高大平房仓整仓富氮低氧气调防治储粮害虫研究

STUDY ON GRAIN INSECTS CONTROL WITH HIGH NITROGEN AND LOW OXGEN STORAGE TECHNOLOGY IN LARGE HORIZONTAL WAREHOUSE

富氮低氧气调储粮是一项无公害、无污染、"零排放"的绿色储粮新技术,是近年来绿色生态储粮技术的主要手段和发展方向。良好的仓房气密性是气调储粮技术得以成功运用的关键,本次研究实验仓房粮面没有采用薄膜压盖密闭处理,直接进行整仓气调作业,并使氮气浓度达到98%以上,维持一定时间,通过对所得实验数据的分析,结果表明整仓富氮低氧气调具有较好的实用性,对锈赤扁谷盗和谷蠹均有明显杀灭效果,而且整仓气调可以解决膜下富氮低氧气调工艺存在的空间防治问题,并减少劳动强度。

High nitrogen and low oxygen technology is one of the green storage technology, is also main way of green and ecological grain storage and the development direction. In the experiments, gastightness is, of so excellent that the heed not be covered by film. The results showed the nitrogen concentration reach to 98% and keep for a certain period of time, It was found that high nitrogen and low oxygen storage technology has good practicability, has obviously better effect in killins The Cryptolestes ferrugineusand Rhyzopertha dominica than traditional approaches. In addition, the proposed approach also solved the space control problem in hish nitorgen and low oxgen storage under film cover approach and then reduced labor intensity.
