摘　　要：综述了耕作栽培技术对新疆棉叶螨种群数量的影响。不同的土壤耕作技术、轮作、邻作、连作年限对种群数量均有显著影响。通过秋耕、冬灌,可破坏棉花害螨的越冬场所,消灭部分越冬害螨,减少越冬基数。连作年限越长棉叶螨的发生越重。前茬为小麦、玉米等单子叶植物的棉田,棉叶螨发生晚而轻;凡是前作为油葵、豆类等双子叶植物,棉叶螨发生早而重。棉花邻作小麦比邻作苜蓿的棉田叶螨发生轻。灌溉、施肥对螨量也有不同的影响。提出了棉叶螨的防治措施。Influence of cultural practices on the population size of cotton mites was stated. Different soil cultivation system, rotation, adjacent cultivation, fixed number of year for continual cultivation all exhibited significant influence on the population size of cotton mites. Through fall cultivation, winter irrigation could destroy the location where pest lived through the winter and it had significant affection to kill some pest which live through the winter and reduce cardinal number. The fixed numbers of year for continual cultivation too long the population size of cotton mites to many. The former batch is monocotyledon plant include wheat, corn etc cotton mites appeared late and light, but former batch is dicotyledon plant conclude legume, etc cotton mites early and heavy. Adjacent field is wheat had mites less than adjacent field is clover. Water and nitrogen have different influence on the population size of cotton mites
