南方二晚育秧期间,气温高,雨水多,秧苗生长快。但是塑盘育秧抛栽秧龄不能太长,秧苗不能太高。否则,秧苗串根、黄化,抛秧后倒秧多,立苗慢。所以必须实行“三控”,使秧苗矮化(?)壮。方法是: 一、水控 采用湿润秧床,以糊泥配肥做营养土的,播种后3天左右,畦沟里保持半沟水;采用旱床,以干细土配肥做营养土的,播种时浇透水。不论
South two days after the seedling, high temperature, rain and more rapid growth of seedlings. However, plastic plate throwing seedling throwing seedling age can not be too long, seedlings can not be too high. Otherwise, the seedling roots, yellowing, throwing transplanted seedling more, standing seedlings slowly. Therefore, we must implement the “three control” to seedling dwarf (?) Zhuang. Method is: First, the use of water-controlled seedling water bed to make mud with mud nutrient soil, sowing about 3 days, the ditch to maintain half-ditch water; the use of dry bed, dry fine soil with fertilizer to do nutrition soil , Sowing water when sowing. whether
