农业部环境监测总站和中国环境科学院的一项研究表明,包括农药、化肥、地膜的不合理使用造成的农业自身污染在我国农业环境总体影响中已占相当比例,至2020年的发展趋势也不容乐观。有关专家呼吁,应加强农业自身污染防治研究和对策实施工作。 由于我国播种面积广,病虫草害的发生面积也很大,近10年来,我国每年使用农药防治面积23亿亩次,每年平均挽回粮食损失占总产的6％,棉花占总产的10％,蔬菜和果品各占20％,成效较为显著。但是,施于田间的农药准确击中防治对象的仅占极少部分,其余扩散到农业环境,造成了污染。1990年农业
A study conducted by the Ministry of Agriculture Environmental Monitoring Station and the Chinese Academy of Environmental Sciences shows that the agricultural pollution caused by irrational use of pesticides, chemical fertilizers and plastic films has accounted for a considerable proportion of the overall impact on the agricultural environment in our country and the trend of development up to 2020 can not be tolerated optimism. Relevant experts called for the prevention and control of agriculture should strengthen its own research and implementation measures. Due to the wide planting area in our country, the occurrence area of pests and weeds is also very large. Over the past 10 years, China has used 2.3 billion mu of pesticide-control areas each year, with an average of 6% of the total grain loss every year. Cotton accounts for 10% , Vegetables and fruits each account for 20%, the effect is more obvious. However, only a very small part of the pesticides applied to the field hit the target of control and the rest spread to the agricultural environment, causing pollution. 1990 agriculture
