Last Updated: 2024/11/08, 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: 2 kg of rare earth for every 1 kg of soybean seed, or concentrated at seedling stage and early flowering stage of soybean

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%.
