摘要
化学脱叶催熟技术是棉花机械收获的重要前提,是机采棉综合农艺配套技术的关键环节。合理施用脱叶催熟剂能够提高机采棉的脱叶吐絮质量,降低籽棉的含杂率,对解决新疆棉花品质问题具有重要意义。然而,当前棉花脱叶催熟剂存在有效成分单一、剂型同质化严重、喷施装备及喷施技术落后,造成籽棉含杂率高,严重影响棉花品质。本文评述了机采棉脱叶催熟剂及其施用的研究现状,总结提出了棉花脱叶催熟剂存在的问题及解决途径,对今后棉花脱叶催熟剂减施增效的前景和研究方向做了展望。
Chemical defoliation and ripening is the important premise of machine-harvested cotton,and also the key of agronomic measures technology of machine-harvested cotton.Appropriate and safe harvest aids will improve timing and facilitate harvest of cotton.However,there are only few types of the cotton harvest aids active ingredients,and with serious formulation homogeneity as well as the backward equipments and technologies of cotton harvest aids spraying lead to high impurity content of seed cotton and seriously affects the quality of cotton.In this paper,the research status of harvest aids and its scientific application were reviewed,and the existing problems and solutions of cotton harvest aids were summarized.The prospect and research direction of reducing application efficiency of cotton harvest aids in the future were prospected.
