Botany Model role 2011-08-02

For the quantitative study of the growth pattern of plants, from the mid-1960s, researchers began the study of plant growth simulation. That the model through the simulation of plant physiological and ecological processes, under different environmental conditions to predict the growth of plants, some integrated indicators, such as crops, pasture biomass, leaf area index dynamics, organ biomass, quantity, etc. , and in plant morphology and spatial and temporal variation of environmental factors on plant growth and other aspects of simplification. Combination of these models and expert systems, and other areas of agricultural production has an important significance, but for some new application areas, has been difficult to meet the requirements.
The farm system, for example, small-scale farmland within the scope of environmental conditions, crop growth will have a clear temporal and spatial variability, developed rapidly in recent years of precision agriculture is based on the difference of the birth. On the water, since soil conditions, crop canopy and root morphology in a small scale will have a great range of temporal and spatial variation, the variation of root water uptake, soil evaporation, crop transpiration have a great impact, but eco-physiological model in dealing with the temporal and spatial variability of plant and soil were larger in terms of simplification, it is difficult for water movement and transformation of farmland to achieve precision to determine the quantitative research.
In recent years, the botany, agronomy, ecology, mathematics, computer graphics and many other interdisciplinary and rapidly developed Botany Model, with the potential to meet these needs. In general, the physiological parameters of ecological models with easy access, less demanding on computer performance, etc., suitable for production forecasting, land productivity evaluation of the application; and the virtual plant model parameters is more complex, higher performance requirements on the computer, in requires high spatial resolution, and the field of plant morphology related applications has more advantages in precision agriculture, ecosystems, energy flow object space law studies, remote sensing of plant growth conditions, landscape design, virtual teaching and other fields have broad application prospects .
Model Botany Model for the study of plants and protection of human plants played a very important role.
