地下热水,是大气降水或地表水,沿着岩石裂隙渗入到深部含水层或含水构造中,被岩浆热或者覆盖在岩浆上的热岩体加热而形成的.如我们日常所见的温泉便是.地下热水,按其温度分为低温热水(20—40℃),中温热水(40—60℃)和高温热水(60—100℃)三种.地下热水,在农业上的应用比较广泛.早在东周时代,我们的祖先就已经利用地下热水灌溉、到了近代,地下热水在农业上的应用又有了进一步发展.目前有地下热水
Underground hot water, either atmospheric precipitation or surface water, penetrates into deep aquifers or aquifers along rock fractures and is heated by magmatic heat or hot rock masses that cover the magma, as we have seen in our daily life Underground hot water, according to its temperature is divided into low-temperature hot water (20-40 ℃), the hot water (40-60 ℃) and hot water (60-100 ℃) three underground hot water in agriculture As early as in the Eastern Zhou Dynasty, our ancestors have been using underground hot water irrigation, in modern times, the underground hot water in agricultural applications has been further developed.At present, underground water
