Abstract

The invention discloses a method for calculating canopy photosynthetic rate and is applied to plant canopy basic researches and agricultural plant seedling nursing field and measuring effects of cultivation measures to the plant canopy photosynthetic rate. The technical scheme is that for plant type parameters and cultivation parameters, a canopy reconstruction method is utilized to build a canopy three-dimension structure; by the use of ray tracing algorithm and based on the built canopy three-dimension structure, light distribution of each leave in the canopy can be acquired; leave metabolic characteristics can be achieved and a plant leave metabolic model is parameterized; and the built canopy three-dimension structure, the light distribution of each leave and the parameterized plant leave metabolic model are integrated, so the whole canopy photosynthetic rate can be calculated.

Description

technical field [0001] The invention relates to a method for calculating the photosynthetic rate of plants, in particular to a method for calculating the photosynthetic rate of plant canopies. Background technique [0002] It has been proved by many experiments that improving photosynthetic efficiency can further increase crop yield. However, in breeding and production practice, people still can only screen photosynthetic efficiency per unit leaf area, and there is no means to measure canopy photosynthetic efficiency directly related to crop yield. Canopy photosynthesis refers to the sum of photosynthesis of all leaves in the whole above-ground part. In the canopy, each leaf has a different microenvironment, such as light intensity, temperature, humidity, etc., and there are differences in photosynthetic physiological parameters among different leaves. The light of each leaf in the canopy is different, and the enzyme activity related to photosynthesis of each leaf is also ...
