摘    要:
通过测土配方项目"3414"田间试验方案,研究不同肥料配比对小麦的产量影响,建立天长地区肥料效应函数模型,获得该地区最佳施肥量为氮(N) 18.32kg/667m2,磷(P2O5) 3.10 kg/667m2,钾(K2O)4.71kg/667m2,经济最佳产量为410.22 kg/667m2.结果表明:氮磷钾配合施用处理的产量显著大于缺氮处理、缺磷处理及缺钾处理的产量,且氮肥的增产效果最为明显,其次是磷肥和钾肥.

关 键 词:3414  小麦产量  氮磷钾  肥料配比

Abstract:
Through the soil testing project 3414 field experiments,we researched the effect of combined application of fertilizers on wheat and established the fertilizer effect function model of local wheat of Tianchang city and got this conclusion: the best quantity fertilizer is: nitrogen(N) 18.32 kg/667m2,phosphorus(P2O5)3.10 kg/667m2,potassium(K2O) 4.71 kg/667m2,the best economic output is410.22 kg/667m2.The result indicates that,the appropriate combinations of fertilizers on wheat yield is significantly greater ...
