高水分稻谷分步降水试验

Control of Stored Grain Protectants Osthole Effect on Stored Grain Insects

将新收获的水分高低不均的稻谷,在未采用机械烘干的情况下,通过分布采取场地晾晒、罩棚内通风降水和仓内就仓干燥3个降水措施,可以将水分高低不均的稻谷水分降至14.5%～15.5%,降水效果较理想。本试验为直接收购高水分粮提供了切实可行的技术支撑,达到了降水、消除储粮安全隐患的目的。

To evaluate the control effects of osthole in silo and squat silo, using 50g/t grain bulk surface 30-50 cm mixed dose of the method of grain storage insects control effect test of maize.The results showed that： osthole can effectively control Sitophilus zeamais （Motschulsky ）, Cryptolestes ferrugine us （ Stephens ） and Plodia interpunctella （Htibner ） within the grain bulk occurrence of insects in stored grain has good control effect.Humidity of the warehouse, such as grain temperature and food quality had no influence, to achieve a certain economic benefits, to control stored grain insects requirements.
