1. Growth Habits Sophora flavescens likes warm climate. To soil requirement: With soil layer deep, loose fertile, rich in organic matter sandy loam cultivation is good. Low-lying land, saline-alkali land, difficult to grow.

Second, soil preparation and fertilization select high terrain, good drainage field, deep ploughing and fine cultivation. Combined with soil preparation, apply sufficient base fertilizer: 3000 kg of miscellaneous fertilizer, 20 kg of urea and 50 kg of phosphorus and potassium fertilizer per mu. Then make 1.3 meters wide high bed, waiting for sowing.

3. Sowing Sophora flavescens can be propagated by seeds or by plants. The sowing time is divided into spring sowing and autumn sowing. Spring sowing before and after Qingming, autumn sowing before freezing. Seed propagation: before sowing, the seeds of radix sophora flavescentis are soaked in water at about 50 DEG C for 10-12 hours. Then according to the row spacing 65×50 cm sowing on the whole good ridge surface, watering to preserve moisture, in order to facilitate emergence. Sowing rate 2 kg per mu. Put 3-5 seeds in each hole. Plant division propagation: cut the head of Sophora flavescens into several pieces according to the number of bud eyes; each piece has 2-3 bud eyes, which are used as propagation materials. After the wound heals, plant on the finished bed surface according to the row spacing of 65×50 cm. Water preservation, in order to survive.

IV. Field management: after Sophora flavescens seedlings are complete, pay attention to intertillage and weeding. For large-scale planting, soil treatment with field herbicides before seedling can effectively control various weeds. Dry weather timely watering, rainy weather pay attention to drainage. After budding, except for seed plants, buds should be removed to prevent nutrient consumption. Topdressing once a year before and after the beginning of autumn: urea 10 kg, potassium dihydrogen phosphate 10 kg per mu. Sprinkle a layer of soil manure on the bed surface in winter.

V. Control of diseases and insect pests There are few diseases and insect pests in Sophora flavescens. If they are found, they should be controlled by conventional methods.
