无为棉区1964年植棉九万六千亩,其中沿江洲圩地区植棉面积达95%。这些地区1964年种植密度比过去有了很大提高,三千至四千株占71.4%,四千至五千株占12.1%,三千株以下占12.1%。种植密度比1963年一般提高20%左右,这是无为1964年取得棉花丰产的一个重要环节。伹密植增产的效果在少数地区表現不同,有的反映密度大了,有的反映密度小了。究竟是密了,还是稀了,我們作了一次調查。从調查情况来看,密度与土質、地下水位、播种期、播种方式和管理技术水平关系很大。
Inaction cotton area Nineteen sixty acres of cotton were planted in 1964, of which 95% were cotton-growing in the area along the Yangtze River. The planting density in these areas increased greatly in 1964 compared with that in the past, ranging from 31,000 to 4,000, from 12,000 to 4,000 to 5,000 and from 12,000 to 3,000. The planting density is about 20% higher than that of 1963, which is an important part of making the cotton yield high in 1964. The effect of dense planting and yield increase is different in a few areas, some reflect the density, and some reflect the density is small. After all, whether it is dense or weak, we made a survey. From the survey situation, the density and soil quality, groundwater level, sowing time, sowing methods and management techniques are of great significance.
