每到夏季，家庭贮存的大米往往会生虫子，如不进行防治，就会越生越多，甚至不能食用。如果采用杀虫剂防治，不仅费事，而且会污染大米和环境，非常不安全，实在是让人束手无策。经我们多次试验，采用速冻法防治，不但能将虫子全部灭掉，而且不污染大米和环境，方法简便易行。 Every summer, rice stored in families tends to be insects, and if they are not controlled, they will grow more and more, or even be inedible. Insecticide control is not only wasteful but also pollutes the rice and the environment. It is very unsafe to do so. After our many tests, the use of quick-freezing method of prevention and control, not only can exterminate the insects, but also does not pollute the rice and the environment, the method is simple and easy.
