人造土壤技术的合理性
The rationality of AST

    人造土壤的基本原理与自然界土壤形成的机理基本相同,差异之处在于人造土壤形成的时间与过程大大的缩短了。在自然界,任何类型的土壤都是由坚硬的岩石变成的,但这是个漫长而复杂的过程,要经历数十万年,数百万年甚至上千万年才能完成。从这个意义上讲,土地资源确实是有限的。可是人造土壤也是应用这些基本原料(岩石),却在极短的时间内变成具有水、肥、气、热四大功能,基本具备植物生长条件的人造土壤,其时间之短,我甚至可以这样承诺:你从山上或者煤矿巷道里挖来一块大石头(如安山岩、玄武岩、煤矸石、黑色泥岩),我在1小时内粉磨成无机原料粉(即造土母质),在半小时内将无机原料粉与事先准备好的造土堆肥按一定比例混合配制成人造土壤,然后在半小时内播下小麦种子,全部过程用不了2个小时就把大石头变成了人造土壤。并且我还保证,3天后小麦种子会破土出芽,2个月零10天之后能结出麦穗。从时间上看,把自然界数十万年、数百万年的过程缩短到2小时之内。从这个意义上讲,土地资源确实不是有限的。我们再从矿物成分和化学元素分析的角度来看,天然土壤与人造土壤没有什么差别,这就是人造土壤技术的合理性之所在。
 

人造土壤技术的合理性
The rationality of AST

The basic principle of artificial soil is more or less the same as the mechanism of forming natural soil. The difference lies in that the time needed for artificial soil to form and the process is greatly shortened. In nature, any kind of soil comes from hard rocks, and it is a lengthy and complex process, which takes hundreds of thousands of years, millions of years or even millions upon millions of years. In this sense, land resources are limited. However artificial soil which is made of these basic materials (rocks) can have the four functions of water, fertility, air and heat and the basic conditions for plants to grow in a extremely short time. The time duration is so short that I can even make such a promise. You dig a stone from a hill or coal mine tunnel (eg. andesite, basalt, gangue, black mudstone). I make the stone into inorganic powder (i.e. parent material manufacturing soil) within one hour and mix it with prepared compost manufacturing soil in certain proportion to make artificial soil within half an hour. Then wheat seeds can be sowed within another half an hour, so it takes less than 2 hours to change the big stone into artificial soil. I can make another promise. The wheat seeds will sprout in three days and ear of wheat will be seen in 70 days. In terms of time, the natural process taking hundreds of thousands of years or millions of years has been shortened to less than 2 hours. In this sense, land resources are not really limited. In terms of the analysis of mineral components and chemical elements, natural soil has no difference from artificial soil, which states the rationality of artificial soil technology.
