Abstract: SField test results show,SThrough coordinated application technology ofS , Can effectively control the total amount of nitrogen fertilizer and tiller fertilizer, Increasing nitrogen use efficiency, To prevent early rice growing too green, Reduce the probability of occurrence of pests and diseases, Reduce pesticide usage, Reduce farmland ecological environment pollution. Reduce farmland ecological environment pollution. besides,Through"Three control"fertilization, It can control the ineffective tillers and the maximum number of seedlings in the early stage of rice,The effective panicle number, seed number, seed setting rate and grain weight increased, So as to achieve the purpose of increasing production, Therefore, economic, social and ecological benefits.
