Planting conditions of Radix Astragali

Astragalus membranaceus is a famous traditional Chinese medicine and an important variety of export foreign exchange earnings. there are more than 200 kinds of proprietary Chinese medicines using astragalus as raw materials. With the continuous expansion of the scope of medical and health care of astragalus, the demand for astragalus is increasing. The development of astragalus production has a good market prospect. Let's take a look at the planting conditions and benefits of astragalus.

Planting conditions of Radix Astragali

Astragalus is cool, cold and drought-resistant, and afraid of heat and waterlogging. It is suitable to be planted in sandy soil with deep soil layer, rich in humus and strong water permeability. Strong saline-alkali soil is not suitable for planting. Direct seeding only grows stems and leaves but does not blossom in that year. In the second year, it blossoms and produces seeds. Astragalus membranaceus is suitable for planting in the provinces and regions of Northeast, Northwest and North China.

Astragalus membranaceus is a deep-rooted crop, we should choose neutral or slightly acidic sandy loam with deep soil layer, loose soil, fertile soil, good drainage, sunny and dry sandy loam, soil sticky heavy root growth slow belt deformity, thin soil layer, many horizontal roots, many branches, showing "chicken claw shape", poor quality, flat or sunny hillside can be planted, the previous crop is suitable for Gramineae crops, avoid continuous cropping, not with potato, flax rotation.

Planting time of Radix Astragali

1. Seed treatment: the seeds of Radix Astragali are hard and must be treated before sowing. The methods are as follows.

① sulfuric acid treatment: the germination rate of mature hard astragalus seeds treated with concentrated sulfuric acid was more than 90%, which was about 50% higher than that without treatment. 5 ml / g of 90% sulfuric acid was used. Under the temperature of 30 ℃, the seeds were treated for 2 minutes and then washed clean with clean water.

② mechanical treatment: both sand grinding and warm soup soaking can improve the germination rate of hard seeds of Radix Astragali, and warm soup soaking combined with sand grinding is more feasible in production.

2. Sowing time: Astragalus membranaceus can be sowed in spring, summer and autumn, spring sowing can be carried out before and after the "Qingming Festival", no later than "Grain Rain", keep the soil moist, seedlings can emerge in about 15 days, summer sowing is carried out from June to July, seedlings can emerge 7-8 days after sowing, autumn sowing is generally carried out before and after "White Dew", new seeds are treated at low temperature to prevent frostbite in winter.

3, sowing method: Astragalus usually uses strip sowing, row spacing of about 20 cm, groove depth of 3 cm, sowing amount of 2: 2.5 kg per mu. When sowing, the seeds are mixed with methamidophos or pyrethroid pesticides to control underground pests, and the soil is suppressed after sowing. 8: 10 kg of diamine phosphate per mu, 5 kg of potassium sulfate as base fertilizer, sowing to seedling stage to keep the ground moist or add mulch to promote seedling emergence, or hole sowing and sowing.

Planting benefit of Radix Astragali

1. 5 kilograms of Astragalus seedlings are needed per mu of land. Now the market price of Astragalus seedlings is 100 yuan, 5 kilograms × 100 yuan = 500 yuan.

2. The local area is mainly mountainous, and it costs 100 yuan per mu of ploughed land.

3. Planting one mu of land requires people to plant it for a day, with a salary of 40 yuan per person, and 3 people x 40 yuan = 120 yuan.

4. During the 9-month growth cycle, weeding takes 5 man-hours, each labor expenditure is 40 yuan, 5 people × 40 yuan = 200 yuan.

Chemical fertilizer needs to be fertilized 1 pack per mu, with a cost of 120 yuan per package.

For the autumn harvest in October, 12 people per mu are needed to dig for one day, with a salary of 40 yuan per person, and 12 people × 40 yuan = 480 yuan.

7. The total cost of planting one mu of Radix Astragali is 1520 yuan.

8. Astragalus membranaceus can receive an average of 1500 jin of fresh goods per mu in autumn harvest, and the average price per jin of fresh goods is 3 yuan, 1500 jin × 3 yuan = 4500 yuan.

9. The income minus the cost, the income is 4500 yuan-the planting cost is 1520 yuan, and the income of astragalus is about 2980 yuan per mu.

10, fresh astragalus about 5.5kg dry 1kg, 1500 jin fresh goods dry astragalus about 270kg, according to the market price 20 yuan per kilogram, 270kg dry goods x 20 yuan per kilogram-planting cost 1520 yuan = 3880 yuan
