棉花留叶枝栽培的研究现状与应用前景

Status and Application Prospective of Cotton Culture with Leafy Shoots

对近年来关于留叶枝棉花的生长发育以及留叶枝栽培后对棉花产量和品质的影响等方面进行了综述。已有的研究结果证明 ,留叶枝对棉花的营养生长和生殖生长有较好的补偿作用 ,可调节棉花的开花成铃期 ,使棉花的成铃高峰与温光高能期吻合 ,优质桃成铃数和比例增加 ,棉花的产量和品级提高。叶枝的合理利用必将成为现代棉花高效优质低耗栽培技术体系的重要内容之一。

The advances of cotton culture with leafy shoots and their effects on the yield and quality of cotton were summarized. Retaining leafy shoots in cotton culture had remarkably compensatory functions on the accumulation of dry matter, reproduction of cotton. It might lead to closer meet between bolls formatting maximum value period and high energy period of temperature and sunlight, more bolls and higher rate of high-quality bolls, higher fiber yield and grade. The reasonable utilization of leafy shoots of cotton will become important content of high efficiency, good-quality, low cost modern cotton cultural system.
