The nutrient status of soil and leaf status in the main jackfruit plantations in Yunnan province was studied to provide basis for rational fertilization of jackfruit plantations. The soil nutrient status and leaf nutrient contents in different soil layers (0 ~ 20，20 ~ 40，40 ~ 60 cm) of 15 representative plantations in Yunnan province were investigated and analyzed. The results of soil nutrient contents were compared with the soil nutrient classification standard，and the correlations between them were analyzed. The results showed that :(1) The soil nutrient content was the most abundant in 0 ~ 20 cm soil layer. Except for soil pH and available boron，the contents of organic matter and other nutrient elements in different soil layers had a large range and coefficient of variation. (2) 86.67% of the soil pH values were less than 6.5，and the soil was acidic. The contents of organic matter，total nitrogen，total potassium，alkali hydrolyzable nitrogen，available potassium and various medium and trace elements were above the middle level. The contents of phosphate in different plantations were at varying levels，and the difference was obvious. (3) There was a very significant positive correlation between soil organic matter and soil total nitrogen；Soil total phosphorus was positively correlated with soil available potassium，available zinc and exchangeable calcium，and positively correlated with available phosphorus and available manganese；Soil pH was positively correlated with soil exchangeable magnesium，and negatively correlated with leaf nitrogen，leaf manganese，leaf zinc and leaf copper；There was a significant positive correlation between leaf calcium and soil exchangeable calcium. Therefore，for the fertilization of jackfruit plantations in Yunnan province，it is suggested that lime or soil conditioner can be applied to increase soil pH，and the application of organic fertilizer，phosphorus and boron fertilizers can be increased，and the application of nitrogen，potassium，calcium，magnesium，iron，manganese，copper and zinc fertilizers can be appropriately controlled，so as to achieve balanced fertilization.
