Problems solved by technology

Because it is extremely difficult to store sweet potatoes for a long time (more than 3 months) under the current experience and technical conditions, the annual edible period of fresh sweet potatoes is less than four months, which seriously inhibits the consumption of sweet potatoes and the enthusiasm of potato farmers to plant sweet potatoes. The output has stagnated in recent decades (about 100 million tons per year)
[0010] With the rapid advancement of urbanization and industrialization in our country, the grain fields are decreasing year by year, and the pollution of industrialization has degraded the soil quality of some cultivated land. big security risk

example 1

[0035] Example 1: Indoor storage experiment

[0036] Address: The living room on the ninth floor of the living room in the urban area of ​​Wuhan City. There are no temperature and humidity control facilities in the room.

[0037] Sweet potatoes and charcoal are mixed and stored at the above address under natural humidity and air composition conditions (temperature range is 1°C to 26°C). The 100 kg of sweet potatoes are equipped with 6 kg of charcoal, and the distance between the potatoes and the charcoal is less than 30 cm. In addition, no charcoal was used as a control test.

[0038] The experimental results are as follows:

[0044] Example 2: Outdoor storage experiment

[0045] Address: In the hilly area of ​​southern Hubei, after the "Frost's Descent", I bought sweet potatoes and charcoal from the potato farmers' homes, and used two potato cellars abandoned by the potato farmers nearby (because the original sweet potatoes in the potato cellars were rotten and dare not be reused, they have become waste cellar), sweet potatoes and charcoal are mixed and stored in the above-mentioned potato cellar under natural humidity and air component environmental conditions in the kiln, the temperature range in the potato cellar is 8°C-20°C, and 6 kg of charcoal is configured for the 100 kg of sweet potatoes; , The charcoal distance is less than 30 cm, two years of inter-annual experiments in 2012 and 2013 were carried out, and another potato cellar without charcoal was used as a comparative outdoor kiln storage experiment.

[0046] The experimental results are similar to Example 1.

Abstract

The invention belongs to the field of sweet potato storage, and particularly relates to a method for storing sweet potatoes through charcoal functions. The sweet potatoes and wood charcoal / bamboo charcoal are stored mixedly under an air composition environment where the temperature ranges from 1 DEG C to 26 DEG C and the humidity is natural, at least six kilograms of the wood charcoal / bamboo charcoal are allocated to one hundred kilograms of the sweet potatoes, and the distance between the sweet potatoes and the charcoal is smaller than 30 centimeters. The method is used for storing the sweet potatoes, and therefore the sweet potatoes can be stored for more than eight months and have no disease or decay phenomena; in the storage process, neither chemical sterilization disinfectant nor preservative is needed, and special sheds, pits and temperature and humidity regulation facilities are not needed. The wood charcoal for storage can be repeatedly used, storage cost is reduced, and meanwhile the requirement for the environment of sweet potato storage is greatly reduced. The storage process is simplified, the problem that it is difficult to store the sweet potatoes for a long time is solved, and the method is convenient to popularize and makes a great contribution to protection of potential grain strategy safety of our country.

Description

technical field [0001] The invention belongs to the field of sweet potato storage, and in particular relates to a method for storing sweet potatoes by utilizing the charcoal function. Background technique [0002] Sweet potato is also called white potato, sweet potato, sweet potato, sweet potato, sweet potato and other names. It was introduced into my country during the Wanli period of the Ming Dynasty and has a history of more than 400 years. Ipomoea batatas is one of four major food crops (rice, wheat, sweet potato, corn) in my country, and all provinces in China are planted, and annual output is more than 100 million tons. Because it is a dryland crop and has low requirements on the planting environment and planting management, it forms a complementary strategic planting supply situation with other major food crops in terms of arable land, water sources, and food. Sweet potatoes are harvested from tubers and have the following advantages: A. Sweet potatoes are dryland c...
