小麦热入仓防治玉米象效果研究

摘要

小麦热入仓储藏是小麦经暴晒后趁热入仓储藏，以达到防治储粮害虫的一种农户常用储粮方法，目前对小麦热入仓后防治害虫的关键因素研究还较少。在河南省临颍县农户家开展小麦热入缸储藏防治害虫实验，结果表明：小麦暴晒热入仓可以有效杀灭玉米象的卵及幼虫，对小麦品质指标基本没有造成影响。监测数据显示仓内氧气浓度基本没有变化，粮温偏高并持续一段时间，因此，可以说明小麦热入仓储粮方法杀死害虫的主要因素是温度。%Wheat was loaded into granary for storage right after being heated in order to prevent pests, which is one of the frequently used methods in farmers.But at present the key factors of the method is unclear.The experiment of loading heated wheat in vat to check the effect of the method was carried out in a farmer in Henan province.The result showed:wheat was loaded into a vat after being heated could effectively kill maize weevil eggs and larvae,but little impact on wheat quality indicators.Monitoring data showed that oxygen concentration was almost constant and the wheat temperature was on the high side and continued for a period of time.Therefore,temperature is the main factor by the method.
