摘要 采用低棚深沟肥床旱育秧的技术,培育迟中稻中大苗。结果表明,该技术能在夏季高温多雨条件下,省工节本地控制苗床温湿度,以利于秧苗旱育生长。旱育秧的叶龄、苗高、干重和单株分蘖数与同期水秧相近;苗高比水秧矮1/3;栽后3d发根数比水秧多50%。 With technipues of plastic film Shelter,deep ditch,fertile soil and dry nursery,middle-large seedlings of late middle rice were raised. The results was as follows: the temperature and humidity of seedling-bed was controlled in condition of high temperature and rainfall. Seedling age,dry matter weight per unit,tillers from the dry nursery were similar with those from the water nursery;the hight of seedling was short one third than that from the water nursery,After being transplanted,the number of new roots of seedling from the dry nursery were increased over 50% than that from the water nursery.
