对移栽地膜棉和移栽棉的土壤物理性状、根系活力、花芽分化特点、干物质积累分配及叶面积变化等进行试验研究，结果表明：移栽地膜棉覆膜能增加土壤温度，保持土壤水分含量相对稳定性，降低土壤容重；花芽分化期提前3 d，花芽分化强度较移栽棉每日每株高0.5个；移栽地膜棉比移栽棉皮棉单产增32.4%，达极显著水平，10月20日前收花量高4个百分点。

Studies were carried out on the soil physical c haracters, roots vigor, flower bud differentiation, accumulation and contribution of dry matter, changes of leaf area and lint yield of transplanted cotton covered with plastic film (TCCPF) and transplanted cotton (TC).The results indicat ed that the soil temperature, the stability of soil moisture and roots vigor increased for TCCPF. Th e intensity of flower bud differentiation were 0.5 per plant per day higher,the sta ge of flower bud differentiation were 3 days earlier and ea rly bolls (before July 15) were 2.6 per plant more than that of TC.The dr y matter c ontributed to reproduction organs also increased. The lint yield of TCCPF before October 20 and total lint yield increased.
