1. 1 spring scissors

Spring pruning of Toona sinensis belongs to modeling pruning, which is usually carried out at the same time as the harvesting of Toona sinensis buds. From the second year after the cultivation of Toona sinensis, the top buds of 2-year-old trees will be removed, and 2 ~ 3 new buds will sprout in that year. If the height of the trunk is suitable, new buds can be retained and become 2 ~ 3 lateral branches after lignification; If the height of the trunk is too high, the new buds can be cored (not all buds can be picked) to promote the lower buds to sprout new buds. According to the required position, 2-3 sprouted new buds can be retained and become lateral branches after lignification. After the third year, new buds will be born at the top of the three lateral branches.

When pruning, the top buds of three lateral branches are removed. In that year, two or three new lateral buds will grow on each lateral branch, and new lateral branches will be formed after lignification. After this formation, each tree has 6 ~ 9 main branches. This kind of tree has high trunk, large branches, thick canopy, good ventilation and lighting, large harvest area and stable output.

1.2 Xia Jian

Because the yield and quality of Toona sinensis mainly depend on the number of terminal buds, more branches and terminal buds per unit area can produce higher yield, so it is necessary to trim Toona sinensis trees in summer to promote the formation of more branches. Pruning in summer is generally carried out on sunny days 15 in July and August, which is beneficial to wound healing, and it is not suitable for pruning on cloudy days. On the pruned Toona sinensis tree, the overgrown and overgrown branches are topped or truncated to promote the sprouting of lateral buds to form new branches, rejuvenate weaker parts and form more short lateral branches with full terminal buds.

1.3 winter scissors

Winter pruning is best carried out in early winter (or late autumn) and early spring dormancy period. Sparse dense branches, weak branches, pest branches, dead branches and perennial old branches with 1 tree age. Pruning knives and axes should be sharp. When pruning, they should stick to the trunk and cut it from bottom to top. The incision should be smooth and the wound should be small. Never move or strain the bark, which will affect the growth and development of trees.

1.4 rejuvenation

After harvesting for 7 ~ 8 years, when the budding part moves to the outer layer of the crown, the growth becomes weak, and the new buds are few and thin, indicating that the tree head is aging and should be replaced and updated. Head-changing is usually carried out when buds are picked in spring. Methods: From the third year, cut off the branches and leave stubble, that is, cut off the first branch.

All branches born after 3 years. Note that the stubble length of branches in the third year should be 20 ~ 30cm, so as to promote the development of new branches and keep the trees intact and robust. In the second year after the head change, new buds will grow on each stubble, but excessive pruning will cause the tree to grow poorly. If the stubble is not enough, new buds will often grow on the backbone branches in the second year, making the situation of the tree worse. Some rejuvenation only leaves the trunk, which will cause multiple branches to regenerate, and excessive pruning will also cause tree death.

Question 2: How to prune the Toona sinensis tree to make it grow well? Spring pruning: spring pruning belongs to modeling pruning, which is usually carried out at the same time as the harvesting of Toona sinensis buds. From the second year after cultivation, the top buds of 2-year-old trees will be removed, and 2 ~ 3 new buds will sprout in that year. If the height of the trunk is suitable, new buds can be retained and become 2 ~ 3 lateral branches after lignification; If the height of the trunk is too high, the new buds can be cored (not all buds can be picked) to promote the lower buds to sprout new buds. According to the required position, 2-3 sprouted new buds can be retained and become lateral branches after lignification. After the third year, new buds will be born at the top of the three lateral branches.

When pruning, the top buds of three lateral branches are removed. In that year, two or three new lateral buds will grow on each lateral branch, and new lateral branches will be formed after lignification. High trunk, large branches, thick canopy, good ventilation and lighting, large harvest area and stable yield.

Pruning in summer: Pruning in summer is generally carried out on sunny days 15 in July and August, which is beneficial to wound healing, and it is not suitable for pruning on cloudy days. On the pruned Toona sinensis tree, the overgrown and overgrown branches are topped or truncated to promote the sprouting of lateral buds to form new branches, rejuvenate weaker parts and form more short lateral branches with full terminal buds.

Winter pruning: Winter pruning is best carried out in early winter (or late autumn) and early spring dormancy period. Sparse dense branches, weak branches, pest branches, dead branches and perennial old branches with 1 tree age. Pruning knives and axes should be sharp. When pruning, they should stick to the trunk and cut it from bottom to top. The incision should be smooth and the wound should be small. Never move or strain the bark, which will affect the growth and development of trees.

Question 3: Toona sinensis is too high. Can I cut the waist? Waist shears are ok, but before spring germination, don't lose too much nutrients now, and the roots will be affected.

Question 4: How to prune Toona sinensis trees? The more buds, the better. The purpose is to pick more Toona sinensis, not too high, because the pole is too high to pick. Should be beheaded more.

Question 5: The Toona sinensis tree in my house is too high. When will it be trimmed? If you must prune it now before winter in spring or autumn, it is recommended to choose proper shade the next evening. It will take a few days to bring an umbrella or something.

Question 6: It's almost May. Can Toona sinensis trees be pruned? This question can only give you a reference opinion. If you want the branches above to fall off, you need to cut them to the front with branches. If the trunk falls down, you need to leave branches, otherwise the hidden buds will not germinate, which will be very troublesome. Besides, most trees have sprouted at present, at least. Short cutting has a great influence on tree potential. You can cut all the branches short in the future.

Question 7: When will the Toona sinensis tree be trimmed? It was only one meter high last year, but now it has grown to four or five meters high. That is to say, the new branches are 3-4 meters this year, which is a bit mysterious. But in any case, it can still be repaired at this time. If there are no branches or one by one, cut them off at a place more than one meter to facilitate the picking of Toona sinensis. If it interferes with people's actions, it can be higher.

Question 8: What should I do if the Toona sinensis tree is cut off? Graft those 2B on.

Question 9: How to trim Toona sinensis? The more buds, the better. The purpose is to pick more Toona sinensis, not too high. High poles are not conducive to picking. Should be beheaded more. Pruning after the first picking in spring is the best.

Question 10: Why does Toona sinensis grow so fast? Toona sinensis is a unique fast-growing tree species in China, with unique growth characteristics and long growth period, and it grows fastest when it is 9- 18 years old. The growth adaptability is relatively strong and the growth is relatively rapid. As long as the water keeps up, it can grow faster and more vigorously. The growth characteristics of Toona sinensis are worth studying and developing.

? The growth temperature of Toona sinensis is between 7℃ and 28℃, and the growth temperature is relatively wide. It is also a direct root system. Generally, the roots are deeply embedded in the ground and are longer than the trunk on the ground. It can absorb underground water and nutrients, supply plants with rapid growth and development, and grow into towering trees in a short time.

? Toona sinensis belongs to Meliaceae, a perennial deciduous tree.

? Toona sinensis is a precious woody vegetable. Its terminal buds and leaves are crisp and juicy, with rich aroma, unique flavor and rich nutrition.

? Toona sinensis is rich in protein, amino acids, various volatile oils, vitamins and trace elements.
