In recent years, the area of ​​vegetable soybeans in many urban suburbs has developed rapidly. For example, Zhangwan Street Office in Caidian District, Wuhan City, Hubei, and Gengpu Town in Yunmeng County of Xiaogan City have 10,000 mu of green soybean area. Except for the needs of the local market, most of them are sold to large and medium-sized cities nationwide. Due to the popularity of soybeans in the vegetable market and the sowing of the soybeans during the sowing period, the soybeans in the market have a long period of sales, and the area has continued to expand. According to our investigation in some villages, towns and villages that mainly produce edamame, the income of peasants who plant soybeans in the same way is quite different. The well-paid 1 mu of edamame received over 2,000 yuan, and the difference is less than 1,000 yuan. The reasons for the large differences are many errors in the sowing and fertilizing techniques. During the sowing period, some farm households will sow the seeds of the same species at a point in time. When everyone is concentrated on the market, the mutual bargain price will fall. Some farmers choose to pay no attention to the maturity of the variety, such as early production of early varieties will reduce production. In the application of fertilizer, some farmers believe that soybeans are legumes can not be fertilized, resulting in malnutrition, small grains small; some partial nitrogen fertilizer, nutrient growth is too prosperous, the occurrence of leggy; some planting density is too large, field shade Severe, causing plant lodging; some scabs encounter drought, not timely watering, can not be adjusted with water. These will inhibit the normal growth and development of soybeans. First, we must sow the plants in stages and list them in batches. Soybean varieties are many. If one category of the same traits is planted in one period of time, it will inevitably mature within a certain period of time, and it will flock to the market, block the slow sales channels, and force the market to decline. Therefore, according to the fertility characteristics of soybeans, the method of mulching or seedling transplanting should be adopted to create a warm environment and facilitate the early sowing of soybeans. Very early varieties can be sown in late February, seedlings can be sown at 2.5-3.5 kg/mu, and transplanted from late March to early April; general early-maturing varieties are covered with mulching, and planted in early March. The amount of 4 to 5 kg; summer sowing varieties can be directly in the field in April to May sowing, about 7.5 kg per acre species; autumn sowing varieties in late July sowing, harvest in mid-to late October. The planting density per acre is arranged between 1.2 to 30 thousand plants according to the maturity of different varieties and cultivation methods. Second, it is necessary to balance fertilization and prevent stabilization. Without application of fertilizers or less, the growth of soybeans will be inhibited, and the symptoms of deficiency will appear. This will cause a large number of flower buds, flowers, and larvae to quickly fall off. The lighter ones will fall off by 40% and the heavier ones will fall off by more than 60%. Partial application of nitrogen fertilizer will not only cause leggy, but also buds, flowers, cubs fall off, there will be premature aging. Therefore, it is necessary to emphasize the application of organic fertilizers, generally 50-80 kg of organic fertilizer per acre, 30-50 kg of high-amount NPK fertilizer, or a combination of organic fertilizer on the farm, plus phosphate fertilizer. Kg, potassium 10 to 15 kg. Top dressings were conducted at the seedling stage and the flowering stage respectively. The nitrogen fertilizer was the main seedlings during the seedling stage, and the compound fertilizer was the main component during the flowering and seedling stage, and 0.5% potassium dihydrogen phosphate and 0.01% were applied outside the roots. 0.05% ammonium molybdate was sprayed 2 or 3 times. Conditional farmer households can carry out topping at the early flowering stage, which can play a role in reducing shedding, increasing grain weight, preventing leggy and regulating nutrient balance supply. Third, we must cultivate the soil cultivating and timely irrigation and drainage. The rhizobium of soybean is aerobic bacillus. The cultivating soil not only increases the content of oxygen in the soil, promotes the growth of root hairs and rhizobia, but also raises the soil temperature and prevents lodging of the plants. Weeding and weeding until the closure of the soybeans. Soybeans have the habit of dried flowers wetted, that is, the flowering period is suitable for drought resistance, and more water is needed for the sowing period. According to the determination of the agricultural scientific research department, soybeans need to absorb 1,000 grams of water for every 1 gram of dry matter formed. In this regard, in the early period of young soybeans, we must always manage the gutters so that water can be drained and water can be filtered. In the period of grouting and grouting, in the event of drought, water should be irrigated immediately to adjust fertilizers with water to increase fertilizing capacity, prevent pods from emptying, and ensure timely harvest of large round green beans and morning markets.
