摘　　要：用小区试验的方法,研究了水稻不同播量对秧苗素质及产量的影响,结果表明:水稻旱育苗播种芽200～750gm/2,随着播种量的增加,叶龄、根数、地上干重、分蘖率、成苗率明显下降,产量逐渐降低。现有的生产条件,最佳播种量应为200～250gm/2,育出的秧苗壮,水稻产量高,应在生产上推广应用。Using the method of small plot experiment to research the different seeding quantity had the effect on seedling diathesis and yield, the result indicated that the leaf age, quantities of root, overground weight, ratio of tiller and stocking per cent can decline distinctly along the seeding quantity was from 200 g/m2 to 750 g/m2, at the same time the yield can decline gradually. Based on the existing condition, the best seeding quantity should be 200～250 g/m2, it can breed the stuggy seedling and the high yield, it should be popularize on production.
