First, pulling branches to promote fruit pear trees fall after the end of the leaf to the second year before the spring budding can be carried out. The branching method is: the annual saplings that were planted in the year, and the tree tip is bent from the ground surface at a distance of 40-50 cm. The degree of pulling and bending should reach the level or 80 degrees. After the second year of putting the rope, the natural curvature of the tree tip should be maintained at about 90-100 degrees. For the two-year-old tree, the first year after pulling the branches will trigger a lot of shoots. In the second year of pulling branches, in the first year of pulling branches, select a strong branch from the base to stay 40 centimeters upward to pull in the opposite direction, and pull the other branches to the right and left. For the three-year-old tree, in the second year of the bud bending, select a strong branch from the base and leave 30-40 cm upwards to pull the opposite direction of the second year, and bend the other branches to the right and left. Layers, crowns of 3-5 main branches, 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 and trunks should be cut off first. For other upright vegetative branches, branches, branches, and branches must be treated to promote early fruiting and yielding. .

Second, hanging branches cracking pear branches soft, fruitful results in a large fruit period, the branches will droop. 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 and water management in the timely use of basal fertilizer after fruit-picking, according to the tree size per plant 50-100 kg of organic fertilizer, potassium sulfate 0.3-0.5 kg, 1-1.6 kg of superphosphate, ammonium nitrate 0.3-0.6 kg, fertilization depth 25-35 cm. Water timely after fertilization. Low-lying and easy-to-sink pear gardens should pay attention to drainage. Before the soil was frozen after defoliation, the entire garden was filled with winter water.

Fourth, scrape the old skin to more than 10 years old pear trees to be scraped. When scraping the skin, it must be scraped from the top to the bottom for operation, and 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 used 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 was brushed white, and Bordeaux's solution was fully sprayed to better achieve the effect of scraping the skin.

5. After clearing the garden and plowing the fallen leaves of pears, it is necessary to timely clear the fallen leaves of the orchard, remove the dead branches, remove the stale fruits, eradicate the weeds around the orchard, and burn them centrally. 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 at a depth of more than 30 cm to ripen the soil and promote root growth. When the soil is turned, the topsoil and the soil and soil are to be separated. When the landfill is backfilled, the fertilizer is mixed with the topsoil, and the soil is filled in the top 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.

6. Disease Prevention and Control In the years of heavy rain 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 15-20 days, 50% carbendazim WP 500-600 times or 70% thiophanate-methyl 800 times is sprayed on the pear orchard, which is harmful to ringworm, scab, and mold, you can control the condition of the disease. .

VII. Insect Pest Control In the autumn, if pests such as aphids, red spiders, pear caterpillars, pear borer pests, and peach borer pests are harmed, 10% imidacloprid 2500-3500 times or pear locust extract should be sprayed once every 15 days or so. 1000 times or 40% dicofol 700-900 times liquid control.
