According to studies conducted by the scientific research department, the relationship between soil nutrient consumption and absorption, root exudates, root decay, rhizosphere microorganisms, soil pests and diseases, and rhizosphere environment and plant metabolism are positively mediated and heavily plucked. The main reason for the reduction of soybean production due to heavy cropping is that the root diseases and pests are serious. Due to the serious damage to the root diseases and pests and the deterioration of the soil environment, the normal physiological activities of the soybean root were destroyed, the physiological activity of the root was reduced, the symbiotic nitrogen fixation system was destroyed, the absorption capacity of the root was inhibited, the metabolism of the plant was weakened, and the plant growth was slow. Material synthesis and accumulation are reduced, and soybean yield and quality are reduced.
In the situation where soybeans are inevitably greeted, we must actively adopt strong technical measures to mitigate the dangers of replanting them.
1. Take a reasonable turn to minimize duplication and maintain an appropriate proportion of greetings.
2, choose strong resistance varieties. It can make the rhizosphere microorganisms and adapt to the physiological races of pests and diseases to be mutated, which can effectively reduce the harm of replanting.
3. Reasonable farming, increasing fertilizing materials, improving the soybean breeding environment, performing autumn and soil preparation, applying trace element fertilizers, and supplementing the shortage of trace elements in the reclaimed plots, so as to reduce the harm of replanting crops and increase the yield is an effective way. .
4. Appropriately increasing the planting density, increasing the number of planting plants, and exerting group effects are effective measures for mitigating the hazards. Generally, the planting amount of the soybeans is increased by 8–10% and the sowing quality is improved.
5. Strengthen field management and prevent pests and weeds. The reason for the decline in soybean production and the decline in the quality of soybeans is due to many factors and is the result of the interaction of various unfavorable factors. Therefore, we must start from the many aspects of improving soybean breeding environment, satisfying required nutrients, strengthening soybean self-resistance, and strengthening pest prevention and control, and adopt comprehensive cultivation techniques in order to minimize the number of soya beans. Harmful hazards.
With the opening policy of China's accession to the WTO and the grain market, the problem of soya bean planting is becoming more and more serious, and the reduction in output increases with the increase in the number of years of heavy breeding. According to the survey and research, the reduction in production by 6.1%, the reduction in production by 9.9% in one year, the reduction in production by 13.8% in two years, and the reduction in production by 19.0% in three years, and the decline in the weight of 100-grain soybeans, and the increase in the rate of disease and insects , The quality of the product is significantly reduced, and for three years or longer, the protein content of soybean is significantly increased, and the fat content is significantly reduced.
