Study on High Yield Cultivation Mode of Cotton in Yellow River Cotton Growing Areas

棉花是黄河流域棉区重要的经济作物,在经济建设和人民生活中都占据着极为重要的地位。近年来,我国棉花生产得到了极大发展,在节省成本、利用资源和提高棉花品质等方面都取得了较大成绩,但降耗增效还存在极大的空间。针对黄河流域棉区的特点以及影响棉花产量的因素,从种植密度和种植方式、灌溉施肥、化控和病虫害防治3个方面,对黄河流域棉区棉花高产栽培模式进行了探讨。

Cotton is an important economic crop in Yellow River cotton growing areas, which occupies a very significant position in economic construction and people＇s lives. In recent years, the cotton production in China has been greatly developed, especially in aspects of saving cost, using resources, improving cotton quality and so on. However, there was still great space in saving and efficiency. In connection with the characteristic of Yellow River cotton growing areas and the factors affecting the cottonyield, the mode of cotton high yield cultivation in Yellow River cotton growing areas was discussed from 3 aspects of planting density and planting mode, irrigation and fertilization, chemical control and pest control.
