摘　　要：为明确新型种衣剂晓光春蕾在寒地水稻苗床上的应用前景与价值,明确最佳用量,采用完全随机试验设计,于2020年在黑龙江省农业科学院佳木斯分院育秧大棚进行,设置6个处理,调查出苗率、发病率及秧苗素质各项指标。结果表明:晓光春蕾种衣剂16 mL包衣4 kg处理出苗较早,出苗率较高,发病率为零,且在株高、根数、百株地下干重、茎基宽和充实度等方面均优于其他处理,有利于形成壮苗,是寒地水稻床应用的最佳用量。In order to clarify the application prospect and value of new seed coating agent Xiaoguangchunlei on the rice seedbed in cold area,the best dosage was determined and the design was completed by random experiment.In 2020,6 treatments were conducted in the seedling raising shed of Jiamusi Branch of Heilongjiang Academy of Agricultural Sciences.Emergence rate,incidence rate and seedling quality index were investigated.The results showed that the seedling emergence time of Xiaoguangchunlei seed coating agent 16 mL coated 4 kg was eralier,and the emergence rate was higher,the incidence rate was zero,and it was better than other treatments in plant height,root number,underground dry weight of 100 plants,stem base width and plumpness,which was conducive to the formation of strong seedlings and was the best dosage of rice seedbed in cold region.
