在大豆生长过程中,由于肥水条件比较充足,特别是氮素营养过多,或因密度过大,往往会造成营养生长过旺,枝叶过于繁茂,植株贪青,甚至发生倒状,使籽粒不能正常成熟.遇到这种现象,可在初花期摘心,控制其生长;或喷洒2,3,5—三碘苯甲酸溶液,加速营养生长向生殖生长转化,促进种子成熟.1.摘心大豆摘心是已被生产实践证实了的一项增产措施。摘心后能控制大豆顶端生长优势,使植株体内养分重新分配,促使茎秆粗壮,增强抗倒伏能力;促使分枝长势一致,株形紧凑,有利于通风透光,减少
In the process of soybean growth, due to adequate fertilizer and water conditions, especially excessive nitrogen nutrition, or due to the density is too large, often lead to vegetative over-growth, overgrown branches and leaves, the plant corroded, or even upside down, so that the grain can not Normal maturity.If you encounter this phenomenon, you can pinch the heart of the first florescence to control their growth, or spray 2,3,5-triiodobenzoic acid solution to accelerate the growth of vegetative growth and transformation to promote seed maturation .1. Is a production has been confirmed by an increase of measures. After pinching the top of the soybean can control the growth advantage, so that the plant nutrients re-distribution, to promote stout stalk and enhance lodging resistance; to promote the same branch growth, plant compact, conducive to ventilation, reduce
