当务之急,农业生产需要可行的技术方案来降低农业生产中对化肥、农药的依赖,构建可持续发展的农业生态与环境。过去的30年,中国利用占世界9%的耕地,解决了占世界总人口20%的13亿国人的吃饭问题,而且到2012年已经保持了粮食连续9年增产,为中国经济增长和社会稳定提供了保障。但这30年间,化肥、农药的使用量不断提升,牲畜粪尿、秸秆等废弃物也大量增加,已造成农村和农田的广泛面源污染和土壤肥力下降等严重问题,恶化了生态和城乡人民的生活环境。根
At the top of the agenda, agricultural production requires viable technical solutions to reduce the dependence on fertilizers and pesticides in agricultural production and to build a sustainable agricultural ecology and environment. Over the past 30 years, China has used 9% of the world’s cultivated land to solve the problem of eating 1.3 billion Chinese people, which accounts for 20% of the world’s total population. By 2012, China has maintained grain production for 9 consecutive years and provided economic growth and social stability in China Provided a guarantee. However, over the past 30 years, the use of chemical fertilizers and pesticides has been on the rise. The excrement of livestock excrement, straw and other wastes have also increased substantially. These have caused serious problems of widespread non-point source pollution and soil fertility decline in rural areas and farmland, deteriorating ecological and urban and rural people Living environment. root
