摘　　要：根据田间区试结果,分析了有机肥与氮磷钾化肥配施对棉麦套作中小麦生物产量和经济产量的构成因素、养分含量及吸收量的影响,结果表明:有机肥与化肥配施能显著提高小麦的生物产量和经济产量,且以中肥最为适宜;增施氮磷钾肥能提高小麦各生育期养分含量和吸收积累量,并且还能增加旗叶的叶面积和叶绿素含量。小麦营养生殖并重时期(拔节至孕穗期),对养分的需求量大,此时土壤中足够的养分,可为小麦高产优质奠定营养基础,此期也是小麦平衡施肥的关键时期。Based on the field test, we analyzed the impact of organic manure and N, P, K fertilizer combined application on wheat biological yield,economic output and nutrient content in wheat/cotton Intercropped. The results showed： Organic and inorganic fertilizers can significantly increase wheat biological and economic yield and middling fertilizer is the most appropriate; Adding N,P,K fertilizer can increase the absorbed accumulation and nutrition in wheat growing period, and can increase the flag leaf proportion and the chlorophyll content. In the period when nutrition growth and procreation growth nutrition are both important,wheat need more nutrition. At this time, there should be enough nutrition in the soil ,and it can establish nutrient foundation to the high yield, and this period is also the key time of wheat＇ s balance - fertilization.
