| 摘 要： | 在施纯氮195kg和P2O5 120kg／hm^2的基础上，研究了钾肥施用量对优质小麦产量和品质的影响。结果表明：施用钾肥可以改善小麦产量因素性状（有效穗数、穗粒数和千粒重）和提高小麦产量。在K2O施用量0～120kg／hm^2范围内，每增施K2O 15kg／hm^2，可增产小麦91．65kg／hm^2。在新乡市土壤养分含量和常规氮磷施用量情况下，施K2O 120kg／hm^2具有显著的增产效应。钾肥施用量对提高粒籽粒品质的作用不明显。

| Abstract: | On the basis of N fertilization(195 kg/hm2) and P2O5 fertilization(120 kg/hm2),the effect of potassium fertilization on the yield and quality of good quality wheat was studied.The results showed that potassium fertilizer could improve the wheat yield and its component character.When the K2O fertilization was 0-120 kg/hm2,wheat yield could be improved 91.65 kg/hm2 with the K2O increase fertilization 15 kg/hm2.On the condition of soil nutrient content in Xinxiang City and normal N and P2O5 fertilization,K2O with the fertilization 120 kg/hm2 could significantly improved the wheat yield.However,the potassium fertilization had no obvious effect on the grain quality. |
