摘　　要：分析了棉花/辣椒、棉花/绿豆、棉花/黄豆对棉花杂交种农艺性状和经济性状的影响。结果表明:棉花/辣椒的产量和经济效应最高,比棉花/黄豆多3.0元/小区、比棉花/绿豆多3.25元/小区,棉花/绿豆的产量和经济效应最低。多因素试验结果还表明:棉花与辣椒、黄豆、绿豆套种,可以提高棉花和其套种作物的经济效益。本实验条件下,在棉花密度32490株/hm2,各套种作物的密度为16245株/hm2的情况下其互作效益最好。Take the cotton, the hot pepper, the mung bean, the soybean as a material, has analyzed the cotton / hot pepper, the cotton / mung bean, the cotton / soybean to the cotton hybrid agronomic characters and the economical character influence. The result indicated that： Cotton interplanting hot pepper＇ s output and economical effect highest ratio cotton interplanting soybean more than 3.0 Yuan/Plot, ratio cotton interplanting mung bean more than 3.25 Yuan/The plot, the cotton interplanting mung bean＇ s output and the economical, The multi - factors test result also indicated that, The cotton and the hot pepper, the soybean, the mung bean interplanting, may enhance the cotton and its interplanting crops＇ economic efficiency. Under this experimental condition, in cotton density 2, 166/The Chinese acre, various interplanting do the density is 1, 083/In a Chinese acre situation it makes the benefit to be best mutually.
