一、喷施亚硫酸氢钠:花生与大豆等豆科作物一样,光呼吸作用较强,在整个生育过程中,光合产物要消耗掉1/4至1/3,这就成为花生增产的障碍。而亚硫酸氢钠是一种植物光呼吸抑制剂,将其水溶液喷洒在叶片上后,可以显著降低光呼吸强度,减少养分消耗,增加干物质积累,促进花生早熟,可使花生增产10％以上 花生喷施亚硫酸氢钠,宜从初花期开始,每隔10天喷1次。共喷2～3次。在晴天的上午露水干后至
First, spraying sodium bisulfite: peanuts and soybeans and other leguminous crops, strong photorespiration, during the entire reproductive process, photosynthetic products to consume 1/4 to 1/3, which has become an obstacle to peanut production . Sodium bisulfite is a kind of plant photo-respiration inhibitor. When its aqueous solution is sprayed on the leaves, it can significantly reduce the photorespiration intensity, reduce the nutrient consumption, increase the dry matter accumulation and promote the peanut precocity, which can increase the peanut yield by more than 10% Spraying peanut sodium bisulfite, should start from the beginning of florescence, spraying every 10 days 1. A total of 2 to 3 times spray. In the sunny morning dew dry to
