Hawthorn cultivars have different tolerances for storage. Shandong Venus, exposure, and red pods are resistant to storage and can be stored until March to April in the following year, while Liaoning Venus Red Hawthorn can only be stored for about one month. For the storage of the hawthorn should be harvested a few days before the fruit is fully mature, this time the skin completely turned red, the fruit is obvious, the fruit surface has fruit powder and wax, astringency disappeared.
(1) Traditional soil storage. More common are the burial method and the trench method. Burial: Dig a round pit with a diameter of 67 cm and a depth of 1 meter in the shade, and lay a clean river sand with a depth of 16 centimeters on the bottom. Pour the fruit on the sand. Spread a layer of about 34 centimeters thick. Cover a depth of 4 centimeters. Fine sand, and then put the second layer of fruit, the thickness is also about 34 cm, cover 8 cm thick fine sand, later with the thickening of thick sand cover, and finally slightly higher than the ground. Fine sand should have a certain degree of humidity, that is, it is suitable to hold a group but not squeeze water. This method can be stored in April to May of the following year. Trench: It is divided into half underground ditch storage and underground ditch storage. All are required to select a ditch with a depth of 34 cm (semi-ground) or 67 cm (underground) and a width of 67 cm. Ditch and surrounding all the leaves soaked with lime water or other disinfectant solution and dried. The hawthorn fruit is lightly poured and the top is rounded to make the arc tip higher than the ground. The top is 6 cm to 10 cm thick. Leaves, then covered straw mats or straw. Storage period should pay attention to moisture and heat (frozen), gradually increase the thickness of the cover after frost, the temperature within the trench should be maintained at 0 °C ~ 2 °C, the general storage of 5 months to 6 months.
(2) Simple atmosphere storage. Need to have a more appropriate temperature cold storage (cellar) as a guarantee. The production area is generally an improved ventilation or cold storage. Silicon window bag made of 0.08 mm thick polyethylene film, or 0.03 mm to 0.05 mm thick polyethylene film made of ordinary bags, storage period to maintain fruit temperature 0 °C ~ -2 °C, bag humidity of about 90%, through The fruit spontaneously maintains the proper gas composition in the bag. When the oxygen in the bag is less than 2% and the carbon dioxide is less than 5%, the bag should be opened and deflated. If the bag is placed 25:1 (fruit weight: potassium permanganate carrier) The ethylene absorbent as an antistaling agent can further prolong the storage period. This method has less water loss, high hardness, less nutrient loss, good processing and eating quality, and a storage period of up to 6 months.
(3) carbon molecular sieve air conditioning storage. With a thickness of about 0.02 mm high-pressure PVC film bonded into a plastic 2.51.54 meters large account. The fruit is placed in a turnover box or basket into a large plastic account, and carbon molecular sieves are stored in the air. And use the adjustment of opening and closing technology, the gas composition is controlled in the oxygen 3% to 5%, carbon dioxide less than 2% stored at 0 °C ~ 0.5 °C, using this method storage for 7 months, the good fruit rate of 95%.
Same as round type LED Surgical Lamp, the flower type operating lamp also can add camera system, the camera system can choose SD or HD, depends on hospital requirment, even though single dome or double dome, both can add camera system, can choose camera built in or built out. The camera system is Sony brand, we have use it for many years, the system is stable. as recording and teaching is part of Cuntinous Medical Education (C.M.E) within and outside the O.R/ Hospital, our solution is to achieve both. The image resolution of full HD medical grade digital camera can be as high as 1920*1080 pixels.
