1978年,我省杂交水稻制种获得了丰收。全省23万多亩制种田,据大面积调查统计,平均亩产84.7斤,比1977年增产39%,比1976年亩产增加一倍。经过三年来的生产实践证明,只要认真掌握杂交水稻的制种技术,杂交种的产量是可以进一步提高的。1979年,要求在保证质量的前提下,争取全省制种亩产超百斤,达到既优质又高产。制种组合,仍以汕优6号等6号系统为主,防止当家组合不突出和组合单一化。1979年杂交水稻制种生产主要抓“三个提倡”、“四项增产措施”和制种质量把住“四关”。一、提倡连片集中制种,提倡单季制种,提倡建立制种专业队伍。1.提倡连片集中制种。为了加强领导,集中力量进行技术指导,确保杂交种子的质量和制种面积,制种一定要适当连片集中。
In 1978, hybrid rice seed production in our province has achieved a good harvest. According to a large-area survey and statistics, the average yield per mu is 84.7 kg, an increase of 39% over 1977 and a doubling of the yield per mu in 1976. After three years of production practice has proved that as long as a serious grasp of hybrid rice seed production technology, hybrid seed production can be further improved. In 1979, it was demanded that for the sake of ensuring quality, the province should strive for super-kilograms per mu of seed production, achieving both high quality and high yield. Seed combination, still 6 No. Shanyou 6 system-based, to prevent the combination is not prominent and the combination of unitary. In 1979 hybrid hybrid rice seed production mainly focused on “three advocates”, “four stimulation measures” and the quality of seed production to live in “four customs.” First, to promote contiguous seed production, promote single-season seed production, promote the establishment of seed production team. 1. Promote condom production. In order to strengthen leadership, concentrate on technical guidance, ensure the quality of hybrid seeds and seed production area, seed production must be properly contiguous.
