Nanometer magnetic fluid for increasing yield and accelerating ripening of soybean
Due to the large temperature change this spring, the closed weeding effect before soybean seedling is poor, the field is small, the phytotoxicity occurs in a large area, the soybean growth is hindered, the root system is poorly developed, the field is seriously stiff, and the growth process is delayed by 7 - 10 days on average.
I. Main performance
1. The new leaves grow slowly, the bottom leaves are yellow, the root rust is red, and root rot occurs in large areas at this stage;
2. The normal growing field only accounts for about 20% of the total area.
3, a single branch less, less than 20 - 30% more.
II. Cause analysis
1. The early climatic conditions are special, the weeds are not well closed, and the grass is weak.
2, rain shower, root damage, phytotoxicity occurs generally.
3. Low temperature and cold (May 17, 18, June 7) caused root rot in some areas.
III. Management Recommendations for the Next Section
Alleviate stiff seedlings, control root rot, promote early maturity and increase yield.
Specific methods: spray high-tech products "nano magnetic fluid" in time according to local experience
5000 times liquid spraying 2 - 3 times, can quickly alleviate stiff seedlings, phytotoxicity, add root prosperity, can quickly alleviate root rot, and can greatly increase production.

Technical points of increasing yield of soybean
1. The ecological types of soybean varieties should be properly selected according to the natural conditions of the local soybean producing areas. The podding habits of soybean can be divided into three types: infinite, limited and sub-finite. Zhumadian, where Lao Zhao is located, belongs to the spring and summer soybean area of the Yangtze River valley. Summer cropping is 120 years and 150 days. Varieties with limited podding ability should be planted in this area, or infinite podding varieties may be selected, so the above phenomenon will occur. Therefore, attention should be paid to the selection of varieties, especially in high soil fertility and rain.

Eight measures to increase soybean production
One is to apply fertilizer to flowers and pods. The growth and development of soybean is the most exuberant in the flowering and podding stage, and it is the period in which soybean needs the most fertilizer in its life. The application of flower and pod fertilizer can reduce the shedding of flowers and pods, promote the fullness of grains and improve the quality. Flower and pod fertilizer should be applied at the early flowering stage, with the combination of nitrogen and phosphorus fertilizer, urea 3kg / mu, phosphate fertilizer 7.5kg / mu, hole application at 5 cm on the side of soybean root, and soil cover fertilizer after application. The second is to spray foliar fertilizer. In addition to the three major elements of nitrogen, phosphorus and potassium, boron, zinc and molybdenum are indispensable trace elements in soybean. Therefore, during the period from flowering to grain filling,
