“四干”秧田地膜平铺覆盖保温育秧,是在“三干”通气秧田和地膜平铺的基础上二者结合起来的一种简便而有效的早稻育秧方法。它具有易整地、易管理、成秧率高、育出的秧苗白根多、好拔秧等优点。可以说这种育秧法是目前农村中较好的育秧方法。“四干”秧田的做法一、作畦:“四干”秧田就是干耕、干耙、干做畦加上干畦播芽谷。秧田要在头年11月底至翌年1月中旬这段少雨时节完成干耕干耙干做畦工作,避免到春季因春雨连绵而不易施工。具体做法是:秧田干爽耕翻、耙碎、根据地膜宽度起好秧畦。作畦前可施些腐熟猪牛栏粪作基肥。清好每一条畦沟,使沟内雨天不积水。但畦面不必整平,可留待播种时再整。 The “four dry” seedling film mulching tiling covering thermal insulation, is in the “three dry” ventilation seedling and film tiling based on the combination of both a simple and effective early rice seedling cultivation methods. It has the advantages of easy and neat, easy management, high rate of transplanted seedlings, white roots of seedlings raised, good pull seedlings and so on. It can be said that this method of raising seedlings is now a better method of raising seedlings in rural areas. The practice of “four dry” seedlings First, for 畦: ​​“four dry” seedling is dry farming, dry rake, dry 畦 plus dry 畦 sowing buds. Seedling fields should be completed in the rainy season from the end of November to the middle of January of the following year in dry season, so as to avoid the difficulty of construction due to spring and rain in the spring. The specific approach is: dry tillage plowing, rake broken, according to the width of the film played a good seedlings 畦. For pre-edification can be applied to some rotten pig manure as a base manure. Clean every ditch, so that rain does not ditch within the ditch. But noodles do not have to be level, can be left to sowing re-integration.
