摘　　要：１９９２－１９９３年通过盆栽试验，对不同氮肥水平条件下棉花和花生的适生效应及田间组配的可行性进行了研究，并分别建立了产量与氮肥用量的数学模型。分析认为，二者的最佳施氮量分别为０．２１６７ｇ／ｋｇ＿（干土）和０．１１０２ｇ／ｋｇ＿（干土），并且，花生的需氮高峰比棉花早，表现出棉花与花生在需氮量和需氮时间的互补作用。证明二者在田间组合搭配是可行的。Plot experiments were conducted to study the adaptability of cotton and peanut atdifferent rates of N application and the feasibility of their combination in the field from1992 to 1993,and the mathematical models were establishedThe optimal application of tocotton and peanut was 0.2167g/kg dry soil and 0.1102g/kg dry soil respectively. the peakstage of N uptook by peanut was eariler than that by cotton ,which showed the comple-mentarity of cotton and in peanut the rate and uptaking time of N.so,it is feasible for cot-ton to combine with peanut in the field.
