Abstract
In order to increase the fruit yield and economic benefit, pesticides and fertilizers are overused in Chinese orchards, which leads to a series of environmental problem and food safety issues like water body pollution, organic content decrease. The effect and influence of various organic compost mulching on orchard soil property are discussed here, to improve soil ecological structure, utilize and circulate wastes resource rationally and increase the reservoir storage of orchard. The results showed that the mulching of the organic compost can decrease the surface soil bulk density apparently, loosen the soil and optimize its air permeability. Meanwhile, it can increase the nutrient elements in the soil, improve soil property and thus to boost the grow of the tree fruit and root as well as to improve the physical, chemical and biological property of soil. Along with the ever-increasing length of the compost substrate mulching, the organic content of the soil has been increased apparently, and the orchard soil property has been improved obviously, which has eased a series of environmental issues, increased the crop yield and improved the crop quality at the same time. It has increased the economic efficiency to some extent.
