How much do Agrimonia pilosa seeds cost? Detailed planting methods
Agrimonia pilosa, also known as laohe zui, maojiao yin, longya cao and so on, is a perennial herbaceous plant of the genus Agrimonia in the Rosaceae family. Its tender stems and leaves are edible, and it is not only rich in nutrients but also has strong anti-cancer effects. The whole plant, roots and winter buds are used as medicine and have effects such as astringing and stopping bleeding, reducing inflammation and stopping dysentery, detoxifying and killing insects, and boosting qi and strengthening the heart. Let us take a look at the price of Agrimonia pilosa seeds and its planting methods!
How much is a jin of Agrimonia pilosa seeds?
The price of Agrimonia pilosa seeds is about 300 to 500 yuan per jin, but prices vary greatly depending on seed quality, variety, place of origin and market. Agrimonia pilosa is produced throughout northern and southern China and can be propagated by seed or by division. When harvesting the above-ground parts, select well-growing fields and leave them as seed fields, apply more fertilizer and strengthen management. After mid-August, when the seeds turn from green to brown and appear slightly dry, cut them off and dry them in the sun, then thresh the seeds and store them in a ventilated, dry place for later use.
Sowing methods for Agrimonia pilosa
Agrimonia pilosa can be sown in spring or autumn. For spring sowing in the north, this is done in mid to late April, and for autumn sowing it is done in late October before the ground freezes. When sowing, open sowing furrows 1 to 2 cm deep at a row spacing of 30 to 35 cm, sow the seeds evenly into the furrows, cover with a thin layer of soil, press lightly, and water promptly after sowing. The seeding rate is 1 to 1.5 kg per mu. When the whole plant is used as medicine, it is harvested in the second year after sowing, while when the root buds are used as medicine, it is harvested in the autumn of the second year.
Planting methods for Agrimonia pilosa
1. Site selection and land preparation: Agrimonia pilosa has no strict requirements for soil, but low-lying fields and plots with poor drainage should not be chosen. After selecting the plot, apply 2000 to 3000 kg of barnyard manure or compost per mu as base fertilizer, spread it evenly and then plow, and make flat beds or raised beds about 1 to 3 m wide.
2. Proper thinning: When the Agrimonia pilosa seedlings are 3 to 5 cm tall, begin thinning and filling in gaps, pulling out the overly dense small and weak seedlings. When the seedlings are 15 cm tall, thin to 1 to 2 plants per spot at a plant spacing of about 15 cm. If the root buds are used as medicine, this can be appropriately increased to 30 cm.
3. Cultivation and weeding: Timely weeding and loosening the soil during the seedling stage of Agrimonia pilosa is the key to ensuring high yield. Usually, hoeing is carried out together with loosening the soil. In the later growth stage, after the plants close the rows, there is no need to loosen the soil again, but any weeds should be pulled out promptly.
4. Timely topdressing: Agrimonia pilosa is fertilized once before and once after final thinning and row closing, and thereafter topdressing is needed again in early spring each year and after each harvest. If the whole plant is used as medicine, more nitrogen fertilizer can be applied, while if the root buds are used as medicine, appropriately more phosphorus and potassium fertilizer should be applied.
5. Removal of flower stems: Agrimonia pilosa grows very vigorously and produces particularly many flowers and seeds. Therefore, except for plants kept for seed, the flower stems should be removed promptly to promote root growth and thereby increase yield.
6. Disease and pest control: The main pest of Agrimonia pilosa is the red spider mite, which pierces and sucks the stems and leaves, causing the leaves to turn yellow, fall off and the plants to die. Propargite, pyridaben and similar agents can be used for spray control.
