6种灌木耐水淹能力分析

Analysis of Water Logging Tolerance of 6 Frutexes

以小叶蚊母、滨柃、水杨梅、龟甲冬青、罗城石楠、花叶杞柳6种灌木为研究对象,在人工控制的水淹条件下,观察其叶片水淹胁迫后的症状,分析其耐水淹能力,结果表明:水淹30 d后,小叶蚊母、水杨梅和花叶杞柳植株少量叶片出现水渍斑,排除多余水分并经过常规养护30 d后,植物生长恢复正常;而滨柃、龟甲冬青和罗城石楠水淹30 d后全部死亡。

Under the condition of manually-controlled water logging,the symptom of leaves was observed and water logging tolerance was analyzed on the following 6 frutexes： Distylium buxifolium,Eurya emarginata,Adina rubella,Ilex crenata Convera Makino,Photinia lochengensis and Salix integra Hakuro Nishiki.The results showed that Eurya emarginata,Ilex crenata Convera Makino and Photinia lochengensis all died after being waterlogged for 30 days;after 30 days＇ water logging,only few water-soaked spots appeared on Distylium buxifolium,Adina rubella and Salix integra Hakuro Nishiki,and then they became normal after removing the excess water.
