| Abstract: | Objective Exploring the effects of different fertilizer applications on the soil fertility and fruit quality of pear orchard so as to provide reference for fertilizing soil, promoting fruit growth, improving fruit quality and economic benefits of orchard production. Method Through using the 6-year-old P. brestschneideri in Beijing sub-center as experimental material, and setting 7 sets of fertilization treatments, including no fertilizer, 100% chemical fertilizer, 25% organic fertilizer + 75% chemical fertilizer, 50% organic fertilizer + 50% chemical fertilizer, 75% organic fertilizer + 25% chemical fertilizer, 100% organic fertilizer and mineral fulvic acid. The soil properties, soil humus fractions and main fruit quality of P.brestschneideri , including soluble sugar, soluble solids, vitamin C and single fruit weight were determined. Result Different fertilization treatments could improve the soil fertility and quality of pear fruit to varying degrees. The nutrient contents and soil pH value under the 50% organic fertilizer + 50% chemical fertilizer application were improved. The mineral fulvic acid potassium could significantly increase the content of soil AK by 2.3 times compared with no fertilizer treatment. The application of 50% organic fertilizer + 50% chemical fertilizer had the most significant effect on soluble sugar, soluble solid, sugar-acid ratio and single fruit weight of P.brestschneideri. Conclusion The application of 50% organic fertilizer + 50% chemical fertilizer has the best effect on improving soil fertility and fruit quality, and therefore it is most conducive to the improvement of the economic interests of pear orchard. |
