生物农药选择性高,对生态系统影响小,有些生物农药还有一定的肥效,因此许多方面都比化学农药有明显的优势。但是从中国市场上看,农民购买使用生物农药的热情并不高,产品积压严重。据统计,中国生物农药施用面积不到总面积的0.5%。生物农药为何“叫好不叫座”?有关专家认为,造成此种现象的原因可从企业和消费者这两方面获得。
Bio-pesticides have high selectivity and have little impact on ecosystems. Some bio-pesticides have a certain degree of fertilizer efficiency. Therefore, many aspects have obvious advantages over chemical pesticides. However, from the perspective of the Chinese market, farmers’ enthusiasm for buying and using bio-pesticides is not high and the product backlog is serious. According to statistics, China’s biological pesticide application area is less than 0.5% of the total area. Why do the biopesticides make you feel good? Experts believe that the reasons for this phenomenon can be obtained from both the enterprise and the consumer.
