Today The editor briefly introduces the basic knowledge and precautions of greening maintenance for you, I hope it will be helpful to you!

1. Planting (transplanting):

1. Replanting season

Conifers, evergreen broad-leaved trees: replant after the soil has thawed in spring and before germination, or after the new shoots stop growing in autumn and before frost.

Deciduous trees: Replant after the soil is thawed in spring, before germination, or replant after the fall of leaves before the soil is thawed.

2. Make records before digging the dead trees and replant them as soon as possible. The trees to be replanted should be the original tree species, and the specifications should be similar. If the tree species or specifications are changed, it must be in harmony with the original landscape, and street tree replanting must be consistent with the tree species on the same road.

2. Irrigation and drainage:

1. In order for trees to grow normally, May to November is a critical period for tree irrigation.

2. The newly planted trees should be irrigated in an appropriate period and amount according to different tree species and different site conditions.

3. Trees that have been planted alive should be irrigated in time in an environment with long drought or poor site conditions and dry soil.

4. Saturate and irrigate thoroughly during irrigation, especially in spring and summer, to avoid low irrigation, which causes the upper half of the soil to be tight.

5. Summer irrigation should be carried out early and late, and winter irrigation should be carried out at noon.

6. In autumn (after late August), reduce irrigation appropriately, control the growth of seedlings, and promote timely lignification of seedlings to facilitate overwintering.

7. Before winter, the trees are generally watered once to protect the trees from overwintering and prevent spring drought. After heavy rains around the trees, the accumulated water should be removed in time, especially for newly planted trees.

3. Fertilization:

1. Widely open up fertilizer sources, accumulate manure all the year round, mainly accumulate organic fertilizer, and apply organic fertilizer after fully decomposed.

2. Fertilization during dormancy: early spring or late autumn, and the fertilizer is organic fertilizer such as compost. It can be combined in winter.

3. Fertilization during growth period: In spring or autumn, the fertilizer is mainly quick-acting inorganic fertilizer, combined with watering. Spread fertilizer when fertilizing, when the soil is wet or moist after rain; or water after fertilization. For tall trees, use hole application, dig even holes around the roots, cover the soil and water after the fertilizer is applied. In special cases, use extra-root fertilization, and spray the fertilizer solution directly on the back of the leaves with a sprayer.

4. Pruning and shaping:

1. Pruning during the dormant period: deciduous trees are mostly carried out during this period. Evergreen trees have no obvious dormant period. Winter pruning will have an adverse effect on the tree body. Pruning is usually done in late spring after the severe cold season.

2. Growth period pruning, also known as summer pruning: the pruning time should not be too late, otherwise it is easy to cause secondary shoots and consume nutrients, which is not good for the growth of new shoots. At the same time, the amount of pruning is appropriate.

3. Pruning of deciduous trees: pay attention to maintaining the growth potential of the top tips, set aside first-level skeleton branches every 20-25 cm at the branch point, and maintain the top growth advantage on the skeleton branches, and keep them at regular intervals. A secondary branch, and so on, thin out the extra long branches, drooping branches, etc.; evergreen broad-leaved trees: keep the central main branch, properly handle the skeleton branches, and keep the branches evenly distributed; evergreen conifers: pay attention to cultivation and balanced growth when pruning The potential is sufficient. Under normal circumstances, pruning is not carried out, but pay attention to avoid the phenomenon of double stems and double heads.

4. Hedge trimming: Hedgerows generally have strong budding power, strong branching power, and pruning resistance. Generally, regular pruning is the main method to keep the appearance neat and beautiful, and to avoid emptiness inside and baldness in the lower part.

5. Pruning of vines: Generally, trimming is seldom carried out, mainly by cutting off side branches, cutting off diseased branches and dead branches, and appropriately thinning weak branches.

6. Pruning of spring flowering plants, such as bauhinia, crabapple, yellow syringa, white magnolia, etc.: pruning within 1 to 2 weeks after flowering to reduce nutrient consumption, promote multiple lateral branches, and increase flowering in the coming year; in winter dormancy , Flower buds have been basically formed, flower buds and leaf buds can be clearly distinguished, and branches can be thinned appropriately, and weak branches, diseased dead branches, budding branches and branches without flower buds can be cut off appropriately.
