Tomato is a common food on the human table. Up to
now, the research on the growth and development model of tomato has been about
50 years. There are many researches on the main nutrients of tomato, such as
carbon and nitrogen, but few on the trace element zinc. In this paper, taking
plant nutrient C, N and Zn as variables, the differential equation model of C, N and Zn in tomato growth
and development was established. According to the research of tomato as a whole
and divided into root and leaf, the one-compartment and two-compartment models of tomato
growth and development were established. The model was analyzed by Matlab
program, and the existing experimental data was used to test the numerical
simulation results, which proves that the model conforms to the facts.
