In order to make more fruitful pear fruits, improve fruit quality, and increase the yield and sweetness of pear fruits, we must start from raising the roots and cultivating roots and grasp the comprehensive management based on fertilizer and water.

First, deep basal fertilizer, cultivating root protection. There are two peaks in the root development of pear trees, one in late May to the middle of June and the second in September to November. In order to make the root system strong and healthy, we must maintain a good root protection. One can plant leguminous green manure between rows of pear orchards; secondly, it can cover rice straw, wheat straw, and other stalks and grasses around the roots to prevent loss of nutrients in water and soil, cultivate and improve soil, and better protect the root system. Send new roots. Advocate autumn and winter deep application of organic fertilizers, the best application of bio-organic compound fertilizers, such as bio-organic fertilizer compound enzyme, high-energy organic compound fertilizer.

Second, top-dressing to ensure nutrition. Before the flowering of pear trees, nitrogen-based fertilizers were mainly used; after flowering, topdressing nitrogen, phosphorus, and potassium each contained 15% of compound fertilizer 30-50 kg or three-element compound fertilizer 25% of 75 kg of compound fertilizer; During the expansion period, about 15 kilograms of urea are chased per mu, and Huimanfeng or Zhuangfuxing active liquid fertilizer is sprayed at 2 to 3 times at a concentration of 1:500.

Third, timely sparse blossoms and fruit trees to maintain the golden tree potential. As a result, the pear trees should not be prosperous. In addition to the management of fertilizer and water, they must also be repaired and the trees should be thinned. The whole branch was younger. The middle and small branch groups accounted for 90%. The middle and short branches were robust, and the new peripheral shoots were 30-40 cm long. When flowering results, it is necessary to neglect weak buds and flowers. After 30 days of flowering, the general fruit no longer falls off. At this time, the disease, fruit, malformed fruit, and fruit stagnation should be eliminated so that the output of the pear tree can maintain its average annual output.

Fourth, timely irrigation and drainage, prevent pests and diseases. During the growth of the pear tree, it is necessary to maintain the sprouting water, post-flower water, fruit water, and autumn and winter water in the soil. At the same time, a large drainage ditch should be dug around the pear orchard to prevent waterlogging. In terms of pest control, it is mainly used to prevent pear rust, black spot disease, red spider, pear hibiscus, leaf miner, pear borer and so on.
