Effect of Different Sowing Depth on Seedling Emergence of Scutellaria baicalensis Georgi

摘要(Abstract):

[Objective] To explore effect of different sowing depth on seedling emergence of Scutellaria baicalensis Georgi,so as to provide a basis for ensuring a good cultivation in large scale.[Method] 7 treatment groups were employed in this study,sowing depths of which were 0,0.5,1,1.5,2.0,2.5 and 3.0 cm,respectively.Randomized block design with three replications was adopted in this study.[Results] Emergence rate of Scutellaria baicalensis Georgi in groups with sowing depth at 0(0 cm soil coverage)and 0.5 cm(0.5 cm soil coverage)was higher than that in other groups,and they were up to 69% and 60% respectively.Followed by groups with sowing depth at 1 and 1.5 cm,their emergence rates were 46% and 16%.The others were less than 5%.[Conclusion] Along with the increase in sowing depth,the emergence rate of Scutellaria baicalensis Georgi decreased,in other words,the shallower the sowing depth was,the higher emergency rate would be and its speed would be faster.Therefore,the most appropriate sowing depth for Scutellaria baicalensis Georgi in large field was 0 or 0.5 cm.
