Detailed Explanation of Key Points for Potato Storage and Fresh-Keeping Techniques

Potatoes are a vegetable with a dormancy period. In summer, heap storage does not require refrigeration or cooling, but it is necessary to prevent heat buildup in the heap. The specific method is: pile undamaged, high-quality tubers in a well-ventilated room or ventilated storage warehouse, with a heap height not exceeding 0.5 m. To prevent the tubers in the heap from overheating, set up a ventilation tube every 1 m. If they are packed in baskets and stacked into piles, it is best to stack them in a "#" shape to facilitate ventilation. During storage, regularly turn and inspect them, promptly remove infected tubers, and prevent the spread of pathogens. To prevent the tubers from sprouting during storage, a certain amount of methyl naphthaleneacetate can be sprinkled into the heap: for every 500 kg of tubers, use 150 g of methyl naphthaleneacetate, mix it evenly with 20 kg of fine soil, and spread it evenly over the tubers. The sprout-inhibiting effect is obvious.
