First, pull branches to promote fruit. Pulling branches can make young trees form canopies early, prompting early shoots and multiple shoots of pear trees, inhibiting vegetative growth of trees, and turning into reproductive growth as soon as possible, eventually reaching the goal of early end of high yield. After the pears have fallen to the end of the autumn, the branches can be pulled before the second spring sprouts. Pull branch method is: 1 pair of annual trees. For the annual saplings that were planted in the same year, leave the tree tip at a distance of 40-50 cm from the ground surface. The degree of pull and bend should reach the level or 80 degrees. After the second year of putting the rope, the natural curvature of the tree's tip should be maintained at about 90 to 100 degrees. 2 pairs of trees. After the first year of branching, many shoots were promoted. In the second year of pulling branches, in the first year of pulling the branches, select a strong point from the base and keep 40 centimeters upward to pull in the opposite direction, and pull the other branches to the right and left. 3 to more than three years of tree management. In the second year of bending, select a strong branch from the base to stay 30 to 40 centimeters to the second year of pulling the branches in the opposite direction to pull and bend the other branch to the left and right, so that the formation of 3 layers, 3 to 5 Crown of the main branch, the height of the tree is generally controlled at about 2.5 meters. For a tree with more than three years, the dense branches, stem branches, and stems and branches of stems at the main stem and main branches should be cut first. For other upright vegetative branches, branches, twigs, and branches are still handled to promote the early fruiting of the trees. In order to control the growth of the crown, the tree is pressed by the fruit. Second, hanging branches crack. The pear branches are soft and the branches will droop when the fruit is abundant. In the case of excessive results, it is easy to split, and it can be tied to the stem in the middle of the stem. The result of the pear tree is suspended from the tendon by a rope to prevent cracking. A long stem with a fork can also be used to hold the pear branch in the middle to prevent lychee from being overweight. Third, fertilizer management. After the fruit is harvested, the basal fertilizer is applied in time, and 50 to 100 kg of organic fertilizer per plant, 0.3 to 0.5 kg of potassium sulfate, 1 to 1.6 kg of superphosphate, 0.3 to 0.6 kg of ammonium nitrate, and a depth of 25 to 35 cm for fertilization. Watering in time after fertilization; low-lying and easy-to-sink pear garden should pay attention to drainage. Before the soil is frozen after defoliation, the entire garden is filled with winter water to facilitate the safe wintering of trees. Fourth, scrape old skin. The function of pear tree scraping old skin is mainly to remove overwintering pest parasites. Common scrapers and other available tools are usually used. For the pear trees with a skin age of more than 10 years, the major branches and dry skin layers will have different degrees of cracks. Therefore, scraping should be carried out. When scraping the skin, it is necessary to scrape it from the top to the bottom so that the operation is appropriate. At the same time, care must be taken not to injure the phloem. In order to protect the trunk and reduce pests and continue parasitic damage, after scraping the skin, the dander should be collected and burned in time. The main branch should be promptly treated with lime 10 kg, salt 2 kg, sulfur powder 1 kg, animal or vegetable oil 0.1 kg, water 20 The whitening agent formulated in kilograms is whitened, and Bordeaux's liquid is sprayed in full to better exert the effect of scraping. Fifth, clearing the garden. After defoliating the pears, they must timely clear the fallen orchards, remove the dead branches, remove the stale fruits, remove the weeds around the orchard, and burn them together. For hanging ropes and top branches should be burned in time after use. The deep turning of pear orchards is usually done from autumn until the soil is frozen. Do not hurt the roots. The exposed roots are buried with soil at any time. Deep plowing is best combined with fertilization, the depth of more than 30 cm, in order to ripen the soil and promote root growth; when turning over the topsoil and the heart and soil should be placed, when the backfill, the fertilizer and the topsoil are mixed and filled below, the heart and soil fill in the upper layer. The main roots and thick lateral roots encountered during deep plowing can be cut at the periphery of the canopy and the roots can be cut with a pruning shear. Other thicker root systems can be shorn and cut with a pruning shear, which can promote massive root extraction. After the deep plowing, it should be watered in time. The deep turning of the pear orchard can be carried out by deep-turning between rows and then deep-sweeping the plants. Six, prevention and treatment of diseases. In the years from late August to early September, special attention should be paid to the prevention and treatment of pear scab, with 1:2 (200-240) Bordeaux fluid as the main prevention, which can effectively control the occurrence of diseases. If 15 or 20 days, 50% of carbendazim wettable powder 500 to 600 times or 70% thiophanate-methyl 800 times is sprayed on the pear orchard, which is harmful to ringworm, scab, and mold, to control the condition. Seven, pest control. In the autumn, if insect pests such as aphids, red spiders, Pterospira pulcherrims, Pyrosphaeridae, and peach borer pests occur, they should be sprayed once every 15 days for about 2500 to 3500 times for 10% of imidacloprid, or 1000 kg for Pyrimax. Doubling, or 40% of dicofol 700 to 900 times control.
