采用“3414”试验设计，在大田试验条件下研究了氮、磷、钾肥对水稻产量的影响，并探讨了各种肥料间的互作效应。结果表明，氮、磷、钾肥的施用均可以显著提高水稻产量，且各种肥料配比的增产效果显著优于任一肥料配施。氮、磷、钾肥两两互作对水稻产量均有极显著的影响，当肥料用量处于低中水平时，互作效应均表现为协同促进作用，肥料用量超过一定水平后则表现为拮抗作用。对水稻氮、磷、钾养分吸收影响最大的交互作用分别是氮钾、氮磷和磷钾互作。总体来看，肥料对水稻生长的影响是多方面的，肥料用量及配比应在综合考虑水稻产量及肥料利用率的基础上确定。
採用“3414”試驗設計，在大田試驗條件下研究瞭氮、燐、鉀肥對水稻產量的影響，併探討瞭各種肥料間的互作效應。結果錶明，氮、燐、鉀肥的施用均可以顯著提高水稻產量，且各種肥料配比的增產效果顯著優于任一肥料配施。氮、燐、鉀肥兩兩互作對水稻產量均有極顯著的影響，噹肥料用量處于低中水平時，互作效應均錶現為協同促進作用，肥料用量超過一定水平後則錶現為拮抗作用。對水稻氮、燐、鉀養分吸收影響最大的交互作用分彆是氮鉀、氮燐和燐鉀互作。總體來看，肥料對水稻生長的影響是多方麵的，肥料用量及配比應在綜閤攷慮水稻產量及肥料利用率的基礎上確定。

Based on the“3414”fertilizer experimental design,the effects of N,P and K fertilizer application on grain yield of rice were researched to elucidate the interactive effects among N,P and K in a field ex-periment with four levels of nitrogen(N),phosphorus(P)and potassium(K)fertilizers.The results showed that the application of N,P and K significantly increased grain yield. and the highest yield was found under the joint application of N,P and K fertilizer.The interactions were synergistic when fertilizers Application rates were at lower or moderate 1evels.otherwise they were antagonistic. Grain yield was significantly influ-enced by the interaction between N and K,N and P,P and K,respectively.1t is concluded that the influ-ence of fertilizer on rice growth was various.Which means that fertilizers application rate and ratio should be established with an integrated consideration of several factors including grain yield.
