Study on the Effects of Water Depth on Seedling Growth in Rice

Difference in tiller and root growth of hybrid rice Liangyoupeijiu with different water depth at seedling stage was studied.The result showed that tiller and root growth were closely correlation with the water level.The deeper level of water was,the tiller and root growth were poorer.The low level water can increase tiller and root growth,and improve the quality of rice seedling.However,when the water depth maintained 4 cm,the tiller,root growth and root-shoot ratio were inferior.Effective water manage measure at seedling stage was discussed in rice production.
