摘要
目的了解广西百色市周边地区土壤中土源性线虫污染情况,为开展土源性线虫防控提供依据。方法按距市中心的远近选取4个乡镇作为调查点,每个乡镇随机选取15户农户的菜园及厕所周边进行采样,各采集1份土壤,共120份。采用改良饱和硝酸钠漂浮法检测土壤中蛔虫卵、鞭虫卵及粪类圆线虫幼虫污染情况。结果 4个乡镇土壤土源性线虫总检出率高低分别为阳圩镇高于永乐镇(χ2=11.171,P=0.001)、阳圩镇高于汪甸乡(χ2=32.116,P<0.001)、汪甸乡高于那毕村(χ2=30.488,P<0.001),永乐镇与汪甸乡差异无统计学意义(χ2=5.952,P=0.015>0.008)。粪类圆线虫检出率高于鞭虫卵检出率(χ2=15.000,P<0.001<0.017),蛔虫卵检出率与鞭虫卵检出率(χ2=5.400,P=0.020>0.017)、蛔虫卵检出率与粪类圆线虫检出率差异均无统计学意义(χ2=2.660,P=0.103)。厕所周边蛔虫卵/鞭虫卵检出率高于菜园(χ2=4.728,P<0.05)。结论百色市周边地区土壤存在土源性线虫污染,应继续加强粪便无害化处理,以降低土壤土源性线虫的污染。
Objective soils in Guangxi Baise city To understand the pollution status of soilborne nematode in the peripheral locality , in Order to provide references for developing soilborne nematode prevention and control. Methods The sanitation of soil was monitored in 4 towns, according to the distance to the urban district centre. One soil was sampled randomly in the vegetable garden and around the lavatory from 15 farmers in each town,with a total of 120 soil samples. A modified saturated sodium nitrate floating method was used to detect the pollution status of Ascarid eggs, whipworm eggs Strongyloides stercoralis larva in soil samples. Results The detection rates of soil--borne nematod ranked in the four towns were ranked that Yangxu town was higher Yongle town （x^2 =11. 171, P =0. 001）, that Yangxu town was higher than Wangdian town,ship （x^2=32. 116, P d0. 001）, that Wangdian township was higher than Nabi village （x^2 =30. 488, P 0.001）, and there was no statistically significant difference of Yongle town and Wangdian township （x^2= 5. 952, P = 0. 015〉0. 008）. The detection rate of Strongyloides stercoralis larva was higher than that of whipworm eggs （x^2 = 15.000, P 〈0.001〈0. 017） ; there was no statistically significant difference of the detec- tion rates of Ascarid eggs and whipworm eggs （x^2 =5. 400, P =0. 020〉0. 017）, and of Ascarid eggs and Strongyloides stercoralis larva （x^2=2. 660, P = 0. 103）. The detection rate of Ascarid eggs/whipworm eggs from the soil around the toilet was higher than that from the soil in the garden （x^2 =4. 728, P 〈0.05）. Con- clusion Soil--borne nematode pollution existed in the peripheral locality soils around Baise city, which indica- ted that the harmless management of excrement should he strengthened to reduce the soil pollution of soilborne nematode.
