How can we do a good job of plant pruning?

1. 1 lawn mowing

Considering the seasonal characteristics and the growth and development characteristics of grass species, the height of grass is consistent and the edges are neat. The height of Taiwan Province grass should be controlled below 5cm, and the heights of Eupatorium adenophorum, centipede grass and Ophiopogon japonicus should be controlled below 65438 00cm.

1.2 Pruning of shrubs and flowers

Considering the growth and development characteristics of each plant, it is not only beautiful in appearance, but also can bloom in time with bright colors; Shrubs and herbaceous flowers should be pruned before flower bud differentiation to avoid cutting off flower buds, and residual flowers and branches should be cut off in time after flowers wither. Perennial flowering plants should cultivate flower branches purposefully to make flowers bloom in all seasons. The shaping effect of hedges and flower beds should be coordinated with the surrounding environment, enhance the landscaping effect, and carve out fine products with great care.

1.3 Tree pruning

Consider the growth characteristics of tree species, such as germination period and flowering period. Except for palm and other plants, other trees are generally pruned before the differentiation of leaf buds and flower buds, so as to avoid cutting off leaf buds and flower buds and make the flowers of flowering trees flourish; The shaping effect of trees should be coordinated with the surrounding environment to enhance the landscape effect. The pruning of street trees should keep the crown intact and beautiful, the distribution of main and side branches is balanced and the number is equal, and the interior is ventilated and transparent. The height of the lower edge line and the volume of the road arch should be determined according to the vehicle conditions in different sections. Generally, the height of trees should be controlled between10 ~17m, and care should be taken not to affect high-voltage lines, street lamps and traffic signs. If the branches and leaves of trees planted in the attached green space of the unit extend to urban public roads or other people's property, they shall be pruned in time; Pruning should be carried out in accordance with the operating procedures, try to reduce the wound, the incision should be flat, and no tree nails can be left; Shade branches, drooping branches, sprouting branches and dry branches and leaves below the lower edge line should be cut off in time.

1.4 Pruning of ancient and famous trees

Re-cutting the crown of severely aged ancient trees and cutting off the withered branches, so as to shorten the nutrient transport line in the trees, improve the circulation speed of body fluids and promote the development of strong branches. At the same time, the branches that are sick, over-aged, pests and diseases are properly pruned to achieve the purpose of ventilation and lighting of the crown and improve the growth and development conditions.

2. Secondary monitoring

2. 1 Lawn mowing

Considering the seasonal characteristics and the growth and development characteristics of grass species, the height of grass should be consistent and the edges should be neat. In Taiwan Province Province, the height of grass should be controlled below 5 cm, that of oil grass, Pteris vittata and attached grass should be controlled above 10 cm, and that of Wedelia chinensis should be controlled below 30 cm.

2.2 Pruning of shrubs and flowers

Considering the growth and development characteristics of each plant, it has beautiful appearance and can bloom in time; Flower shrubs and herbaceous flowers must be pruned before flower bud differentiation to avoid cutting off flower buds; Cut off the old branches of the residual flowers in time after the flowers wither. Hedges and flower beds should meet the requirements of landscaping.

2.3 Tree pruning

Consider the growth characteristics of each tree, such as leaf bud and bud differentiation period. The pruning time should be determined to avoid cutting off the flower buds so that the flowering trees can bloom in time; The effect of trees modeling should be coordinated with the surrounding environment as much as possible, and the pruning of street trees should keep the crown intact, the density of branches and leaves appropriate, and there should be no empty drum and ventilation. The height of the lower edge line and the crown volume should be determined according to the conditions of vehicles in different sections, and the height of trees should generally be controlled between10 ~17m, which will not affect high-voltage lines, street lamps and traffic signs. If the branches and leaves of trees planted in the attached green space of the unit extend to urban public roads or other people's property, they shall be pruned in time; Pruning should be carried out in accordance with the operating procedures, try to reduce the wound, the incision should be flat, and no tree nails can be left; Shade branches, drooping branches, sprouting branches and dry branches and leaves below the lower edge line should be cut off in time.

2.4 vertical greening pruning

When pruning, we should consider the growth and development characteristics of this species, determine the pruning time and degree, avoid cutting off useful leaf buds, flower buds and main vines, reasonably prune over-dense side vines, control the main vines, and make the coverage uniform to enhance the landscaping effect. The drooping vines on the overpass should be trimmed in time so as not to hinder traffic.

3. Three-level supervision

3. 1 Lawn mowing

Considering the seasonal characteristics and the growth and development characteristics of grass species, the edge of the green space is neat, the height of wedelia is controlled below 30 cm, and the heights of other grass species are controlled according to the situation, so that the green space presents a natural landscape effect.

3.2 Shrubs and flowers pruning

Beautiful shape, in harmony with the environment, flowers should bloom in time, and residual flowers and leaves should be trimmed in time.

3.3 Tree pruning

Cut off dead branches and diseased branches in time.
