气肥来源于空气中的二氧化碳,这是一种取之不尽,用之不竭的自然资源。据科学家推算,约在40亿年前,地球上还没有生物的时候,自然界就已经有二氧化碳存在了。后来,经过若干亿年演进变化,植物出现了,于是植物通过本身的叶子,吸收大自然中的二氧化碳和水,借助于日光,进行了一种很复杂的光合作用,使植物繁茂生长,种粒相传,衍续至今。绿色植物所进行的这种光合作用,大约每年要吸收近8000亿吨的二氧化碳,相应地放出5000亿吨的氧,于是又为地球上的生态平衡提供了所必需的物质基础。综观一百多年来的实验结果,人们清楚地看到了植物的受益:叶子面积增加了,叶面单位面积的干燥重量
Gas from the carbon dioxide in the air, which is an inexhaustible natural resources. According to scientists projections, about 4 billion years ago, there is no creature on Earth when there is already carbon dioxide in nature. Later, after several hundred million years of evolution, plants emerged, and plants absorbed carbon dioxide and water from nature through their own leaves. With the help of sunlight, they carried out a very complex photosynthesis that led to the flourishing growth of plants. According to legend, so far. This photosynthesis by green plants absorbs nearly 800 billion tons of carbon dioxide a year, correspondingly emits 500 billion tons of oxygen, thus providing the necessary material basis for the ecological balance on Earth. Looking at the results of more than 100 years of experiments, people have clearly seen the benefits of plants: leaf area increased, leaf dry weight per unit area
