广东顺德县沙窖公社甘蔗面积一万五千亩,属基水地蔗区。为进一步夺取稳产高产,适应耕作制度的改革,扩大轮作面积,恢复地力,提高单位面积复种指数,因而把历年部分较为低产的甘蔗地,进行豆(花生)蔗轮作,既解决社员的食油,又不减少当年甘蔗入厂产量,逐渐建立高产稳产的农田。从一九七五年起围绕这个问题积极开展科学实验,大搞秋植蔗“一造两次收获”的试验,获得可喜的结果,所谓“一造两次收获”,就是于上半年种 Shunde County, Guangdong Province cellar commune cellar area of ​​15,000 acres, is a base water cane area. In order to further seize steady and high yield, adapt to the reform of the farming system, expand the rotation area, restore the earth’s force and increase the multiple cropping index per unit area, we will carry out bean (peanut) sugar cane rotation on some of the more low-yielding sugarcane fields, Do not reduce the sugar cane plant into production, and gradually establish a high and stable yield of farmland. Since 1975, we have actively conducted scientific experiments on this issue and conducted the experiment of “harvesting one harvest with two harvests” of autumn sugarcane to obtain gratifying results. The so-called “harvesting one plant and two harvests” is the first half of the year
