Method for storing rapeseeds by dormancy

Abstract

The invention relates to the technical field of material storage, and in particular relates to a method for storing rapeseeds by dormancy. The method for storing rapeseeds by dormancy comprises the following steps of: firstly, ventilating a material storage bin by a strong ventilating device, wherein the moisture of seeds is less than 7% and the temperature is lower than 18 DEG C; and then, injecting nitrogen to the material storage bin and then, hermetically storing by heat insulation, wherein the bin is isolated from oxygen. According to the method for storing rapeseeds by dormancy provided by the invention, the airing amount of labor of farmers and input of airing fields can be alleviated, the rapeseeds in plants, grain depots and grain purchasing points are prevented from heating, mildewing and brooding, and problems in long-term storage of rapeseeds are solved. Meanwhile, according to the storage method by dormancy, the vitality of seeds is stopped, the consumption is extremely less, and complete nutritional components of rapeseeds are reserved. The method for storing rapeseeds by dormancy provided by the invention is simple and accessible, easy to operate and low in cost, and can be widely applied to the storage of oil plant crops of rapeseed, soybean and the like and crops such as wheat and rice paddy.

Description

technical field [0001] The invention relates to the technical field of material storage, in particular to a method for dormant storage of rapeseed. Background technique [0002] At present, rapeseeds sold on the market are affected by rain and snow during the harvest season, rural labor force, lack of drying sites, rapeseed particles are too small compared with other staple foods, which is not conducive to uniform drying, etc. There is basically no drying, resulting in very uneven moisture content of commercial rapeseed in the market, generally between 8% and 20%. The national standard for safe storage of rapeseed moisture should be below 8%. If the moisture of rapeseed exceeds 8%, when the temperature exceeds 0°C, the vitality of the seeds is in a state of germination. At this time, if they are in the soil, they will germinate. If they are piled together, due to the temperature, the water cannot be discharged smoothly if the temperature exceeds 8°C. It will cause heat, mo...

AI Technical Summary

Problems solved by technology

If the moisture of rapeseed exceeds 8%, when the temperature exceeds 0°C, the vitality of the seeds is in a state of germination. At this time, if they are in the soil, they will germinate. If they are piled together, due to the temperature, the water cannot be discharged smoothly if the temperature exceeds 8°C. It will cause heat, mold, and insects in rapeseed, which will seriously affect the vitality of seeds and the quality and nutrition of finished oil
