Abstract:
The influence of volume weight of soil on maize seedlings growth was researched under condition of controlling water and fertilizers.The results indicated that the influellce of volume weight of soil on maize seedlings growth was significant.Following soil volume weight change,maize root and its aerial part all generate corresponding change.Within a cer tain extent,the relation between maize root length and volume weight of soil appeared signifi cant linear negative correlation.The volume weight of soil was larger,length of maize root was shorter, and root diameter was bigger.Meanwhile the relation between dry weight of root, tall of plant and volume weight of soil all appeared significant linear regression,which was negative correlation.The dry weight of aerial part and the top root ratio (T/R) and vol ume weight of soil was relation of guadratic function.While volume weight of soil is near1.30g/cm3,the dry weight of aerial part gets to maximum.The volume weight infuleuces also growth of maize leaves.
