Grassland biomass measuring method and device

The invention relates to the technical field of grassland biomass measurement, and provides a grassland biomass measurement method and device.The grassland biomass measurement device comprises a frame body and further comprises a moving mechanism, a sampling mechanism, a photographing mechanism, a soil returning mechanism, a sample weighing mechanism and a soil sample collecting component; the sampling mechanism is used for sampling grassland organisms and soil in the quadrat, the photographing mechanism is used for photographing grassland organism stems and leaves on the ground and grassland organism roots under the ground, and the soil returning mechanism is used for returning redundant soil to the ground. The sample weighing mechanism is used for collecting grassland organisms in the sampling frame and weighing fresh weight and dry weight of the grassland organisms, and the soil sample collecting part is used for collecting soil samples in the soil sampling barrel. By means of the technical scheme, the pro
