"Dried flowers wet." The bean moisture management should look at the sky, see the land, see the crops, and comply with the principle of watering after the “dried flowers wet†control. After emergence, flowering, water control, if the good sensation, only in the temporary flowering before pouring a water for flowering needs, and then until the seedlings to the beginning of the fruit only to the first water. After sitting, the plants are prosperous, and the stems and leaves are flowering again. This requires a lot of water and nutrients. This time, the main promotion is to increase the amount of watering so that the soil moisture is stabilized at 60%-70% of the maximum water capacity in the field. In the hot season, use light pouring, ground pouring, morning and evening watering and other methods. Rational fertilization. Based on the application of basal fertilizer and early light fertilizer, it is necessary to top-fertilize for 2 to 3 times during the flowering stage to achieve the purpose of long-term preservation of leaves. Nitrogen fertilizer should be appropriate, and phosphorus and potassium fertilizers should be coordinated to avoid excessive nitrogen fertilizer, resulting in plant growth, leading to falling flowers and affecting the formation of root nodules. Fertilization is mainly based on human fecal urine and manure, and appropriate application of superphosphate, potassium chloride, and ash. Ventilation and light transmission. In order to prevent the beans from being shaded by each other, nylon beans shall be used to hang the vines in the greenhouse. In the open cultivation, the north and south shall be used to form the “people†shaped flower rack. Density of greenhouses should be controlled within 2000 points, the density is too large, mutual shading and not ventilated, will cause only long squat, no scarring. The removal of the old dry yellow leaves and the branches and leaves of diseases and insects in a timely manner will improve the ventilation and light transmission conditions, reduce the consumption of nutrients, and help preserve the flowers. Harvested in time. Timely harvesting can ensure that the quality of the soybean meal is fresh, but also reduces the burden on the plants, and it is conducive to promoting the opening of other flowers, and can also increase the harvest period and increase the rate of scarring. Autumn beans have high temperatures in the early stage and can be harvested about 10 days after flowering. The temperature at the later stage is low and can be harvested 13 days after flowering. Drug treatment. In the flowering stage, 5-25mmp naphthaleneacetic acid or β-naphthyloxyacetic acid, or 2ppm phosphorochlorinated acetic acid, or 5-25ppm "90%" liquid sprayed inflorescence, to inhibit the formation of separation, to prevent flowering Increased scab also has better results.
