Topic:different ratio of mixed plantations of Eucalyptus grandis + toon evaluation of soil and water conservation benefits
Abstract:Sichuan hilly area of South Africa annual study of Eucalyptus grandis plantation,create a different ratio of mixed plantations of Eucalyptus grandis + toon runoff plots,observed the loss of soil moisture and nutrient status,observed during the runoff varied from 2.45 to 13.55L/m2,loss of the elements ranges from C:30.9 110 mg / L * m2,K:26.7 88.7mg / L * m2,Fe:31.4 70.1mg / L * m2,Ca:27 52.7 mg / L * m2,Mg:21.4 45.6mg / L * m2,Zn:13.2 31.8mg / L * m2,Mn:10.5 24.3mg / L * m2,Cu:8.4 13.6mg / L * m2,The results show that the different runoff of surface runoff volume and soil nutrient loss showed mixed ≈ 6:4 8:2 mixed
