二氧化碳是植物进行光合作用的一种重要原料,因此,测定大气中二氧化碳浓度的减少就可以知道光合作用的强弱。下面谈谈用QGD-07型手提式红外线二氧化碳分析器(北京分析仪器厂出品),测定一些作物田间光合作用的方法和体会。仪器的工作原理和测定方法红外线二氧化碳分析器的工作原理,是基于二氧化碳对波长为4.26微米(μ)的红外线有较强的吸收能力,其吸收程度由二氧化碳浓度来决定。QGD-07型红外线二氧化碳分析器以4.26微米红外线为测量光,以3.9微米的红外线
Carbon dioxide is an important raw material for photosynthesis in plants. Therefore, the determination of the reduction of atmospheric carbon dioxide concentration can know the strength of photosynthesis. Here to talk about using QGD-07 type portable infrared carbon dioxide analyzer (Beijing Analytical Instrument Factory produced), determination of some crop field photosynthesis method and experience. How it works and how it works The infrared CO2 analyzer works based on the fact that CO2 absorbs infrared light with a wavelength of 4.26 microns (μ) and its absorption is determined by the concentration of carbon dioxide. QGD-07 infrared carbon dioxide analyzer to 4.26 micron infrared light measurement, 3.9 micron infrared
