水稻群体动态预测与栽培决策

POPULATION DYNAMICS PREDICTION AND CULTIVATIONAL DECISION MAKING OF RICE CROP

本文以作物计算机模拟技术为基础，根据天气、土壤、苗情，模拟预测水稻群体的发育群、茎蘖消长、叶面积动态、光合生产与产量形成。并运用系统控制论方法，根据预测结果与最佳群体指标的比较以及有关决策调控模型，提出使未来群体向着最适群体发展的栽培决策。

Using the data of weather, soil and rice crop, the authors at first simulated and predicted the phenophase, the tiller formation and death, the leaf area dynamics, the dry matter accumulation, and the grain formation of rice by means of a number of simulation models. According to the results of a comparison between the values of predicted and the optimum based on a high yield cultivation theory and some decision-making models, a series of cultivational decisions to lead the rice population dynamics towards the optimum were then made by using the system cybernetics theory.
