Satisfactory effect was achieved by applying calcium magnesium phosphate(200g/
hole )before planting the seedling of Alnus cremastogyne. When 2-year- old, Alnus plantation's
mean height,mean diameter at foot,mean stand volume and mean biomass are13%～
65%,7.6%～37.5%,63%～281%,61%～260%higher than those of the controlrespectively. The
mean biomass of above-ground is 61%～260%more ,but the biomass ofthe under-ground part
is only raised a little bit.So applying phosphate for plantling A.cre-mastogyne is an effective
methods to improve its growth and productivity.
