Cultivation Techniques of huang qi tcm

Selection of land preparation

The yellow astragalus encounters water will occur rotten roots and dead seedlings, the plain area cultivation to choose the terrain is high, good drainage, strong percolation of sandy soil planting; high water table, rainfall areas should choose high dry land and highland along the river planting; mountainous areas should choose soil layer deep, fertile soil, soil percolation of strong sunny hillside planting. Yellow Jain for deep-rooted plants, to promote the root development of robust, in the fall requires a deep turn of the land up to 40 cm or more, for a high border, open deep ditch, which is an important measure to prevent yellow Jain rotten root in the plain areas of the high-water table. The border with ditch width of 160 cm, a border made of turtleback shape, and every two borders open a deep ditch, a shallow ditch of 10 cm, deep ditch of 50 cm.

Planting and management

Transplanting can be done in the spring of the second year (with autumn sown seedlings) when the seedlings are 10-15 cm high. The seedlings are placed flat or diagonally in the trench, covered with soil and trampled, and watered thoroughly.
Base fertilizer
The astragali radix root deep, long growth period, to meet its growth and development of nutrient needs, the whole land must be applied to the base fertilizer, per mu of high-quality farm fertilizer 3000-4000 kg plus calcium superphosphate 20-30 kg or diammonium phosphate 8-10 kg, appropriate in the fall before the deep turn into the ground surface, and then turned into the tillage layer, at the latest to be applied before the whole land for the border. Fertilizer should be applied evenly.
Fertilizer should be applied 2 or 3 times according to the climatic conditions and growth potential. The first time is in early May to late May when the seedlings are 10-20 cm high, watering thin manure, 750 kg of human manure and urine, or 1500 kg of pig manure and urine per mu watering; the second time is in early June when the seedlings are 30-40 cm high, 25-30 kg of urea per mu; if the early fertilization, yellow leaves, then in early July to late July when the seedlings are 60-80 cm high, then the third fertilization, when the seedlings are 60-80 cm high. By this time, the monopoly has been closed and nitrogenous chemical fertilizer, cake fertilizer, and calcium superphosphate can be applied.
Seedling emergence, seedling interval, seedling setting, seedling replenishment
Seedling emergence starts 7 days after sowing and seedlings come out in about 30 days. When the seedlings are 5-7 cm high, the first interplanting is carried out. After 2-3 interplanting, one strong seedling is left at 8-10 cm intervals. In the case of missing trees, the seedlings should be replanted with soil, or the seedlings can be replanted with sprouted seeds.
Mid-tillage weeding
If the seedlings are not weeded, they will be weeded promptly. The second time in the seedlings 8-9 cm high, the third time in the seedlings after each weeding 1. In the second year, the weeding is done once in May, June, and September. Keep the field free of weeds regularly.
Watering to prevent flooding
Keep the soil moist before emergence, and water sparingly after emergence to promote the root system to take root. In will bloom when appropriate irrigation, seeds should not be watered or watered after maturity. The yellow sage growth period of June, July, and August coinciding with the rainy season, the field (border) between the occurrence of flooding and water to be promptly excluded, and subsequently for medium plowing, to maintain the field surface soil has good permeability to facilitate the growth of the root system to prevent rotten roots. After autumn, when the upper stems and leaves wither, cultivate the soil to facilitate overwintering.

The region in late October harvest, with tools to carefully dig the whole root, avoid touching the outer skin and broken root, remove the soil, while fresh cut off the reed head, repair the root, sun to half dry, pile 1-2 days, so that the moisture, and then spread out to dry, repeated drying, until the whole dry, the root will be straight, tied into small bundles, can be used for medicine. The quality of thick, wrinkled, yellowish-white, powdered enough, the sweet taste is better. In a normal year, it can produce about 300 kg of dried product per mu.
Seed saving
Select more than 3 years of growth, no disease, and pest plots for the seed field. The harvesting of the seeds of yellow sage is appropriate in September when the fruit pods are pendulous yellow ripe, seeds become brown immediately, otherwise, the fruit pods crack, the seeds are scattered, and difficult to harvest. Because the seed maturity period is not consistent, should be ripe with the harvest. If a small area of seed, it is best to harvest in stages and batches and cut off the mature fruit spikes one by one, discard the immature fruit at the apex of the spike, leaving the lower part of the mature fruit pods. If a large area of seed saving can be harvested at a time when 70-80% of the fruit in the field is mature. After harvesting, first, hang the fruit branch upside down and dry it for a few days to make the seeds ripe, then dry, threshing, Yang clean, and storage.

Mechanical damageThe seeds are quickly crushed several times with a stone mill, so that the outer seed coat changes from a brown-black shiny state to a gray-brown rough skin, to facilitate the seeds to absorb water and swell. Can also mix the seeds into 2 times the fine sand rubbing, rubbing the seed coat, and can be planted with sand.
Acid treatmentFor old and hard seeds, can be 70-80% concentrated sulfuric acid solution soaked for 3-5 minutes, taken out quickly placed in running water, and rinsed half an hour after sowing, this method can destroy the hard seed coat, the germination rate of 90% or more, but should be used with caution.

Sowing method

The sowing time is divided into spring and autumn sowing. Spring sowing is mostly used from late April to early May, with seedlings appearing in early May and taking about one month to grow. When sowing, sow a shallow trench at a 45-60 cm interval on a well-defined border with a width of 8-10 cm. Apply 10 kg of three-element compound fertilizer (15% each of nitrogen, phosphorus, and potassium) as seed fertilizer, cover the soil with 5 cm, step on the bottom grid and then use the strip sowing method, scatter the treated seeds evenly into the ditch, then cover with 1.8-2.4 cm thick soil, step on it once or suppress it once. The amount of seed used per mu is 1.5-2.5 kg.
