摘　　要：针对新疆北部棉区春季气温不稳定,容易引起棉苗延迟型冷害,常造成棉田缺苗断垄,甚至毁种的问题。通过对北疆春季棉花延迟型冷害的实地调查,结合生产实践,总结出"及时查苗与补种、早间苗晚定苗、及时中耕和防治病虫害、及时化学调节和喷施叶面肥"等棉花春季延迟型冷害的综合防治与"选择抗逆性强的早熟品种、适时播种和多种农业预防措施"等综合防御的技术,目的是期望这些技术运用于棉花生产能够减轻棉花生产过程中的春季棉花延迟型冷害造成的损失,为棉花防灾减灾提供参考。In spring,the temperature of Northern Xinjiang cotton area is not stable and easy to form delayed cool injury on cotton seedling,so it often cause the sparse breaks up in cotton field,even ruin the variety. Through field investigation on delayed cool injury in cotton region of Northern Xinjiang and combining with production practice,the comprehensive control and defense technologies on delayed cool injury were summed up. The purpose is to expect these technologies used in cotton production and alleviate the loss of cotton production caused by delayed cool injury and provide references for cotton disaster prevention and reduction.
