With the continuous expansion of the medical care scope of Astragalus membranaceus the increasing demand for Astragalus membranaceus, the development of Astragalus production has a better market prospect. Let's take a look at the planting conditions planting benefits of Astragalus membranaceus.

1. Planting conditions of Astragalus membranaceus

(1) Astragalus membranaceus prefers cool, cold drought tolerance, is afraid of heat waterlogging. It is suitable for planting in sandy loam soil with deep soil layer, rich humus strong water permeability, but in saline alkali soil. In the year of direct seeding, it only grows stems leaves without flowering, but can blossom bear seeds in the second year.

(2) the root of remembranous milk vetch is a deep root crops, should choose soil deep, loose soil, rich, good drainage, xiangyang high dry, neutral slightly acidic sandy loam, soil heavy root with slow growth abnormalities, thin soil, root, more branches, more show "chicken claw", quality is poor, the ground sunny slopes are planting, preceding with gramineous crop advisable, avoid is continuous cropping, unfavorable potato, til rotation.

II. Planting time of Astragalus membranaceus

1. Seed treatment: Astragalus seeds have the characteristics of hard seed, which must be treated before sowing. The methods are as follows.

(1) Sulfuric acid treatment: the germination rate of old hard Astragalus membranaceus seeds is more than 90% with concentrated sulfuric acid, which is about 50% higher than that without treatment. The seeds are processed for 2 minutes at a temperature of 30℃, then the seeds are rinsed with water.

② Mechanical treatment: sanding soaking in warm soup can both improve the germination rate of astragalus hard seeds, soaking in warm soup combined with sanding is more feasible in production.

2. The sowing time: astragalus can be sown in the spring, summer, autumn three season, spring, after the "tomb-sweeping day" holiday no later than the latest "gu yu", keep the soil moist, about 15 days to emergence, summer sowing in June to July, 7 ~ 8 days after sowing can emergence, autumn sowing in "the millennium", before after low temperature treatment, new seeds to prevent frostbite in winter.

3. Planting methods: astragalus membranaceus USES drilling normally, about 20 centimeters apart, channel 3 cm deep, mu with a rate of 2 ~ 2.5 kg, sowing seeds, the seed with pesticide methamidophos strain seed underground pest prevention, cover soil after seeding, mu shi diamine 8 ~ 10 kg phosphate, potassium sulfate fertilizers 5 ~ 7 kg, sowing to seedling stage to keep the ground moist add mulch to promote emergence, can also be dibbling seeding.

Third, the planting benefits of astragalus

1. Cost input

(1) Seed cost: Generally, about 2.5 kilograms of seeds are needed for each mu of land. The seed price is 100 yuan/kg, 250 yuan is needed.

(2) Land rent: 600 yuan per mu.

(3) Fertilizer costs: generally each mu of land needs to decomposed farmhouse fertilizer 2500 ~ 3000 kg, NPK compound fertilizer 50 kg, each mu needs about 400 yuan.

(4) Labor cost: the cost of watering, planting, mining management shall be calculated at 500 yuan per mu. The total cost per mu is about 1750 yuan.

2. Revenue analysis

The per-mu dry product yield of Astragalus is 350 ~ 400 kg. At present, the market price of Astragalus is 18 ~ 23 yuan/kg, the income per mu can reach 6300 ~ 9200 yuan. Apart the cost, the net income per mu is 4550 ~ 7450 yuan, the economic benefit is very considerable. The benefit would be even higher if the growers kept their own crops.
