1.暴晒杀虫暴晒是以太阳辐射热破坏虫体组织,使害虫致死,同时还具有防潮、防霉的作用。小麦、玉米、豌豆、蚕豆等粮食生虫时可用此法。选择炎热晴天,将粮食置于易升温的晒场上摊晒。要薄摊勤翻,使粮温上升到48℃左右,并在此温度下持续翻晒3h～4h,然后将粮食趁热聚堆,以保持堆内高温,即可将虫晒死或闷死。待粮温下降到接近大气温度时,再用风车或筛子除去杂质和死虫,然后入仓。
1. Sun exposure Insecticidal exposure is based on solar radiation heat to destroy parasites, so that pests lethal, but also has moisture, mildew effect. Wheat, corn, peas, beans and other food insects available when this method. Select hot and sunny, the food is easy to heat the sun on the market stall. To pave the ground floor turn over, so that grain temperature rose to about 48 ℃, and at this temperature continued sunning 3h ~ 4h, then the grain while hot accumulation, in order to maintain high temperature within the pile, you can sunburn or suffocation. When food temperature drops to near atmospheric temperature, remove the impurities and dead worms from the windmill or sieve, and then put into storage.
