Totally nine experimental treatments for cherry trees with different water-fertilizer amounts were established through fertigation with drip irrigation method, based on which the soil moisture and physicochemical property of cherry orchard were measured, as well as output and quality of cherry fruit under different treatments. Results showed that under different treatments, during the whole growth period of cherry trees, soil moisture content had a downward trend;during the irrigation period, the more the irrigation amount was, the higher the moisture content of shallow soil was, and it had no obvious influence on the deep soil. Water-fertilizer conditions under such experimental treatments can significantly improve the fruit quality. Higher fertilizer amount can increase fruit diameters;appropriate water amount can significantly improve the fruit hardness;higher fertilizer amount and lower water amount can reduce the content of titratable acid;lower water and fertilizer amounts can increase the soluble solid content;middle-level fertilizer amount and lower water amount can increase the crude protein content;lower water and fertilizer amounts can increase the vitamin C content of fruit, and appropriate water amount and lower fertilizer amount can increase the content of total soluble sugar. The linear relations between various indexes of soil nutrients and microelements of cherry fruit were comprehensively analyzed, and the sensitivity analysis regarding various indexes of soil nutrients and fruit quality was conducted by introducing Spearman rank correlation coefficient method. Ammonium nitrogen and nitrate nitrogen contents in soil were under instable conditions and no clear rules were found in nutrient changes;among various indexes of soil nutrients, the organic content had positive correlation with full iron content of fruit;the content of available ammonium nitrogen had positive correlation with total chlorine content;content of available nitrate nitrogen had positive correlation with contents of total calcium, zinc and chlorine of fruit;content of available phosphate had positive correlation with full iron content;content of rapidly available potassium was negatively correlated with full calcium content. Among soil nutrients, ammonium nitrogen and nitrate nitrogen had close relations with most indexes of fruit quality.
