1980年我县从江、浙引进一批中、早粳品种,进行后季稻品种筛选试验,经过80、81两年台风,淫雨,低温的淘选,初步选出生长期短、成熟较早,抗稻瘟病,耐低温,产量较高的“050”、“564”、“通科粳”、“合交农r”、“联鉴“55”、“联鉴58”等六个适于温室育秧的早粳品种,有关结果如下。 (一)秧苗素质与秧龄:经考查,九个早粳品种80年移栽时,秧龄16天,叶龄除“564”、“联鉴55”、“通科粳”分别为4.4、4.2和4.7外,余均在3.5~3.8之间。81年移栽时,秧龄19天,苗高以“通科粳”最高,为26.5cm,“黎明”最矮,为16.7cm,其他19~23cm; 茎基粗均为0.22~0.27cm,长势健壮;叶龄“74—279”和“联鉴58”为3.6和3.8,余均≥4.1。
In 1980, a series of middle and early japonica rice varieties were introduced from Congjiang and Zhejian in our county to conduct the screening test of the latter rice varieties. After 80, 81 years of typhoons, deformities of rain and cold panning, the initial growth period was short, Six plants suitable for greenhouse, such as “050”, “564”, “Tongkejing”, “Confederation of Agriculture”, “Lianhe 55” and “Lianjian 58” The results are as follows: (1) Seedling quality and seedling age: After examination, nine early japonica varieties were transplanted for 80 years with seedling age of 16 days, leaf age except “564”, “Lianjian 55” and “ Tongkejing ”were 4.4, 4.2 and 4.7, respectively, with the remaining 3.5 to 3.8. In the 81-year transplanting, the seedling age was 19 days and the highest seedling height was“ Tongkejing ”with a height of 26.5cm Short, 16.7cm, the other 19 ~ 23cm; stem base are 0.22 ~ 0.27cm thick, strong growth; leaf age “74-279” and “Lianxian 58” 3.6 and 3.8, the remaining were ≥ 4.1.
