Pear has many effects such as moistening the lungs and cooling the heart, reducing inflammation and reducing fire, detoxifying sores, sobering up and diuresis.

1. Clearing away heat and eliminating fire: It tastes bitter, can clear away heart and purge fire, clear away heat and eliminate troubles, and can eliminate heat toxins in the blood. Suitable for people who are prone to getting angry.

2. Moisten the lungs: nourish yin and moisturize the lungs, remove dryness and heat in the lungs. Make people breathe smoothly and comfortably.

3. Detoxification: Clean up long-term accumulation of toxins in the body and improve physical health.

4. Hangover: It can relieve symptoms such as headache, swelling, flushing and other symptoms after hangover.

5. Diuresis and swelling reduction: It can remove toxins and excess water from the body, promote blood and water metabolism, have diuretic and swelling reduction effects. 1. Shaping: For shaping, we adopt a double-layered trunk shape. The tree height is controlled at about 4 meters. There are 5 main branches left in the whole tree, 3 on the first layer, 1 of which extends forward and the other 2 diagonally. Extend vertically, not vertically between lines. There are 2 main branches on the second layer, preferably opposite, and they are required to extend vertically between the rows and be arranged in the gaps with the main branches on the lower layer to make way for the light path of the lower layer. The distance between layers is 1-1.2 meters. Leave 2-3 side branches per main branch in the lower layer, and leave 1-2 side branches per main branch in the upper layer. The appropriate distance between the first side branch and the main trunk is 40cm, the distance between side branches is about 40cm, the angle of the main branch is 60-70 degrees, the waist angle is 50-60 degrees, and the angle between the side branches and the main branch is about 50 degrees.

2. Pruning: Pear has strong branching ability but weak branching ability. Most of them are short-fruited trees. When pruning, the following matters should be paid attention to:

(1) Fruiting branch group Cultivation and pruning: A reasonable arrangement of the number of fruiting branch groups is the key to obtaining high and stable yields. For varieties that are easy to bloom, the method of cutting first and then placing or cutting and retracting can be used. For varieties that are difficult to bloom, you can First grow and then retract to cultivate the fruiting branch group. For trees in the early fruiting stage and entering the fruiting stage, the fruiting branch groups should be carefully pruned. Preparatory techniques should be retained in the same branch group, rotated and updated, alternate fruiting, and control the outward movement of the fruiting part. It is necessary to make full use of light pruning and long-opening and short pruning and retraction to regulate and control the renewal, strengthening and growth results within and between branch groups, so that the period can maintain strong fruiting ability and have appropriate vegetative growth.

(2) Pruning of auxiliary techniques: Due to the weak branching power of pear trees, when pruning, it is necessary to leave more auxiliary branches in the gaps between the backbone branches to enhance the vigor of the tree. , using the results. When it affects the growth of main branches, it should be retracted in time until it is thinned out.

(3) Prevent the fruiting parts from moving outward: You can thin out the upper and peripheral strong branches to reduce the number of upper and peripheral branches, thin out the upright strong branches, leave the weak branches and release them slowly, so that It flowers and bears fruits to weaken its growth potential. Leave more and less sparse weak branches in the lower part and inner cavity, and cut them short appropriately to promote branching and rejuvenation. Retract weak branches to strong branches and buds to enhance the tree vigor. The branches extending between the rows should be retracted appropriately to maintain an aisle of about 0.5 meters between the rows.

(4) During the fruiting period, winter pruning should be intensified to rejuvenate and rejuvenate the weak inner lining, so that the inner lining and lower branches are full and full, and then rotate and replace the fruit. At the same time, prevent the fruiting part from moving outward, and maintain the growth of the tree. body structure. Summer pruning is used as auxiliary pruning, mainly using techniques such as topping, twisting, and pulling branches to promote flower bud differentiation. 1. Measures to improve fruit quality:

(1) Flower and fruit thinning: Generally adopted after entering the fruiting period.

① Flower thinning: Flower thinning should be performed on plants with too many flowers, which can improve the quality of flowers and thereby increase the fruit setting rate. The appropriate time for flower thinning is from when the inflorescence extends to the first bloom. However, in areas affected by late frost, it is safer to thin the fruits after the flowers fade. The amount of flower thinning depends on the tree vigor, variety, fertilizer, water and pollination conditions. For strong trees, sparse and leave more branches. For weak trees, sparse and leave more and weak branches. Thinning out dense and weak inflorescences first, thinning out the central flowers and retaining the side flowers.

②Fruit thinning: Fruit thinning can increase the weight of single fruit and improve fruit quality. It is usually carried out after the climax of early fruit drop, and it is advisable to carry out it about two weeks after flower drop. Just leave 1-2 fruits per inflorescence. First, remove diseased and deformed fruits, and keep the fruits with correct shape and good orientation.

③Chemical thinning: At the end of flowering, when it is expected to achieve a high yield, it is combined with pest control. You can spray 0.5% Bordeaux mixture and Baume 0.3 degree lime sulfur mixture, or 40PPM sodium naphthalene acetate (note : For safety reasons, it is best not to use chemical agents to thin flowers and fruits).

(2) Increase the application of phosphorus and potassium fertilizers.

(3) Spray 0.3% urea plus 0.2% potassium dihydrogen phosphate.

2. Measures to prevent cracked fruit, rusty fruit and pre-harvest fruit drop:

(1) Apply sufficient phosphorus and potassium fertilizers in early and mid-May, and cover the tree disk with weeds. Drought resistance and moisture conservation can prevent fruit cracking.

(2) Spray 50PPMGA3 (920) once a month or spray 10-100PPM caiacetic acid

(3) Do not apply too much quick-acting nitrogen fertilizer at one time. The pulp and peel are well-balanced to reduce rust spots caused by cuticle cracks on the fruit's epidermis. At the same time, spray less Bordeaux liquid to reduce the occurrence of rust fruit and strengthen the prevention and control of pear rust.

3. Fruit bagging: Depending on the size of the fruit, it is better to use domestic double-layer or single-layer medicated paper bags. Before fruit spots are formed on the fruit surface in mid-May, spray broad-spectrum fungicides and insecticides on the fruit surface, and then bag them in time. For double-layer paper bags, remove the outer paper bag one month before fruit harvesting to facilitate light sensitivity of the fruit. Single layer paper bag, bag when picking fruit.
