As a high-grade vegetable, Toona sinensis is mainly cultivated in greenhouses, greenhouses and other protected areas. Toona sinensis bud is to cultivate young plants quickly, and to plant them in dwarfing culture in a greenhouse. Generally, seedlings are raised in the greenhouse in early and middle February, and planted in the field in early April. In that year, they can grow into seedlings with a height of 1~ 1.5 meters. After defoliation, they are moved into the greenhouse to maintain a high temperature, and the top buds can germinate in about 40 days. At 20℃, the teeth grow rapidly and can grow for a week.
If the seedlings are raised in the open field, they will be sown in late March, transplanted in summer and autumn, and then cultivated into two-year-old seedlings, which will be moved into the shed for cultivation and bred into Toona sinensis buds. Or, after the seeds are harvested, sow them in the open ditch in late 1 1 month, and cover the soil deeply, and then remove part of the cover soil in early spring, which can improve the emergence rate, early emergence, easy to cultivate into strong seedlings, and then plant them in greenhouses or greenhouses in the season.
In addition, Toona sinensis likes temperature, so it is suitable for cultivation in areas with an average temperature of 8-10℃, and its cold resistance increases with the age of seedlings. One-year-old seedlings directly seeded with seeds may be frozen at about 1 10℃. Toona sinensis likes light and is more resistant to humidity. It is suitable for growing in fertile and humid soil around rivers and houses, and sandy loam is generally better.
