摘要
系统报道了棉花生长后期对叶片营养进行综合诊断的有关参数（Ｎ／Ｐ，Ｎ／Ｋ，Ｋ／Ｐ，ＮＰ，ＮＫ，ＰＫ），经田间施肥试验及示范推广，其准确度达９２％，具有较大的可靠性，可与棉花优化测土施肥结合进行，在生长后期进行叶片营养综合诊断使用。
Reports systematically the parameters of the comprehensive diagnosis of the leaf nutrition in cotton in its late growth stage (N/P,N/K,K/P,NP,NK,PK). According to field fertilization experiment and demonstration, the accuracy of this diagnosis was as high as 92%. It is of high reliability and can be used in the comprehensive diagnosis of the leaf nutrition in cotton in its late growth stage combined with optimum soil testing and fertilization.
