摘要： 初步探讨了棉花与萝卜套作的配置模式、经济效益、产量性状和生育性状的变化及状态。结果表明，套作棉田籽棉产量较单作棉（对照）下降4.29%~27.69%，增收萝卜46005~93495kg/hm²，净增产值0.662~1.998万元/hm²，效益非常明显。棉花成铃、株高、果枝等农艺性状生长前期较对照低，中后期与对照差异急剧缩小，表现出较强的补偿性，衣分、霜前花率和病虫害高于对照。萝卜肉质根径粗及单重05-25~06-04时间段增长量最大。

Abstract: The disposition model on cotton and radish interplanting,economic benefit,and the change and state of yields and bear properties were studied Preliminarily.The results showed that seed cotton yield of interplanting cotton field dropped by 4.29%-27.69% than that of single cotton yield(ck),but the radish 46 005-93 495kg/hm² was increased.So net income of 6620-19980/hm² was increased,the benefit was quite obvious.The bolls,plant height,fruit branches and other agronomic characters were lower in earlier growing stage to interplanting cotton field than that of ck,both difference were diminishing rapidly in mid-stage and later-stage,and demonstrated greater compensate properties.However,the lint percent,percentage of cotton output before frost,plant diseases and insect pests wore heighter than that of only plant cotton(ck).The diameter and single weigth of radish pulp root increased most rapidly from 05-25 to 06-04.
