The living buds of Toona sinensis were soillessly cultured without using any matrix. Compared with common methods, the test was more convenient. The production cycle is short, only 15 days to 20 days grow at suitable temperature. With high yield and good economic benefits, 1 kg of dried seeds can produce 8 kg - 9 kg of seeds. No chemical fertilizers or pesticides are used during production, and it is a pollution-free vegetable. First, the production technology points 1. Seed germination rate of the seeds every other year is extremely low, requiring production and use of species must be the new species of the year. 2. Soak the seeds and remove the seeds, remove the impurities, and soak the seeds with warm water at 55Â°C. Stir the mixture for 12 hours to allow the seeds to absorb enough water. 3. Germinate The soaked seeds were removed, drained, and placed on a plastic tray covered with wet newspapers, with a thickness of 2 cm to 3 cm. The dish was germinated at a temperature of 20Â°C to 25Â°C. During the germination process, it must be turned frequently and at least twice a day to make the seeds germinate. 4. After 4 days and 5 days of germination in sub-platform, when the shoots are about 1 cm long, the seeds should be hand-splitting and spread evenly on a plastic tray covered with wet newspapers. It is advisable to sprinkle the seeds with the bottom of the dish, and then spray. Water, It is better to have a small amount of water on paper. 5. Daily management should pay attention to regular time during this period, spray, spray 2 times -3 times a day, water do not submerge the seeds, the temperature is maintained at about 25 Â°C during the day, about 10 Â°C at night, pay attention to moisture, so 5 days -6 days after the citron The embryos started to arch and grew from 5 days to 6 days to a height of about 10 cm. The cotyledons were ready to eat when fully flattened. From soaking to growing, it takes 15 days to 20 days at 10Â°C-25Â°C. Second, the production methods and utensils 1. Winter and spring can be produced indoors or in greenhouses, summer high temperature season to stop production, the optimum temperature for the growth of Toona sinensis buds is 10 Â°C -25 Â°C, when cultivated first to meet the temperature requirements. 2. In order to save space, three-dimensional cultivation can be used. The cultivation frame is made of angle iron, steel bars, bamboo wood, etc. The cultivation is carried out in 3 layers - 5 layers, each layer spacing is 30 cm - 40 cm. For the convenience of operation, the height is not more than 1.6 meters. It is appropriate. If it is produced in small quantities indoors, the plastic tray can be picked up and cultivated. 3. Seedling trays are made of lightweight plastic trays with mesh at the bottom. The size is 30 cm in length, 25 cm in width and 5 cm in height. It is convenient to operate. 4. Water spray devices, typically using a hand-held watering can or sprayer. 5. Moisturizing Start with germination, using a plastic pan plastic bag or cover plastic film moisturizing. 6. During the early stage of production, shading is required. When the seed bud grows to 8 cm to 9 cm, see the light again and then dry it for 1 day to 2 days to make it green. III. Characteristics of Toona sinensis Buds Toona sinensis buds are more tender and tender than those of sassafras tree buds. They have a richer flavor and green color. After cleaning, they can be consumed by roots. The trial sale is welcomed by hotels, restaurants and families.
