摘要
探索适合鄂北地区麦(油)后直播棉的化学打顶药剂,为化学打顶代替人工打顶提供科学依据。采用化学打顶剂(缩节胺和氟节胺)和人工打顶等不同方式,分析对棉花生长、成铃结构、产量品质的影响以及作用效果差异。结果表明,化学打顶剂(225 g/hm^(2)缩节胺)能够和人工打顶一样有效抑制棉花主茎和果枝顶芽的生长,塑造良好的株型结构,从而促进结铃和吐絮,提升单铃重和增加棉花产量。
To provide the scientific basis for chemical topping instead of artificial toppings,the chemical topping agents suitable for wheat(oil)cotton in Northern Hubei Province were explored.The effects of chemical topping agents(mepiquat chloride and flumetralin)and artificial topping methods on cotton growth,boll structure,yield and quality were analyzed.The results showed that the chemical topper(225 g/hm^(2)mepiquat chloride)could inhibit the growth of the main stem and the top bud of the fruit branch as effectively as the artificial topper,and shape a good plant structure,so as to promote bolling and flocculation,increase the weight of the single boll and cotton yield.
