与露地移栽棉相比，移栽地膜棉的主要栽培效应：一是地温增加；二是生长发育提早，干物质积累重心前移；三是根系发达粗壮，根干重增加，一次侧根数多，生育前期根系活力较强，但二次侧根数减少，生育后期根系活力下降较快；四是产量增加，经济系数高。密度组合优化试验结果：本地区中等肥力棉田亩产皮棉１００ｋｇ的适宜组合为１３３～１５０ｃｍ，密度为３０００～３５００株／亩
Compared with the open transplanted cotton, transplanting cotton membrane of the main cultivation effects: First, increased ground temperature; Second, the growth and development earlier, the dry matter accumulation center of gravity forward; Third, developed root system robust root dry weight increased, the number of primary side and more In the early stage of growth, the root vigor was stronger, but the number of secondary roots decreased, and the root activity decreased rapidly in the later growth period. Fourthly, the yield increased and the economic coefficient was high. Density optimization test results: The middle area of moderate fertility cotton lint cotton 100kg suitable for the combination of 133 ~ 150cm, density of 3000 ~ 3500 / mu
