The degree of dense planting affects the respiration characteristics of alfalfa artificial grassland. In the process of alfalfa seed production, high plant and multibranch forage can be obtained by reasonable close planting. Therefore, an analysis method of the effect of reasonable close planting on respiration characteristics of garden alfalfa artificial grassland is put forward. In this method, the density characteristics of alfalfa planting were determined from three aspects of plant horizontal density, vertical density and three-dimensional density. The infrared carbon dioxide gas analyser was used to measure the carbon dioxide flux of the garden. |
