目的探索特殊有螺环境(特殊环境)的高效灭螺方法。方法 2006年对乱石溪滩、渗水荒山等大面积特殊环境,采用挖掘机进行一次性深挖深埋灭螺(机埋灭螺),灭螺后,连续7年观察灭螺效果,并与2005年采用春、秋两季人工铲草土埋2次、药杀8次的灭螺方法(人工灭螺)的效果和成本进行比较。结果 2006年采用机埋灭螺法,投入为0.78元/m2,有螺面积压缩率达100%;2005年采用人工灭螺法,投入为1.34元/m2,有螺面积压缩率为20.26%。机埋灭螺比人工灭螺投入降低41.79%,灭螺效果提高79.74%。结论大面积特殊环境采用机埋灭螺优于人工灭螺。
Objective To explore the efficient method of snail elimination in special snail environment (special environment). Methods In 2006, aiming at a large area of special environment such as rocky shoal beach and water seeping barren hills, the excavation was carried out by deep excavation of deep-buried snails (burying snail) and snail-killing after excavation for 7 consecutive years. In 2005, the spring and autumn artificial shoveling buried 2 times, killing 8 times to kill the snail method (artificial snail) effect and cost were compared. Results In 2006, the machine was used to destroy the molluscum, the investment was 0.78 yuan / m2, and the compression rate of snail area was 100%. In 2005, it was 1.34 yuan / m2 with the artificial method of eliminating molluscs, and the compression rate of snail area was 20.26%. Machine buried snail than artificial mollusc into the input to reduce 41.79%, snail effect increased 79.74%. Conclusion Large areas of special circumstances machine buried snail better than artificial snail.
