江南地区,春雨连绵,1958年洞庭湖滨一带,早稻秧苗移植前后,就遇上二十多天阴雨,加上间歇性的寒潮,使温度在五月中旬一度降至11℃,禾苗生长衰弱,大量死苗。据粗略估计,—般在20—30%,高者达90%以上。以致不得不犂翻,改种一季晚粳,严重地影响了生产。为了探求在密植情况下减少以至防止死苗,加速秧苗
In the southern part of Jiangsu Province, the spring rain continued. Before the transplanting of rice seedlings in early spring in 1958, over 20 days of rain and rain accompanied with intermittent cold wave brought the temperature down to 11 ℃ in mid-May. Dead seedlings. According to a rough estimate, - as the 20-30%, the highest of more than 90%. As a result, it had to be plowed and turned into late season japonica rice, which seriously affected the production. In order to explore in the case of close planting to reduce and prevent dead seedlings, accelerate seedlings
