摘要：
現(xiàn)今關(guān)于殘留地膜對(duì)植物土壤性質(zhì)的影響和對(duì)植物生長(zhǎng)發(fā)育的影響研究并不多見(jiàn)。本研究通過(guò)大田試驗(yàn)，在其他限制因子滿足的條件下，通過(guò)人工添加不同數(shù)量地膜模擬不同數(shù)量地膜殘留，有效控制土壤中地膜殘留量，探討地膜不同殘留量下的殘留地膜對(duì)棉花生長(zhǎng)發(fā)育的影響。對(duì)深入理解白色污染的提供理論認(rèn)識(shí)。
Abstract: Dry matter weight of cotton plant and canopy/root ration reduced with adding residual plastic film which destroyed the harmonization of cotton root and shoot so that reduced the production of cotton .So the phenomenon that a certain amount of residual plastic film stimulated root growth was adaptive response of cotton plant ,but there was a negative influence of residual plastic film on biological yield and economic yield, and the more the amount of residual plastic film ,the more obvious the effect of yield reduction.
Key words: white pollution; cotton; residual plastic film; root
