Problems solved by technology

However, for a long time, due to lack of understanding of the law of tree growth and development by gardeners, there are some misunderstandings in pruning management.
[0009] The production unit neglects the cultivation of the tree shape of the ash street tree, and there are problems such as letting its branches grow or pruning improperly, and strong randomness, which seriously affects the normal growth of the ash tree trunk and crown, resulting in too short trunk height or skewed branches. Not only will it affect the traffic of vehicles, Moreover, in spring and summer, the dense leaves will affect the driving line of sight and cause driving safety hazards.
[0010] Ash saplings grow fast. If the cultivation of the tree shape is not paid attention to or the cultivation is not timely, the branches of the trees will prolong and grow all the year round, causing the main and side branches of the street tree to be unclear and without hierarchical structure; Excessive light pruning and slow release of side branch extension branches, main and side branch extension branches are weak, branch angles are too open or drooping, resulting in uncompact crown shape, chaotic tree shape, and different sizes, resulting in poor crown stability, windproof, The ability to prevent diseases and insect pests is poor. In the windy weather, it is easy to break, so that the traffic will not change, and even other buildings will be damaged.

Abstract

The invention belongs to the field of plant cultivation, and particularly relates to a landscape tree shape cultivation method for a fraxinus chinensis street tree. The method comprises the steps of cultivation of a trunk, cultivation of skeleton branches and cultivation of a crown shape. According to the method, a current annual cultivation method is adopted for the early tree shape cultivation of a fraxinus chinensis sapling, continuous shape cultivation of 4-6 years is conducted, and therefore the fraxinus chinensis tree is full and attractive in crown shape, neat in plant shape and beautiful in posture. By means of the tree shape cultivation method, the reasonable crown structure is kept, all stages of branch structures are distinct in layer, the overall tree potential is balanced andstable, and the stability of the fraxinus chinensis tree in strong storm and rain can be enhanced. By means of the method, dense branches and thin and weak branches are timely removed, the density ofthe branches is consistent, the side branches are evenly distributed, the interior of the crown is ventilated and is pervious to light, the leaves are dark green and luxuriant, and the occurrence of diseases and pests of the fraxinus chinensis tree is reduced.

Description

technical field [0001] The invention belongs to the field of plant cultivation, and in particular relates to a method for cultivating the landscape tree shape of ash street trees. Background technique [0002] Ash tree belongs to Osmanthus family, Osmanthus genus, deciduous tree. It is distributed from the central and southern part of Northeast China through the Yellow River Basin and the Yangtze River Basin in the north, to Guangdong and Guangxi in the south, to Fujian in the southeast, and to Gansu in the west. This tree species has strong adaptability, likes light, likes warm and humid climate, has well-developed root system, grows fast, does not have strict requirements on soil, is resistant to barrenness, can grow on both loam and clay soil, and has certain salt-alkali tolerance. It can still grow on 0.3% to 0.5% soil, and can grow in both acidic and calcareous soils; it has strong resistance to smoke and dust, sulfur dioxide, chlorine, and hydrogen fluoride, and has s...
