Polygala planting technology and mu income, with planting time

Planting time: spring sowing time is from March to April, autumn sowing time is from mid-October to early November. Land selection and preparation: planted in sandy or semi-sandy soil with high terrain and fertile soil layer. Fertilizing and turning the soil: manure, phosphate fertilizer, potash fertilizer and nitrogen fertilizer can be applied. Seed selection treatment: seed soaking with full grains and disease-free seeds. Sowing: sowing seeds with a special seeder for traditional Chinese medicine. Mu income: 3000-4000 yuan.

First, planting time

Yuanzhi can take direct seeding or seedling transplanting, spring sowing time is from March to April, autumn sowing time is from mid-October to early November, autumn sowing comes out in the spring of the second year, and now agriculture has entered the era of mechanization. therefore, mechanization makes planting and production more convenient, time-saving and labor-saving.

II. Land selection and preparation

Yuanzhi has strong adaptability and is suitable for planting in sandy or semi-sandy soil with high topography, sunny, deep soil layer, fertile and good drainage.

Fertilizing and ploughing the land

Before planting, apply manure 2000-2500kg, phosphate fertilizer 100kg, potassium fertilizer 10kg, appropriate amount of nitrogen fertilizer, spread fertilizer evenly on the ground, and then use large machinery or small tractors to deeply turn the land above 30cm, promote the fertilizer and soil to be fully mixed, and then flatten and rake fine to form a high border with a width of 1.3m. The width of the ditch is 40cm, which requires that the bottom of the ditch be flat and the drainage is relatively smooth.

IV. Seed selection and treatment

Select seeds with full grains and no disease, then sow them with 2 times the volume of wet sand for 12 hours, store them in a cool place, keep suitable humidity, stir once a day, wait for a few days to squeeze out buds with your fingernails before sowing, the emergence rate is high and neat, dry seeds can not be sowed directly, so the germination rate is relatively low.

5. Sowing seeds

The main results are as follows: (1) first, mixing the treated seeds and the heavy stubble of traditional Chinese medicine together before sowing is beneficial to increase the yield, enhance the disease resistance of the seeds, and reduce the incidence of diseases and insect pests. The heavy stubble can be used to increase the dosage according to the serious disease area of continuous cropping, according to the row spacing of 21-24cm and the ditch depth of 1-1.5cm. After sowing the seeds, tread lightly or cover with wheat bran to preserve moisture.

(2) A special seeder for traditional Chinese medicine can be used, and then the row spacing, deep trenching, sowing, soil cover and compaction can be completed in one step, and the amount of seeds per mu is 3-4kg, or you can also use large machinery to sow seeds, adjust the depth, row spacing, generally driven by tractors, more suitable for large-scale planting, watering after sowing, the wet land does not need watering, and seedlings will emerge about 15 days after sowing.

VI. Seedling raising and transplanting

The method of raising seedlings of Polygala tenuifolia is the same as that of direct seeding. The amount of seeds used per mu can be increased appropriately, and the amount of seeds per mu is 10kg. 8-10 mu of land can be transplanted for one year at the end of autumn or in the early spring of the next year.

7. Income per mu

The price of the commodity is determined by quality, the market price is 30-110yuan / kg, the yield per mu is 250-300kg, and the income per mu is 3000-4000 yuan.
