Detailed Explanation of the 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 is widely distributed in China. The new buds of Chinese toon are edible, and the tree has a good structure, so it is also a tree species suitable for ornamental use. It is widely used in major gardens. The toon buds are rich in nutrients and can be used to treat wind-cold and stomach pain, among other things. So how should it be managed when planting Chinese toon? Below, the editor brings you the key points of field management for Chinese toon. Let's take a look!
1. Seedling management
Chinese toon seeds will emerge about one week after sowing. Before they emerge, 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 they should be watered 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 vegetative growth of the seedlings and increases nutrient accumulation. 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°C, the Chinese toon buds will grow by about 3 cm. When the temperature is around 16°C, the growth of Chinese toon buds will be significantly inhibited. However, the temperature should not be too high either. When it exceeds 32°C, both the color and quality of the Chinese toon buds will decline. About half a month after the shed is covered, Chinese toon enters its seedling recovery period. At this time, the daytime temperature should be controlled at around 30°C. Then, after the toon buds sprout, lower the temperature to around 26°C, and keep the nighttime temperature at around 15°C. Then, according to weather changes, do a good job of heat preservation and cooling.
3. Water and fertilizer management
The root system of Chinese toon is relatively shallow, so its ability to absorb water 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 at the right time according to soil conditions. Keep the air humidity above 80%. During periods of high temperature and drought, spray water on the seedlings to prevent water loss from causing the seedlings to dry up. However, the humidity should not be too high either, otherwise it will delay the germination time of Chinese toon and reduce the quality of the Chinese toon buds. During its 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
When harvesting Chinese toon buds for the second time, attention should be paid to removing the top of the Chinese toon and doing the trunk determination work well to promote the growth of subsequent new buds. Then, after the trunk of the Chinese toon is determined, spray agents such as paclobutrazol once in time to inhibit the growth of the top branches of the 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 the Chinese toon, do the topping and branch removal work well 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 the management work well, the Chinese toon buds can be harvested continuously. That is all for today's introduction.
