摘　　要：通过运用氮素调控技术,从根本上改变了传统施肥观念及方法,避免了水稻生长过程中出现的不良现象,实现水稻生育性状的改善,使水稻生育期提前,叶色变化明显,叶片挺立,植株挺拔,抗逆性强;并且水稻的产量性状也得以提高,穗大,籽粒饱满,产量可达到600 kg/667 m2以上。Through nitrogen control technique,the traditional fertilization concept was changed fundamentally and the unfavorable phenomena in rice growing period were avoided.The growing period could be advanced,the color changed normally and the stress resistance increased with forceful plant morphology.The grain yield was able to reach 600 kg/667 m2 due to big panicle and fully ripened kernels.
