The growth of eucalyptus trees is more regular and structured, and they generally form a conical shape. After that, they gradually became round-headed. However, if the plastic surgery is not carried out, the canopy is often overly dense and inconvenient to manage. The resulting location is limited to the periphery, and the flowers and fruits are prone to frost damage and sunburn. The economic output is low. Intensive (dwarf) cultivation is one of the development directions of modern fruit trees, and it is also the direction of the development of eucalyptus cultivation. In the cultivation of high-quality alfalfa, pruning, thinning (spining), fruit thinning, bagging, and single-fruit harvesting are relatively expensive. Therefore, dwarfing eucalyptus can significantly increase work efficiency and reduce costs. The tree types commonly used in production in each production area include trunk layered (evacuation layered), open-hearted, and trunk-shaped. At present, Fujian Putian and other production areas have begun to promote low-crown dwarf cultivation techniques, the tree used for the double-round head shape. (1) The double round shape is a two-layer structure with about 50-80 cm between layers. The trunk is 40-60 cm high. In the first year, after the seedlings were dried, they left 4-5 main branches, stretched on all sides, and pulled into an angle of 40-50 degrees with the trunk. In the second year, at the appropriate location, several sub-branches were selected and the backbone was truncated so that the plants no longer increased and a hollow double round head was formed. After 3-4 years, a crown can be formed. After adult closure, the canopy height is controlled at 2.5-3.0 meters for easy management. This kind of tree has a short crown and is easy to operate. Better ventilation and light transmission, higher fruit quality. As a result of vigorous growth, a large number of shoots will sprout every year in the upper part of the banyan tree. Therefore, in order to maintain the tree shape and promote the results (big fruit and high quality), it is necessary to pull and retreat the double-layered round eucalyptus every year. (2) Evacuation layered The tree generally has 3-4 layers. The main branch number of each layer is 3-2-1 or 3-2-1-1 from bottom to top, and 6-7 main branches. There are also 4-3 or 4-3-1, 7-8 main branches. In the trunk height of 30-60 cm, retain the first layer. The distance between the first layer and the second layer should be relatively large, ranging from 1 to 1.2 meters. After that, each tip is short. The main branch is equipped with 3-4 main branches, arranged in a staggered manner. The number of sub-branches of the upper main branch gradually decreases from that of the lower main branch. The main branches on each main branch should be aligned in the same direction. The first sub-branch is 40-60 cm away from the base of the main branch, and the distance between the sub-main branches gradually decreases. The main branches at all levels should also be staggered so as not to overshadow. When the main branch of the top floor is selected, the upright branch at the top of the trunk is removed, so that the tree is no longer taller. This type of tree is easy to form, its tree potential is moderate, and its yield is high. However, the number of main branches is more, and in areas with little sunshine, the ventilation and light transmission are poor, which affects the quality of the fruit. (3) The main difference between the trunk shape and the evacuation layered form is that it does not have an obvious hierarchy, and does not grow several main branches from one place. All the main branches are deployed at different heights year by year. Leave a main branch at a height of 40-60 centimeters in the main trunk, toss the rest of the shoots, level them out, and cultivate them as ancillary cultures. Overly dense ones can be wiped away. After the central trunk extends upwards, leave the second main branch 30-40 cm upwards, opposite to the first main branch. Further upwards, continue to leave the third and fourth main branches, leaving the second main branch at a distance of 30-40 cm, opposite to the first main branch. Further upwards, the third and fourth main branches are still left, the spacing is still 30-40 cm, and the orientation is between the first and second main branches. These four main branches just form a "10" shape. If you continue to equip the main branch above, it's best to be in the free space below the main branch. The whole tree has 5-7 main branches. The spacing of the main branches above is slightly shorter. Each main branch is equipped with a sub-master branch and cultivated as a branch. The tree form basically after 4-5 years of colonization. After 7-8 years, depending on the strength or weakness of the tree, the top center can be removed sooner or later. If the tree is weak and early, the strong tree can go later. After more than 10 years, the canopy can be lowered, with 1-2 main branches per year or every other year, and finally 4-5 main branches. This type of tree is suitable for more upright species, and this type of tree is used more frequently in Momo in Japan. Its advantage is that the main branch number is less than the evacuation layered shape, and the height of the tree is also lower. (4) Double Cup Shape This shape is a two-layer structure. After planting, dry it 40-60 cm from the ground and leave three evenly distributed main branches as the first layer. Up to 80-100 centimeters, select the remaining three main branches. The main branches of the upper and lower floors must be staggered. The main branch with the Deputy main branch. The branches between the layers cannot be removed prematurely so as not to affect the tree potential. This kind of tree has a short crown, convenient operation, good ventilation and light transmission, high fruit quality, relatively few main branches, and more branches. (5) After the colonization of the nursery stocks with fun-shape pods, in the branch of the main branch that is issued by the main branch, 30 to 40 centimeters from the ground, select 4-5 branches as the future main branch and alternate main branch, and remove the central branch. The distance between the main branches should be as far apart as possible. Do not concentrate on one point. If there are few haircuts in the first round and no three main branches are selected, the central sticks should be retained for the time being. The main branch is equipped with a deputy main branch. The balance between the main branches is resolved by adjusting the angle of the branches. For the main branch that is excessively strong, the angle should be enlarged; for the weak main branch, the angle should be reduced. Later, only 3-4 of them were selected as main branches. This tree shape is suitable for varieties with weak dryness and tree opening, such as big five-star varieties. This type of tree-shaped main branch is less, the result is more branches, the yield is higher; the ventilation and light transmission are good, the fruit quality is good; and the tree shape is short and is convenient for operation. 7 Dental Effects Natural Beef,7 Dental Effects Bulk Dog Food,7 Dental Effects Dog Bone Dry Food,Vegebrand 7 Dental Effects Jiangxi Welton Pet Products Co., Ltd. , https://www.weltonpetcare.com
