The main reason why the apple harvest cannot be sold is the relative surplus of the apple industry, the difference in market demand and production, the downturn in the world market, and the concentrated listing of late-maturing apple varieties. Proper storage is conducive to adjusting the supply and demand of the fruit market!
How to enter the warehouse for storage should first be picked in time, and the picking time should be prolonged appropriately. When picking, wear gloves and carry the basket with a velvet backing and gently handle it. Secondly, we must cool the fruits before storage and let the fruits fully adapt to the storage.
Before entering the warehouse, smoke the warehouse, clean up the residue in the atmosphere-controlled warehouse, and do the sterilization work well. Such as sulfur, formaldehyde, bleach, ozone, etc. Among them, the sulfur + wood chip combustion method is commonly used. The dosage is 3-58/cubic meter. The flame is extinguished after being burned, and the smoke can be emitted. The sterilization effect is good, but it has a certain decay effect on the metal in the warehouse. Nail awakening (that is, medical lysine water) has a broad spectrum of sterilization and high efficiency, but it is inconvenient to use and improperly used, which is harmful to humans. The product preservation engineering technology research center has developed a new type of professional disinfectant smoke agent for the warehouse. The method of application is: after the warehouse is cleaned, the disinfectant (containing combustion-supporting materials) can be used to emit smoke. The dosage is 3-5 After burning, the warehouse is sealed for more than 4 hours. But before entering the warehouse, you must open the door to ventilate before entering the warehouse. The sanitary status of the warehouse and whether disinfection is required are determined by the health and veterinary personnel. In order to carry out poisoning work, the cold storage plant manager or cold storage design engineer should deploy a special work team and provide tools, work clothes, glasses, gauze bandages, masks or gas masks.
The suitable gas composition of the atmosphere storage inventory technology: oxygen 2%-4%, carbon dioxide 3%-5%, the rest is nitrogen and trace inert gas.
Packaging: For small packaging, polyethylene or non-toxic polyvinyl chloride film with a thickness of 0.06-0.08 mm can be selected and covered on the outside or inside of the fruit basket (box). After the fruit is loaded, it is tightly tied or sealed. The plastic film tent is made of polyvinyl chloride film with a thickness of 0.1-0.25 mm and cut into tents.
After the apple is deposited into the account, it is first evacuated so that the four walls of the account are closely attached to the fruit basket, and then filled with nitrogen to restore the account.
Post-storage management: The oxygen and carbon dioxide concentration in the account should be measured regularly. Carbon dioxide is too high, we must try to eliminate it. The silicon window gas storage (bag) stores 1 ton of apples. At 5-10°C, oxygen is maintained at 2%-4%, carbon dioxide is 3%-5%, and the area of ​​the silicon window should be 0.3-0.6 square meters.

Black tea (dark tea) is named after the black appearance of the finished tea. It is one of the six major tea groups and is a post-fermented tea. The main production areas are Guangxi, Sichuan, Yunnan, Hubei, Hunan, Shaanxi and Anhui. The traditional black tea is made from high maturity black wool tea, which is the main raw material for pressing tightly pressed tea.
The process of making black tea generally includes four steps: killing, kneading, stacking and drying. Black tea is mainly classified as Hunan black tea (Fu tea, Qianliang tea, black brick tea, Tri-tip, etc.), Hubei green brick tea, Sichuan Tibetan tea (border tea), Anhui Gu Yi black tea (An tea), Yunnan black tea (Pu'er tea), Guangxi Liubao tea and Shaanxi black tea (Fu tea) according to geographical distribution.
The yellow powder in black tea is commonly known as golden flower, a beneficial microorganism, the so-called golden flower, is in the processing of raw materials through the flowering of this special procedure, specifically in the black tea bricks to cultivate a kind of coronary aspergillus substance called coronary scattered cystic bacteria, commonly known as the golden flower, observed under the microscope, each individual golden flower is umbrella-shaped clusters, the whole body is golden and eye-catching, ringed into a group, evenly distributed.
