The Chinese Toon scientific name is Toona sinensis (A. juss) Roem. Amaranthidae is a perennial deciduous tree with edible tree buds and seed buds. First, the choice of varieties Shannon has been scattered naturally since ancient times. At present, there is no certain variety. The color and aroma of shoots are divided into various regions. There are red tortoise, brown tortoise, red leafhopper, red bud, green oil, black oil, and red oil.椿, Qingyou, 薹椿, etc According to the experience of various regions, cultivate pods of citrons, and use red pods with red, bright, strong odor, sweet taste, crisp juicy and less slag, such as red oil oysters in Taihe County of Anhui Province, and red in Shandong Yishui City. Taro, as well as the red citron in Jiaozuo, Henan. The seeds collected from trees aged 7-10 years have strong vitality and high yield of sprouts. Second, sowing should use new seeding. Because the seeds of citrons are high in fat and have a short life span. Usually one year or so after the seeds are completely lost their ability to germinate, so when buying seeds must pay attention to, the new mining seeds are bright red and yellow, seed coat dull, seed yellow-white, scent, and long-storing seeds, the seed coat It is black-red, shiny, oily, and fragrance-free. The 1000-grain weight of the seed of Toona sinensis is about 11 grams. If it is less than 8 grams, it is not full of seeds and should not be used. Before sowing, the seeds should be removed from the impurities, wolfberry grains, species wings, etc., and then soaked in warm water at 55 °C, soaking when stirring constantly to the water temperature dropped to about 30 °C, change for fresh water and then soaked for 12 hours, with Place the gauze wrapped at 23°C to germinate. Rinse 1~2 times daily with warm water until the seed buds are 1–2 mm long. The culturing substrate can be blended with perlite, perlite, peat moss, and clean river sand, spread evenly over the pots, about 2.5 cm thick, and wetted with water. It is even more convenient to use two layers of highly absorbent straw or white cotton cloth on the bottom of the cultivation pot to broadcast the germinated seeds. The cultivation containers are optional, but they must be disinfected and washed. The best use of three-dimensional cultivation of large-scale production, set up shelves, with a unified seedling plate, you can buy ready-made lightweight plastic pots. It is generally 60 cm long, 5 cm high, and 24 cm wide. It is compatible with the specifications of the stand so that it can be stacked. The stand should not be too tall. There are 1.6 meters or so, each with 4 to 5 layers and a spacing of 40 to 45 centimeters. For ease of operation. With the plastic pots of the above specifications, the seeding rate is 40-50 g/pot, 240-300 g/m3. Perlite used as a substrate, still covered with perlite after sowing, thickness of about 1.5 cm, immediately after covering the water; with grass or cloth pad bottom, direct sowing. After sowing, stack the plates for about 5 days and wait until 0.5-1 cm before placing them on the cultivation rack. 3. About five days after sowing, the seed buds extend out of the substrate and must be sprayed in a timely manner to keep the relative humidity of the air at about 80%. The conditional facilities can install micro-spraying equipment to achieve uniform and labor-saving purposes to speed up the sprouting. Grow and get a softer product. Spray water to use a fine hole watering can to prevent the buds shoot down, the amount of water spray in the seedling plate is not the degree of accumulation of water. (1) Temperature. The temperature of the cultivation room should be 20~30°C during the daytime, and the maximum temperature should not exceed 28°C and 16°C at night. (2) Light. To protect from light and shade, adjust the seedling plate position every 1 to 2 days so that the growth is even. 4. Harvesting can be harvested 15 to 18 days after sowing when the temperature and humidity are suitable. Qualified products have a hypocotyl length of 10 cm or more, cotyledons fully expanded, no true leaves, no lignification, no rot, rotten species and diseases, and strong aromas. When harvested, it should be pulled up and cleaned, and it should be packaged or cut into live boxes for product production. The general yield is about 10 times the seed weight.
