Abstract:
Three orchards with long-term application of different fertilizers were selected.By measuring the nutrient content of the fallen leaves and the pruning branches of different years,the total nutrients taken away from the pear trees by the fallen leaves and pruning branches each year were studied,in order to provide reference for fertilizetion of fragrant pear.The results of the study showed that the nutrient content gradually decreased as the pruning years of fragrant pear branches increased with different fertilizers.The order of nutrient content in fallen leaves and pruning branches of pear with different fertilizers was nitrogen,phosphorus,potassium,iron,manganese,zinc,and copper were 378.9,53.3,31.1,3.6,0.3,0.2,0.1 kg?hm-2.The nutrient removal amounts of chemical fertilizers were 303.5,43.6,30.0,3.0,0.4,0.3 kg?hm-2 and 0.1 kg?hm-2.The nutrient content removed by sheep manure compost was the lowest,and the removed nutrient content was 278.9,35.3,16.1,2.5,0.2,0.3 kg?hm-2 and 0.1 kg?hm-2.The input of different fertilizers has a great effect on the accumulation of nutrients in the fallen leaves and pruning branches of fragrant pears.The nutrient content removed from the fallen leaves and pruning branches of pear trees each year is also used as a basis for rational application and has positive significance in production.
