防化员向厚平同志于1990年9月收购稻谷415吨,分别装入房式仓中,并采用稻壳配制剂量10～30ppm的防虫磷(1公斤原药喷拌40～50斤砻糠).撒入先将仓内粮面打平后的粮表层,然后密闭好粮面薄膜.操作方法是按30万斤仓容撒一麻袋(即40～50斤拌药砻糠),50万斤仓容撒两麻袋拌药砻糠.经多次检查表明,仓内害虫与对照仓比较是显著下降,特别对防治稻谷仓内的粉螨和甲虫有效,经筛后检查,仅发现1头/公斤粉螨,而对照仓里粉螨高达30头/公斤以上.为此,我们选用防虫磷砻糠载体粮面层处理,不但其效果好,而且提高了储粮的稳定性.注:是在散仓经磷化铝熏蒸后采取的此项措施.
Chemists took HouTingping’s 415 tons of paddy in September 1990 and placed them in room-type warehouses respectively. The pesticide used 10 to 30 ppm of pest-repellent phosphorus (1 kg of raw material for 40 to 50 kg of bran) ) .Said the first surface of the warehouse after the grain surfaced, and then confined good film noodles .Operation method is according to the warehouse capacity of 300000 kg sprinkle a sack (that is, 40 to 50 pounds of medicine bran), 500 kg Sowing two sacks mixed medicine 砻 bran.After many inspections showed that the positions of pests and control positions is significantly reduced, especially for the control of acarina and beetles within the rice barn effective screening test found only 1 head / kg Powder mites, while the control warehouse powder acaroid up to 30 / kg above .Therefore, we use pest-repellent phosphorus bran carrier grain surface treatment, not only its effect is good, but also improve the stability of stored grain. Bin aluminum phosphide fumigation after taking this measure.
