Effect of Fertilizer Application on Root Biomass in Pinus elliottii
In order to investigate the effect of soil resource availability on root biomass and distribution,the 11-year Pinus elliottii plantation was used to analyze the change of wetland pine root biomass by applying nitrogen and phosphorus treatment.The results show that the nitrogen+phosphate fertilizer will increase the soil root biomass of the wetland pine plantation at 30 to 100 cm,the total root biomass of the soil surface increased by 23％to 35％and 21％to 48％in the soil subsurface than the distance of the soil surface than the root biomass of the forest,the total root length,total root projec-tion area and total root surface area.Therefore,the application of nitrogen fertilizer+phosphate fertilizer can increase the root biomass of wetland pine plantation,and promote the effectiveness of soil resources.
