Implementation of Phytotechnology for Sustainable Bioproduction Systems on Ecosystem and Environment Conservation

该项目的目标是在生物建模、生物tron和机器人技术研究的基础上，制定环境/生态系统共生生物生产系统的计划。第二年，将生物建模和生物tron研究部门统一为“生物建模与控制”，并建立了“野外生态系统动力学”作为另一个研究部门。结果表明：建立了根系分枝生长分形模型、植物生长阶段自我发展模型、卡尔曼滤波、神经网络和遗传算法相结合的非线性植物生长模型以及农产品质量判断算法。分析了植物对脉冲磁刺激的反应，估计了植物生长的潜在活性。从植物栽培到收获后的整个生物生产过程中积累了生物建模和控制的数据和技术。提出了农业机器人培育新方法、生物技术微操纵机构、4WD-4WS车辆系统动力学新研究方向和应用现代控制理论的铰接式车辆控制方法。利用“会说话的植物方法”的机器人研究，推动了机械化系统从运行装置到栽培方法的发展。提出了种子种群动态的杂草生活史模型和非化学杂草控制系统。模型中也发现了混沌现象。这些都是田间作物-杂草生态系统动态的重要方面。随着植物技术概念的扩展，结合技术转让分析和作物管理系统，提出了“基于生态系统和环境保护的可持续生物生产系统”的新方案。这些结果被JSAM作为教科书“植物技术（第三部分）”出版。

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)".
