technical field

The invention relates to the technical field of seedling planting, in particular to a method for improving the survival rate of seedlings in coastal cities.

Background technique

Plants can absorb carbon dioxide, release oxygen, and purify the air; to a certain extent, they can absorb harmful gases and absorb dust to reduce pollution; they can adjust the temperature and humidity of the air to improve the climate; Seedlings are often used for urban greening, residential area greening, road greening, barren hill greening, river embankment greening, etc. Transplanting seedlings for greening can not only create beautiful gardens, but also protect and improve the environment. With the rapid development of urban construction With the continuous improvement of landscaping level, big tree transplanting technology is more and more widely used in improving urban ecological environment and green land landscape, improving the quality of urban greening and so on. There are following problems at prior art:

Because the existing seedling transplanting and planting methods are too simple, the simple method of digging pits and pre-burying is used for transplanting, and coastal cities are often accompanied by sea breeze all the year round, which leads to the problem that the survival rate of seedlings will decrease after transplanting in coastal cities. Since the existing seedlings are cross-supported by brackets after transplantation, and then tightened with iron wires, the installation steps are cumbersome, time-consuming and labor-intensive, and because the seedlings continue to grow and become thicker, the traditional bracket fixation will inhibit the growth of the seedlings. production, it also needs to be replaced periodically, resulting in a problem of raising costs.

A1: The amount of pruning varies with different tree species and landscape requirements. For larger deciduous trees, especially those with strong growth potential and easy new branches, strong pruning can be carried out, and the crown can be reduced to more than half. For tall deciduous trees, the original tree shape should be maintained, and the branches should be thinned appropriately. The retained main and side branches should be cut short on the strong buds, and 1/5 to 1/3 of the branches can be cut off. The deciduous trees with no obvious trunk and dense branches , with a trunk diameter of 5 cm to 10 cm, you can choose to keep a few side branches on the main trunk and keep the original tree shape for short cutting;

A2: Evergreen trees with dense branches can be thinned appropriately. Seedlings whose branches and leaves are concentrated on the top of the trunk can not be pruned, but only burn leaves. Evergreen coniferous trees should not be pruned more. Only cut off diseased and insect branches, dead branches, and weak growth branches , excessively dense whorled branches and drooping branches, and the canopy of precious tree species should be kept as little as possible and cut less. Wounds caused by tree pruning should be coated with protective agents, such as paint, Vaseline, etc.
