What is the main role of fruit tree summer scissors?
Summer pruning is also called growth pruning, and summer pruning is the continuation and supplement of winter pruning. Because summer cuts are carried out every year from June to August, the fruit trees grow vigorously. If they are not managed in time, they will cause tree branches to become closed, interfere with the tree type, and consume tree branches, disturb the tree type, and consume a lot of trees. Nutrition. Such as the use of summer shear in time on the dense branches, the amount of long branches to carry out the iii?éˆé€– 郑 ? è°–æ¦·ã„Šé‡ è°–æ¦·ã„Šé‡ è°–æ¦·ã„Šé‡ è°–æ¦·ã„Šé‡ è°–æ¦·ã„Šé‡ è°–æ¦·ã„Šé‡ è°–æ¦·ã„Šé‡ è°–æ¦·ã„Šé‡ è°–æ¦·ã„Šé‡ è°–æ¦·ã„Šé‡ è°–æ¦·ã„Šé‡ å²£å– å²£å– å²£å– å²£å– å²£å– å²£å– å²£å– å²£å– å²£å– æµš 浚 浚 浚 浚 浚 浚 浚 浚 浚 浚 浚 浚 浚 黾 黾 黾 黾 黾 黾 黾 黾 é” é” é”倜 㕠㕠㕠鸬 鸬 鸬 ? ? ? ? ? ? ? ? ? ? ? 艋 艋 艋 艋 艋 艋 å²· å²· å²· å²· å²· å²· å²· ã³è™¢å³ ã³è™¢å³ ã³è™¢å³ ã³è™¢å³ ã³è™¢å³ ã³è™¢å³ ã³è™¢å³ ã³è™¢å³The Chinese name for the Chinese name is “Chinese 笮∧攴痛笮∧攴†and â€œæ‰ æ‰â€. å‹Ÿ æ‰ æ‰ è—œ è—œ 踔 踔 踔 踔 踔 踔 踔 踔 踔 踔 踔 踔 å—³ å—³ å—³ å—³ å—³ å—³ å—³ å—³ å—³ 藜粑 藜粑 藜粑 藜粑 藜粑 藜粑 藜粑 藜粑 藜粑What are the principles and requirements before the war? 1. Summer should be carried out on time. The results of advance or miss are not ideal. 2. The amount of pruning should be light, because the branches must be removed in summer, and many weakened. If the shear volume is too large, the heat will damage the tree, weaken the tree potential and affect the flowering results. Therefore, the amount of shear should be appropriate. 3, according to the provisions of pruning, such as the pull branch angle, twisting the tip of the site, the method, the width of the ring cut, etc., must be strictly in accordance with regulations. What are the methods of Xia Jianchang? Summer cutting methods are: wipe buds, carved buds, in addition to sprouting, circumcision, topping, tipping, taking branches, thinning branches, retraction, picking leaves, other branches, circle branches and so on. Topping: In the growing period, the point of growth at the tip of the shoot is called topping. It can inhibit the growth of new shoots, promote the germination of lateral buds, increase branching, and accelerate the expansion of the crown, which is conducive to early results. Topping the result tree can adjust the growth potential, promote flower bud differentiation, and can promote the development of branches and leggy branches into fruiting branches. According to shoots, shoots growing at the base of the shoots or the upper part of the shoots are prone to sagging during the growth period, but the shoots are not twisted. Twisting tips can impede nutrient transport, weaken the tree potential, and help form flower buds and resultant branches. Take the branch: During the growing period, the new shoot is bent from the base to the top, so that the phloem and the xylem are slightly separated and injured. Take the branch to the sound, but do not break the branch. Taking a branch can weaken the apical dominance, promote the secondary branch of the middle and lower part of the shoot, and help the flower bud differentiation to increase the number of short branches. It should be appropriate to take the sticks before and after noon. Ring-cutting: For the base of branches that develop vigorously without flowering, cut twice with a circumcision or knife ring. The width is based on the principle of timely healing in the year, approximately 1/8 or 1/10 of the diameter of the trunk, and the depth of the trunk is very good. unit. In doing so, the organic nutrients in the upper part of the plant can not be transported downwards for the time being, so that the vegetative growth can be transformed into reproductive growth to form flower buds and the fruit setting rate can be improved. In addition to sprouting and thinning: Thinning is to eliminate dense new branches. Through de-emergence and thinning, nutrient consumption can be reduced, light conditions can be improved, selection can be improved and quality can be improved.
