Latest Key Points of Field Management Techniques for Chinese Toon
Chinese toon (Toona sinensis) is a deciduous tree with a relatively large tree form, and it has a wide distribution range in China. The new buds of Chinese toon are edible, and the tree structure is good, so it is also an ornamental tree species. It is widely used in major gardens, and the toon buds are rich in nutrients and can be used to treat wind-cold stomach pain and other conditions. So how should Chinese toon be managed when planting? Below, the editor brings you the key points of field management for Chinese toon. Let's take a look together!
1. Seedling management
Chinese toon seeds will emerge about one week after sowing. Before emergence, attention should be paid to keeping the soil moist to prevent soil crusting from reducing the emergence rate. When the seedlings grow to about 5 true leaves, the work of final thinning and spacing should be done well, and water should be given once before final thinning. Then the plant spacing should be controlled at about 22 cm. When the seedlings grow to about 50 cm, the dwarfing work should be done well, using agents such as paclobutrazol to spray once every half month, for about 3 times. This prevents excessive seedling growth, improves nutrient accumulation, and when spraying, pinching should also be done well to increase the number of branches on the seedlings.
2. Temperature management
Chinese toon is relatively sensitive to temperature changes. When the temperature is around 24 degrees, Chinese toon buds will grow by about 3 cm. When the temperature is around 16 degrees, the growth of Chinese toon buds will be significantly inhibited. However, the temperature should not be too high either. When it exceeds 32 degrees, the color and quality of Chinese toon buds will decline. About half a month after the shed is covered, Chinese toon enters the seedling recovery period. At this time, the daytime temperature should be controlled at around 30 degrees. Then, after the toon buds sprout, lower the temperature to around 26 degrees, and keep the nighttime temperature at around 15 degrees. Then, according to weather changes, do a good job of heat preservation and cooling.
3. Water and fertilizer management
The root distribution of Chinese toon is relatively shallow, so its water absorption capacity is poor. Therefore, in the early stage of planting, we should pay attention to maintaining soil moisture content and air humidity. After planting, water thoroughly, and then water timely according to soil conditions. Keep air humidity above 80%. During high temperature and drought, spray water on the seedlings to prevent water loss from causing the seedlings to dry up. But humidity should not be too high either, otherwise it will delay the germination time of Chinese toon and reduce the quality of Chinese toon buds. During the growth process, Chinese toon has a relatively large demand for potassium fertilizer, so when fertilizing, we should pay attention to applying more potassium fertilizer and farmyard manure to meet the nutritional needs of Chinese toon.
4. Topping to promote branching
During the second harvest of Chinese toon buds, attention should be paid to removing the top of the Chinese toon and doing a good job of trunk determination to promote the growth of subsequent new buds. Then, after the trunk of Chinese toon is determined, promptly spray once with paclobutrazol and similar agents to inhibit the growth of the top branches of Chinese toon, prevent excessive growth, and promote the growth of branches. This achieves the purpose of dwarfed planting. Then, in the later stage, according to the growth condition and tree form of Chinese toon, do a good job of topping and branch removal to increase the number of branches of the Chinese toon tree, increase the yield of Chinese toon buds, and enhance quality.
The above is a brief introduction to the key points of field management for Chinese toon. The edible part of Chinese toon is the Chinese toon buds, so as long as we do a good job in management, Chinese toon buds can be harvested continuously. That is all for today's introduction.
