“水利是农业的命脉”,近代对土壤水分的研究,逐渐进入到以“能量概念”为基础的领域中,不仅着眼于土壤的本身,而且考虑到植物体内甚至大气中水分能量转化的状况,也就是把水从土壤经过植物体到大气的流动过程,作为一个物理的统一的动态连续系统进行研究。在这个动态连续系统中水分循环的过程和途径,就象运动着的链条里各个环节一样,互相连接,互相依赖,形成了一个统一的土壤—植物—大气连续系统(Spac)。这是当今国际国内大力倡导“生态平衡”中关键性的一环,也正是党的十二大号召开创社会主义现代化建设新局面中,农业上改善和保持、恢复生态平衡中的主
“Water conservancy is the lifeblood of agriculture.” In modern times, research on soil moisture has gradually entered into the field based on the concept of “energy,” not only focusing on the soil itself, but also taking into account the state of moisture energy transformation in plants and even in the atmosphere. That is, the flow of water from the soil through the plant body to the atmosphere, as a physical unified dynamic continuous system. The process and route of water circulation in this dynamic continuous system, like all links in a moving chain, are interconnected and interdependent, forming a unified system of soil-plant-atmosphere continuity. This is a key link in vigorously advocating “ecological balance” both at home and abroad today. It is also the moment when the 12th CPC National Congress called for a new situation in the socialist modernization drive to improve and maintain agriculture and restore ecological balance
