After the pears are harvested, their root growth is still at the peak of a half-month, which is the key moment for pears to accumulate nutrients. Management here is directly related to the pear fruit yield and quality in the next year.
First, scientific fertilization. For pear trees aged 6 to 10 years, 100 to 150 kg of organic fertilizer is applied to each plant. After 10 years or more, 100 to 200 kg of organic fertilizer is applied to each tree, and a small amount of compound fertilizer or available nitrogen fertilizer is added. After the fruit is harvested, the leaves of the pear tree still have a growth period of about 50 days. Spraying 0.3% potassium dihydrogen phosphate plus 0.1% urea solution (spray once every two months) on the foliage can increase the nutrient accumulation of the tree.
Second, a reasonable pruning While fertilizing the pear tree, it is appropriate to prune the pear tree branches and trim the branches and branches, leaving the branches thin and thin. For dense branches, thin branches, branches and branches, dead branches, etc., they should be cut off and taken out of the garden. At the same time, topping the late autumn shoots, promoting its lignification, so as not to be affected by freezing injury. III. Prevention and control of diseases and pests The main diseases and pests that harm the pear trees include pear black spot disease, pear black spot disease, and pear borer pests. The disease can be controlled by 20% dexamethasone water 5000 times solution or 50% carbendazim wettable powder 800 times solution; Pestivorous insects can use 50% phoxim emulsion 1000 times or 2.5% bromithrol emulsion 3000 times solution Prevention. After deciduous pear trees, it is necessary to clean the fallen leaves and remove dead leaves and weeds. This will eliminate many pathogenic bacteria and pests that are overwintering, and reduce the source of diseases and pests in the coming year.
IV. Deep-turning and soil-deepening soils can enrich soil organic matter, which is generally carried out in autumn and winter. It uses intercalation deep turning and has a depth of 35-40 cm. While deep-sweeping, it can also combine with basal fertilizer, which can increase soil oxygen and improve soil structure.
5. After applying green manure to deep-turning and improving soil, apply green manure in the pear orchard. Green manure contains a large number of elements such as nitrogen, phosphorus, and potassium, as well as various trace elements such as calcium, magnesium, copper, zinc, and boron, and is a full-price fertilizer. The application of green manure is not prone to deficiency of nutrients, which can reduce abnormal physiological phenomena such as poor stress resistance and poor growth due to malnutrition and lack of trace elements.
