Abstract
With 4 levels of sand grain diameter and 3 levels of NPK nutrients,their effects on rooting rate,root activity,chlorophyll content and soluble sugar content of Acacia mangium photoautotrophic seedlings were studied.The result showed the 4 indexes were optimal under the condition of 0.5-1.0 mm sand matrix.Single change of the nutrient N,P or K was not good for the growth of the seedlings,but nutrients of N,P and K did have significant effect on the seedlings,respectively.
