夹竹桃等七种植物野外栽培灭螺效果的试验研究

Study on Molluscicidal Effect of Nerium indicum and other 7 kinds of plants in Field Cultivation

对灭螺植物材料夹竹桃、枫杨、乌桕、益母草和对照植物材料杨树、芦苇、杂草开展野外栽培灭螺试验。结果表明:灭螺植物材料的钉螺死亡率高于对照植物材料,并达到显著差异水平,其中夹竹桃灭螺效果最好,乌桕、益母草、枫杨相差不大且均大于杨树小于夹竹桃,对照植物杨树的灭螺效果好于芦苇和杂草。

The tests of killing snails with 7 molluscicidal plants in field cultivation were carried out,including Nerium indicum,Pterocarya stenoptera,Sapium sebiferum,Leonurus heterophyllus,with Populus cathayanna,Phragmites australis and weed as control plants.The results showed that the snail mortality of molluscicide plants was higher than that of control plants and reached significant difference.At the same time,it was found that the molluscicidal effect of Nerium indicum was the best,and that of Pterocarya stenoptera,Sapium sebiferum,Leonurus heterophyllus differed little,but better than that of Populus cathayanna and wors than that of Nerium indicum.Furthermore,the molluscicidal effect of Populus cathayanna was better than that of Phragmites australis and weed.
