摘要
以机插水稻秧苗为研究对象，探讨不同播量及基质配比对机插水稻秧苗素质的影响。结果表明：播量及育秧基质对机插秧苗素质有明显影响，不同播量及不同基质配比的秧苗素质不同，较低播量（每平方米芽谷300-400g）和适宜的基质配比[土与谷壳体积比1：（2～3）]能培育出适合于机插的高素质秧苗。
The seedling quality of mechanical transplanting rice under different sowing densities and raising materials were studied. The results indicated that the effects of sowing densities and raising materials on seedling quality of mechanical transplanting rice were significant. The seedling quality showed different under different sowing densities and raising materials, and different raising materials required correspondingly different sowing densities. In order to cultivate high quality seedling fitting to transplant mechanically, the sowing densities （300-400 g bud per m^2） and the appreciative raising materials [the ratio of volume between soil and chaff was 1 ： （2-3）2 should be adopted in seedling raising.
