从实际观点出发,粮温在10.4℃以下时,几乎无需采用气调或其它技术措施就足以控制米象的发生。低温单因子对米象作用的死亡率是较高的,四周后可达98%RIE(羽化减少率)。粮温15.7℃,二氧化碳浓度为60%二周内米象的 RIE 为99%,三周内 RIE 为100%。而二氧化碳浓度为98%的气控单因子,虽然三周内米象的 RIE 为99%以上,但花的钱很多。而且 From a practical point of view, when the grain temperature is below 10.4 ℃, almost no need to use air conditioning or other technical measures is sufficient to control the occurrence of rice. The single factor of hypothermia has a higher mortality rate on rice, up to 98% RIE after 4 weeks (eclosion reduction rate). Grain temperature 15.7 ℃, carbon dioxide concentration of 60% RIE within two weeks of rice as 99% RIE within three weeks was 100%. The carbon dioxide concentration of 98% of the gas-controlled single-factor, although the RIE within three weeks than 99%, but spent a lot of money. and
