为了提高制种产量,满足生产需要,我们从1980年以来,进行了杂交水稻制种高产技术的研究,提出了一系列改革措施,经生产实践检验,效果显著。1981年全省制种亩产突破百斤,1983年38万余亩制种田,平均亩产达到232斤,并涌现出亩产过400斤的县1个、过300斤的县12个和过700斤的典型丘块 In order to improve seed production and meet the production needs, we have studied the high yielding technology of hybrid rice seed production since 1980, and put forward a series of reform measures. In 1981, the province’s seed production exceeded one kilogram per mu. In 1983, more than 380,000 mu of land was planted, with an average yield of 232 kilos per mu and a count of 400 kilograms per mu and 12 counties over 300 kilos 700 pounds of typical mound
