The cockroach medicine has the same homologous, large market consumption, and has the characteristics of drought resistance, cold tolerance, salt and alkali resistance, wide planting range, long yield after planting, and good development prospects. There are several aspects to be aware of when planting in spring. 1. Choose a good variety and choose a good seedling. If the seedlings are good or bad, look at the variety, look at the root system, and see if it is dry. The main varieties promoted in these years are Ningjing 4, 5, and 6. The common characteristics of these varieties are large fruit, bright color, and high yield; the roots of the seedlings are underdeveloped, especially the roots of the old shoots are poorer. High-quality seedlings should have three vital roots; in addition, the excavated seedlings should not be exposed to the sun, prevent the stems and roots from drying out, reduce the survival rate, and ensure the integrity of the roots. 2. Choose land for planting. Choose sandy loam with loose soil fertility and salinity of not more than 0.3% for planting. If the soil layer is shallow during planting, you can dig a 0.6-1.0 m deep, 0.5-0.8 m diameter planting hole, and apply 0.5 to 1 kg of crops and other straws at the bottom of each hole, covering 0.5 to 1 kg of fully decomposed farmyard manure. Then backfill the cooked soil, then plant the alfalfa, keep the roots of the seedlings stretched, compact the soil, and pour enough water. The planting hole is covered with black mulch, which can maintain the soil moisture, prevent the salt from moving to the surface layer, prevent the weed growth and affect the growth of the cockroach. In areas where underground diseases occur severely, fungicides can be used to prevent root rot. The plant spacing was kept at 1 m 2 . 3. Seedling management. Prevent cattle, sheep and hares from feeding on the stems, and use the flag in the field to disturb the buds. After germination, the buds should be smeared in time, and the buds of the main stalks below 0.6 m should be thoroughly cleaned, and the stalks should be carefully removed. And dry and fix the twigs to prevent the wind from blowing off. 4. Colonization time. When the soil is thawed in early spring, the sooner the better.
