10 measures to increase soybean production
1. Interseedling: on the basis of the whole seedling, soybean seedlings are carried out when two opposite leaves are unfolded, and the yield is generally increased by 10-20%.
2. Pressing seedlings: when the first compound leaf of some soybean seedlings is unfolded, choose a sunny day at noon and use animal power or machine to induce wood to press along the ridge, which can increase the yield by 8.5-10%.
3. Heart picking: in the early flowering or full flowering stage of soybean, about 2 cm of the top of the main stem is removed by hand, which can increase the yield by 7.2% and 10.8%.
4. Application of rare earth: seed dressing with 2 kg of rare earth for every 1 kg of soybean seed, or spraying rare earth solution with concentrations of 0.03-0.04% and 0.08% respectively at seedling stage and early flowering stage of soybean, the yield can be increased by 15-20%.
5. Spraying ammonium molybdate: before and during flowering, 0.05% ammonium molybdate solution is sprayed once, 25-30 kg per 667 square meters before flowering and 40-50 kg per 667 square meters after flowering, generally increasing production by 5-10%.
6. Spraying paclobutrazol: spraying 50 kg of 250ppm paclobutrazol solution per 667jade rice from branch to early flowering stage can increase yield by about 20%, cure soybean wrinkle mosaic disease and prevent lodging.
7. Spraying sodium bisulfite: 8 grams of sodium bisulfite per 667 square meters, mixed with 50 kg of water, sprayed once in the early flowering stage and full flowering stage of soybean, resulting in an average yield increase of 10.5%.
8. Spraying triiodoformic acid: in the early flowering and full flowering stage of soybean, spraying the solution with the concentration of 100ppm and 200ppm respectively could increase the yield by 5-23%.
9. Spraying Chengling: from the full flowering stage to podding stage of soybean, 20-30ppm solution was sprayed twice with an interval of 7-10 days, each time spraying 50-70kg per 667m2, which could increase the yield by 3-15%.
10. Spraying 802 growth regulator: 20 ml per 667 square meters, 40 kg of water, sprayed during the podding period of soybean, the average yield increased by 10.7%.

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,

How to spray nano magnetic energy liquid on soybean
This year, driven by the market, the enthusiasm of farmers in our province to plant soybeans is extremely high, and they have adopted high-yield practical cultivation techniques to increase investment, realizing uniform seedlings, complete seedlings and strong seedlings, laying a solid foundation for large-scale harvest. Recently, a lot of farmer friend calls advisory farming king nanometer magnetic fluid how to spray? The following is a brief introduction: First, foliar spray: What is the role of Nongwang Nano Magnetic Fluid? Nanometer magnetic fluid belongs to non-chemical products, which is magnetic fluid prepared by magnetic medicine biological engineering method.
