在毛主席“备战、备荒、为人民”的伟大战略方针指引下,去年冬种生产坚决贯彻执行“以粮为纲,全面发展”的方针,大力发展晚甘薯套种紫云英、间作油菜的科学实验,取得了较显著成效,为解决早稻基肥问题,加速油料的发展,闯出了一条途径。一九七一年第九生产队十五亩晚甘薯套种紫云英、间作油菜,收油菜籽七百六十斤,平均亩产五十一斤,紫云英亩产鲜草二千三百四十五斤,既增产粮食、油料,又增加肥料,充分利用土地,提高复种指数。甘薯套种紫云英及油菜的好处:一、充分利用土地,扩大冬种门路,不影响甘薯产量,增加冬种收入,实现粮、油丰收。二、增施肥料,培养地力,实现用地与养地相结合,促进 Under Chairman Mao’s great strategic guideline of “preparing for war, preparing for war and for the people”, the policy of resolutely implementing the policy of “taking grain as the key link and all-round development” Intercropping rapeseed science experiments, and achieved remarkable results, in order to solve the problem of early rice base fertilizer, accelerate the development of oil, break a way. In 1971, the ninth production team of late fifteen acres of sweet potato intercropped with milk vetiver, intercropped with rapeseed, received rapeseed a hundred and sixty catties, an average of 51 kilograms per mu, purple cloud acres of fresh grass 2340 Fifteen pounds, not only increase grain, fuel, but also increase fertilizer, make full use of the land, improve cropping index. Sweet potato intercropping the benefits of Astragalus and rape: First, make full use of land, expanding the winter species, does not affect the sweet potato production, increase winter income, achieve grain and oil harvest. Second, increase fertilizers, cultivate fertility, to achieve the combination of land and raising land to promote
