二次大战以来,以机械化、肥料化、灌溉化、化学化为标志的现代农业,获得了迅猛的发展,现代农业国外又称为石油农业或能源农业。其基本思想,就是最大限度地投入能量,以获取最高的农业产量。高能量的投入,一方面使粮食产量成倍地增长,但另一方面又从根本上造成了农业自给系统的破坏,例如资源的破坏,环境的污染,生态平衡的破坏以及其它政治、经济、社会问题等等。西方不少学者惊呼:石油农业的进一步发展,将导致农业乃至整个国民经济的崩溃!因此人们不得不去寻求新的农业发展道路。 近十多年来,通过对“有机农业”、“生物动力学农业”和“生态农业”进行研
Since the Second World War, modern agriculture marked by mechanization, fertilizer, irrigation and chemical chemistry has witnessed rapid development. Modern foreign agriculture is also called petroleum agriculture or energy agriculture. The basic idea is to maximize the energy input in order to obtain the highest agricultural output. The high energy input, on the one hand, has doubled the grain output but on the other hand, it has fundamentally caused the destruction of the system of agricultural self-sufficiency such as the destruction of resources, the pollution of the environment, the destruction of the ecological balance and other political, economic, Social issues and more.
