近些年来,随着人类对生态环境的日趋关注和对无污染食物需求的增加,发展有机农业也受到越来越多国家的重视。所谓“有机农业”,是指不用化肥和化学农药、依靠科学的耕作方法和田间管理、施用有机肥和生物除虫剂而发展起来的农业,同“原始农业”相近似。用这种方法生产出来的粮食、水果和蔬菜被统称为“有机食物”。比起现行农业中施用无机肥、化学农药生产出来的食物,这种“有机食物”显然对人类更有益,因而更受欢迎。在一些发达国家,市场上经常可以看到不同价格的同一种食品,其中价格偏贵的便可能是那种被称为“无污染”的“有机食物”。
In recent years, with the increasing concern for the ecological environment and the increase in the demand for pollution-free food, the development of organic agriculture has also received more and more attention from countries. The so-called “organic agriculture” refers to agriculture that has been developed without chemical fertilizers and chemical pesticides, relying on scientific farming methods and field management, application of organic fertilizers and biological insecticides, and is similar to “primitive agriculture.” The food, fruits and vegetables produced by this method are collectively referred to as “organic foods.” This “organic food” is obviously more beneficial to humans than food currently produced in agriculture using inorganic fertilizers and chemical pesticides, and is therefore more popular. In some developed countries, the market can often see the same kind of food at different prices, of which the price is expensive may be the kind of “organic food” called “no pollution”.
