我区棉区大多是盐碱土,土壤比较瘠薄,肥力低,同时,由于棉花面积比较集中,加以肥源不多,在播种季节往往出现粮棉争肥的矛盾。长期以来棉花产量不易很快提高,也影响粮食产量的迅速增长。为了解决棉田肥料不足和棉、粮争肥的矛盾,达到用地和养地相结合,我们从1963年秋天开始至1964年,在碭山、肖县等棉区进行了棉田套种苕子的示范工作,取得了一定的成效。
Most cotton areas in our district are saline-alkali soil with relatively infertile soil and low fertility. At the same time, due to the relatively concentrated area of cotton, few fertilizer sources are used, and conflicts often arise between grain and cotton in the seeding season. Long-term cotton production is not easy to increase quickly, but also affect the rapid growth of food production. In order to solve the problem of insufficient fertilizers in cotton fields and the conflict between cotton and grain for fertilizer and the combination of land use and raising land, we started the demonstration project of intercroping prickly heat seeds in cotton fields in Dangshan and Xiaoxian from the autumn of 1963 to 1964, Has achieved some results.
