摘　　要：１９９４～１９９５年在不同施肥条件下研究了棉铃干物质动态累积规律。结果表明：Ｎ、Ｐ、Ｋ单施或配合施，均有利于棉铃各部分干物质的累积，Ｎ对铃壳干物质累积有明显促进作用，Ｐ、Ｋ有利于棉纤维和种子干物质的增加，Ｎ、Ｐ、Ｋ对棉纤维品质有明显的改进作用。During 1994-1995, field experiments were carred out with the medium maturing cotton cultivar “Zhong cotton No.12”, aiming to determine the effect of different fertilizer applying treatments (N,P,K,NPK,CK) on the dry matter accumulation of cotton boll and quality of fiber. The results showed that the dry matter accumulation of cotton boll was significantly affected by different applications of fertilizers, and the quality of fiber was improved by the applications of N,P,K as well.
