1986年,我省杂交稻制种29.98万亩,总产4602万公斤,亩产153.5公斤,比1985年增产11.3%,一级种子达95%以上,并涌现了一大批高产典型。溆浦、安化、祁东、怀化、资兴、衡东、隆回、洞口8个县(市)亩产突破了200公斤。溆浦县合田乡山下村四组向立才1.2亩威优64制种,总产467.1公斤,亩产389.5公斤,创我省杂交稻制种单产最高纪录。这些高产单位的主要特点是“三多”、“一高”: 1.秧苗带蘗多。1986年杂交稻制种父母本的秧苗素质普遍得到提高。据溆浦、衡东、隆回、祁东等县考查,母本秧田平均带蘗2.7～3个,父本秧田带蘖4～13个,父母本分别比1985年增加
In 1986, the province produced 299,800 mu of hybrid rice with a total output of 46.02 million kilograms and 153.5 kilograms of mu per mu, an increase of 11.3% over 1985 and a first-class seed of more than 95%. A large number of high-yielding typical examples have emerged. Tupu, Anhua, Qidong, Huaihua, Zixing, Hengdong, Longhui, Dongkou eight counties (cities) exceeded 200 kilograms per mu. Huxian County Hetian Township Village four groups to Liuxian 1.2 acres Weiyou 64 species, a total of 467.1 kilograms, 389.5 kilograms per mu, creating a province of hybrid rice seed production record. The main features of these high-yielding units is “more than three ”, “a high ”: 1. Stem with tiller and more. The quality of seedlings of hybrid parents in 1986 was generally improved. According to Xupu, Hengdong, Longhui and Qidong counties, the average number of tillers in maternal seedling ranged from 2.7 to 3, and the number of tillers in paternal seedling increased from 4 to 13
