新疆早熟陆地棉土优塔化学打顶配套栽培技术

Chemical Topping for Early Maturing Upland Cotton in Xinjiang

棉花化学打顶技术具有节本增效、提高时效性和劳动效率、减轻劳动强度、提高棉花抗逆性与产量等技术优势。本文以小区试验与大田示范的结果为依据,探明了该技术的生育期栽培管理目标和长势长相与田间苗情诊断指标,提出了新疆早熟陆地棉土优塔棉花打顶剂化学打顶配套栽培技术规程,以期为大面积生产提供参考。

Chemical topping is a cultivation technique with low cost and high efficiency,and it could improve the timeliness,the labor efficiency and the resistance of the cotton field.Based on the results of plot experiments and field demonstrations,the research indicated the objective of cultivation management and field's diagnosis index during the chemical topping process.The results could provide theory gist for chemical topping technique rules on early maturing upland cotton(Gossypium hirsutum L.)in Xinjiang,especially for Tuyouta agent,and could act as the reference for large-scale cotton production.
