1, scaffolding in advance. Beans are vine crops, and good scaffolding and early vine introduction can promote the healthy growth of plants. The erection should be carried out as soon as possible, and it can be carried out at the seedling stage. The herringbone frame with more convenient lighting and ventilation and effective pest control can be used for erection.

2. Prune and control vines. Scientific pruning and vine control can effectively improve the ventilation and light environment of plants, rationally adjust the nutrient distribution in plants, and make beans with multi-lateral vines, flowers and pods, which is the most critical means to prolong the harvest period and increase the yield. The specific operation of pruning and controlling vines is as follows: all the lateral branches below the first inflorescence and the leaf buds mixed with flower buds above the first inflorescence of the main vine are drained, and on the basis of retaining 2-3 leaves, all the lateral branches above the first inflorescence of the main vine are topped to remove the core, or topped as soon as the flower buds are seen; When the length of the main vine of the plant reaches 3 meters (about 20-25 knots) or the main vine is covered by the top of the frame, the terminal bud should be removed in time, and the lateral vine will be topped as soon as it sees the flower bud.

3. Pest control. The main diseases of beans are Fusarium wilt, root rot, virus disease and rust, and the main pests are aphids, red spiders, stem borers, stinkbug worms and zebras, so attention should be paid to prevention and control in advance.
