Planting technology and mu income of licorice

Soil selection: suitable for planting in arid and semi-arid sandy soil. Cultivation method: the method of drill sowing or hole sowing is adopted, the row spacing of sowing is 35cm, and the plant spacing is 20cm. Field management: In the second-third year after planting, phosphorus fertilizer can be topdressed in spring, and intertillage and weeding should be carried out 3-4 times a year. Control of pests and diseases: the use of bordeaux mixture, fenitrothion, dimethoate EC and other chemical control. Planting income: The annual income of one mu of land is about 1000 yuan.

1. Selection of soil

1, licorice likes to grow in arid and semi-arid sand, or desert areas, adaptability is relatively strong, drought resistance, heat resistance, cold resistance, salt and alkali resistance, planting depth should be below 1.5 meters, at the same time to loose soil, good drainage, deep soil layer, perfect soil structure, pH alkaline.

2, turning over the ground is deep turning, usually in the autumn need to turn over the land, at the same time to break the soil, leveling the land, you can wait for planting.

II. Cultivation methods

1, first need to select seeds, and then the licorice seeds, put into the temperature of about 20℃ environment for stuffy seeds, wait about 7 hours to remove, and then rinse with clean water, the water can be dried for sowing, which is conducive to improving the germination rate of seeds, generally can reach more than 90%.

2, licorice planting time is also relatively wide, usually spring, summer, autumn three seasons can be planted, but the better planting time is May, sowing can be used in the way of drilling or hole sowing, sowing row spacing is about 35cm, plant spacing is about 20cm.

III. Field management

1, licorice is a perennial herb, generally in the second to third year after planting, can be applied in the spring phosphorus fertilizer, can be applied in the ditch ring, and in the year after planting, at least 3-4 irrigation is needed. Wait until the late growth period, can gradually reduce the number of watering.

2, when the seedlings grow to about 13cm, it is necessary to carry out reasonable thinning, which is conducive to ensuring the spacing of seedlings in the field. At the same time, at least 3-4 times of intertillage and weeding should be carried out every year.

IV. Prevention and control of diseases and insect pests

1. Common diseases include rust, brown spot and powdery mildew. These diseases are basically caused by fungal infection. Generally, they can be controlled by using Baume sulfur mixture, Bordeaux mixture and Baume sulfur mixture plus rice soup.

2. Common pests of licorice include aphids and red spiders. Aphids and red spiders are common pests in the cultivation of many medicinal materials. Generally, they can be sprayed with fenitrothion or dimethoate emulsifiable concentrate.

V. Income from planting

The annual demand for licorice in China can reach 70,000 tons, and the export volume also continues to grow. The market purchase price of licorice is 7-8 yuan/kg, the retail price is 10 yuan/kg, and the general cost of planting one mu of land is 600 yuan. If the output of one mu of land is 1000 kg in three years, the annual income of one mu of land can reach about 1000 yuan.
