中国农业科学院棉花研究所进行了棉花高密度栽培试验,其目的是探索在目前一般栽培条件下,提高棉花单位面积产量的最高密植限度以及高度密植后棉株的生育表现和生产力。密度分一、二、三、四、五、七、十万七种,种植方式为大小壠和带状种植。大壠二尺四、小壠一尺,大壠二尺、小壠八十,大壠一尺五寸小壠五寸三种;带状种植,畦长一百尺,宽三 The Cotton Institute of the Chinese Academy of Agricultural Sciences carried out a cotton high-density cultivation experiment aimed at exploring the maximum density limit of cotton yield per unit area under current general cultivation conditions and the reproductive performance and productivity of cotton plants after highly inoculation. The density of one, two, three, four, five, seven, seven hundred and seven kinds of planting methods for the size and ribbon cultivation. Large 垅 two feet four, small 垅 a foot, large 垅 two feet, small 垅 eighty, big 垅 one foot five inches Small 垅 five inches three; ribbon cultivation, 畦 long one hundred feet, wide three
