Key points of field management of Toona sinensis

Toona sinensis is a deciduous tree with a large tree shape and a wide range of distribution in China. Toona sinensis sprouts for food, and tree structure is good, but also a species for viewing. It is widely used in various gardens. Chinese toon sprouts are rich in nutrients and can be used to treat stomachache due to cold. So how do you manage it when planting toona? The following small series brings you the key points of field management of Chinese toon. Let's have a look together!

1. Seedling management

Toona sinensis seeds will emerge about a week after sowing. When they have not emerged, attention should be paid to keeping the soil moist to prevent soil hardening from reducing the emergence rate. When the seedlings grow to about 5 true leaves, they should do a good job of thinning seedlings, watering once before setting seedlings. Then the plant spacing is controlled at about 22 cm. When the seedlings grow to about 50cm, dwarf work should be done well, and paclobutrazol and other chemicals should be sprayed once every half month for about 3 times. Prevent excessive growth of seedlings, improve nutrient accumulation, and do a good job of picking when spraying, so as to improve the number of branches of seedlings.

2. Temperature management

Toona sinensis is more sensitive to temperature changes, when the temperature is about 24 degrees, Toona sinensis buds will grow about 3 cm. When the temperature is about 16 degrees, it will obviously inhibit the growth of Toona sinensis buds. However, the temperature should not be too high, when more than 32 degrees, the color quality of Chinese toon buds will decline. About half a month after the shed is buckled, it will enter the seedling stage of Chinese toon. At this time, the temperature should be controlled at about 30 degrees during the day. Then when the Chinese toon sprouts, reduce the temperature to about 26 degrees, and keep the temperature at about 15 degrees at night. According to the 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, we should pay attention to maintaining soil moisture and air humidity in the early stage of planting. After planting, we should irrigate enough water, and then water according to the soil conditions. Keep air humidity above 80%. In high temperature and drought, water spray should be carried out on seedlings to prevent water loss leading to seedling drying. However, humidity should not be too high, otherwise it will delay the germination time of Chinese toon and reduce the quality of Chinese toon buds. Toona sinensis in the growth process of potassium demand is relatively large, so we should pay attention to the fertilization of potassium fertilizer and farm manure, to meet the nutritional needs of Toona sinensis.

4. Topping and promoting branches

When harvesting Chinese toon buds for the second time, we should pay attention to picking off the top of Chinese toon, do a good job of drying, and promote the growth of subsequent new buds. Then spray paclobutrazol once in time after Chinese toon is dry, inhibit the growth of top branches of Chinese toon, prevent flourishing and promote the growth of branches. To achieve the purpose of dwarfing planting, then in the later stage, according to the growth situation and tree shape of Chinese toon, the top and branch work should be done well, so as to improve the branch quantity of Chinese toon tree, increase the yield of Chinese toon bud and enhance the quality.

The above is a brief introduction to the key points of Toona sinensis field management. The edible part of Toona sinensis is Toona sinensis bud, so we only need to do a good job of management. Toona sinensis buds can be harvested continuously. Today's introduction is here, this article is for reference only, thank you for reading and support.
