The storage of fresh sweet potatoes in the husk is simple and easy. Generally, it will not be rotted during the Spring Festival next year. It is also convenient for feeding, and it can also be used for seed retention. It is suitable for storage in medium and small batches.
method one:
First, the choice of storage sites. In the room choose a lee warm, dry place where moisture is avoided, such as near the corner of the stove.
Second, organize storage. First level the storage site and block the wall holes. Use a clay block to build a 1 to 1.7 m high soil enclosure. The size of the enclosure can be determined by how much the reserve is. The required grain shells are generally about 150 kilograms per 100 kilograms of sweet potato chaff. The chaff is required to be dry and clean, and several straw mats made of straw are to be prepared.
Third, the choice of sweet potato. The sweet potato preserved in the chaff must be free from cracks, broken skin, cuts and lesions, insects, holes, no outcrops, and water stains. storage. After the potato block is selected, first disperse lime in the bottom and around the soil surrounding the soil, and then lay 35 cm thick dry chaff. Surround the grass with a layer of straw mats. Place the sweet potatoes gently. To maintain a certain distance between them, do not touch each other, put a layer of sweet potatoes to cover a layer of chaff, not to see the potato block as the standard, and the hulls slightly pat, straw mats and soil around the use of chaff fill In order to prevent air leakage, potato dumps are generally 1.3 to 1.7 meters high, and the top layer is covered with 35 cm above the chaff and covered with a layer of straw.
Fourth, post-storage management. After storage, just pay attention to waterproof and moisture-proof. After feeding, cover it with chaff at any time, generally it will not cause problems.
Method Two: We must choose sweet potato without damage and disease-free class. Before storage, use carbendazim 500-fold solution or thiophantine-300-fold solution, put it in a water tank or a large pot, and put the sweet potato in a basket or pot, and then dip it evenly in the liquid, remove the stalls. Let it dry for 1 to 2 days to cool the water. In an ordinary room where there is no cold dew and wind is pouring, a layer of waste film is damp-proofed on the ground, and the fence is surrounded by layers in layers. The diameter of the fence is determined by the amount of storage and the size of the space. The bottom layer is first to catch a layer of 10 to 16 cm thick chaff, then a layer of disinfected sweet potato is laid flat, and then a layer of chaff is added. The height of the chaff is increased layer by layer. The thickness of the chaff is not suitable for sweet potato. Between the sweet potatoes and the surrounding seats, there must be 13 to 16 cm intervals, all filled with chaff, in order to facilitate thermal insulation. The height is 1 to 1.7 meters, and the top layer is covered with a layer of chaff. The thickness of the chaff can not be less than 16 cm. If the temperature is too low, cover the straw above and around the perimeter to protect against freezing.
