| 摘 要： | 为了验证水稻"三控"施肥技术、农药减量在当地单季稻条件下的表现,笔者运用控肥技术、生态控制技术与农药减量技术等,并与当地常规管理相比较。结果表明,通过"三控"方案处理后能有效控制总施氮量和基蘖肥施氮量,提高氮肥利用率,防止前期水稻长势过于嫩绿,降低前期病虫害发生概率,减少农药使用量,减轻农田生态环境污染。总之能综合提高有效穗、实粒数、结实率以及增加粒重,从而达到增产的目的,因此经济、社会、生态效益显著。

| 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. |
