Can I plant trees in winter? Will it survive? When is the best season to plant trees?

In recent years, with the implementation of various forestry ecological projects, increased tree planting tasks, short project time and other factors, many garden enterprises also have to plant a large number of trees in winter. So, can trees be planted in winter? Will it survive? When is the best season to plant trees? How about summer and autumn? Let's take a look at it.

1. Trees can also be planted in winter to meet the requirements and survive.

Planting trees in winter has a series of advantages: first, the temperature is low, the air humidity is high, the evaporation is small, the seedlings are not easy to lose water in the process of transplanting, and can keep more water; high ground temperature and high humidity are beneficial to the formation of callus in root system. Rooting absorbs water and nutrients. Second, the seedlings are dormant in winter and the roots heal better. The third is to plant trees in winter, and when it comes to spring, the trees will sprout early and their roots will be strong. But when planting, you will face the following problems:

The selection range of tree species suitable for planting in winter is less than that in spring.

Compared with spring, the cost of planting is higher. Whether it is digging trees or digging holes when planting, the labor cost is relatively high, and the maintenance cost is increased. After planting trees in winter, we often have to spend a certain amount of money to do secondary maintenance in spring, such as hydrosphere reinforcement, support reinforcement. At the same time, it is necessary to wrap straw rope or non-woven cloth after planting in winter, which also increases the cost of maintenance.

The quality of tree planting projects in winter can not be well guaranteed, which is especially obvious in the north. In winter in the north, the soil has been frozen, which increases the difficulty of digging tree holes in places where machines cannot be used, resulting in too small or too shallow tree holes, resulting in frozen roots after planting trees.

Planting trees in winter is easy to be affected by frost injury, which affects the survival rate of trees. There is often a sudden low temperature in the planting process, but the heat preservation measures for the newly planted trees have not yet been done, which is likely to cause frostbite. Second, even if the heat preservation measures have been done, the rare low temperature will cause frostbite to the trees. Deciduous trees planted in winter suffer better, but some evergreen trees die from frostbite at low temperatures.

two。 It is best to plant trees in spring, but summer, autumn and winter are not conducive to survival.

The survival rate of planting trees in spring is higher, the main reasons are: first, the temperature rises in spring, the sun and Rain Water increase, the soil is moist, which is beneficial to the growth of trees; second, the branches and leaves of trees have not germinated in large quantities in spring, and the water emission is relatively less. The demand for root water supply and nutrients is not very urgent, even if there is damage when planting, it is also easy to recover.

In winter and autumn, a large number of leaves fall off, and the metabolism of trees slows down, which is not conducive to survival. When the temperature is high in summer, the transplanting root system of the seedlings will be damaged, and a large amount of transpiration will make the seedlings dry to death and not easy to survive.
