New Technical Essentials for Autumn Sowing of Green Bean

Pre-broadcast management. Careful soil preparation and adequate base fertilizer should be applied before sowing. Seed dressing with new high-fat film before sowing can keep heat, keep moisture, absorb swelling, improve seed germination rate and make seedlings strong. Repelling underground pests and isolating virus infection. It can also be mixed with seed coating agent. Straw or sunshade film should be covered after sowing to prevent the soil from hardening and sticking seedlings after rain. Uncover the film in time after emergence, cover the straw can leave the straw between the rows to cover the soil, can effectively maintain soil moisture.

Seedling management. When there are 4 true leaves after emergence, the seedlings should be interspersed once, and 4 plants should be left in each hole. Thin fertilizer was applied every 10 days for 3 consecutive times. When the seedling is about 20 cm high, it is necessary to set up the frame in time and draw the vine on the shelf. Spraying Zhuangtieling in time before flowering, young fruit stage and expansion stage can activate plant ecological growth positive energy, broaden plant vessel path, enhance plant water absorption and fertilizer absorption, and improve fruit yield and quality.

Pest prevention. Due to the crisp autumn air, less rainfall and low air humidity during the growth period, the disease is relatively mild, so it is only necessary to spray 600 times of the new high-fat film to form a layer of polymer film to prevent diseases and insect pests. If diseases and insect pests are found, we must cooperate with targeted agents to control them in time. (Earth)
