摘要: 通过调查有螺滩地林下植被的演变和乌柏(Sapium sebiperum)、枫杨(Pterocarya stenoptera)等滩地造林树种的灭螺效果发现,鸡矢藤(Paederia scandens)、水芹(Oenanthe javanica)的个体数量与钉螺的数量呈正相关关系,X2分别为12.8和11.2(a<0.02),而益母草(Leonurus artemisia)、问荆(Equisetum arvense)、酸模叶蓼(Rumex acetosa)、打碗花(Calystegia hederacea)、紫云英(Astragalus sinicus)等与钉螺的数量呈负相关关系(a<0.02)经过一个汛期,枫杨、乌柏叶片使钉螺死亡率从草滩对照的2%升至43.3%和44.1%.

Abstract: The dynamics of grasses in herb layer on beaches with snails and inhibition effects of Sapium sebiferum and Pterocarya stenoptera on snails were studied. Individual quantity of Paederia scandens(X2 = 12.8 ) and Oenanthe javanica (X2 = 11.2) are positively, and that of Leonurus artemisia, Equisetum arvense, Rumex acetosa, Calystegia hederacea and Astragalus sinicus are negatively correlated with the density of snails(a<0.02 ). After the flooding period,the mortality of snails on beaches treated with leaves of Pterocarya stenoptera and Sapium sebiferum is increased by 43.3% and 44.1%, respectively.
