How to keep pears fresh for storage? Master these methods to store them longer
(1) Raised-bed pit storage method. This is a main storage method used in the Huangxian Changba pear producing area. Before harvesting the pears, choose between-row spaces in the orchard with good ventilation, cool and dry conditions, and a low water table. Build raised beds running north-south, with a bed width of 1.5 m to 2 m; the bed length depends on the storage quantity. The bed surface should be about 10 cm above the ground, slightly higher in the center and slightly lower on both sides, with ridges about 15 cm high built up around the perimeter. Spread a layer of fine sand 5 cm to 10 cm thick on the bed surface. At the four corners of the bed ridges and along the two long sides, drive a wooden post every 750 mm, with a post height of 750

Detailed Explanation of Key Techniques for Jujube Storage and Fresh-keeping
Jujube is one of the fruits unique to China. It is rich in nutrients, containing relatively large amounts of sugar, protein, fat, iron, calcium, phosphorus and other substances. At the same time, its content of vitamin C and cyclic adenosine monophosphate (CAMP) is also very high. In clinical medicine, it has preventive and therapeutic effects on the human body in terms of antioxidation and increasing myocardial nutrition, and is therefore favored by consumers. However, jujube fruit is a fruit that does not store well. At room temperature, it loses its original quality in about 20 days, and at low temperature it can only be stored for 40-60 days. Therefore, the storage and fresh-keeping technology for jujube fruit

Detailed Explanation of Controlled Atmosphere Storage and Preservation Technology for Mushrooms
Mushrooms have a tender and delicate texture, a pure white color, and rich, unique nutrition, making them deeply loved by consumers. However, due to their high water content, tender tissues, and lack of a protective surface structure, both respiration and transpiration are relatively intense, and they are also susceptible to pathogen infection and mechanical damage, leading to rot and deterioration. Under normal temperature and normal air conditions, harvested mushrooms will discolor, deteriorate, and open their caps within 2-3d, reducing their edible quality and commercial value. Given the physiological characteristic that mushrooms are highly prone to aging and browning, at present

Detailed Explanation of Key Points for Storage and Fresh-keeping Techniques of Peaches, Plums and Apricots
Peach, plum and apricot (including cherry) fruits all contain a hard stone and belong to the drupe category of fruits, sharing common characteristics in fruit development and postharvest physiology. It is precisely because the fruit contains a hard stone that a double-S growth curve appears during growth. Peach, plum and apricot fruits have high respiration intensity; all have a respiration peak, so they all belong to the climacteric type of fruit, which determines that they have basically similar storage, transport and fresh-keeping technical measures. However, as tree species and varieties differ, the storage, transport and fresh-keeping techniques adopted also differ. Peaches and plums generally

Detailed Explanation of Key Points of Potato Storage and Fresh-Keeping Technology
The edible part of the potato is the tuber, which contains a large amount of carbohydrates and rich mineral elements. Potatoes are resistant to storage and transportation and can be supplied year-round. They are a popular fresh-eating vegetable and raw material for processed products that help balance market supply during off-peak and peak periods. I. Storage and Characteristics. After harvest, potatoes generally have a dormant period of 2-4 months, and the length of the dormant period varies with different varieties. Late-maturing varieties have a short dormant period, while early-maturing varieties have a long dormant period. Different degrees of maturity also affect the length of the dormant period. The stem of immature potatoes has a longer

Storage Characteristics of Potatoes
Potatoes have a distinct physiological dormancy period after harvest. It generally lasts 2 to 4 months and varies depending on the variety. Generally speaking, late-maturing varieties have a short dormancy period, while early-maturing varieties have a long dormancy period. Different degrees of maturity also lead to different dormancy lengths: immature potato tubers harvested midway through growth have a longer dormancy period than tubers of equal size harvested at maturity. Storage temperature also affects the length of the dormancy period; tubers stored under relatively suitable low-temperature conditions have a longer dormancy period, and low temperatures during the early storage stage are especially beneficial for prolonging dormancy.

Detailed Explanation of Key Points of Potato Storage and Primary Processing Technology
I. Storage Technology 1. Pit storage. Choose a site with high, dry terrain, and dig a trench 0.8-1.5 m wide and 0.9 m deep. Put potatoes pre-stored in a cool place into the trench for storage when freezing is about to occur, spreading the tubers loosely to a thickness of 40-50 cm, placing a bundle of corn stalks every 1 m to make a ventilation tube, with the ventilation tube extending 0.5 m above the ground, covering with a straw curtain, and covering with soil when the temperature drops, with a thickness not less than the frozen soil layer; the top of the trench should be raised. 2. Stack storage method in a ventilated storage warehouse. The potato pile is 1.3-1.7 m high. 2 m wide, and every 2-3 m a

Pre-storage Treatment of Potatoes and Several Practical Storage Methods Explained
1. Pre-storage treatment Pretreating the tubers before storage can inhibit potato sprouting and plays a very good role in ensuring storage results. (1) Sun-drying After harvesting, potato tubers can be spread out in the field to dry briefly, releasing some moisture to facilitate storage and transport. Generally, sun-drying for 4h can significantly reduce the incidence of disease during storage. If sun-drying lasts too long, the tubers will lose water and wilt, which is unfavorable for storage. (2) Pre-storage Potatoes harvested in summer coincide with the hot season; after harvest, the potato tubers should be piled in a cool, ventilated room, cellar or shade shed for pre-storage. For

Key Points of Mushroom Harvesting, Storage and Fresh-keeping Techniques
I. Storage Characteristics and Varieties Mushrooms are rich in amino acids and protein and have a delicious flavor. However, after harvest, mushrooms respire vigorously and at room temperature quickly open their caps, turn brown, develop off-flavors and deteriorate in quality, so they can only be stored for a short time. Dried mushrooms are easy to preserve, but their nutritional value decreases, and delays in processing can cause serious losses. Therefore, measures must be taken after harvest during storage, transport and sale and before processing to prevent a decline in mushroom quality. There are many cultivated varieties of mushrooms, and common ones include oyster mushroom, shiitake, button mushroom, enoki mushroom and phoenix mushroom.

Detailed explanation of key points of mushroom preservation technology, easily extend storage time
Mushroom preservation methods include modified atmosphere preservation, low-temperature preservation, radiation preservation and brine preservation, etc. The methods are: modified atmosphere preservation uses simple modified atmosphere storage, within 3 to 5 days it can keep mushrooms fresh and tender without opening their caps, basically without browning, and with a water loss rate below 1%. At present, breathable plastic film bags are generally used for packaging, maintaining an oxygen concentration of 1% and a carbon dioxide concentration of 10% to 15% inside the bag, which can keep mushrooms white for 4 days with good freshness. Cold storage preservation: low temperature can keep mushrooms fresh and of high quality. During storage and transportation
