| 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：２９４４５ｋｇ／ｈｍ２；Ｐ２Ｏ５：１４０８５ｋｇ／ｈｍ２；Ｋ２Ｏ：１７２５ｋｇ／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/hm 2,P 2O 5 140 8 kg/hm 2, and K 2O 172 5 kg/hm 2. |
