摘要
针对轻钢屋面散装房式仓气密性差、局部发生谷蠹时熏杀难度大的问题,采取局部打探管投药与整仓粮堆上层小布袋埋藏法投药相结合,粮面覆膜密闭,不再进行整仓环流,以保证局部谷蠹发生区域PH3浓度保持在300mL/m3以上25d,可以达到彻底杀死谷蠹的效果。
In view of poor air tightness of light--steel roofing bulk warehouse and the difficulty to fumigate locally occurred Rhizopertha dominica. Applying pesticide by taking probes localy combination with burying small bags at the upper layer of stored grain, sealing grain surface with film, stopping circulation in ware- house, make the PHs concentration be kept over 300 mL/ms for 25 d in local occurenece of Rhizopertha dominica, and then achieved the effect of killing Rhizopertha dominica thoroughly.
