杂交早稻在我省试验、示范、推广,到1987年止,已经历了六年时间。通过一些地区和单位协同研究、系统试验、组织示范的实践证明,杂交早稻在我省优势强,适应性广,引起了各级领导的重视,深受农民群众的欢迎。全省六年来共种植杂交早稻134万多亩,平均亩产475公斤,比同期常规早稻每亩增产80—100公斤(按自然亩计算,下同),纯增收25—30元。1987年全省种植杂交早稻77.4万亩,亩产498公斤,比常规早稻每亩增产100公斤以上。杂交早稻在我省的种植范围,从鄂东南到江汉平原,基本上遍及所有双季稻区,已发展到北纬31
Early hybrid rice in our province test, demonstration, promotion, to 1987, has gone through six years. Through some areas and units of collaborative research, systematic experiments and demonstration of organizations and demonstrations, hybrid early rice has strong advantages and wide adaptability in our province, attracting the attention of leaders at all levels and is well received by peasants. Over the past six years, a total of more than 1.34 million mu of early rice hybrids have been planted in the province, with an average yield of 475 kg per mu, 80-100 kg more than that of conventional morning rice (calculated according to natural acreage), with a net increase of 25-30 yuan. In 1987, 77.4 hectares of hybrid early rice was planted in the province, yielding 498 kilograms per mu, an increase of more than 100 kilograms per mu compared to conventional morning rice. The range of cultivation of early hybrid rice in our province ranges from southeastern Hubei to Jianghan Plain, and basically all the double cropping rice areas have developed to 31
