Abstract Laiwu ginger was used to investigate the effect of soil bulk density on the growth,yield and quality of ginger .Three treatments,1.49(CK),1.36(T1) and 1.20(T2)g·cm~ -3 were set in the experiment.The results indicated that the soil of low bulk density,could obviously promote the growth of ginger,and improve yield.The plant height,stem diameter ,branch and leaf number of T2 were higher than CK by 17.9 %,14.0 %,35.2 % and 36.1 % respectively.The fresh weight of root,stem,leaf and rhizome were higher by 43.3 %,...
