What season is the "living fossil" ginkgo tree in? Key points of cultivation techniques
The ginkgo tree is a precious tree species in China, and its leaves and fruit have certain medicinal and edible value. The shape of the ginkgo tree's leaves is like a fan, drifting down to the ground with the wind, a sheet of golden yellow, a beautiful sight not to be missed.There are many varieties of ginkgo trees, and their requirements for the growing environment also differ. Let's take a look below at the “living fossil” What season is the ginkgo tree in? What are the key points of cultivation techniques?
I. What season is the “living fossil” ginkgo tree in?
Around the Start of Winter, it is the most beautiful time for the ginkgo tree. The ginkgo leaves all over the tree turn from green to yellow, a pure yellow, a clear yellow, a stunning yellow. Generally, they can be found on campuses and along both sides of roads, and you will always find some ginkgo lovers picking up their leaves and pressing them into books, which is very poetic.
The ginkgo tree is an economic tree with good planting prospects. Its wood is solid and fine in texture, with simple, plain grain and a pale yellow color, making it a high-quality material for construction and industry.
The ginkgo tree has a good greening effect and is suitable for planting in gardens or along both sides of roads. In recent years, although the price trend has not risen markedly, there is still some room for development.
The fruit of the ginkgo tree is rich in nutritional value and has a very unique taste, making it deeply loved by consumers.
II. Key points of ginkgo tree cultivation techniques
1. Propagation methods
When planting ginkgo trees in the north, sowing is done in spring, while in the south it is done in autumn. Before sowing, the seedbed must be chosen well. Sandy soil with good looseness and strong drainage is relatively suitable for planting ginkgo trees. If cutting propagation is chosen, then a current-year soft branch from May or June should be selected, and a 10 to 15 cm branch should be trimmed and inserted into the soil, then watered frequently; generally it will take root in one to two months. However, do not water too much at one time, and be careful not to let water accumulate.
2. Key points of fertilization
Fertilization of nursery land can be carried out in spring and summer, and the amount and frequency of fertilization should be determined according to the growth condition of the ginkgo tree.
3. Pruning work
Ordinarily there is no need to prune the ginkgo tree, because its new shoots do not grow much, and its branches and leaves should be kept as abundant as possible to allow its trunk and branches to thicken. In the year before sale, simply prune off the branches below 1.8 m.
4. Cultivation work
Proper cultivation can improve the soil's aeration conditions. Cultivation also plays a pruning role for the ginkgo's fibrous roots, which can stimulate more fibrous roots to sprout. Cultivation once each in spring and autumn is enough.
5. Pest and disease control
The main disease of the ginkgo tree is damping-off disease during the seedling stage. In addition, it is also attacked by scarab beetle larvae and others. Once symptoms are found, control should be carried out promptly, and try as much as possible not to let it affect the beauty of the leaves. If the disease is controlled early, the spread of the disease can also be reduced.
