摘　　要：研究不同床土调制剂对水稻秧苗素质的影响,结果表明:粒滚粒水稻床土调制剂的秧苗素质最佳,株高、茎基宽、最长叶长、第一叶鞘高、单株分蘖、百株地上鲜重、百株地上干重都高于其他4个处理;叶龄、最长叶宽、根数也都达到壮秧标准。其次是禾美家水稻壮秧剂单株分蘖与粒滚粒相同,叶龄、最长叶宽、根数均高于其他4个处理;株高、茎基宽、最长叶长、百株地上鲜重、百株地上干重仅次于粒滚粒。金米海壮秧剂的叶龄、根数仅次于禾美家,株高、最长叶长、百株地上鲜重、百株地上干重均低于粒滚粒和禾美家;茎基宽、最长叶宽、单株分蘖都高于CK。绥禾农科水稻壮秧剂叶龄与金米海基本相同,茎基宽、最长叶宽、单株分蘖均低于粒滚粒和禾美家;最长叶长、根数、百株地上鲜重,百株地上干重均高于CK,但这一调制剂较其它4个处理秧苗矮,株高未达到壮秧标准,第一叶鞘也短,说明此种调制剂对秧苗的生长起到了矮化抑制作用。The effects of different soil modulator of bed on rice seedling quality were studied.The results showed that rice bed soil conditioning preparation of Ligunli was the best.Plant height,stem base width,longest leaf length,first leaf sheath height,tillering per plant,fresh weight per hundred plants and dry weight per hundred plants were all higher than those of the other four treatments.The leaf age,the longest leaf width and the number of roots have reached the standard of strong seedling.Secondly,the tillering per plant of Hemeijia rice shoots growth promoter was the same as the Ligunli rice shoots growth promoter,the leaf age,the longest leaf width and the number of roots were higher than the other four treatments.Plant height,stem base width,longest leaf length,ground fresh weight of 100 plants,ground dry weight of 100 plants are second only to Ligunli rice shoots growth promoter.The leaf age and root number of Jinmihai rice shoots growth promoter were second only to Hemeijia rice shoots growth promoter rice shoots growth promoter,plant height,longest leaf length,fresh weight and dry weight of 100 plants were lower than those of Ligunli rice shoots growth promoter and Hemeijia rice shoots growth promoter.Stem base width,longest leaf width and tiller per plant were all higher than CK.The leaf age of Suihenongke rice shoots growth promoter was basically the same as that of Jinmihai rice shoots growth promoter,the stem base width,the longest leaf width and the tiller per plant were all lower than that of Ligunli rice shoots growth promoter and Hemeijia rice shoots growth promoter.The longest leaf length,root number,ground fresh weight of 100 plants and ground dry weight of 100 plants were all higher than those of CK.However,the Rice Bed Soil Conditioning Preparation were shorter than those of the other 4 treatments,the plant height did not reach the standard of strengthening seedlings,and the first leaf sheath was also shorter,indicating that this rice bed soil conditioning preparation had dwarf inhibition effect
