Abstract

The invention relates to a biological detection method based on gas isotope detection. The method comprises the following steps: selecting a sample plant; cultivating the sample plant to a detection platform; introducing a mixed gas of carbon dioxide with carbon isotopes, oxygen and nitrogen into the detection platform; waiting for photosynthesis of the sample plant; recording detection time; extracting part of residual air in the detection platform as sample air; compressing the sample air; detecting the content of carbon dioxide in the sample air; measuring the content of carbon dioxide withcarbon isotopes; adjusting the environment condition; waiting for photosynthesis of the sample plant; extracting part of residual air in the detection platform as sample air; compressing the sample air; detecting the content of carbon dioxide in the sample air; measuring the content of carbon dioxide with carbon isotopes on the basis of carbon dioxide; and comparing the content of the carbon dioxide with the carbon isotope and recording the environment corresponding to the measurement result with less content.

Description

technical field [0001] The invention relates to the field of biological detection, in particular to a biological detection method based on gas isotope detection. Background technique [0002] For crops, light is an external condition necessary for growth and an energy source for plants to photosynthesize and synthesize sugars. The influence of light on crop growth is manifested in three aspects: light intensity, photoperiod and light quality. Nowadays, for the crops in the greenhouse, agricultural technology often provides a certain amount of artificial synthetic light instead of natural sunlight, which will cause a waste of sunlight and energy, instead of using artificial synthetic light and only using sunlight , can not meet the requirements of scientific and technological agriculture. [0003] It is an urgent problem to be solved to detect plants according to different lighting conditions, thereby adjusting the air conditions in the process of plant growth, and then pro...
