粮食贮藏有四大害,即虫、霉、鼠、雀。经过多年努力,国家粮库的贮粮损耗控制在0.2%。比之热带一些国家损耗率在5～15%之间,实为一大成绩。但相比之下,农村种子粮的贮藏损耗仍属惊人。据调查,浙江的稻、麦种子在贮藏中由于害虫侵蚀,有25%的种子失去发芽力,重量损耗在5%。云南边疆一些县份中,贮满一年的稻谷损耗率达15%。如以全国统计,则每年种子损失十分严重。因此,应当特别重视害虫的防治工作。 Food storage has four major hazards, namely insects, mold, rats, birds. After years of hard work, the grain storage loss of the state grain storage is controlled at 0.2%. Some countries than the tropical rate of loss of 5 to 15%, in fact, a major achievement. However, in contrast, the storage loss of rural seed grain is still staggering. According to the survey, Zhejiang rice, wheat seeds in the storage due to pest erosion, 25% of the seeds lose germination power, weight loss at 5%. Some counties in the border area of ​​Yunnan Province have a year-long rice loss rate of 15%. As with national statistics, the annual loss of seeds is very serious. Therefore, special attention should be paid to pest control.
