20世纪的化学农业极大地提高了农作物的产量,但随着化肥和农药的过量使用,造成地力衰退、农作物品质下降、环境污染等后果,严重影响到农业的可持续发展。当前,农业正处于由化学农业向生态农业过渡时期,物理农业是实现生态农业的主要途径之一。物理农业就是将电、磁、声、光、热、核等基本物理学科的知识和相关领域的高新技术作为有效的物理肥源应用于农业中,在无污染的条件下达到增产、优质、抗
In the 20th century, chemical agriculture greatly increased the yield of crops. However, with the excessive use of chemical fertilizers and pesticides, the decline of soil fertility and the decline of crop quality and environmental pollution seriously affected the sustainable development of agriculture. At present, agriculture is in the transition from chemical agriculture to ecological agriculture. Physical agriculture is one of the main ways to realize ecological agriculture. Physical agriculture refers to the application of high-tech knowledge of basic physics such as electricity, magnetism, sound, light, heat and nuclear and related fields to agriculture as an effective physical fertilizer source, achieving yield increase, high quality and resistance under non-polluting conditions
