Detailed Explanation of Potato Harvesting, Storage and Processing Techniques
I. Timely harvesting. Potatoes intended for storage are best harvested when dry matter accumulation is at its maximum and the tubers are fully mature. Spring potatoes should be harvested in early to mid-June, while autumn potatoes should be harvested in early November and must not be exposed to frost. Whether spring or autumn potatoes, if rain occurs before harvest, harvesting should wait until the soil has dried appropriately. Freshly dug tubers have tender skins and should be left on the ground to air for 1-2 hours, then collected after the potato skin surface has dried slightly. However, they must not be sun-dried for long periods in summer; after harvest they should be promptly stored in a cool, shaded place. During storage, strict selection should be carried out, removing tubers that are diseased, damaged,

What are the storage methods for finished jasmine tea?
The factors affecting quality changes in jasmine tea during storage are mainly temperature, moisture content, oxygen and light. Under general conditions, the most influential is the moisture content of the tea. Next are temperature and oxygen, while light is relatively easy to control. Generally, the moisture content of finished tea when it leaves the factory is best kept below 5%, so that quality changes more slowly. The moisture content of finished jasmine tea when it leaves the factory is mostly close to 8%. Therefore, it is more sensitive to humidity, and the relative humidity of the surrounding environment directly affects the rate at which the tea absorbs moisture. So loose-leaf jasmine tea is best stored in

Detailed Guide to Peach Storage and Preservation Techniques, Extending Peach Storage Life
Some peach varieties ripen during the high-temperature summer season, and their harvest maturity and eating maturity are reached almost simultaneously; in addition, the fruit is soft and juicy with poor storability. However, storability varies greatly among varieties: honey peaches have the worst storability and can only be stored for about 1 week, while late-maturing varieties such as Fei peach, winter peach, and Qingzhou honey peach are relatively more storable. The main problems that easily occur during peach storage include: over-ripening and softening, rot caused by pathogenic bacteria, and chilling injury. The main technical measures adopted in production include: (1) Immediately pre-cool the fruit after harvest: immerse the fruit in 0

Detailed Explanation of Key Techniques for Ventilated Storage of Pears
Ventilated storage of pears is a simple method that uses the natural low temperatures of winter, employing a ventilated storehouse with large day-night temperature differences and heat-insulating and warmth-retaining properties, so that the pears are kept under relatively stable, lower temperature conditions, delaying decay and allowing good storage. The main techniques are: after the pear fruit is harvested, it undergoes pre-storage and injury sorting, is packed into baskets and put into the storehouse, and stacked with ventilation. According to the temperature difference inside and outside the storehouse, windows should be opened or closed promptly and flexibly to regulate the temperature and humidity inside the storehouse, keeping the temperature as close as possible to -3 to 1°C and the relative humidity between 85% and 93%. In severe cold seasons, attention must be paid to preventing freezing, especially for

Preventive disease measures must be taken before fish storage and transport
As the saying goes: "Buy a chicken that can crow, buy a fish that can jump." Yet many fish farmers, after a year of hard work, run into trouble when the time comes to sell adult fish: the fish do not tolerate storage and transport, their whole bodies become congested, and some even die. At this point most farmers think there is a problem with the feed. Indeed, some feed manufacturers, in order to one-sidedly lower the feed conversion ratio and increase fish growth rate, add hormones or hormone-like drugs such as olaquindox to the feed, causing the above phenomena during fish storage and transport. But fish not tolerating storage and transport

Detailed Explanation of Key Points of Lily Bulb Storage and Fresh-Keeping Techniques
I. Choose storage-tolerant varieties. China is the country of origin for lilies, with many cultivated types and varieties. The main ones include Longya lily, Chuan lily, and tiger lily (Lilium lancifolium) and other variants. Among them, the Chuan lily, which is white, flat-spherical, tightly clustered, large, and sweet-tasting, has good quality and stores well. Lilies are generally harvested in early November, mostly by digging out the bulbs with a spade, promptly removing the stems and soil, and cutting off the fibrous roots. Newly dug bulbs must not be exposed to wind and sun in the field, to prevent the outer scales from discoloring and losing water. II. Pre-cool and select the bulbs. After harvest, lilies should be promptly transported to a shady place and evenly

How to Keep Garlic Fresh in Midsummer? The Soil Pit Storage Method
In midsummer, because garlic bulbs are extremely sensitive to temperature and humidity, they will rot and spoil if not stored carefully. Choose a sunny, wind-sheltered spot and dig a soil pit 30 to 40 cm deep; the size can be determined by the amount of garlic bulbs to be stored. After the pit is dug, promptly pour the dried garlic bulbs into the pit, with a thickness of 15 to 20 cm being appropriate, cover them with 15 to 20 cm of soil, then water the soil until it is saturated, and finally cover it tightly with plastic film. Garlic bulbs stored this way will still not spoil after the Qingming Festival of the following year.
