Toona sinensis seedling is a woody vegetable with high nutritional value, which is mostly cultivated in the open field. Dwarfing and close planting technology is widely used. This method can be planted directly or transplanted. Let's take a look at several key conditions of Toona sinensis seedling cultivation technology.

1. Soil conditions of Toona sinensis seedlings

Toona sinensis likes deep and fertile calcareous soil. It grows most luxuriantly on green sandy soil and mixed soil.

2. Lighting conditions of Toona sinensis seedling.

Toona sinensis trees like and avoid light. Being fond of light means that sufficient light can get higher yield. Avoiding light means that the trunk of Toona sinensis is used to direct sunlight for a long time, which is prone to trunk deviation and sunburn.

3. What temperature conditions do Toona sinensis seedlings need?

General temperature regulation should control the following periods:

① After film mulching, the indoor temperature of the shed should be controlled at 15 ~ 25℃ during the day, and it should be ventilated and cooled in time when it is higher than 25℃. The temperature at night should be controlled at 10 ~ 15 degrees Celsius, and when it is lower than 10 degrees Celsius, cover it with grass.

② After about 15 days, the temperature of Toona sinensis buds should be controlled at 25 ~ 30℃ during the day and at 13 ~ 17℃ at night, and the lowest temperature should not be lower than 7℃.

③ After 20 ~ 25 days, the bud length can reach about 20 cm, and the suitable temperature for bud picking is 18 ~ 25 degrees Celsius.

4. Humidity conditions required by Toona sinensis

After Toona sinensis seedling, the root system is destroyed, and the water absorption capacity is poor. It is necessary to maintain high soil humidity and air humidity after transplanting indoors. After germination, the relative humidity of the air is about 70%. If the humidity is too high, it should be ventilated and dehumidified in time.

5. Method of harvesting Toona sinensis buds

On the day before harvest, if the light is strong, cover with grass to shade and soften, and the light is weak on the day of harvest. So picking buds should be done in the morning and evening.

Generally, you can harvest 1 time of Toona sinensis shoots in greenhouse every 10 day. Appropriate topdressing and watering after harvest to promote growth. Toona sinensis buds planted around the Spring Festival should be carefully sorted and bundled after harvest, generally 50- 100g per tree, and packed in plastic bags to prevent dehydration and cooking and improve the quality of seedlings.
