It is best to prune Toona sinensis trees in spring to keep pace with the harvest of Toona sinensis buds. The specific time is from the second year. After the terminal buds of 2-year-old trees are removed, 2-3 new buds will grow in the same year, and 2-3 lateral branches will be formed after lignification. Cutting: When cutting Toona sinensis, select semi-lignified branches with the length of 15~20cm, cut off the bottom leaves, soak them in rooting water for half an hour, water the seedbed, insert the cuttings into the soil 5cm deep, and then move them to a ventilated and backlit environment to keep the soil moist until the branches take root for about half a month.
How to prune the branches and leaves of Toona sinensis
1. Spring pruning: Spring pruning of Toona sinensis belongs to modeling pruning. From the second year after cultivation, the top buds of 2-year-old trees will be removed, and 2~3 new buds will grow in that year. If the height of the trunk is suitable, new buds can be kept. If the height of the trunk is too high, new buds can be picked to promote the germination of the lower buds. 2. Summer pruning: Summer pruning of Toona sinensis trees is generally carried out on sunny days in July and August, which is conducive to wound healing. Cloudy days are not suitable for pruning. In the trimmed Toona sinensis tree, the branches that are too strong and too high should be cut short to promote the germination of lateral buds. 3. Pruning in winter: It is best to prune Toona sinensis in early winter and early spring to remove annual dense branches, weak branches, branches with pests and diseases, dead branches and old branches. Pruning should be close to the trunk, from bottom to top, and the incision should be flat.
Pruning skills of Toona sinensis trees
1. coring: after the tender branches of Toona sinensis tree are removed, after a period of time, new branches will grow in this branch. These new shoots are its heart, so they are usually picked in spring. When it grows to a certain height, you can branch and sprout. 2. Germination: Toona sinensis trees should germinate after coring. Gloves are generally needed to pick the budding leaves to prevent excessive consumption of nutrients. 3. Long branches: When pruning Toona sinensis, cut off the long branches. Too long branches will affect the light intensity of other plants. When pruning, the length can be controlled at about half a meter to avoid being too long.
How can Toona sinensis trees grow fast by pruning?
The pruning of Toona sinensis is mainly divided into three links, namely, fixed stem, growth period pruning and dormancy period pruning. 1. Drying of potted Toona sinensis: The most important thing for potted Toona sinensis is to control the height and increase the yield. The first step to control the height of Toona sinensis is to trim the trunk of Toona sinensis to 15-20cm. Drying is usually carried out before germination in spring, and 3-8 new branches can be issued in that year. 2. Pruning in summer: For 3-8 new branches of Toona sinensis that germinate after drying, 3-5 branches with better growth can be selected according to the situation, and other redundant branches can be cut off in time. When the remaining branches grow to 10- 15 cm, the first pruning in summer can be carried out. 3. Dormancy pruning: If the potted Toona sinensis saplings are pruned timely and correctly in summer, then there is no need for dormancy pruning. If it is not pruned well in summer, it can also be pruned during hibernation.
Matters needing attention in pruning Toona sinensis trees
When picking the second crop of Toona sinensis, be sure to top it. When the wound is dry, spraying paclobutrazol solution can control the apical advantage, promote the rapid growth of branches and realize dwarfing culture.
