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。
The pot experiment was conducted in 1992-1993 to study the adaptability of cotton and peanut under different nitrogen fertilizer levels and the feasibility of field compounding. The mathematical models of yield and nitrogen fertilizer were established respectively. The results showed that the optimal nitrogen application rate was 0.2167g / kg dry soil and 0.1102g / kg dry soil, respectively. And the peak of nitrogen demand of peanut was earlier than that of cotton, Nitrogen demand and nitrogen complement each other. Prove that the combination of the two in the field is feasible.
