How to increase soybean production
To increase the production of soybeans, in addition to selecting good varieties, improving the nitrogen fixation capacity of nitrogen-fixing bacteria, and preventing and controlling diseases and insect pests, the following four measures can be taken:
First, skillfully applied lime: Calcium is one of the indispensable elements in the growth and development of soybean. Applying lime with high calcium content can make soybean stems and leaves grow robustly, increase seed setting rate and increase grain weight. Generally, 25 to 30 kg of lime per acre is used as a base fertilizer.
Second, the application of phosphorus and potassium fertilizers: top-dressing phosphorus and potassium fertilizers outside, can promote the full grain, increase production. The topdressing time is from the flowering stage of soybean to the sowing stage. The method is to spray with 100 g of monopotassium phosphate and 70 to 80 kg of water per acre evenly.
3. Respiratory Inhibition: During the initial flowering period of soybeans, spraying with sodium bisulfite 4,5 g per water, 50 kg per acre, spraying once every 7 days, and spraying 2, 3 times, can inhibit soybean photorespiration. The strength of the effect reduces the consumption of photosynthetic products, thus promoting the accumulation of dry matter and increasing the yield of soybeans. However, there are three things to note when adopting this measure: First, this measure is only applicable to early, mid-mature soybean varieties and well-established soybean fields; second, in drought conditions, watering must be performed first, followed by spraying; and third, spraying. Evenly, if it rains within 12 hours after spraying, wait until the rain stops.
