Sowing method of Chinese toon

1. Seed collection: Toona sinensis blooms in May to June, the fruit matures in October to November, and the fruit matures when it is red-brown. At this time, the fruit can be collected for seed collection. The seeds should be collected from 15~30-year-old tall and healthy mother trees, and the 1000-grain weight and germination rate of the dried seeds should be 15 g and 40~50%.

2. Soak seeds in warm water at 40℃ for about 5 minutes, stir constantly, and then soak them in water at 20~30℃ for 24 hours. After the seeds absorb enough water, remove the seeds and control excess water for germination.

3. Moisturizing and germinating: Chinese toon seeds are spread 3 cm thick and covered with clean cloth. They are placed in an environment of 20~25℃ for moisturizing and germinating. During germination, they are turned 1~2 times a day and washed 2~3 times with clear water at about 25℃. When 30% of seeds germinate, they can be sown.

4. Timely sowing: Toona sinensis shall select sandy soil with flat terrain, sufficient light and good drainage and fertile soil as seedling land, combine soil preparation and fertilization, spread evenly, turn thoroughly, sow the seeds with good bud promotion evenly, and cover 2 cm thick soil.

5. Seedling management: Toona sinensis seeds emerge about 7 days after sowing, and watering is strictly controlled before emergence to prevent soil hardening from affecting emergence. When seedlings emerge and grow 4~6 true leaves, seedlings should be thinned and fixed.

The planting method of Chinese toon

1. Soil preparation and fertilization: sufficient base fertilizer must be applied to the cultivation of Chinese toon in solar greenhouse. The high-quality farm manure shall not be less than 5000 kg, calcium superphosphate shall not be less than 100 kg and urea shall not be less than 25 kg per mu. The soil shall be sown evenly and deeply, and then the seedlings shall be planted in the whole ridge, generally 80~100 cm wide.

2. Planting density: The planting density of Chinese toon is about 30,000 plants per mu, the plant spacing is 15 cm, the row spacing is 15 cm, and the dwarf treatment of seedlings is carried out when the plant height is about 50 cm.

3, temperature management: Toona planting a few days can not be heated, keep the temperature at 1℃~5℃ to facilitate slow seedlings, planting 8~10 days after the cover on the greenhouse, so that the temperature in the greenhouse controlled at 18~24℃ during the day, 12~14℃ at night.

4. Hormone regulation: After planting and slowing down seedlings, use Chuzhibao to treat the upper 4~5 dormant buds of Chinese toon seedlings. Apply 100~120 buds with Chuzhibao for 1 g. The application can make the buds full and the buds strong, and the yield can be increased by 10~20%.

5. Humidity regulation: Toona sinensis seedlings planted in greenhouse should keep high humidity, irrigate water after planting, and then irrigate small water according to the situation. The relative humidity of air should be kept at about 85%. It is better to keep the relative humidity at about 70% during the growth period after germination.

6. Light regulation: Toona sinensis cultivation in sunlight greenhouse should have good light to promote growth, adopt no drip film, keep the shed film clean, combine with pinching at the same time of paclobutrazol treatment, can increase the number of branches.

7. Toona sinensis bud harvesting: Toona sinensis bud grows to 15~ 20cm, and when the coloring is good, harvest should be carried out in the morning and evening. Toona sinensis bud can be harvested once every 7~10 days in the greenhouse for 4~5 times in total. After each bud harvesting, topdressing and watering should be applied.
