亚硫酸氢钠是一种植物光呼吸抑制剂,它被大豆、花生叶片吸收后,能抑制光呼吸作用的强度,减少大豆、花生由于光呼吸作用对光合产物的消耗,可促进于物质积累,提高大豆、花生产量。据试验,在大豆花期喷洒两次亚硫酸氢钠增产10％,初荚期喷洒增产8.9％,并提早成熟3—5天。喷洒方法:每亩地喷1次亚硫酸氢钠仅用药3—4克,加水50公 Sodium bisulfite is a plant photo respiration inhibitor, which is absorbed by soybean and peanut leaves, can restrain the intensity of photorespiration and reduce the consumption of photosynthesis products of soybean and peanut due to photorespiration, which can promote the accumulation of substances, Increase soybean, peanut production. According to the test, spraying sodium bisulfite twice in the soybean flowering stage increased the yield by 10%, spraying in the early podding stage increased by 8.9% and prematurely matured for 3-5 days. Spray method: 1 spray per mu of sodium bisulfite only medication 3-4 grams, add water 50 kilometers
