对粮堆进行强制的(机械的)和自然的通风,可以利用自然资源,进行降温、降湿,抑制微生物和害虫繁殖生长,以改善储粮条件,是一种经济、有效的储粮新技术。目前,在我市郊县乃至全国各地粮库广为应用。然而,不是所有粮堆可以任意进行强制的或自然的通风的。通风可行性取决于粮堆现有条件和大气特性。不然,要用通风来改善储粮条件是不可能的。粮堆,可以看成有粮粒、草芥杂质、微生物、害虫等为主要生物的生态系统,粮堆 Forced (mechanical) and natural ventilation of food piles can utilize natural resources to cool down, dehumidify and restrain the growth of microorganisms and pests to improve grain storage conditions. It is an economical and effective new technology for grain storage . At present, grain counties are widely used in our suburban counties and even throughout the country. However, not all piles may be arbitrarily forced or naturally ventilated. Ventilation feasibility depends on the current conditions of the poultry and atmospheric characteristics. Otherwise, it is not possible to use ventilation to improve grain storage conditions. Grain piles, can be seen as food grains, straw waste impurities, microorganisms, pests, etc. as the main biological ecosystems, food piles
