First, the reasons for the loss of soybean pods
1. The poor ventilation and light transmission Sunlight is not only the main energy source for organic nutrient production and accumulation, but also the main factor that promotes the rapid development of plants and suppresses leggy. Soybean has good ventilation and light transmission, which can make the climate between the plants and the upper part of the plant consistent, reduce the humidity between the plants, increase the light and temperature, accelerate the leaf area transpiration, and speed up the transportation of nutrients.
2. Unbalanced supply of nutrients. Infertile soils are more detached from the fertile soil than the plants. The plants are long and the shaded soybeans grow normally compared to the plants, and the airy and light-transmission soybean buds fall off; the later formed flower buds are easier to fall off than the early formed flower buds.
3. Unreasonable moisture supply During the stage of flowering and podging of soybean, high humidity, yin and rain, and excessive soil moisture not only reduce the sunshine hours, but also cause the ground temperature to decline, the relative humidity increases, the plants grow longer, the shading degree increases, and the photosynthesis weakens. The synthesis and transportation of organic nutrients increased the loss of calyx.
Second, measures to prevent the loss of soybean buds
1. According to the rational planting of the varieties, according to the principle that the fertile soil should be thin, the thin soil should be dense, the branches with more varieties should be thinned, and the main stem should be planted with the principle of suitable density. The use of isometric on-demand should be used to create a reasonable group structure.
2. According to the increase of fertility of soil fertilization, it is necessary to ensure that there is sufficient nutrient supply during the growth of soybeans, and that the types, proportions, and periods of fertilizer supply are reasonably matched so that soybeans will grow vigorously before flowering and have a certain leaf area index. Accumulate more organics and promote more flowering. The nutrients of flower buds after flowering are guaranteed, preventing greediness, reducing the loss of calyx, and increasing grain weight. In the fertilization type, farmyard manure should be used as a base fertilizer, especially pig manure, chicken manure and other fertilizers containing phosphorus and potassium are preferred. Combined with the application of phosphate fertilizer, the base fertilizer and seed fertilizer should be the main fertilizers during the fertilization period. According to the reproductive performance of soybean, the spraying fertilizer at the initial flowering stage or during the scab stage also has the effect of increasing flower and soil conservation.
3, according to climatic characteristics properly irrigated soybean seedlings to carry out seedlings, the beginning of crusted soil drought, regular irrigation, in order to promote the physiological activity of plants and accelerate nutrient absorption and operation.
4. Strengthen the management of the field and timely eradicate and destroy the weeds, timely control of diseases and insect pests and other cultivation and management measures to improve the growth conditions of plants and flower buds, can also play a role in increasing flowering and protecting crops and increasing yield.
