In the constructed wetland system, wetland plants are very important components that have the effect of degrading and removing pollutants, and play a very important role in maintaining a good ecosystem of constructed wetlands. The transpiration of plants is the main driving force of water uptake in plant roots. The plants with strong transpiration have high growth vigor and the ability to absorb nutrients is often strong. Therefore, the plant transpiration rate analyzer can be used to pay close attention to the plant transpiration rate of the constructed wetland system. What are the factors that affect the transpiration rate of plants, and take reasonable measures to improve, in order to improve the growth of wetland plants to ensure its healthy growth.
In general, plant transpiration is the result of many aspects of ecological factors, so it is actually very complex. Their influence on the transpiration intensity of wetland plants does not exist independently, but mutual constraints and mutual influence, so to analyze For factors affecting the transpiration rate of wetland plants, the transpiration rate of cannabis plants such as canna and reed must be measured using the plant transpiration rate analyzer in all weather conditions, combined with meteorological factors, and finally determine which factors affect the transpiration rate of wetland plants. most influential.
In the course of the research, the plant transpiration rate meter mainly measured the two common wetland plants, Canna and Reed. Through the measurement and analysis, it was found that the meteorological factors' impact on the canopy transpiration rate was from the largest to the smallest. : leaf hole conductance, light intensity, relative humidity, and temperature; the effect of meteorological factors on the transpiration rate of reeds from big to small is: light intensity, leaf hole conductance, relative humidity, air temperature, relative humidity and canna and The transpiration rate of reeds is negatively correlated. Although the meteorological factors have different effects on the transpiration rate of wetland plants, comprehensive comparison will reveal that leaf hole conductance and light intensity are important influencing factors, and the impact of temperature is relatively small.
