Effects of Different Fertilization Methods on Growth and Fruit Quality of 'Aiganshui' Pear Tree

The choice of fertilization method was very important for improving fertilizer utilization and reducing the loss of fertilizer in pear production applications. The experiment material was 'Aiganshui' pear tree. In this experiment, the pear cultivar' Aigan Water'was used as a test material. Three treatments were set up in the trial, such as the application of ordinary compound fertilizers, ordinary slow-release fertilizers and bag-controlled slow release fertilizers. Each process sets 4 repetitions. The results show that there was no significant effect of bag-controlled slow-release fertilizer on the morphological index of fruit quality. However, slow-release fertilizers in intrinsic quality increase the Vc content of fruits compared to ordinary compound fertilizers. And slow-release fertilizers increase the soluble solids content and the nutritional value of the fruit. The ratio of sugar to acid in the bag-controlled slowrelease fertilizer was significantly increased, the flavor of the fruit was improved, the taste was better, and the cost of fertilizer for the 'Aiganshui'pear tree was decreased.
