Summer pruning is performed during the growing season. It mainly suppresses the growth of new shoots by pruning, removes dense branches, overlapped branches, competition branches, improves ventilation and light transmission conditions, increases photosynthesis, accumulates nutrients, increases yield and quality, and achieves high yields and stable yields. First, pruning time from the beginning of spring growth until the end of picking pepper. Second, the pruning method generally adopts methods such as opening the angle, wiping the bud, removing the sprouting, picking up the heart, twisting the tip, injuring, girdling, and the like. Third, different ages of plastic pruning 1, young trees pruning: Take two kinds of high yield tree. (1) Multi-branched plexiform shape: The stem height is 10-15 cm, which promotes 3-5 main branches with different directions and uniform growth. In the second year, each main branch was cut to 50-60 cm and promoted to form the first lateral branch, which in turn was cultured to form the second and third lateral branches. It should be noted that the same side branch is in the same direction, and the first and second side branches are in opposite directions. Branches should be cultured on the main lateral branches. (2) naturally happy to set a height of 30-40 cm. In the same year, more than three branches will be promoted. These branches will reach 30-40 cm in height in the middle and early June. The three main branches will be set again to pick up the hearts and cultivate the side branches. The rest of the shoots will be picked up. Take pull, drop, etc., to control growth, as a subsidiary support. 2. The pruning of prickly-ash trees in the early fruit period is generally 3-5 years. The tree age is in the early fruit period; (1) Over-exposure, upright branches may be pulled, draped, or cut. (2) Sparse branches to adjust light and nutrition. (3) It is desirable to fold and shape branches to stay one. 3. Pruning of fruit trees (1) The proportion of large, medium, and small fruiting branches must be maintained at 1:3:10. (2) Topping up many vegetative shoots and leggy branches to reduce nutrient consumption and promote fruit growth. (3) For vegetative growth and fruitless trees, carry out girdling to inhibit vegetative growth and promote flower bud differentiation. (4) For the main branch with a small base angle, pull and drop are used to promote the result. 4. The trees that have been pruned for more than 25 years in the aging tree will enter the aging period. Specific use of "four sparse" and "four guarantees", that is, thinning weak branches, retaining strong branches; drooping drooping branches, retaining slanting branches on the back; sparse stems and branches of dead pests, retaining robust branches; sparsely retracting aging branches Keep fresh branches.
