1. Mix storage without any use. Some farmers still follow the habit of the past. A tuber with only one pit, the use of potatoes, commodity potatoes, seed potatoes, and processed potatoes, or several different varieties of potatoes, is stored in this cellar. This not only results in the mixture of species and the spread of diseases, affecting species, but also detrimental to the quality of edible potatoes and the value of processed potatoes, thus directly affecting the economic benefits of farmers. During the storage process, only the different requirements of different uses of tubers on storage conditions can meet the intended purpose of storage.
2. Tuber quality cannot be guaranteed. The quality of entry into the cellar requires an individual cellar, dried potato, no rot, and other impurities. However, in the autumn harvest pit, the farmer plans to save time, do not want to use more labor, without drying and picking, so that the soil and tubers mixed, and the wet potato block and the frozen, diseased, injured, rotten pieces of potato into the pit. When entering the pit, the potato was dumped from the pit to the pit, the potato fell, or people trampled in the potato stack, causing the potato block to be injured, which seriously affected the quality of entering the pit. Muddy soil will cause high humidity, poor ventilation, and also bring in various germs, especially Fusarium bacillus dry rot. Diseases, bad potato block into the cellar, directly inoculated a large number of bacteria in the potato heap, becoming the source of bacteria in the pit; the damage of potatoes is easy to make invasive fungi and bacteria, will lead to the spread of disease spread; humidity can not only meet the bacteria breeding Conditions promote the development of diseases, but also tend to cause early tuber germination, affecting quality.
3, improper storage management. Many farmers have the habit of “natural managementâ€, that is, after the cold storage of the cellar, they do not check during storage, do not adjust the temperature and humidity, and do not ventilate and ventilate, so that when the cellar is opened in the spring, there are frozen pits, rotten pits, and heat damage. The phenomenon of germination and black hearts caused major economic losses. Others only pay attention to thermal insulation and fear of freezing. The winter is not ventilated. The large amount of carbon dioxide gas produced by the potato block is not eliminated, so that the normal breathing of the potato block is hindered, and the buds are suffocated, affecting the emergence, and even opening the spring Afterwards, it did not ventilate and ventilate, and people entered the cellar, causing an assault on the cellar.
In modern and semi-modern (when combined with foreign lands) potato storage, due to lack of understanding of the requirements for storage conditions of potatoes, the amount of inventories in storage is too large, the enthalpy is too high, and the air gaps are too small and small to be trapped. The temperature and humidity are not well-understood and create the conditions for the storage disease. In the spring, the temperature of the cellar is too high and the seed potato sprouts prematurely, which reduces the storage quality.
4, storage cellar construction is not scientific. Some sites were improperly located, and the pit was built at a high groundwater level, causing large humidity in the cellar, or even watering; or the potato pits were overcast and facing the tuyere, which was prone to freezing pits. Some cellars are too shallow, the top is covered with thin soil, and the upper part of the potato block is close to the frozen layer, which can easily cause freezing pits. There are no ventilation holes, or the ventilation holes are set unreasonably, so it is impossible to adjust the temperature and humidity in the pits, and it is impossible to pass fresh air, so that the stored potato blocks are damaged.
