摘 要:2006—2007年在大石桥地区进行水稻小区试验,获得了8个三元二次肥料效应函数方程,函数拟合3个极显著,4个显著,只有1个不显著。确定最佳推荐施肥量N为18~19kg/667m2、P2O5为7~8kg/667m2、K2O为6~7kg/667m2;设计水稻底肥肥料配方为12:20:13;提出"施足基肥、施用调制剂、氮钾分次追施"的施肥模式。The plot experiment of rice was done in Dashiqiao area during 2006-2007, eight functional equations on fertilizer effect were acquired, among which the function fitting conditions were: three equations reached very significant level, four significant and one not significant. The optimum fertilization amount were: N 18-19 kg/667 m^2 ,P205 7-8 kg/667 m^2 and K20 6-7 kg/667 m^2; and the formula of rice ground fertilizer 12:20:13 was put forward; then a fertilization model of "applying enough ground fertilizer, applying modulation preparation, top dressing of NK separately" was proposed
