Abstract

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. The combined analysis method was constructed to obtain the respiration characteristics of alfalfa artificial grassland through multiple validations, so as to achieve the degree of impact on the respiration characteristics of the grassland analysis. The experimental results show that the proposed verification methods can explain the existence of growth redundancy and propose a method to reduce redundancy. Moreover, the proposed analysis method has more complete respiratory characteristics and the analysis results of photosynthesis and total vegetation yield are more consistent with the reality.
