Abstract:
Soil waterstable aggregate contents and chemical properties of bamboo (Phyllostachys heterocycla) and broadleaved mixed forest stands were studied in Jiangxi province. Researched stands can be divided into Type A(bamboo stands), Type B(5%~15% broadleaf trees), Type C(155%~25% broadleaf trees), Type D(25%~35% broadleaf trees) and Type E(35%~45% broadleaf trees). The results revealed that Type A had the lowest soil water-stable aggregate content, but highest soil structure destroy rate(average 37.27%), Type C had the lowest soil structure destroy rate(average 12.33%). The average contents of soil organic matter, total N, hydrolyzed N, available P, total K were highest in the soil of Type C stands, Type D had highest average contents of soil total P, available K, Type A had lowest average contents of soil total P, available K. It suggests that suitable mixed rate of bamboo and broadleaf trees is good for the maintenance of soil fertility.
