早期雹灾后棉花的生长发育特点是:前期生长发育进程明显加快;有效结铃期缩短,结铃相对集中;单株生产力下降。早期雹灾后棉田实现高产的关键栽培技术是早进头水,水肥齐攻,全程整枝,加强化调,充分发挥棉花的补偿能力,最终实现早熟。优质。高产的目标, The characteristics of cotton growth and development after the early hailstorm were: the growth and development of the early stage obviously accelerated; the effective boll stage shortened, the boll number was relatively concentrated; the productivity of the plant decreased. Early hailstorm cotton fields to achieve high yield of key cultivation techniques are early into the head of water, water and fertilizer Qi Gong, the entire pruning, strengthen the tune, give full play to the compensatory capacity of cotton, and ultimately achieve premature. high quality. The goal of high yield,
