我县从1973年开始试验并大面积推广两段育秧。几年来的实践证明,两段育秧对解决三熟制的季节矛盾,特别是对迟栽的后季稻夺取稳产高产,是一项有效措施。各公社试验比较的结果,后季稻两段育秧比一般育秧法增产20%左右。两段育秧技术是:一、选择好品种选用的品种一般以生育期较长并能相对稳定,秧龄弹性较大,穗型较大、千粒重较高的品种为好。我县后季稻以选用晚粳“农虎6号”为主,搭配早熟晚粳“双丰1号”和“嘉农485”等品种。据车坊、保安、通安等公社农科站后季稻两段育秧品比试验,“农虎6号”亩产768.5斤,比“双丰1号”和“嘉农485”增产44.7斤,比“
My county from 1973 experiments and large-scale promotion of two sections of seedlings. Practice over the past few years proved that the two sections of seedlings to solve the season of three ripening contradictions, especially for late-season late rice to seize high yield and stability, is an effective measure. The commune trial results, the second quarter of late rice nursery seedling raising than the general law about 20% increase. Two sections of seedling raising techniques are: First, choose a good variety of varieties used generally to a relatively long period of growth and can be relatively stable, larger elasticity of seedling age, larger panicles, grain weight higher varieties as well. Late-season rice in our county is dominated by late-season japonica “Nonghu 6” with early-maturing late japonica “Shuangfeng No. 1” and “Jianyun 485” varieties. According to the trial of two sections of seedlings of late rice after Commune Agricultural Station in the workshops, guards and Tong’an, the yield of “Nonghu 6” was 768.5 kg per mu, 44.7 kg more than that of “Shuangfeng 1” and “Jiaonan 485” ,ratio"
