摘要
简便、快速、准确的根长测量和根系分级方法,在不同灌溉方式对作物生长影响的对比研究等方面具有重要意义。该文提出了一种利用地理信息系统技术,测量根长并对根系进行分级的方法。通过与目前常用的直接测量法、网格交叉法进行比较,发现该方法测量精度高、速度快,而且简单易用。
It is a very hard work to measure the length and diameter of roots in studies of physiology, genetic breeding, crop cultivation and so on. On the basis of analyzing the characteristics of roots, a method was developed for measurement of root length and diameter by applying geographic information techniques using personal computer and scanner. The result measured using this method was compared with that obtained using grid-counting method and direct-measuring method. It was found that there were close relationships between GIS-measuring method and the other traditional methods, and measurement precision was enough. The procedure is simple with quick measurement speed.
