Pear storage methods are different and require tailored treatment
Master the storage characteristics of pears. Generally, early-maturing varieties do not store well, while mid- and late-maturing varieties and white pear varieties (such as Ya pear) store relatively well. The storage temperature for pears is generally -1°C to 3°C, and the relative humidity is 90% to 95%. Ya pear, Xuehua pear, Ci pear, Changba pear and others are extremely sensitive to carbon dioxide and low oxygen, and are not suitable for controlled atmosphere storage. During storage, be careful to prevent water loss. Pear fruits contain a lot of water, and once they lose water severely during storage, rotten spots, rotten fruit or hollow dried fruit will appear. Therefore, attention should be paid to increasing the humidity in the warehouse

Key points of fresh tea preservation and storage technology: tea leaves are less likely to deteriorate even after long storage
● Vacuum extraction and nitrogen filling preservation. Vacuum extraction and nitrogen filling preservation uses nitrogen to replace the air inside the packaging bag, preventing tea oxidation and thereby achieving the goal of preventing tea aging and deterioration. When green tea is packaged with nitrogen in aluminum foil bags, after 6 months of storage, the vitamin C content can remain above 96%. During the nitrogen filling process, special attention must be paid to the firmness of the packaging bag seal, and insufficient nitrogen filling or gas leakage must be prevented. Before nitrogen filling packaging, first extract the air from the bag to create a vacuum state, then fill it with nitrogen and

Detailed Explanation of Tea Seed Storage Methods and Technical Key Points
Technical measures for storing tea seeds so they do not deteriorate and affect the germination rate. Tea seeds are large seeds, and the seed kernel has a relatively high moisture content. Under ordinary temperature, humidity and air conditions, the moisture content of stored tea seeds has a great influence on their viability. When the moisture content is below 20% or above 50%, the germination rate of tea seeds drops significantly, while the germination rate is highest when the moisture content is around 30%. Therefore, during storage of tea seeds, the moisture content should be kept at around 30%. The suitable storage conditions for tea seeds are a temperature of 5-7°C, a relative humidity of 60-65

How to disinfect a pear storage room? Detailed methods and steps shared
(1) Bleaching powder: Prepare a 10% solution from bleaching powder containing 25%-30% available chlorine. Spray the clear liquid above at a rate of 40mL per cubic meter of storage capacity. Take protective measures when using. After use, the storage room must be ventilated to remove the odor. (2) Formalin: At a ratio of 15mL of formalin per cubic meter of storage capacity, place the formalin with an appropriate amount of potassium permanganate or quicklime, add a little water, and when gas is generated, keep the storage door tightly closed and fumigate for 6-12h. Only after opening the storage and ventilating can the storage room be used.

Key points to note during jujube storage
1. Thoroughly disinfect the storage room with CT storage-room disinfectant. 2. Lower the storage temperature to 0°C within 2 days before loading. 3. Jujubes should be harvested at the white-ripe stage, that is, when the fruit turns from green to white and the surface is slightly tinged with red. 4. Harvest with the fruit stalk attached; jujubes that have been knocked down with sticks must never be put into storage. 5. Jujubes sprayed with hormones such as ripening accelerators before harvest are not suitable for storage. 6. After harvesting, sort the jujube fruit, dip it in CT liquid preservative specially for jujubes, and pre-cool at 0°C while draining until the fruit temperature is 0

Detailed Explanation of Pear Storage Characteristics and Fresh-keeping Techniques
Pear is one of the three major fruits in our country, and its output ranks first among the three major fruits. Its deep-processing volume is limited, and its rot rate is high. In order to extend market supply, storage and fresh-keeping should be done well in combination with its variety characteristics, reducing urban biological waste and providing a guarantee for generating income in the pear industry. I. Biological Characteristics Pears are composed of fruit, core, and seeds. The growth process of pear fruit follows an S-shaped growth curve. In the early stage, cell division and embryo growth are dominant, and volume increases slowly. In the later stage, the fruit grows rapidly. The increase in the 40 to 50 days before harvest is about 10 times the growth amount of the early stage.

Are there other ways to store ginger? An introduction to ginger storage tips
Besides putting ginger in a well, are there other storage methods? Ginger storage techniques: 1) Storage characteristics. Ginger prefers warmth and moisture, is not tolerant of low temperatures, and is prone to cold damage below 10%. Cold-damaged ginger rhizomes rot easily when the temperature rises again; storage temperatures that are too high also cause rot. The suitable temperature is about 15°C, and the relative humidity is 65%. For storage, ginger should be harvested with fully grown rhizomes and must not be exposed to frost in the field. Generally it is put into the cellar for storage immediately after harvest and must not be left in the field overnight. It is best not to harvest on sunny days to avoid excessive sun exposure; ginger harvested in rainy weather or after rain does not store well.

What are the storage techniques for lotus root? Detailed explanation of key methods
For storage, lotus root must be strictly selected: disease-free and undamaged underground stems with a firm texture, thick and plump flesh, and low water content. After harvest, do not wash them; store the whole roots with mud on the surface. They can be stored in shallow pits dug indoors, covered with straw or soil. Alternatively, they can be layered with sand in a storage facility, with the surface covered with 5-10 cm of sand. The covering must not be too thin, otherwise the tubers on the surface layer are prone to dehydration and loss of freshness. If the humidity is too high, they are prone to rooting and mildew rot. According to experiments, in a refrigerated warehouse at 5-7°C (finally, 11°C) and in an ordinary underground cellar (9-14°C in winter, 23-25°C in summer), buried with dry sand

How to store ginger seed stock well? A detailed guide to innovative storage techniques
After harvesting ginger, first spread it out in a ventilated, dry place for a few days; once the surface water on the ginger rhizomes has dried, put them in a storage pit. Before storage, first carry out the following treatments: 1. Disinfect the ginger seed stock by soaking it in a 60% thiophanate-methyl wettable powder solution at 800 times dilution, or soak 600 kg of ginger seed stock using 10 g of sweet potato preservative mixed with 100 jin of water for seed soaking and disinfection; 2. Disinfect and kill insects in the storage pit by spraying the pit with a mixture of 50 g thiophanate-methyl and 30 g kuaishate added to every 15 kg of water. After disinfection is done, place the ginger seed stock into the storage pit, install the exhaust pipe, and seal the pit when the room temperature is below 12°C

Detailed Explanation of Silicon Window Controlled Atmosphere Storage Technology for Garlic Scapes
In the early 1980s, China began large-scale promotion of silicon window controlled atmosphere technology to preserve garlic scapes. It works by embedding a certain area of silicone rubber membrane in a plastic bag to automatically regulate the gas composition inside the bag, achieving the purpose of preservation. It has the characteristics of saving labor, saving time, saving energy, convenient management, stable gas composition, long storage period, low loss, and good quality. The economic benefits are significant, so it was promoted and used on a large scale in a short time. I. Silicon Window Controlled Atmosphere Storage of Garlic Scapes 1. Forms of Silicon Window Use Cold storage silicon window controlled atmosphere has two forms: small packaging fresh-keeping bags and large plastic tents.
