广大劳动农民和农业科技工作者,为了防止早稻烂秧、培育壮秧,不断地改进育秧方法。从大畦水育秧到合式秧田水育秧;后改进为湿润育秧;继而改进为薄膜育秧、温室育秧(部分采用),等等。据调查,当前农业生产上常用的育秧方法,仍然主要是湿润育秧。笔者在试验研究和生产实践中认识到,实行湿润育秧,在播种后如适逢一段晴好天气,确实能改善稻芽的供氧状况,为扎根长芽创造有利条件,可以基本上解决烂秧问题。但是,我省水稻区春季多雨,一旦遇雨,必须及时灌水护秧,雨后又要立即排水露秧。这样时灌时排,实质上仍是水育秧。为了解决这个问题,1974年我们开始在播种塌谷后 The majority of laborers and agricultural science and technology workers, in order to prevent early rice rot seedlings, nurturing strong seedlings, and constantly improve the method of raising seedlings. Watering and planting seedlings from the large waterway to the combined seedling watering seedling; later improved to wet seedling; then improved to film seedling, greenhouse seedling (used in part), and so on. According to the survey, the current methods of raising seedlings in agricultural production are still mainly wet seedlings. In experimental research and production practice, the author realizes that implementing wetting and seedling planting can meet the needs of a good weather after sowing, which can indeed improve the oxygen supply of rice buds and create favorable conditions for rooting long buds, which can basically solve the problem of rotting seedlings . However, the rice area in our province is wet in spring, and in the event of rain, it is necessary to timely seed the rice seedlings with water and drain the seedlings immediately after the rain. This irrigation time row, in essence, is still watering seedlings. In order to solve this problem, in 1974 we started sowing after the collapse of the valley
