杂交水稻推广后,我县的耕作制度有了新的变化,过去勉强种植双季稻的地区,都改种了单季杂交稻。1982年同1979年相比,单晚面积扩大了1.8万亩。杂交水稻产量高,从而使单晚亩产提高了169斤。这类地区除了继续改进栽培技术,提高单产外,是否还有其他途径呢?本所在常规品种(盐籼203)三年再生稻取得成功的基础上,1983年对汕优6号和赣化2号进行了再生稻栽培试验,取得亩产1,500多斤的好收成。
After the popularization of hybrid rice, the farming system in our county has undergone a new change. In the past, areas that barely planted double-cropped rice all switched to single-season hybrid rice. Compared with 1979 in 1982, single-night area expanded by 1.8 million mu. High yield hybrid rice, so that a single yield per mu increased 169 pounds. In addition to continuing to improve cultivation techniques in these areas, is there any other way to increase yield? Based on the successful three-year ratooning rice variety of conventional indica variety (Yanxian 203), we evaluated Shanyou 6 and Ganhua 2 Number of regenerated rice cultivation experiments, to obtain a good yield of 1,500 kilos per mu.
