A reasonable rotation of soybean rhizobium will release a large amount of organic acids. These organic acids will inhibit the growth and development of soybean roots and shoots. Non-bean crops should be planted for 2 years after planting 1 year of soybeans.
Sowing summer soybeans at the right time requires high short-day sunshine, sowing too early will cause early flowering, and will also cause old seedlings and crazy seedlings. Seeding with new high-fat membrane before sowing, can keep warm, moisturize, and swell, improve seed germination rate, and make seedlings strong. Repel underground pests, isolate viral infections, and mix with seed coatings.
It is best to apply 50% of farmyard manure in balanced fertilization soybean field, apply molybdenum fertilizer and boron fertilizer properly, and spray photosynthetic nutrient film fertilizer in time to help plants absorb a lot of light fertilizer, light energy, light, compatible with conventional fertilizer and nutrient supply plant. Growth and development to the limit, one application benefits throughout the year.
The supporting field ditch soybean is a crop with more water demand, and the flowering and pod-forming period is the critical period of water demand of soybean. At this time, the soil drought has a great influence on the yield and quality of soybean. It does not rain for 1 week in summer and should be filled in time. The drought in the flowering stage has a great influence on the number of pods of soybeans. It must be watered in time, and should be paid attention to in the rainy days. At the same time, according to the growth trend of the plant, the protection measures should be determined. If the growth is too prosperous, the cultivating can be carried out by deep cultivating and spraying the flower huawang No. 3, which can promote the transmembrane signal conversion of plant cells, forcing the toppings to vigorously return a large amount of nutrients. The inertia advantage of the tip is rapidly weakened to the capping situation. The main nutrient of the trunk turns to the young fruit development system, which enhances the fruit's swelling vitality, avoids the phenomenon of leaf hypertrophy, and improves the field permeability.
