我市干阳一公里粮库地下仓5号库储存小麦于12月因谷蠹繁殖造成发热,发热部位最高为42℃。采用PH_3、CO_2混合熏蒸后,害虫全部杀死,粮温从42℃逐步降至23℃左右,至次年4月未发现活虫,取得了显著的杀虫、降温效果。 1 试验材料及方法 1.1 试验仓与试验粮 试验仓为干阳一公里粮库5号喇叭形地下仓,储存小麦为1997年1O月入库,共计180万kg。小麦平均水分11％,杂质O.7％,粮堆高度17m。发热部位位于粮面西北部,面积约为20m~2,上层距粮面
The city’s one kilometer dry grain warehouse underground warehouse on the 5th storage of wheat in December due to the death of Grus grus caused by fever, fever, the highest part of 42 ℃. After fumigation with PH_3 and CO_2, all the pests were killed, the temperature of the grain gradually dropped from 42 ℃ to about 23 ℃, and no live insects were found in April of the following year. Significant insecticidal and cooling effects were achieved. 1 Test Materials and Methods 1.1 Test Bureaus and Experimental Grain The test bureaus were the trumpet-shaped underground silos of Grain Depot No. 1 at a kilometer of dry Yang. The stored wheat was stored for 10 months in 1997 with a total amount of 1.8 million kg. Wheat average moisture 11%, O.7% impurities, grain heap height 17m. Fever is located in the northwest grain surface, an area of about 20m ~ 2, the upper away from the grain surface
