棉花是纺织工业的重要原料,持续稳定地发展棉花生产,具有十分重要的意义。棉花整个生育期共经历春、夏、秋3个季节,春季气温变化大,出苗前后常出现倒春寒,易造成棉花出苗不齐;夏季气温高、湿度大,易造成棉花疯长,病虫害发生较重;秋季阴雨连绵,易造成烂桃等。因此,提高棉花播种质量,搞好苗期、蕾铃期、吐絮期的管理,是提高棉花产量和品质的关键。针对近年来棉花技术推广中出现的一些新情况和种植中广泛存在的问题,总结概括出棉花高产栽培技术要点。
Cotton is an important raw material for the textile industry. It is of great significance to continuously and steadily develop cotton production. Cotton throughout the growing period experienced a total of three seasons spring, summer and autumn, the temperature changes in spring, emergence of late spring often appear before and after emergence, easily lead to cotton emergence irregularity; summer high temperature, humidity, easy to cause cotton soaring, pests and diseases occurred heavier; Autumn rainy, easily lead to rotten peach. Therefore, improving the quality of cotton sowing, management of seedling stage, budding boll stage and bolting stage are the keys to improve cotton yield and quality. In view of some new situations in cotton technology popularization in recent years and the widespread problems in planting, summarize the main points of high-yielding cotton cultivation techniques.
