Abstract:: Taking 18-year-old ‘Lanzhou Dajiexing’ as material,effect of two kinds of growing grass in apricot orchard(growing grass and non-growing) on ground temperature,soil moisture,physical and chemical properties comparatively were studied,and occurrence of main disease in apricot orchard were investigated,meanwhile the fruit quality and yield were determined at fruit maturing period.The results showed that temperature showed little change range with growing grass in apricot orchards of high altitude with cool or cold conditions compared to non-grass(CK),temperature showed slowly increasing and slowly decreasing,teperature of surface soil showed little change range compared to CK；fruit quality in the apricot orchards with growing grass had been improved remarkably.The soluble solid content of apricot fruit increased by 0.7 percentage point,and the average fruit weight increased by 11.8 g of the main cultivar ‘Lanzhou Dajiexing’.Furthermore,growing grass could reduce the occurrence of pests and diseases,and increase the content of organic matter in soil,improve soil fertility and water holding capacity.
