Toona sinensis cultivation techniques
The fragrant sprouts are green, fresh and delicious, rich and fragrant, nutrient-rich, and have the reputation of plant protein, and are well received by consumers. First, production sites and facilities The suitable temperature for the seed germination of Toona sinensis is 20°C-23°C, the growth is stopped above 35°C, and it grows slowly below 12°C. The spring and autumn seasons should be produced in greenhouses or other idle houses. In the winter, they should be produced in greenhouses, basements and other idle houses. The conditions of light scattering in the middle and later stages are necessary. Using a three-dimensional matrix seedling cultivation method, the cultivation frame can be made of angle iron, steel, bamboo, wood and other materials. The height is 1.6-2 meters, divided into 4-5 layers with a spacing of 40-50 centimeters. It is best to use flat-bottomed perforated plastic seedling trays that are 60 cm long, 24 cm wide and 4-5 cm high. In addition, watering hoses, nozzles, soaking ponds or plastic basins are also required. Second, choose a good species Should choose rich flavor, crisp and juicy, fiber-less varieties, the current good quality red oil, red oysters and so on. Stored in sacks or bags, and stored in ventilated, dry, dark, low temperature conditions, the service life can be extended. The fresh seeds are bright red, the seed coats are dull and scented. Sprouts should use seeds with a germination rate of 90% and a grain weight of 10 grams or more, with about 50 grams of seeds per plate. Third, cultivation techniques 1. Soak germination. Seeds remove impurities, pods, go to species wings, soaking in warm water at 55°C, stirring constantly, until the water temperature drops to about 30°C. After soaking for 12 hours, remove and rinse. Leach the water on the surface of the seed and put it in a thermostatic place at 23°C. Embryo, wrapped in beanbag cloth, thickness 5-6 cm, washed with warm water once or twice a day, the seed bud grows to 1 - Seed when it is 2mm. 2. Sow. After pre-sterilizing the seedling dish or container, the bottom layer is covered with a layer of paper, and then a layer of 2.5 cm thick wetted perlite (with 50% water) is laid to evenly spread the seeds of the buds onto the substrate. About 50 grams per plate, such as low germination rate to increase the amount of seed. After sowing, cover 1.5 cm thick perlite and spray immediately after covering. It is also possible to directly sow the two layers of cotton cloth at the bottom of the tray, but stack the plates for about 5 days until the buds grow to 0.5-1 cm and then put them on the cultivation rack. 3. Management. About 5 days after sowing shoots out of the substrate, should be sprayed in a timely manner, to maintain the relative humidity of about 80%, can be used soft water pipe mounted sprinkler watering, spray can also be sprayed, to be uniform and amount, so as not to impact sprout, not within the plate Water is the standard. Temperature control at 20 °C - 23 °C is appropriate, to block the sun, adjust the seedling plate position every 1-2 days, in order to facilitate uniform growth. When the shoots grow 2-3 cm long, see light growth, and keep ventilating every day. Fourth, harvest Under suitable conditions of temperature and humidity, it can be harvested about 18 days after sowing. Qualified product standards: The hypocotyls of shoots are more than 10 cm in length, the cotyledons are fully expanded, new leaves are not produced, and they are fresh, clean, free from rot and disease, and have a strong aroma. Take root and pull it out to clean it and put it on the market.
