Crop-animal mixed orchard is a kind of integrated orchard management mod, it can improve the biological productivity and agricultural ecological environment,increase farmers’incom, and it has huge potential in achieving sustainable development. Due to the high benefits, this mode wins wide popularity in farmers. As the shortage of land increasing, it makes staple practical significance. With economic development, social progress, population growth and the demanding for good quality fruits, it becomes an urgent problem that how to increase the utilization of limited land and improve fruit quality at the same time.The purpose of this research is imporve the sustainable development of massive potential in the orchard,through analysis the fruit quality, operatic soil physical and chemical properties and the economic benefits of unit area in soil clean orchard,’pear-goose (chicken)-grass’orchard and Growing grass orchard.This study is based on field investigation and laboratory analysis, by analyzing soil properties and fruit quality between clean tillage and’pear-goose-fruit’Crop-animal mixed orchards,’pear-chicken-grass’Crop-animal mixed and weeds pear ochards, the following conclusions:1.Comparing with the clean tillage orchard, the Crop-animal mixed orchard improves soil organic matter content, but weeds pear ochard even contents more soil organic matter than the Crop-animal mixed orchard. On improving the content of soil organic matter, they are sorted like this:weeds orchard>crop-animal mixed orchard>clean tillage orchard.2.About soil enzyme activities,including soi sucrase, urease, dehydrogenase and soil catalase, we found that, overall, weeds orchard>crop-animal mixed orchard>clean tillage orchard. So we advocate weed cultivated mode more.3.The main microbial in soil:Growing grass orchard>Crop-animal mixed orchard>soil clean orchard.4.In terms of improving fruit quality, crop-animal mixed and weeds orchard are nearly the same, negligible. But the crop-animal mixed orchard perfoms higher than clean tillaged orchard.5.The crop-animal mixed pattern shows much more benefits than the other two patterns. Compared to the other two patterns,the crop-animal mixed orchard is not a simple planting, it can use the limited land efficiently, mix planting and livestock breeding, therefrom creats better efficiency. Thereby increasing farmers’income.
