1. Seedling management is the foundation and management is the key. According to the different requirements of different growth periods of soybeans on the environment and the characteristics of soybeans in different growth periods, corresponding management measures are adopted to obtain high yields. specific measure:
1 check seedlings, make up seedlings. After the emergence of soybeans, check seedlings and seedlings were used to ensure seedlings were fully grown and time seedlings were removed from the seedlings. To achieve full seedlings and seedlings is an important part of cultivation. Filling seedlings can be planted or transplanted.
2 Strengthen cultivator cultivators. Immediately after the seedlings, cultivating and cultivating grasses are conducted. The cultivator will plant at least three or four times of cultivating in the whole growth period, and the peasant pods will have three rounds of spheronization. The cultivator depth varies from shallow to deeper and shallower with the growth of the root system. With the cultivator grazing grass, to the roots of the soil, and gradually cultivated earthworms, conducive to drought, resistance to collapse, and drainage. To see seedlings and irrigation, thin ground without applying base fertilizer, in order to protect the seedlings can be topdressing in the seedling period, ammonium 5-7.5 kg per mu, superphosphate 7.5-15 kg, to promote branch formation and flower bud differentiation All have a good effect, but also beneficial to rhizobia and development, enhance nitrogen fixation capacity. If the lack of water is properly irrigated, it can promote the differentiation of flower buds to form a high-yield plant shape. If the seedlings have leggy seedlings, in the sunny days at noon on the first compound leaves to suppress sturdy ridge, can play the role of pressure seedlings to promote root. With the above treatment, the output can be increased. According to domestic reports, it can increase production by 8.5%; foreign reports can increase production by 13%.
2. Flowering and fruiting stage management Flowering and fruiting stage mainly strives for more flowers, early flowers and flowers, preventing flower buds from falling off, increasing flowering, and increasing seedlings. This is the task of the management center during this period. It depends on the management of seedlings, the control of conservation and control, the control of high-yielding fields, the avoidance of premature closure of ridges, and the maximum leaf area at the end of flowering. Specific measures are: continue to rake the grass before mulching, see the seedlings as appropriate to the water and fertilizer, weak seedlings at the beginning of the flowering period topdressing, strong seedlings do not top fertilizer to prevent leggy. During the flowering period, the phosphate fertilizer has obvious effect. At this point, the area of ​​soybean leaves reached the maximum, the water consumption increased, the transpiration intensity peaked, and the water demand peaked. When the color of the leaves appears old and green, and the noon leaves are wilting, it is necessary to water them in time, or the buds will fall off. At the end of the flowering period, picking the top of the heart (2 inches at the top) can prevent lodging, promote the redistribution of nutrients, and provide more flower buds. Soybeans with limited pod habits and infertile soil soil are not suitable for topping. High-yielding fields can be used to prevent lodging and prosperous growth. Promptly prevent and treat pests and diseases, otherwise it will cause no harvest during the rainy season.
3. The management of ripening of granules during ripening of husks is the period when soybeans accumulate most dry matter, and it is also an important period for yield formation. Promote the transfer of nutrients to the grains, promote grain full weight, early maturity is the center of management during this period. The lack of water during this period will increase the number of maggots and pods, and the weight of 100 grains will decline. In case of drought and no rain in autumn, it should be watered in time, and attacking grains with water has a significant impact on improving yield and quality. Soybean yellow ripe for the appropriate period. When the seed moisture content reaches 13%, it can be stored.
