棉花化学打顶整枝技术是用植物生长调节剂与缩节胺喷雾代替人工打顶、整枝、抑制棉花顶端生长,塑造理想株型,改善棉田通风透光,对实现真正意义的棉花生产全程机械化具有重要作用。通过与人工打顶对比,探究化学打顶技术在棉花生产中对棉花生长发育、产量及产量构成的影响及节本增效方面的应用潜力。
Cotton chemical topping pruning technology is the use of plant growth regulators and shrinkage amine spray instead of artificial topping, pruning, inhibition of cotton top growth, shaping the ideal plant type, improve cotton ventilation and light, to achieve the true mechanization of cotton production has Important role. By comparing with artificial topping, the paper explores the influence of chemical topping technology on the growth and development of cotton, the yield and yield composition of cotton in cotton production and the application potentials of cost-effective and efficiency-increasing.
