目的探索适合山丘地区的灭螺方法。方法采用单纯灭螺法、复合灭螺法和改良灭螺法分别对1000 m2的有螺面积进行灭螺,比较3种灭螺方法的用工投入和1年后的灭螺效果,并于2006年和2007年采用改良灭螺法进行了扩大灭螺试验。结果单纯灭螺法、复合灭螺法和改良灭螺法的用工投入分别为1.5、75工和22工;1年后有螺面积压缩率分别为25%、100%和100%;改良灭螺法扩大灭螺有螺面积压缩率为96.48%,以往单纯灭螺法的灭螺效果为36.47%,改良灭螺法的灭螺效果比单纯灭螺法提高了164.54%。结论单纯灭螺法因效果差而不可取;复合灭螺法投入大,且易损坏农田设施,很难广泛应用;改良灭螺法投入适中,简单易行,效果理想,可广泛应用于山丘地区灭螺。
Objective To explore the snail-killing method suitable for hill areas. Methods The methods of simple molting method, compound molting method and modified molting method were respectively used to kill snail area of 1000 m2. The labor input of three molting methods and the molluscicide effect of one year later were compared. In 2006 And in 2007 the use of improved method of eliminating snails to expand the snail test. Results The labor inputs of simple molluscicide method, composite molting method and modified molting method were 1.5, 75 and 22 respectively; after 1 year, the compressive rates of spiral area were 25%, 100% and 100% respectively; Law to expand snail snail area compression rate of 96.48%, the past, the simple method of snail snail molluscum elimination effect of 36.47%, improved snail snail molluscicide effect than simply snail snail method increased 164.54%. Conclusion The method of eliminating mollusc is not desirable due to the poor effect. The method of compound molluscone is difficult to be widely applied because of its large input and easy damage to farmland facilities. The improved method of molluscicide has the advantages of moderate input, easy operation and ideal effect and can be widely used in hills Area snail.
