Toon bud
Citron is a unique woody special dish in China. Using seeds to quickly produce sprouts is a scientific research result promoted in recent years. The citron buds are delicious in color, crisp and juicy, rich in aroma, sweet and delicious, and rich in nutrients. You can mix it with tofu, stir fry eggs, and make salads.
The most suitable temperature for toona sinensis buds is 20°C-23°C, and the highest temperature is not more than 30°C and the lowest is 16°C. Scattered light growth conditions are required, and robust conditions are required for more humid conditions.
Variety selection: It is recommended to use bud red, bright, rich aroma, sweet, juicy and juicy slag. At present, the best quality is Taihu County, Anhui Province, the "red oil", Yunnan, "red oil," Henan Jiaozuo, "Hong Fragrance", Shandong Surabaya, "Hong Fragrance" quality is also very good. The use of 7-10 years of ageing seed yield is high. As the seeds are rich in oil and have a short life span, which is generally only about half a year, they should be stored in air-breathable sacks and stored in ventilated, dry and dark conditions. It is best to store them at minus 15°C in cold storage. Can be extended. The new seeds are red and yellow, the seed coat is dull, and the seeds are yellowish white and scented. Seeds are dark red, shiny, oily, and fragrance-free. The seed weight of camphor seeds is about 11 grams. If it is less than 8 grams, it is not full. Sprouts should use seeds with a grain weight of 10 grams or more and a germination rate of more than 85%.
Production methods: Toona sinensis buds can be produced in greenhouses, warehouses, basements and other houses with suitable temperatures. In order to save land, improve the utilization rate of protection facilities, and facilitate standard management, a three-dimensional matrix tray planting method should be adopted. The cultivation frame can be made of angle iron, steel bar, bamboo and wood materials, and the height is about 1.6 meters so as to facilitate the operation. Each frame has 4 to 5 layers and each layer has a spacing of 40 to 45 centimeters. In order to reduce the load on the cultivation racks, lightweight plastic discs should be selected. Considering the convenience of management and harvesting, specifications should be moderate, 60 cm long, 25 cm wide and 5 cm high. The matrix is ​​best made of perlite. It can be blended with peat and washed sand. It can also be used as a paper or white cloth with strong water absorption on the second layer of the seedling plate, but the water spray should be strengthened. Other methods and other containers can also be produced.
Main cultivation techniques
(1) Immersion seed germination: Seeds remove impurities, peptone, go to species wing, soak in warm water at 55°C, and start stirring constantly, until the water temperature drops to about 30°C. After soaking for 12 hours, remove and rinse. Leach the water on the seed surface and put it on a constant temperature of 23°C to germinate. It is best packed in beanbag cloth. The seed thickness is 5-6 cm. Every day, it is washed with warm water for 1-2 times. Buds can be sown when they are 1-2 mm long.
(2) Seeding: Wash seedlings or containers in advance and then rinse them. The bottom layer is covered with a layer of paper, and then a layer of perlite with a thickness of about 2.5 cm is mixed (the volume of perlite and water is 2:1). Then, the seeds of the buds were evenly sowed on the substrate, and the germination rate was about 90%. The seed sowing rate per dish was 40 grams. About 240 grams per square meter. After sowing, it covers the perlite with a thickness of about 1.5 cm. It is sprayed immediately after covering, and it can also be directly covered with pearlite. If sowing directly with cloth or paper, stack the plate for 5 days until the bud grows to 0.5-1 cm and then put it on the cultivation frame.
(3) Management: About 5 days after sowing, shoots stick out of the substrate. Water should be sprayed in a timely manner to keep the relative humidity of the air at about 80%. The growth should be accelerated, and the quality should be soft and tender. It is advisable to install micro-spraying equipment in the conditional facilities. In order to achieve the purpose of uniform labor. Can also be used to sprinkle metal sprinklers or watering can spray, pay attention not to shoot sprouts, seedlings plate is not the standard for water. Temperature control at 20 °C - 23 °C is appropriate; pay attention to shade and light. Adjust the position of the seedling plate every 1-2 days to facilitate even growth.
(4) Harvesting: Under suitable conditions of temperature and humidity, 15-18 days after sowing can be harvested. Qualified commodity standards: The hypocotyls of shoots were more than 10 cm in length, and the cotyledons were fully unfolded, not lignified, with no heart leaves, no rotten roots, rotten species and diseases, and strong aromas. After being cleaned up, the packaging is put on the market, and it is also possible to cut live packaging. Generally about 360 grams per plate can be produced, 2400 grams per square meter, biological production is about 10 times the weight of the seed.
