Detailed Explanation of Toona sinensis Planting Methods and Technical Points

Toona sinensis (Chinese mahogany) is a perennial deciduous tree that can grow to over ten meters tall. Although it is a tree, its new leaf buds are an excellent vegetable, rich in nutrients and with excellent therapeutic effects, mainly treating wind-cold, rheumatism, stomach pain, dysentery, and more. Toona sinensis is extremely popular on the market, and its market price is also relatively high; in some regions it sells for over ten yuan per jin. So how should it be planted? Come take a look at QinNong Web.

1. Seed Selection and Germination

Select seeds from the current year. The seeds must be plump and red-yellow in color. After selecting the seeds, germination treatment should be carried out to increase the germination rate and ensure uniform seedling emergence. First, place the seeds in warm water at about 40 degrees for 5-8 minutes, stirring constantly during soaking. After soaking, remove them and place them in room-temperature water for one day. Once the seeds have fully absorbed water, remove them and drain. Then spread the seeds on a bamboo mat; the spreading thickness should not exceed 3cm to avoid heat buildup that could damage the seeds. After spreading, cover with a towel and place in an environment of 20-25 degrees for germination. During germination, turn the seeds occasionally and rinse with clean water at the same temperature as the germination environment. After draining, continue germination. When one-third of the seeds begin to sprout, they are ready for sowing.

2. Sowing and Seedling Cultivation

Choose flat terrain with sufficient sunlight, convenient irrigation and drainage, and fertile, loose sandy soil as the seedbed. Rake the soil fine and level it, apply some fertilizer for seedling emergence, spread it evenly, then deep plow. Open furrows for sowing with a furrow width of 5-6cm, furrow depth of 5cm, and row spacing of 1 meter between furrows. Evenly scatter the germinated seeds, cover with a layer of fine soil, control the temperature at 20-23 degrees, weed regularly, and maintain soil moisture and air humidity. Seedlings will sprout and emerge within one week. During the seedling stage, strengthen fertilizer and water management to promote seedling growth. When the seedlings emerge and grow 4-6 true leaves, thin and set the seedlings in time. When the plants grow to 50cm, carry out dwarfing to increase yield; this can be combined with spraying paclobutrazol and pinching to increase the number of branches on the plant.

3. Transplanting

After completing the plant dwarfing measures, transplanting can be carried out. For transplanting, choose greenhouse cultivation, generally creating a greenhouse environment through plastic tunnel technology. Before transplanting, first prepare the land and apply fertilizer; each mu requires about 5000kg of suitable organic fertilizer, along with some other fertilizers. Spread evenly and deep plow, then prepare beds and plant seedlings. Generally, the bed width is about 1 meter. After the preliminary work is done, transplanting can begin. When transplanting, keep the roots with soil, mainly to avoid root damage. The transplanting density is about 30,000 plants per mu, with a plant and row spacing of 15×15cm.

4. Harvesting

After transplanting, strengthen management, paying attention to factors such as temperature, light, and water. The optimal growth temperature for Toona sinensis is 20-25 degrees. It likes light and is not tolerant of shade, but avoids strong light exposure, so pay attention to light duration. On cloudy and rainy days, artificial supplementary lighting can be used, and during strong light, shade promptly. It likes moisture but avoids waterlogging; water promptly during drought, and take drainage and waterlogging prevention measures during rainy seasons. Maintaining this environment will cause Toona sinensis to sprout at a very fast rate, but it can be harvested when the Toona seedlings grow to 15-20 and emerge.
