什么叫通气育秧?就是在育秧的时候,要坚持湿润管理,使秧田里既有足够的水分,便于种子发芽出苗;又有充足的空气,利于秧苗扎根生长.为什么要实行通气育秧?因为水稻种子发芽、出苗和秧苗生长,既需要水分,又需要空气.可是在一般秧田里,水分和空气之间存在着矛盾.水分多了,空气就少;空气多了,水分就少.秧苗时幼根和幼芽对水分、空气的要求也不一样.幼根生长需要较多的空气,幼芽生长需要较多的水分,所谓“干长根,湿长芽”就是这个道理.目前,有不少 What is the ventilation of seedlings? Is in the nursery time, we must adhere to the wet management, so that seedling fields have both adequate water, seed germination for seedling emergence; sufficient air, which will help rooted seedlings growth. Germination, emergence and seedling growth, both need water, but also the air, but in general seedling field, there is a contradiction between moisture and air.Water is more, less air; air, water is less. And buds on the moisture, air requirements are not the same. Roots need more air for growth, buds require more water for growth, the so-called "dry long roots, wet sprouts A lot
