The parameters found can be used to predict the increment of tree diameter,
predict the growth of plantation volume, an increase in the area of CPE foliation, and,
therefore, predict the CPE condition parameters.
CONCLUSION
Based on the use of input information provided by the YT, an algorithm for
calculating the parameters of photosynthesis has been developed.
Identified are the quantitative relationships between the parameters of
photosynthesis and the diameter increment of a woody plant.
A mathematical model for calculating the diameter increment of a CPE woody
plant was developed and the equation of its diameter increment was obtained,
depending on the parameters of photosynthesis and time.
The results suggest that the equation for changing the diameter and height of a
tree in conditions of competition for light is obtained and the problem of optimizing
the parameters of photosynthesis in it is solved, which allows predicting the CPE
condition index as one of the important parameters of the quality of the functioning of
protective plantations.
