摘　　要：利用扫描电子显微镜观察 ,对花卉盆钵气孔进行分析 ,量化 ,并提出气孔度的新概念 ,按花卉盆钵气孔度大小聚类分类 .花盆内壁、横断面、外壁气孔对透气性、吸水性 ,具有共同作用功能 .它们作用过程是双向的 ,从外壁气孔→横断面气孔→内壁气孔方向的作用是主要的 .而外壁气孔是作用的主要因子 .本研究表明 ,8种花盆对石竹生长的影响是佛山瓦花盆最好 .在塑料类中 ,日本塑料花盆最好 ,其次是台湾塑料花盆 ,再次是顺德塑料花盆 .Using scanning electronic microscope, gas hole of flowerpots were studied and analyzed quantitatively and a technical terms, gas hole degree was put forword, on which clustering analysis was based. The gas hole of inner, outer and cross sections of flowerpots had similar two way effects on ventilation and absorption. But the direction from outer section to cross section to inner section was the main trend and the gas hole on the outer section was the main factor. According the effects of 8 types of flowerpot on the growth of chinese pink, the results indicated that Foshan earthen flowerpots were the best. As for plastic pots, the pots made in Japan were the best; Taiwan's pots ranked second; and the last one is Shunde's pots. The study also suggested that modeling through experimentation and optimal subset regression should be a good way for the development of flowerpot products.
