| Abstract: | A grid-system method was used to set up the plots in Dalingshan Forestry Station to collect forest litters for the determination of total nitrogen,total phosphorus and total potassium.Seasonal variations of litter nutrients were investigated.The results showed that :(1) Among the 7 forest stands,the highest litter nutrient content of total nitrogen and total potassium was found in the Acacia mangium stand,the highest total phosphorus in the Castanopsis fissa stand,while the lowest content of NPK was found i... |
