In recent years, fruit merchants have bought hard-to-read pears. Therefore, how to increase the fruit is the key to early pear cultivation. The author summarizes a set of methods through his practice of growing early-maturing pears. First, to improve the traditional tree-shaped high density cultivation of pear orchard, the majority of the use of inverted herringbone or trunk double fun-shape, is suitable for use on yam pear. However, due to the early-maturing series of varieties, the branching rate is low, and the results are mainly short-fruiting branches. There are few axillary shoots in fruit orchards, and there is no canopy closure problem. The park uses a central dry multi-branch shaping technique for early-maturing pears. The branch with a 3-meter spacing remains at 12 or more, and the branch height is 1.6-1.8 meters; the 4-meter-row tree height is about 2.8 meters, and the large branches are left over 15 or more. Due to the large number of large branches and single fruit spacing of 25 to 30 centimeters, the number of fruit needed is still sufficient. The single branch is lightly loaded, and the single fruit grows rapidly. The successive years of flowering also overcome the phenomena of size and year. 2. In the early spring, the surface covered with plastic film is selected according to different row spacings. The plastic film is 10.7 to 1 meter wide. It is coated on both sides of the tree along the straight line, and the middle of the road is used to keep the ground temperature. To improve the ground temperature in early spring, it can maintain water and fertilize and stabilize the soil environment. Big fruit has a very obvious role. The investment of 12 to 15 yuan per mu of plastic film is also very economical. Third, early sparse blossoms and rare fruit blossoms have a lot of nutrient waste on the tree. Therefore, the sparse flower must be carried out as soon as possible, and the buds should be sparse from the fruit when the buds begin to appear, and the two buds should be left with two flowers in each order, and no flowers should be left, so as to prevent the fruit from expanding rapidly and turning over the pears. Drop the fruit. Young fruit with small head and big head set fruit, spacing 25 to 30 centimeters. For trees over 5 years old, about 120 fruits are left, and fruit weight is above 200 grams. Each plant has a load of about 25 kilograms, and the yield per year is stable at 2500-3000 kilograms. Fourth, timely control of the upper branch of the tree on the back is strong, after the branch is flattened, the upper leg tends to stand upright. If these branches are not dealt with in time, the whole tree forces will move upwards, compete with the fruit for nutrients and affect the fruit enlargement; In addition, it wastes nutrition. Should leave 3 to 5 leaves in due course, repeatedly picking the heart 2 to 3 times, both to control their length, but also increased the effective amount of leaves, the effect of increasing fruit is very prominent. After this treatment, one or two flower buds are often formed at the first topping point, increasing the number of results in the next year. 5. Zhuang branch ring cutting promote fruit expansion in the end of May, early June on the strong branch of the tree at the base of the circumcision 1 to 2 Road, double-loop cut spacing should be 10 cm, blocking the root of nutritional reflux, promote fruit enlargement, the effect Very significant.
