brief introduction
stretch
Deciduous trees are trees whose leaves die and fall off at the same time when the cold or dry season comes; Evergreen trees are trees that are evergreen in spring and summer, and the old leaves gradually fall off after new leaves appear.
According to the duration of leaves, that is, all trees that have dead leaves within one year and all the old leaves fall off and then go into dormancy are always called deciduous trees. Trees whose leaves have died for less than one year are called evergreen trees. Generally, most deciduous trees are in temperate climate conditions, lush in summer and deciduous in winter, so they can be synonymous with summer green, and of course they also include trees that deciduous in tropical-subtropical dry season (Dipterocarpus in Myanmar and Thailand, etc.). ). In addition, not all dead leaves will fall off, and some trees overwinter with dead leaves.
Some common deciduous trees:
Sophora japonica, Sophora japonica, heavy willow, weeping willow, curved willow, straight willow, Albizia Albizia, weeping elm, Liriodendron chinense, Luan tree, Tung tree, Fawu, Qingfeng, Ginkgo biloba, Metasequoia glyptostroboides, Ailanthus altissima, citrus, tassel and Taxodium ascendens.
Reasons for cold resistance of larch:
Deciduous trees can resist cold and snow, because they can protect their roots well. In order to protect the roots, it scatters a part of itself-leaves, which slowly become fertilizer, absorbed by the roots and become the source of regeneration.
Question 5: What trees don't lose their leaves in winter? Most trees in the south don't hibernate, so they don't shed their leaves. Trees in the north only hibernate, and most of them don't shed their leaves if the temperature is right. The deciduous trees in the north are juniper, juniper, Platycladus orientalis, Korean pine and Mongolian pine. Mongolian oak, Chinese pine, fir, yew, red Piyun Mountain. However, pine trees also have fallen leaves, and larch is a pine tree that has fallen leaves in winter.
Question 6: Many trees lose their leaves in winter. What are the leaves of trees and plants? Generally speaking, the life span of leaves is only a few months, and some can live for two to several years. Leaves will fall off naturally when they live for a certain period of time. This phenomenon is called defoliation. There are two kinds of deciduous woody plants: one is that the leaves only live for one growing season and all fall off in winter. This kind of plant is called deciduous plant, such as willow; The other is that leaves can live for two to many years, mostly in spring and summer. After the new leaves appeared, the old leaves fell off for the last time. As far as the whole tree is concerned, it is evergreen all year round. This is called evergreen plants, such as conifers and cypresses. Defoliation can reduce water loss, and defoliation in late autumn or dry season can be regarded as an adaptation of plants to avoid excessive transpiration. Pine leaves are needle-shaped, also known as pine needles, which reduce transpiration area, have thick epidermis and developed cuticle. These structures can reduce transpiration and adapt to arid environment, so they are evergreen all the year round. The leaves of Buxus buxus and other plants have a thick cuticle with wax on it, so it can also reduce transpiration and be evergreen all year round.
Question 7: Which trees don't shed their leaves in winter? There are many. Almost all pine trees are long green (except money pine), such as cedar, Pinus tabulaeformis, Pinus massoniana and Pinus elliottii. Cypress; Platycladus orientalis, cypress, Sabina vulgaris, etc. There are also Magnolia grandiflora, Mahonia, Osmanthus fragrans, Cinnamomum camphora, Michelia, Pittosporum, Mosquito Mother Tree, Coral Tree, Euonymus japonicus, Holly, Schima superba, Ligustrum lucidum, Yellow Heart, Nerium oleander, Nandianzhu and so on.
