作物生长与土壤水分条件关系的可视化研究

To quantify the water movement and transportation of soil-crop system, it is necessary to study the structure characteristics of crop aerial part and root system. New 3D digitizer was used to study the 3D architecture characteristics of maize and cotton canopy, and visualization of plant architecture was realized. Spatial light distribution of maize canopy was measured in field and light transmittance model of crop canopy was developed by using radiosity method. A architecture model which based on the interaction of plant function and structure was developed, environment function(soil water condition) on crop growth was studied also.

对土壤－作物系统水分运动与转化的精确定量化研究，是确定农业节水措施的基础．本项目拟在已有的研究基础上，采用高效的数据采集技术，提取作物生长规则，研究土壤水分条件对作物生长的定量化作用：应用可视化技术建立可精确反映水分条件对作物生长作用关系的可视化系统．应用该系统进行计数机虚拟实验，研究土壤－作物系统水分运动的时空规律．
