摘 要 ：对移栽地膜棉的土壤物理性状及棉株生长生理特点研究表明，移栽地膜棉由于提高了土壤温度和降低了土壤容重等，因而扩大了根系吸收范围，提高了根系吸收功能。根系总吸附面积(ABS )比常规移栽棉高0.5~1.0m2/株，有效吸附面积(ACS)高0.2~0.4m2/株，根系伤流量增加。促进了光合面积的扩大和光合功能的提高，LAI后期下降较少，光

Abstract:Transplant cottons with and without plastic film mulching，abbreviated to T and C in the paper, were investigated in growing and physiological characters. Results showed that the soil temperature increased and the bulk weight decreased because of the film mulching. Thus, in compared with the control
