摘　　要：生根粉通过调控大田作物重要酶的活性,促进根的分裂,使不定根原基萌发,降低因移栽等栽培措施引起的根系损伤,缩短缓苗期,促进根系早生快发,促进其生长发育。大田作物生理生化变化是其新陈代谢的体现。实践表明,生根粉运用于花生、小麦、棉花、水稻等大田作物,通过改变其生理生化指标,有利于促进体内营养物质的形成;对烟株喷施生根粉能使其ATP含量、游离氨基酸总量、叶绿素含量等有明显增加,提高育苗成活率和增强抗性。适当喷施生根粉还有利于提高大田作物的产量和经济产值,对其内在质量的提升也有明显效果。Through the regulation of key enzyme activity,the rooting power can promote the root division and adventitious root grow rapidly,reduce root injury caused by transplanting cultivation measures,shorten the day in slow seedlings and promote root early-onset,achieve the goal of improving yield and quality.Some field researches showed that rooting powder could promote the photosynthetic and promote plant nutrients formation of crops by changing their physiological-biochemical characteristic,thereby increased the average yield and economic output.Rooting powder has the ability to improve the quality of tobacco seedlings,enhance the resistance of tobacco,promote tobacco nitrogen assimilation,regulation of root, stem,leaves nicotine content,improve the quality of tobacco and economic level,to promote greater harmony in the chemical composition of flue-cured tobacco.Proper spraying of rooting powder can improve the yield and economic output of field crops,besides,it also has effects on improving the inherent quality of crops.
