Based on agroforestry systems under camphor trees , we compared the growth dynamics of bush ivy under different light environment , to explore the possibility of breeding bush ivy under trees and provide a scientific basis for increasing the rate of land use .
Governments at the appropriate level , with the support of the relevant international and regional organizations , should help farming household communities to investigate and promote site-specific technologies and farming systems that conserve and rehabilitate land , while increasing agricultural production , including conservation tillage agroforestry , terracing and mixed cropping .
The results show that in comparison with the farmland system , the agroforestry systems have the accumulative effect of biomass , energy , nutrient elements and value , and larger productive potential . Also the economic benefit and the utilization rate of auxiliary energy , solar energy and nutrient elements in the agroforestry systems are higher .
