| Research Abstract |
The objective of this project was the development of a plan for environment/ecosystem-symbiotic bioproduction systems based on the studies on biomodeling, biotron, and robotics. In the second year, the biomodeling and biotron reseatch divisions were unified to "biomodeling and control", and "ecosystem dynamics in the field" was built up as an another study division. Results were as follows :
A model for branching growth fractal patterns of root system, a model of self-development of growth stage of plant, a non-linear plant growth model associated with Kalman-filtering, neural network and genetic algorithms, and a quality judgment algorithm for agricultural products, were established. Plant responses to impulsive magnetic stimuli were analyzed and potential activities of plant growth were estimated. The data and techniques on biomodeling and control were accumulated over the bioproduction system from plant cultivation to post harvest processes.
A new cultivation method for agricultural robots, micro-manipulation mechanisms for biotechnology, new aspects on 4WD-4WS vehicle system dynamics and an articulated vehicle control method with the modern control theory, were developed. Robotics researches using "Speaking Plant Approach" were promoted over the mechanization system from running devices to cultivation methods.
A model of weed life history for seed population bynamics and a non-chemical weed control system were proposed.Chaos in the model was also found. These were important aspects on crop-weed ecosystem dynamics in the field.
With expanding the concept of phytotechnology, a new plan "Sustainable Bioproduction Systems based on ecosystem and environment conservation" was proposed in linkage with technology transfer analysis and crop management system. These results are published by JSAM as a textbook "Phytotechnology (Part3)".
