In this paper, the Loop Apple pear production base of the leaves and soil nutrition continuity research . The results show that , in poor orchard soil N , P , K , organic matter content and leaf nutrient elements (Ca elements) showed the good orchard higher than the middle orchards medium orchards than poor orchard . Good and poor orchard leaf nutrient elements , K element is the smallest element of K elements of a great influence on the nutrient levels of the tree , as well as production , quality . Blade of Ca elements of performance as poor orchard above the middle orchards, medium orchard than good orchard and blade element Ca is negatively correlated with other elements . The experimental fertilization experiment show , the reasonable soil fertilization can improve the soil nutrients and leaf nutrient levels . Full fruit period the apple pear monoclonal appropriate fertilization amount of organic fertilizer 10-20Kg, special fruit tree fertilizer 500g, flowers into disposable mixing facilities .
