What are the storage methods for damp cotton?
1. Seed cotton should be stored in a warehouse, and the warehouse must be kept dry. Lay clean, dry bricks on the ground, leaving a certain gap between the bricks, with a width of no less than 20 cm, to ensure air circulation; lay bamboo mats or reeds, etc. on the bricks, then pile the cotton on top. 2. The cotton picked back should not be dried directly on the ground; it should be spread on a bamboo bed or a raised bamboo curtain to dry, which is faster and will not mix in three-strand contaminants. When the cotton is dried until the cottonseed makes a crisp crackling sound when bitten with the teeth, the moisture content of the seed cotton is generally around 7.5%, which can satisfy long

Rapid Freezing and Cold Storage Preservation Techniques for Edible Mushrooms
Shiitake mushroom production has flourished across both northern and southern regions of our country in recent years. Since the popularization of bag-cultivated shiitake in Fujian, the provinces of Zhejiang, Henan, Hubei and others have successively developed bag-cultivated shiitake with successful results. Quick-freezing storage of shiitake has become an indispensable and important preservation technique in the production and sales chain. Quick-freezing storage of shiitake is simpler and more convenient than that of button mushrooms. Generally, fresh mushrooms are pre-cooled in ice water, removed and drained, then rapidly placed in an ultra-low temperature freezer at -50 to -60°C for quick freezing, and then placed in a cold storage at -18 to -24°C for storage, entering consumers' homes through the "cold chain" system.

Processing Methods and Storage Tips for Scorpions
In the process of artificial scorpion farming, timely harvesting, processing, storage and selling are important steps for making full use of space, saving feed, speeding up capital turnover and increasing added value; this work should be carried out 7 days before pregnant scorpions give birth, by keeping strong pregnant scorpions and high-quality breeding scorpions, and harvesting and processing the remaining mated male scorpions, female scorpions that have given birth for more than 3 years, and some scorpions with missing limbs, disease or weakness as commercial scorpions. 1 Processing methods 1.1 Processing of "salted whole scorpions" Before processing, first put the scorpions into cold

The Correct Method for Peach Harvesting and Storage
I. Harvesting (1) Harvesting period. It should be determined based on comprehensive factors such as the variety characteristics of the fruit, its use, the distance to the sales location, the means of transport and the storage conditions. Generally, for local fresh sale, it is best to harvest when the fruit is 80-90% ripe; for long-distance transport, it can be harvested at 70-80% ripe. Hard peaches and non-melting peaches can be harvested somewhat later, while melting peaches, especially soft-melting peaches, must be harvested somewhat earlier to avoid losses during transport. Processing peaches should be harvested at 80-90% ripe, as the processed product then has a good flavor. However, if it is a melting variety, in order to reduce losses from splitting the peach and other handling during processing,

Research on Storage and Fresh-keeping Techniques for Jujube Fruit
Jujube is one of the fruit trees unique to China, with a cultivation history of over 2,000 years. The jujube tree is cold-resistant, drought-resistant and tolerant of poor soil, with strong adaptability, and is known as the "ironclad crop." Jujube fruit is rich in nutrients, containing more than twice the sugar of ordinary fruits as well as relatively large amounts of protein, fat, iron, phosphorus, calcium and other substances, and has high nutritional value and dietary therapy functions. Domestic research on fresh jujube storage and its postharvest physiology began in 1980, and studies and explorations have been carried out on the postharvest physiology and storage of jujube, with a great deal of work done on physiological and biochemical mechanisms.

What are the methods for preserving garlic bulbs? Practical storage tips to teach you a few tricks
Garlic bulbs do not store well. Even in a dry, ventilated environment, after 100 days of storage they will sprout, shrivel and become moldy, affecting the planting quality for the following year. Therefore, mastering the storage techniques for garlic after harvest is extremely important. Here four garlic bulb storage and preservation techniques are specially introduced: 1. Hanging storage method. After harvest, the fresh garlic bulbs are first sun-dried for 2-3 days; when the leaves become soft, tie the garlic into bunches of 8-10 bulbs each, then hang them neatly under a shade shed or eaves to air-dry naturally. During the hanging storage period, exposure to the sun should be avoided in summer and autumn, and in winter the garlic bulbs should be moved into a ventilated room for storage to avoid moisture and freezing.

Key Points and Methods for Ginger Storage
1. Storage characteristics: Ginger prefers warmth and moisture and is not tolerant of low temperatures; it is prone to chilling injury below 10°C. Chilled ginger rhizomes rot easily when the temperature rises, and rotting is also easy when the storage temperature is too high. The suitable temperature is about 15°C, and the relative humidity is 65%. Ginger for storage should be harvested when the rhizomes are fully grown and must not be exposed to frost in the field. Generally, it is stored in cellars immediately after harvest and should not be left overnight in the field. It is best not to harvest on sunny days to avoid excessive sun exposure; ginger harvested on rainy days or after rain does not store well. 2. Ginger storage methods: pit burial method and well cellar method: where the soil layer is deep,

Many Methods for Preserving Edible Mushrooms: Master the Techniques to Extend Storage Life
Salt preservation: Freshly harvested oyster mushrooms, Phoenix-tail mushrooms and the like, after being cleaned up, are soaked in 0.6% salt water for about 10 minutes, then taken out, drained and stored in plastic bags, keeping fresh for 5-8 days. Rice-water film preservation: Add 1% soda ash or 5% baking soda to rice water, stir well, and cool to room temperature. Soak freshly picked mushrooms in the rice water, take them out after 5 minutes, and dry them in a cool, dry place; by then a thin film of rice water will form on the surface of the mushrooms, which can isolate air, and the mushrooms can generally keep fresh for 2-3 days.

Key Technical Points for Seed Collection, Storage and Seedling Cultivation of Korean Pine
1. Seed Collection and Processing. Korean pine is a monoecious species with unisexual flowers; its flowering period is in mid-to-late June, and it takes 15 months from flowering to cone maturity. The seed collection period for Korean pine can last up to 4 months; in the early stage, cones can be picked or knocked down from the trees, and in the later stage, cones can be picked up from the snow. After collection, the cones are spread out to sun-dry or air-dry in the shade for several days; when the scales slightly open, they can be processed by beating with a stick by hand. The seed extraction rate of cones from natural forests is 13%-14%, while that of cones from plantations can reach 30%, with a 1000-seed weight of 520 grams. In seed collection work
