我省早稻育秧期间容易遇到长时间的阴雨低温天气,有时还会出现伤害性低温,使幼苗受寒害而死亡。1965—1966年,笔者曾在临川县唱凯公社搞农业基点工作。这两年早稻育秧期间都出现长时间的阴雨低温天气,并出现三次使幼苗死亡的伤害低温。根据当时详细的气象记载和幼苗生长变化的观察记录,可以说明水稻幼苗死亡、伤害性低温界限及正常转绿所必需的温度条件,对指导生产有一定的参考意义。现将当时记载资料总结整理报导如下。一、温度与苗色变化两年都是3月11日播种,前期用薄膜覆盖。播种后的天气变化与幼苗生长情况两年基本相似。即播后天气晴好,在薄膜的覆盖下出苗快,生长迅速,苗色青绿。以后
During the early rice growing season in our province, it is easy to encounter a long time of rain and cold weather, and sometimes there will be harmful low temperature, so that seedlings suffer from chills and death. From 1965 to 1966, the author once worked as a point of agriculture in Singing Commune in Linchuan County. During the two years of early rice growing seedlings there is a long period of rain and cold weather, and there are three times to make the death of young seedlings damage the cold. According to the detailed records of meteorological records and changes in seedling growth records, you can explain the death of rice seedlings, noxious low temperature limit and the normal temperature required for greening, to guide the production of a certain reference value. At that time, the information recorded at the time was summarized as follows. First, the temperature and seedling color changes are two years of planting on March 11, pre-film covered. After sowing the weather changes and seedling growth are basically similar for two years. The weather was fine after sowing, in the film under the coverage of rapid emergence, rapid growth, seedling green. after
