At present, it is the peak season for the harvest of toona sinensis, which is a high-end food that people like to eat. This kind of vegetable is very rich in nutritive value, contains many vitamins and amino acids that the human body needs. In order to improve the product quality of toona sinensis buds, solve the problem of easy defoliation and discoloration and after-sweet taste after harvesting, the market supply period of toona sinensis buds is increased, and the economic benefits are improved. The following methods can be used to preserve freshness:
1. The basement is piled in the basement or in a cool and ventilated place. Sprinkle water on the ground first, and then stack the torreya on the mat. The thickness is about 10cm. Cover it with fresh grass or plastic film and keep it moist for 5-7 days. It can be used during budding seasons to disperse peaks and balance the supply market.
2. Dipping and immersing storage method: The bases of squid sprouts of equal size are tied together and put into small pots, erected in pots or pools, added with clean water, immersed for about 3 to 5 centimeters, soaked for 1 day and night, and then put into baskets to save 1 week.
3. The plastic bag sealing method uses a plastic bag of 40 cm x 50 cm or 35 cm x 25 cm, which is bundled into small bags of fresh buds and sealed for 10 to 20 days. Midway can open bag air 1 time.
4. The quick-freezing storage method uses hot water to flow and scald, and then quickly freezes at a temperature of minus 15-20°C, and the temperature is kept at minus 10-15°C for storage. When thawing, sprinkle with 5~10% citric acid to protect the color and fragrance from corruption.
5. For frozen storage, bundle the toad buds into small ones, spray the fluorspar that absorbs the garlic oil or directly with 0.01% hydrogen-based purine preservatives, and dry them in plastic bags (thickness of 0.7 mm or more in plastic bags). Close the bag mouth, set the cold storage, the temperature is maintained between -1 ~ 0 °C. Every 10 to 15 days, you can open a bag and change the air once to keep the oxygen content in the bag no less than 2%, and the content of carbon dioxide does not exceed 5%. The shelf life can be 55 to 60 days. Large-scale intensive production must do a good job in cold storage construction.

A seedbed or seedling bed is the local soil environment in which seeds are planted. Often it comprises not only the soil but also a specially prepared cold frame, hotbed or raised bed used to grow the seedlings in a controlled environment into larger young plants before transplanting them into a garden or field. A seedling bed is used to increase the number of seeds that germinate.
