At nutrition and moisture comparativelyUnder sufficient condition, the size of crop photosynthesis depends on the photosynthetically active radiation that arrives blade(PhotosyntheticallyActiveRadiation is called for short PAR). But, in production practices, cropThe blade of canopy differing heights can not obtain sufficient luminous energy, thereby makes blade in fact in light hungerState, and cause crop failure. Therefore, the regularity of distribution of photosynthetically active radiation is agriculture, ecological etc. in canopyThe important content in field, especially agriculture soil and water management important technology index.
At present, the effective radiation detection of canopy photosynthesis adopts hand-held PAR analyzer mostly, or adopts multipleThe photosynthetically active radiation of fixed and arranged in canopy carries out detection of fixed place and time. The number of manual measurement in said methodAccording to discontinuous and have a subjective error, the method for manual measurement measures that cost is high, measurement data amount is little, and needsArtificial authentication data quality of later stage, this data measuring method is made troubles to scientific research and production application. FixedThe online real-time measurement apparatus of point has solved a difficult problem for data Continuous Observation, but due to sun altitude and azimuthalReal-time change, easily measures numerical value to PAR and causes larger difference.
