It is a time when the wheat harvest season is coming. If it gets wet, it will cause the wheat to germinate and it will cause serious reduction in production. For this reason, in the event of wheat harvesting in the rain, it is necessary to adopt effective methods to prevent buds and molds on wet wheat. The closed anoxic method lays a layer of rice bran or wheat shell on the dry ground in the room. Then lay a layer of plastic film on it and then pile the wet wheat on the film. About 500 kilograms into a pile, stacked into a cone or rectangular can be; piled on the cover without damage to the plastic film, surrounded by tightening, and compaction with soil sealing, so that natural wet wheat wetlands to inhibit microbial activity. Vinegar spraying method will remove wet wheat leaves, shells and other impurities, stacked in a dry and ventilated place; then according to every 100 kg of wet wheat with 0.5 kg of vinegar to spray, spray while stirring evenly, continue spraying the end of the heap, can be greatly Delayed germination time. The propionic acid treatment method moves the wet wheat to a dry, ventilated place in the house. The proportion of 0.1 kg of propionic acid per 100 kg of wet wheat is sprayed evenly on the wet wheat with a sprayer. Mixing salt and alum in proper amount of salt and alum into wet wheat can not only absorb the moisture of wet wheat, but also play a bactericidal action. The quantity to be mixed is 1.5-2 kg of salt and 0.5 kg of alum for every 100 kg of wet wheat. After mixing in, place them in a ventilated room and seal them with plastic film. In addition to mixed salt, alum, bleaching powder can also be added, 0.1 kg per 100 kg wet wheat. The method of precipitating and dehumidifying the air is to stack wet wheat on a terrace where there is no leakage of wheat and can be ventilated. The blower, exhaust fan and electric fan are used to wind the wet wheat. The thickness of the wheat stack should not exceed 30 cm. Each blow 1-2 hours. China Agricultural Network Editor
