摘要
为了应对中国农业生产中大量使用化肥带来的土壤污染等一系列环境及食品安全问题,采用考察文献资料的方法,梳理中国古代有机肥制作和使用的经验,总结出中国古代长期使用有机肥具有可循环、无害环境的优点,但相对化肥,其提高产量的作用有限。因此,在农业用地质与量均有下降的情况下,要保证农业产量及农业的可持续发展,必须统筹使用有机肥与无机肥。
In order to deal with a series of environmental problems and food safety issues caused by overuse of chemical fertilizers in China, a method based on collating historical documents was proposed. The organic fer- tilizer used in ancient China for a long term had two traits, which are the organic fertilizers that can be recy- cled and do no harm to the environment. While, compared with chemical fertilizers, they are limited in in- creasing the yields. In order to ensure the yields and sustainable development of agriculture, organic fertilizer and chemical fertilizer must be made overall arrangements under circumstance that both quality and quantities of the land deteriorated.
