Why must potatoes and sweet potatoes be stored in separate cellars?
Although sweet potatoes and potatoes are both tuber crops, they are indeed different. Their growing conditions and the suitable temperatures for storing their tubers are clearly different. When storing sweet potatoes, in order to prevent black spot disease, soft rot and other diseases from invading the tubers, the cellar temperature is generally first raised to 34°C-37°C with a relative humidity of around 85%, and kept there for about 4 days, so that the wounds caused to the tubers during digging can heal as quickly as possible and infection can be prevented; in production this is called high-temperature healing. After that, the cellar temperature is generally kept at 10°C-15°C with a relative humidity of

How long is the lifespan of Asarum seeds, and how many years can they be stored?
The lifespan of Asarum seeds is very short. Naturally matured seeds have a very high germination rate, reaching 99%. However, when stored under dry conditions at room temperature for 20 days, the germination rate drops to 81%; at 40 days it drops to 29%; and at 60 days it is only 2%. This shows that when Asarum seeds are stored dry indoors after harvest, the germination rate gradually decreases as the storage period lengthens, and the dry storage period is only 60 days. Because Asarum seeds cannot be stored dry indoors, they should be sown immediately after harvest or treated by sand stratification.

Preventing Sprouting in Stored Potatoes
To prevent potatoes from sprouting during storage, spray 2000-3000 ppm of maleic hydrazide in the field during the late growth stage; alternatively, one week before harvest, spray the whole plant with 500-1000 ppm of 2,4,5-T to extend the dormancy period and storage life; spraying the whole plant with a mixture of 3000 ppm maleic hydrazide and 300 ppm 2,4,5-T 2-3 weeks before harvest gives an even better sprout-prevention effect. In addition, after the potatoes are harvested, spray methyl naphthaleneacetate onto dry soil, then

How to store potatoes? Sharing practical preservation methods
Storage outside the passes: dig a cellar 2-3 m deep outdoors; its length and width depend on the quantity to be stored. Spread a 2 cm thick layer of ash on the cellar floor to disinfect it and remove the peculiar smell of the soil layer inside the cellar. Fix the cellar cover well and put the potatoes down into the cellar. Cover the potatoes with 15 cm of thick moist black soil to keep them moist and protect them from freezing; if the cellar is shallow, cover them with 20-30 cm of moist black soil. The cellar door should not be sealed too early: in early November cover half and leave half open for ventilation. Seal it all by early December. Controlling the temperature well is the key. Plastic bag storage: if in winter

How to Store Mushrooms? Key Points at a Glance
Mushrooms, also known as button mushrooms, double-spore mushrooms, white mushrooms or cultivated mushrooms, belong to the family Agaricaceae, genus Agaricus, and are a cultivated edible fungus vegetable. The fruiting body (composed of the cap, gills, ring and stem) is eaten. They are mainly produced in the region south of the Yangtze River. Harvesting begins 30-40 days after spawning, after which they can be harvested continuously and marketed in stages. They are also cultivated in the Yangtze River basin and northern regions, generally with two harvests for market, in autumn and the following spring.(1) Harvesting requirements: Stop watering before harvest to avoid damaging the mushrooms during picking. The harvest standard should be

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

How to Store and Keep Mushrooms Fresh? A Detailed Guide to Practical Preservation Methods
Mushrooms are best eaten fresh, but since they do not keep well under natural conditions, especially when mushrooms are cultivated on a large scale, storage and preservation can be used to delay @#@136@#@ or to make canned products and other goods for export earnings. Here are several storage and preservation techniques for mushrooms. 1. Cold storage preservation. After the harvested fresh mushrooms are sorted, place them in containers such as baskets, trays or hampers and cover them with multiple layers of damp gauze or burlap. In a cool, shaded place, set out a vat with a small amount of clean water inside, place a wooden rack above the water, set the baskets or hampers containing the fresh mushrooms on the rack, and then seal the mouth of the vat with plastic film. 2.

How to Store and Preserve Peaches? Key Technical Points Explained
Some peach varieties ripen in 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 peaches, winter peaches and Qingzhou honey peaches are more storable. The problems that peaches are prone to during storage include: over-ripening and softening, rot caused by pathogens, and chilling injury. The main technical measures adopted in production are: 1. Immediately pre-cool the fruit after harvest: immerse the fruit in 0.5-1°C
