摘　　要：为探明基质育秧和营养土育秧对水稻秧苗素质和产量的影响,以台湾香稻为试验材料,设置了常规盘基质育秧、可降解盘基质育秧、不可降解盘基质育秧、常规盘营养土育秧、可降解盘营养土育秧、不可降解盘营养土育秧6种不同育秧方式,进行秧苗素质、植株形态和产量的差异比较。结果表明,可降解盘基质育秧相对于其他育秧方式,秧苗生长速度快,茎基部肥大,叶片较长较宽,秧苗素质好;大田期表现为植株生长健壮,分蘖力强,产量较高。In order to explore the effects of the regular disc substrate seedlings （F1）, biodegradable plate substrate seedlings （F2）, non-biodegradable plate substrate seedlings （F3）, regular disc nutrient soil nursery （F4）, biodegradable plate nutrient soil nursery （F5） and non-biodegradable plate nutrient soil （F6） on seedling quality, morphological characters and grain yield, an experiment was carried out, using Taiwan Xiandao as material. The results showed that among the six seedling raising methods, the seedling growth speed, diameter base hypertrophy, wide blade and seedling quality of F2 treatment were the best. In field stage, the plant growth and tillering ability of F2 treatment was the best. Compared with F4 and F6 treatment, the yield of F2 treatment was increased by 24.87% and 62.32%.
