马铃薯与棉花套种是黄淮地区棉田一年两作的主要种植形式之一。多年试验表明,采用二二式宽窄行方式,_一般每1/15公顷产马铃薯2000千克,产皮棉80千克左右,经济效益可观。一、种植方式马铃薯与棉花行比为2:2。棉花实行宽窄行种植。种植带宽150～180厘米,棉花平均行距最大不宜超过110厘米。早春将地整成宽约70厘米的高畦和宽约80～110厘米的低畦。低畦内种两行马铃署,小行距50～60厘米,株距20～25厘米,密度为每1/15公顷4000
Interplanting of potatoes and cotton is one of the main planting forms for cotton fields in Huanghuai area for two crops a year. Years of experiments show that the use of twenty-two wide and narrow line mode, _ generally every 1/15 hectare produce 2000 kg of potato, lint-producing 80 kg, substantial economic benefits. First, the planting method Potato and cotton ratio of 2: 2. Cotton width and width of the plant. Planting bandwidth of 150 to 180 cm, the average maximum spacing of cotton should not exceed 110 cm. Early spring will be integrated into a width of about 70 centimeters tall 畦 and a width of 80 to 110 centimeters low 畦. Two rows of low stamens Malay Department, small row spacing of 50 to 60 cm, plant spacing of 20 to 25 cm, the density of 1/15 hectares 4000
