Management method of plum bean planting technology

Plum beans can be divided into white plum beans, green plum beans and purple plum beans according to the pod color, in which the green plum pods are thin and crisp; Purple flat is similar to white plum beans, with thick pods and soft ripe. When sowing, combined with ploughing, 3000 kilograms of decomposed farmyard manure should be applied per mu, and the fertilizer should be mixed evenly with the soil and raked flat. Generally, the direct seeding of plum beans adopts the method of ditching or hole sowing. Plant spacing is controlled at 35-50cm, and row spacing is100-130cm. Generally, 3-4 seeds are sown in each hole, and two seedlings are left in each hole after emergence.

2. Tian Tuan management

Plum blossoms are drought-tolerant, and need to be watered at seedling stage. Generally, they need to be watered 1-2 times at vine extension stage and pod setting stage, and once every 10 day at flowering and pod setting stage. After watering, intertillage and weeding should be done in time, and at the same time, topdressing should be combined to prevent the flowers and pods from falling off or growing white. A small amount of fertilizer should be applied before flowering, and then at pod-setting stage after flowering. Shallow tillage will damage the roots within a year. Pay attention to the reasonable collocation of nitrogen, phosphorus and potassium when applying fertilizer, and pay attention to the application amount of nitrogen fertilizer. Scaffolding can be set up before pulling vines, or vines can be put on the shelf with ropes in time after pulling vines, and vines should be evenly distributed on the hedge frame. When the main vine grows to 1.5 meters, it can be pruned and cored, so that the multi-lateral branches and lateral branches will grow vines and blossom and pod early.

3, pest control

The disease of plum beans is watering, and the pests are mainly aphids and stem borers. Imidacloprid and acetamiprid can control aphids, and attention should be paid to the concentration when using them. Pod moth takes beans as larvae, and in severe cases, it will eat up the whole pod. Spraying 20% pyrethroid 2500 times or 50% fenitrothion 1000 times on the leaves once a week can prevent and control it and avoid drug resistance.
