Description

Cultivation techniques The cultivation method 1, soil choice: cultivated liquorice should choose 1.50 meters below the underground water level, good drainage condition, soil thickness greater than 2 m, no the harden layer, PH is controlled in 8, irrigation convenient sandy soil is better. Requirements are preferably QiuFan, if too late QiuFan, spring also can, but must ensure that the soil moisture, break KeLa, leveling the ground, otherwise it will affect the full stand strong seedling. 2, seed treatment: before planting the seed in electric rice mill grinding, or place seeds weighing on ceramic tank, press 1 kg seed 30 ml of sulfuric acid and 80% for the seed, stir with smooth stick again and again, after 7 hours at 20 degree centigrade temperatures of stuffy, then wash with water several times, to dry the spare germination rate can reach more than 90%. 3, seeding: liquorice in spring, summer, autumn three seasons can sow, including in summer sowing in May, for the best, when temperature is higher, while the fast, and have longer growth period before winter. Use of high quality 4000 kilograms per mu of farmyard manure before planting, phosphate diammonium 35 kg per mu do basal, if use seed sowing, sowing method can be used drilling or dibbling, 2-2.50 kg per mu of seeding rate, 30-40 cm, spacing planting distance 15 cm, 2.50 3 cm deep, every hole 3-5 grain, turns the soil after seeding BaMo keep moisture.
Field management.
(1) application
(2) water: seeding was water 3 to 4 times, each time the irrigation water is in commonly 85 cubic meters per mu, the first water in about a month after emergence, every 1 months after irrigation, water filling and wintering in mid-october, 2, 3, 4 years to gradually reduce the irrigation frequency.
(3) the thinning out: when the liquorice seedlings grow 15 centimeters high to thinning, planting distance 15 centimeters, about BaoMiao about 20000 plants per mu.
(4) row weeding
(5) seed production
