长江下游是个多雨的麦棉两熟为主的粮棉高产棉区。本区棉花产量的进一步提高,应兼顾同一种植制度中粮、油、绿肥等作物的不断增产。1968年起我们开始了麦套棉高产栽培途径的研究。十多年来,通过对“高度密植”、“小株密植”和“低密壮株”三种途径的比较研究,初步认为“低密壮株”是麦套栽棉花亩产皮棉250斤以上的高产途径。 The lower reaches of the Yangtze River is a rain-fed wheat and cotton-based high-yield cotton-growing areas. The further improvement of cotton production in this area should take into account the continuous growth of crops like COFCO, oil and green manures under the same planting system. Since 1968, we started the research on high-yielding cultivation of wheat straw cotton. For more than a decade, through the comparative study of three types of “highly-densely-planted”, “small-plant densely-planted” and "low- High yielding way.
