The northeastern three provinces and Inner Mongolia’s Dongsi League’s spring soybean area are the major soybean producing areas in China. In recent years, the area sown by soybeans has been 367-400 million hectares, accounting for 50% of the country’s total area. Among them, the soybean area in Heilongjiang Province accounts for 30% of the total soybean in China. -35%. However, due to the withdrawal of protection prices for wheat in the northern region, the planting efficiency is poor, the area is drastically reduced, and the thermophilic crops such as corn are subject to accumulated temperature restrictions. Therefore, these areas have changed from the former “maidou area” to the real “soybean area”. Area". The area of ​​soybeans in Jilin Province is not very large, but there is also a problem of heavy grazing. There is a considerable area in the major soybean producing areas in eastern Yanbian and Dunhua regions. Soybean-corn-soybean or soybean-soybean-corn is planted or planted. the way. Greeting or re-influencing the quality and output of a great impact. According to statistics, soybeans sown (ie, planted every other year) have a 6.1% reduction in output compared with normal soybeans, a 9.9% crop yield reduction in one year, a 13.8% crop yield reduction in two crops, and a 19.0% crop reduction in three crops. Soybean re-feeding control technology can reduce the impact on production.

Impact on soybean production. Different environments have different soybean yields. 1 Heavy weight, light weight; 2 West, southwest weight, light north, east; 3 thin, heavy, light land; 4 slopes heavy, low humidity areas light; 5 dry years heavy, rainy young; 6 no fertilization or less Fertilization is heavy, and more fertilization is light; 7 original pods are sown and ploughed, refurbished and lightened; 8 underground diseases and pests are multiple, pests and diseases are lighter; 9 rehabilitative sites are heavy, and new land is light; 10 is heavy and light in irrigation. The eastern four leagues of the Inner Mongolia Autonomous Region are similar to their neighboring provinces. The Huomeng region is similar to the northern region of Heilongjiang Province and the phenomenon is very serious. Today, I would like to talk about three issues. One is the impact of soybeans on the yield and quality of soybeans; the other is the reason why soybeans are replanted; and the third is prevention technology.

Impact on the quality of soybean

The weight of 100-grain soy beans was reduced, the disease rate and the insect-feeding rate increased, and the quality of the products was significantly reduced. According to investigations in Heilongjiang, Fujin, and other places, the average grain weight of soybeans was 18.2 grams, which was 2.7% lower than that of Zhengyu soybeans. The average grain weight of heavy soybeans was 18.0 grams, which was 3.7% lower than that of Zhengyi soybean. The disease rate and insectivorous rate of soybeans planted in soybeans increased by 39.7%, respectively, compared with that of sorghum. The disease-infected soybeans had an increase of 95.5% in the rate of diseased grains and insects, respectively. There is no obvious effect on the protein and fat content in soybeans and short-term weight gain. For three years or more, the protein content of soybeans increased significantly and the fat content decreased significantly. Huaguo Nurse and Wei Miao are new plant growth regulators. Their active ingredients are seaweed polysaccharides, alginic acid, and highly unsaturated fatty acids. They have the ability to promote flower bud differentiation and formation, promote flowering, preserve and protect fruits, and increase fruit setting rate. It promotes fruit enlargement, improves crop quality, enhances its commercial properties, increases yield, and improves soil and other functions.

The soaking of wheat with the “Bonnie” series of plant growth regulators can increase the activity of the seed amylase and respiratory enzymes, speed up the conversion of nutrients, promote respiration, accelerate cell division, promote embryo growth and germination, and increase germination. Potentiality, germination rate, reaching the goal of rapid emergence, Miao Qi Miao Zhuang.

In the wheat seedling stage, using “high-yielding” algae acid high potassium for foliar spraying can promote cell division, promote the formation and growth of leaves, increase the ability of tillering, increase the number of panicles, and lay a foundation for high yield.

Spraying the "Bonnie" series of plant growth regulators at the heading stage can promote the differentiation and formation of wheat spikes. Generally, the wheat can be spiked for 3 to 5 days in advance to extend the grain filling period.

Filling period is a fierce period of nutrient competition. Spraying Huaguo Nurse and Wei Miao can inhibit the senescence of wheat leaves, enhance the photosynthetic capacity of leaves, promote the transfer of nutrients to grains, increase the speed of afforestation, increase grain gain.

During the ripening period, spraying “high-yielding” high potassium alginate can promote the growth of wheat grains, promote the transfer of nitrogen to grains, increase the protein and amino acid content of grains, improve the quality of wheat, promote the ripening of grains, and increase grain weight.

Foliar spraying flower nurses and nurses, Mr. Wei Miao, can also improve the resilience of wheat. At low temperature, Huaguo Nurse and Wei Miao can reduce the electrical conductivity of plants, increase the content of linolenic acid in fatty acids, increase the thickness of wheat leaves, increase the chlorophyll content, increase the water potential of cells, and decrease the freezing point, thereby increasing the cold resistance of wheat seedlings and reducing them. Low temperature caused by rotten seedlings, dead seedlings. Under drought conditions, Huaguo Nurse and Wei Miao can promote the growth of wheat roots and increase the vitality of the roots, thereby increasing the absorption capacity of the roots, thereby enhancing the drought resistance and reducing the damage of dry hot wind in the later period.

At the same time, “more than enough” sodium alginate, which is characteristic of high potassium alginate, is a natural soil conditioner that can increase soil organic matter through the soil or through plants, activate various effective microorganisms in the soil, and make soil organisms. The activity is obviously enhanced, promoting the formation of soil aggregate structure, improving the internal pore space structure of the soil, adjusting the ratio of solids, liquids, and gases in the soil and increasing the release of available nutrients.
