1965年浙江省早稻播种期间长期低温阴雨,浙北各地有很多生产单位发生了不同程度的烂秧。同时,秧苗生长缓慢,于3月底4月初播种的,都要到4月14～15日才出苗,4月下旬大都是真叶伸出而尚未展开,秧苗矮黄,因而比常年延迟插秧5～10天。但插秧以后,遇到比常年偏高的温度,又加上精耕细管,早稻转青发棵快,形成迟栽早发,因而最终取得了早稻大丰产。 In 1965, long-term low temperature and rainy weather occurred during sowing of early rice in Zhejiang Province. There were a lot of rotten seedlings in many production units throughout northern Zhejiang. At the same time, the slow growth of seedlings, sowing at the end of March early April, must be April 14 to 15 before emergence, in late April mostly true leaves reach yet to start, seedlings short yellow, and thus delayed than usual planting 5 ~ 10 days. However, after transplanting, encountered higher than normal temperatures, coupled with intensive farming, early rice turn green quicksod, the formation of late premature, thus eventually achieved a big yield of early rice.
