Unconsciously, more than half of it has been in 2019, and now it has entered the late autumn. There are still many things to be aware of when planting trees in this season. The temperature in autumn is gradually decreasing, the water transpiration is low, the moisture content in the soil is stable, and the soil temperature is still In the high case, the roots of the cold-tolerant tree species planted in autumn can resume growth, so the survival rate is higher. The transplanting of seedlings in autumn can be carried out in late October or early November, that is, transplanting before the soil is frozen. Generally speaking, planting trees in autumn requires the following five "not suitable". "Five not suitable" for planting trees in autumn: 1, transplanting time should not be early Prerequisites for planting trees are better: first, the temperature is lower; second, the leaves are largely shed. The transpiration of trees with low temperatures can be reduced, which is conducive to the survival of trees. Some people plant trees in advance in order to speed up the construction period. Although measures such as increasing soil ball have been taken, the survival rate cannot be guaranteed. Therefore, the best choice for seedling planting is to be carried out after the beginning of November. Generally, it can be used before the freezing. For some trees with early leaves, trees such as Qingtong, Guojiao and Fatong can also be planted in late October. 2, planting should not be shallow When planting trees in the fall, the depth should be slightly deeper than the trees planted in the spring. The reason is that the temperature in winter is low. If the planting is too shallow, it is very easy to cause freezing damage to the roots of the trees. In addition, the deep planting of autumn trees is also conducive to the eruption of new roots. The planting depth should be 5 cm to 8 cm higher than the original soil marks in the rhizome of the tree. In the spring of the next year, combined with the pouring of frozen water, the topsoil can be opened. This will help the trees to erupt new roots in winter, ensure the survival rate, and also the trees. It is beneficial to pump new sprouts in the spring. 3, fertilizer should not be lacking Many people think that trees do not grow in autumn and winter, and fertilization is a waste at this time. In fact, this view is wrong. Planting trees in the fall is necessary for proper fertilization. Fertilization at this time has two functions. One is to effectively raise the ground temperature, which is good for erupting new roots, and the other is to provide sufficient nutrients for new roots, which is good for sprouting long branches in spring. 4, watering should not be less Planting trees in autumn, watering work is very important, the number of watering should be determined according to the planting time. Trees planted in late October need to be poured with three waters, that is, immediately after planting, watering the head water, pouring water for two days, and then pouring three waters after 15 days. The trees planted in the middle of November are poured with at least two waters, that is, the water is poured immediately after planting, and the water is poured for 15 days. At the beginning of December or the trees planted before the freezing, only one water is poured, that is, watered after planting. In short, the watering must be poured into the water, and the water should not be small. 5, trim can not save Although the transpiration in autumn and winter is lower, proper pruning is also very beneficial to improve the survival rate of trees. Therefore, the pruning before planting cannot be saved. When pruning, it should be carried out according to the ecological habits and ornamental needs of the trees. The combination of sparse and short cuts will preserve the branches to the maximum extent to ensure the survival of the trees. For larger wounds, a wound healing agent should be used for protection.
