摘要: 采用二次饱和D-最优设计,结合大田调查与土壤肥力测试,于1996~1997年在西昌市西乡乡,对攀西地区主要土壤(黄红冲积性水稻土)上N、P、K施用量及配比与小麦产量的关系进行了研究。结果表明:①小麦的需肥顺序为N > P > K;②土壤钾含量较丰富,施钾量与产量的关系不显著;③小麦产量随N、P施用量的增加而增加,小麦的最佳施肥量为N:294.45kg/hm2;P2O5:140.85kg/hm2;K2O:172.5kg/hm2

Abstract: The relationship between wheat yield and dressed amount and proportion of N,P,K fertilizers on the yellow-red alluvial paddy soil which is the main sail type in Panxi was studied in Xixiang commune of Xichang city from 1996 to 1997. The results obtained are the followings:① The needed order of fertilizers is N > P > K. ②There is no significant relationship between wheat yield and dressed amount of potassium because of richer amount of potassium in soil. ③The wheat yield is increased as the increasing of the dressed amount of N,P fertilizers. The aptimum amount of N,P,K fertilizer is N 294.4 kg/hm2,P2O5 140.8 kg/hm2, and K2O 172.5 kg/hm2.
