化学脱叶不仅是机采棉栽培模式的必要环节,也是促使贪青晚熟棉田早熟的重要措施,为进一步推广脱叶剂的使用,检验机采棉的脱叶效果,奎东农场于2014年就新型脱叶剂品种“棉海”进行了试验、示范,以期筛选出与奎东农场种植栽培模式相配套的脱叶剂品种,达到减少杂质含量、加工清理和生产成本,降低对棉花纤维的损伤度,提高机采棉品级,为产品在推广应用中提供理论依据。基于此,对化学脱叶剂品种“棉海”在新疆生产建设兵团第七师奎东农场实验的情况进行客观的描述与评价。
Chemical defoliation is not only an essential part of cotton picking cultivation mode, but also an important measure to promote premature ripening of late blooming and late-maturing cotton. In order to further promote the use of defoliants and test the defoliation effect of picking cotton, New defoliants varieties “cotton sea” were tested and demonstrated in order to screen out the varieties and defoliants that match with the planting and cultivation patterns in Kuidong farms, to reduce the impurity content, processing and production costs, reduce the cotton fiber The degree of injury, improve machine pick cotton grade, provide the theoretical basis for the promotion and application of the product. Based on this, the chemical defoliants variety “Cotton Sea” in Xinjiang Production and Construction Corps seventh division Kuitong farm experiment objective description and evaluation.
