What is the latest price of Amomum villosum seeds? With planting methods

Amomum villosum, also known as Yangchunsha, green-shell sand, Hainan sand, etc., is a perennial herbaceous plant of the genus Amomum in the ginger family. It is distributed in Fujian, Guangdong, Guangxi, Yunnan and other places, cultivated or wild in shady and humid mountain areas. Its fruit is used medicinally to resolve dampness and stimulate appetite, warm the spleen and stop diarrhea, regulate qi and prevent miscarriage. Now let us take a look at the price of Amomum villosum seeds and planting methods!

How much is one jin of Amomum villosum seeds?

The price of Amomum villosum seeds is about 60-80 yuan per jin, but prices vary greatly depending on seed quality, variety, place of origin, market, etc. Amomum villosum prefers the warm and humid climate of tropical and south subtropical monsoon forests. It is not cold-tolerant, can withstand brief low temperatures, and dies when frozen at -3°C. It is afraid of drought, avoids waterlogging, and prefers diffused light. It is suitable for cultivation on loam and sandy loam with deep, loose topsoil and strong water and fertilizer retention. In production, seed propagation and division propagation are commonly used.

What types of Amomum villosum are there?

1. Green-shell sand: Green-shell sand is 1-2 m tall, flowers in April-May, and its capsule is spherical or elliptical, slightly triangular, green on the outside with spiny protrusions, and has many seeds. It matures in August-September.

2. Red-shell sand: Red-shell sand differs from green-shell sand in that its leaves are larger, the underside of the leaves is hairy, and the fruit is smaller, round, and red on the outside. Its fruiting rate is relatively high, but the quality is poor, so it is not widely cultivated.

3. Yangchunsha: Yangchunsha differs from green-shell sand in that the outside of the capsule is purple-brown, and the underground stem is more noticeably red than that of green-shell sand. Its quality is good, and it is the main variety traded and circulated on the market.

Sowing methods for Amomum villosum

1. Seed collection: Amomum villosum seeds mature around August-September. Select plump and robust fruits, sun-dry the fruits twice before sowing, then ferment the fruits after sun-drying, maintaining the fermentation temperature (between 30-35°C) and a certain humidity. After 3-4 days, wash and rub off the fruit skin, dry them, and they are ready for sowing.

2. Land preparation and fertilization: Choose a wind-sheltered place with convenient drainage and irrigation for the Amomum villosum nursery. Deep plow and harrow finely to make beds. The bed height is 15 cm and the width is 1-1.2 m. Apply sufficient base fertilizer. Apply 15-25 kg of calcium superphosphate per mu mixed with 1000-1500 kg of organic fertilizer fermented with cow dung or compost.

3. Timely sowing: For Amomum villosum, sow in March in spring and from late August to early September in autumn. Sow in drills or in holes. Before sowing, build a shed frame first. Add coverage for shade when seedlings emerge, with 80-90% shade being suitable. When there are 7-8 leaves, the shade can be appropriately reduced, but the shade degree must not be lower than 70%.

4. Topdressing at seedling stage: For the first topdressing of Amomum villosum at the seedling stage, when there are 2 leaves, use 1.5-2 kg of ammonium sulfate nitrogen fertilizer per mu diluted in 1500 kg of water. When there are 5 leaves, use 3 kg of nitrogen fertilizer per mu diluted in 1500 kg of water. After 10 leaves, apply topdressing once every half month, using 3 kg of nitrogen fertilizer per mu diluted in 1000 kg of water.

5. Seedling management: During the seedling stage of Amomum villosum, water frequently to keep the soil moist. In winter and early spring, apply more decomposed cow dung and plant ash to enhance cold resistance. When a cold wave comes, set up windbreaks on the north side of the beds and use smoke to prevent cold damage. Thin seedlings when they are 10-15 cm tall, and transplant them out of the nursery when they are 50 cm tall.

Planting methods for Amomum villosum

1. Soil selection: For Amomum villosum, it is best to choose fertile, loose sandy loam or light clay loam with strong water and fertilizer retention. Broadleaf evergreen forest land with high humidity and a water source, as well as hillsides, valleys, and flat land with convenient drainage and irrigation, can all be planted. Sandy soil and heavy clay soil are not suitable.

2. Forest land preparation

① Mountain areas: Before planting in mountain areas, clear the land, remove all weeds and cut down excessive shade trees. Areas lacking enough shade trees should be replanted. Dig circular mountain drainage and irrigation ditches to prevent drought and drain waterlogging. At the same time, plant many fruit trees nearby to expand nectar sources and attract more pollinating insects.

② Plains: For planting on plains, dig ditches and make beds. Shape the bed surface into a turtle-back form to prevent water accumulation. Also pay attention to creating shade trees. First plant fast-growing crops such as banana and tephrosia for temporary shade, then plant tall white rice tree, albizia, and fruit trees as permanent shade trees.

3. Field management

① Before reaching the age of flowering and fruiting, a relatively large degree of shade is needed, with 70-80% being suitable. Weed 5-8 times per year, once a month during the rainy season. In addition to applying phosphorus and potassium fertilizer, appropriately increase nitrogen fertilizer. Apply fertilizer 3-4 times per year from February to October, and pay attention to watering to keep the soil moist.

② After entering the age of flowering and fruiting, more sunlight is needed during the flower bud differentiation stage, and maintaining an average shade degree of 50-60% is more suitable. However, in sandy soil with poor water retention or where water sources are lacking, a shade degree of about 70% should be maintained. At the same time, mainly weed twice each year.

4. Pest and disease control

① Stem blight: Stem blight occurs during the rainy season in July-August. After seedlings are damaged, the stems dry up, lodge, and die. For control, spray 1:1:1404160 Bordeaux mixture.

② Leaf spot: Leaf spot occurs at the seedling stage or in the field. For control, remove diseased plants and spray 1:1:120 Bordeaux mixture or 1000-fold amobam aqueous solution.

③ Fruit rot: For control of fruit rot, pay attention to ventilation and light transmission, drain accumulated water. During the young fruit stage, spray 1% formaldehyde solution at 50 kg per mu. After harvesting the fruit, spread 15-20 kg of lime and plant ash at 1:243.

④ Stem borer: Stem borers damage seedlings. For control, strengthen water and fertilizer management. During the peak egg-laying period of adults, spray 40% dimethoate emulsifiable concentrate 1000-fold solution or 90% trichlorfon original powder 800-fold solution.
