摘　　要：With early rice variety Zhongzao 39 as test material,this paper investigated the effects of organic fertilizer application rate on seedling quality under no-tillage semi-solid state direct seeding.The results showed that the seedling quality of no-tillage semi-solid direct seeding was better than that of traditional direct seeding,and different application rates of organic fertilizer under no-tillage semi-solid direct seeding also had signi ficant effects on seedling emergence rate,dry matter weight in ground and underground,stem base width,root activity,chlorophyll content and seedling growth index of rice seedlings.When the organic fertilizer dosage was A4(0.10∶1),it was most beneficial to the growth and development of rice seedlings under no-tillage semi-solid state direct seeding,it could effectively improve the quality of rice seedlings and enhance their resistances,the cultivated seedlings could lay a good foundation for high yield of rice in late stage.以早稻品种中早39为材料,研究了有机肥施用量对免耕半固态直播水稻秧苗素质的影响。结果表明:免耕半固态直播水稻秧苗素质总体优于传统直播,而不同有机肥施用量也对免耕半固态直播水稻秧苗出苗率、地上地下部干物质重、茎基宽、根活力、叶绿素含量、壮苗指数等影响显著,其中有机肥与稀泥配比为0.10︰1时水稻秧苗素质最好,可为水稻高产打下良好的基础。
