Problems solved by technology

However, due to the limitations of investment conditions and technical level, the storage methods and conditions of potatoes have not been improved for a long time. In actual production, farmers still store them scatteredly, but due to improper storage techniques, the loss of potatoes reaches 15% to 40%. Thereby, urgently seek new potato storage method

Abstract

The invention provides methods for prolonging the storage period of potatoes by using eupatorium adenophorum spreng, wherein one method is to prolong the storage period of the potatoes by treating the potatoes with a mixture of boiling water extract of the eupatorium adenophorum spreng dry powder, absolute ether Soxhlet extract of the eupatorium adenophorum spreng, absolute ethanol Soxhlet extract of the eupatorium adenophorum spreng, dry powder of the eupatorium adenophorum spreng and sawdust. The method can be operated simply and implemented conveniently, and can effectively inhibit shoots and keep freshness and prolong the storage period of the potatoes.

Description

technical field [0001] The invention relates to the field of potato storage, in particular to a method for prolonging the storage period of potatoes with Eupatorium adenophorum. Background technique [0002] Potato tubers also store nutrients and reproduce offspring. Their water content is as high as 75%. They are large in size, thin in skin, soft in tissue and easy to be bruised, thus causing infection by various germs and molds. Under high temperature and high humidity storage conditions, potato tubers are susceptible to disease and rot, while low temperature (below 0°C) will cause frostbite, and the environment is dry and easy to dehydrate and wilt. Therefore, the requirements for potato storage conditions are very strict. However, due to the limitations of investment conditions and technical level, the storage methods and conditions of potatoes have not been improved for a long time. In actual production, farmers still store them scatteredly, but due to improper storage ...
