring drought.

3. Seedling management

When the seedlings are 4 to 5 cm tall, thin and final-thin them, maintaining a seedling spacing of 10 to 15 cm. During the seedling growth period, apply 3000 to 4500 kg of human manure and urine per mu in June to July, respectively, or 10 to 25 kg of chemical fertilizer. Fertilization should be combined with irrigation, and intertillage and weeding should be carried out promptly after application. Sichuan peppercorn seedlings are most afraid of waterlogging. When the rainy season comes, the nursery should do a good job of waterlogging prevention and drainage. One-year-old seedlings 70 to 100 cm tall can be taken out of the nursery for afforestation.

Harvesting Sichuan peppercorn

The price of Sichuan peppercorn seeds is not high, and the price of peppercorn hulls is higher than that of peppercorn seeds. The method for germinating Sichuan peppercorn seeds is very simple. They can be soaked in alkaline water for 2 days, the oil washed off, and then sown after removal. There are two sowing stages, spring and autumn. Planting Sichuan peppercorn is relatively easy, and management is also simple. Harvesting Sichuan peppercorn requires the most manpower, because Sichuan peppercorn can only be harvested by hand, and the Sichuan peppercorn tree also has thorns.
