龙胜县山高水冷,日照少,给种双季稻带来很大的局限性,在海拔较高的地方种双季稻往往不如一季中稻强。而种植再生稻,利用再生稻生育期短、省种、省工的特点,多收一季粮,对发展山区粮食生产将不失为一条有效的途径。1979年我们在田寨等六个点试种再生稻2.5亩,取得亩产超千斤。1980年在仰寨等5个点试种12亩,盐汕203、广二矮5711、金围矮3个品种,分别获得亩产1400斤、1600斤和1200斤。1981年又在9个公社60个生产队和180户社员试种404亩(分布在海拔200—700多米),验收头季370亩,亩产612.4斤;再生稻232亩,亩产273斤,全年合计亩产885斤。
Longsheng County, high water-cooled, less sunshine, double-cropped rice to bring great limitations, in the higher elevations of double-cropped rice is often not as good as a season of rice. The planted ratooning rice, the use of ratooning rice growth period is short, provincial species, provincial workers characteristics, more than a quarter of grain, the development of mountain food production will be an effective way. In 1979, we experimented on 2.5-acre crop of rehmannia at six locations in Tianzhai and obtained a super-kilogram per mu. 1980 in Yangzhai and other five points planted 12 acres, salt Shantou 203, Guang Er short 5711, Jinwei dwarf 3 varieties were obtained per mu 1400 pounds, 1600 pounds and 1200 pounds. In 1981, another 404 production units (distributed over 200-700 meters above sea level) were experimented with 60 production teams and 180 social workers in 9 communes and an inspection of the first quarter of 370 mu with a yield of 612.4 kg; 232 mu of regenerative rice and 273 kg of mu per mu, The total annual output of 885 pounds per mu.
