| Abstract |
Dosage rate reduction of plant protection products, mixed with water (spray mixture) in a prescribed concentration in vineyards will be possible in the future, only by taking into account the natural properties of vine canopies (green leaf wall area). In a practical experiment in a vineyard, we evaluated the green leaf wall area grape variety ("Yellow Muscat") on different segments on the left and right row of the vine canopy. We compared the results of manual measurements and laser measuring technology (LIDAR) with the corresponding algorithm, with which we enabled the digital reconstruction of the green leaf wall area of the vine. Using the regression method, we estimated the relationship between the dependent variable (digital number of points in the cloud) and an independent variable (green leaf wall area, manually measured). An analysis of four randomly selected vines in the vineyard showed that the maximum value of the correlation coefficient is r = 0.78 for the left row and r = 0.79 for the right row of the green leafwall area of the vine. |
