Abstract

The invention discloses a grain storage method comprises the following step: placing a fumigation agent below or / and around a grain pile under an environment at room temperature to 40 DEG C, wherein the fumigation agent is a mixture of a thiosulfinate type compound and a sulfo-sulphonate type compound. The grain storage method realizes safe and effective sterilization and disinfection for grains, and has the advantage of green environment friendliness; particularly, one-time treatment of various grains and various germs and moulds under the same fumigation environment can be realized; furthermore, no germ or mould reappears even if the grains subjected to fumigation treatment can be stored for at least half a year or longer in a granary environment or under a transportation condition; meanwhile, the method further has the advantages of simplicity in operation, low cost, large application range to grains, germs and moulds and the like, and has important value and far-reaching significance for safe and long-time storage of the grains.

Description

technical field [0001] The invention relates to a grain storage method and belongs to the technical field of grain preservation. Background technique [0002] In 2014, according to the National Bureau of Statistics, the country's total grain output was 607.099 million tons (1214.2 billion catties), an increase of 5.16 million tons (10.32 billion catties) over 2013, an increase of 0.9%. Ren Zhengxiao, member of the National Committee of the Chinese People's Political Consultative Conference and director of the State Grain Administration, said in an interview with reporters during his participation in a panel discussion of the National Committee of the Chinese People's Political Consultative Conference in May this year: At present, my country's annual grain loss and waste is about 100 billion catties, which is roughly equivalent to the number one grain-producing province in my country. ——The annual grain output of Heilongjiang Province. Food is lost and wasted in every link fr...
