以转Bt基因抗虫棉新棉33B和杂交抗虫棉农大棉6号为试验材料，设翻耕、旋耕、铁茬3种耕作处理方式，研究了不同耕作方式对棉花生长发育规律的影响。结果表明：不同耕作方式棉花的株高、茎粗和叶面积指数均表现为翻耕＞旋耕＞铁茬，这一规律在2个品种上表现一致。翻耕有利于促进棉花株高和茎粗等营养生长，有助于创建较大的田间群体叶面积，是棉花栽培管理中适宜的耕作方式。

With insect-resistant transgenic Bt gene cotton Xinmian 33B and Nongdamian NO.6 as experimental materials, the growth and development of cotton were researched on three different tillage methods, which including plowing, rotary tillage and direct drilling.The result showed that the orders of different tillage methods on plant height, stem diameter and leaf area index were all plowing >rotary tillage >direct drilling, the trends were identical in both varieties.It indicated that plowing was propitious to promote the vegetation growth of the plant height and the main stem diameter, and increase the leaf area index, which was the feasible tillage method of cotton cultivation.
