【摘要】：随着科学技术的发展,数字农业和虚拟现实技术的交叉学科-虚拟农业研究,已成为当前现代农业领域的研究热点。我国对于虚拟作物研究的起步较晚,主要针对小麦、玉米、棉花、大麦等常见单茎农作物,作为世界性高产水果的葡萄,其虚拟可视化研究还比较少。。本研究以甘肃地区红地球品种葡萄作为研究对象,在标准栽培技术下,连续两年对该品种葡萄的主干、主蔓、侧蔓、结果母枝等形状参数进行测量,并着重定时测量了结果母枝上新生枝条的节间、叶柄、叶片、花序等的几何参数,以及实验葡萄园的温度和风速等气象数据,拟合了葡萄新生枝条的生长模型。本文完成了以下研究工作:(1)通过田间实验观测,分析研究葡萄各个器官的形态结构特征和生理发育特性。(2)通过田间实验数据的采集、整理和分析,研究了葡萄枝条与器官的“S”型生长规律。通过对几种“S”型曲线方程的实际对比,选定Richards方程作为葡萄主要器官描述模型,结合实际测量数据,确定了葡萄各个器官的生长发育模型以及生长模型参数。(3)生长发育模型检验。实验结果表明本研究对红地球葡萄新生枝条的的节间、叶片、叶柄、花序等器官的生长发育有很好的预测性,能够比较准确的拟合葡萄新生枝条的生长动态,符合植物枝条的生物学规律。实验研究对进一步构建葡萄生长发育模型奠定了技术基础,并为最终实现葡萄生长发育的可视化表达提供了理论依据。
[Abstract]:With the development of science and technology, the research of virtual agriculture, which is an interdisciplinary subject of digital agriculture and virtual reality technology, has become a hotspot in the field of modern agriculture. The research on virtual crops in China started late, mainly aimed at wheat, corn, cotton, barley and other common single stem crops. In this study, the red earth grape in Gansu area was used as the research object. Under the standard cultivation technique, the shape parameters of the main vine, lateral vine and fruiting mother branch were measured for two years in a row. The geometric parameters of the nodes, petioles, leaves, inflorescences, and the temperature and wind speed of the experimental vineyard were measured at regular intervals to fit the growth model of the new branches of grape. In this paper, the following research works have been completed: (1) through the field experiment observation, to analyze and study the morphological structure and physiological development characteristics of each organ of grape; (2) to collect, organize and analyze the data of the field experiment. The "S" growth pattern of grape branches and organs was studied. Based on the comparison of several "S" curve equations, Richards equation was selected as the description model of main organs of grape, and the actual measured data were combined. The growth model and growth model parameters of each organ of grape were determined. (3) growth and development model test. The results showed that this study could predict the growth and development of new branches of red earth grape, such as internodes, leaves, petioles, inflorescences and so on. It accords with the biological law of plant branches. The experimental study laid a technical foundation for the further construction of grape growth and development model and provided a theoretical basis for the visualization of grape growth and development.
