用冷储１ａ的汕优６３种子为试验材料，采用塑料农膜覆盖旱育秧方法，在只浸种不催芽情况下，探讨浸种时间长短与出苗之间的关系。结果表明：农膜覆盖旱育秧，陈稻种可以浸种后不催芽直接播种；浸种４２ｈ左右，种子出苗整齐一致，达最高的出苗率和成苗率。 Using cold storage 1a of Shanyou 63 seeds as test material, using plastic plastic film covering dry nursery method, only soaked in non-germination case, to explore the relationship between seed soaking time and emergence. The results showed that the plastic film covering dry nursery seedlings, Chen rice species can be sowing seeds without direct seeding; seed soaking 42h or so, seed germination neat, the highest rate of emergence and seedling rate.
