| 摘 要： | 选取五优稻4号为试验材料,对其进行6个不同播种量对秧苗素质影响的试验研究。结果表明:播种量300~400g/m2可获得较好的秧苗素质,采用300~400 g/m2的播种量,第一叶鞘高应可控制在3 cm左右、苗期立枯病发病面积10%、秧苗高度叶龄茎基宽适中、白根数16个、百株地上干重较高。

| Abstract: | The test material used Wu you dao 4, experimental studied effect of seedling quality on 6 seeding rate. The results show that：It can get better seedling quality if seeding rate is 300 g-400 g/m2, the first leaf sheath height should be controlled at about 3 cm, seedling blight incidence area＆lt;10%, moderate of seedling height, leaf age and stem width, the number of root＆gt;16, the 100 plant dry weight of aboveground is higher. |
