Management before broadcasting. Before planting, we must carefully prepare the ground and apply enough base fertilizer. Seeding with new high-fat membrane before sowing, can keep warm, moisturize, and swell, improve seed germination rate, and make seedlings strong. Repel underground pests and isolate viral infections. It can also be mixed with a seed coating. After sowing, the straw or sunshade film should be covered to prevent the soil from sticking to the seedlings after the rain. After the emergence of the seedlings, the film is uncovered in time, and the straw can be left in the rows to cover the soil, which can effectively maintain the soil moisture.
Seedling management. Three to four true leaves should be planted once after emergence, and 3-4 plants per hole. Apply fertilizer once every 7-10 days for 2-3 times. When the seedling height is about 20 cm, it is necessary to frame it in time and lead the vines to the shelves. Before flowering, in the young fruit stage and in the expansion period, spraying the fruit and fruit in the timely manner can activate the plant ecological growth positive energy, broaden the plant conduit path, enhance the water absorption and fertilizer absorption of the plant, and improve the fruit yield and quality.
Pest and disease prevention. Autumn sowing green beans are high in autumn, low in rainfall, low in air humidity, so the disease is light. Generally, only 600 times of new high-fat film is sprayed to form a polymer film to prevent pests and diseases. If pests and diseases are found, they must be combined with targeted pesticides for timely prevention and treatment.
