通过对茭白田福寿螺进行摘卵捡螺、捡螺不摘卵、摘卵不捡螺和不摘卵不捡螺4种方法处理,并就4种方法对福寿螺危害的控制作用进行比较。结果表明,摘除卵块或者直接捡去田间成、幼螺,能有效地减轻福寿螺对茭白的危害,摘卵捡螺的效果最好,苗蘖受害率比其他3种方法低4.56%～2.13%,丛高受害率低7.91%～0.39%,产量损失率下降6.77%～2.17%。 Four methods were used to deal with the control effects of four kinds of methods on the harm of snakehead snail by picking the snail eggs, picking the snails without picking the eggs, picking the eggs without picking the snails and picking the eggs without picking the eggs. The results showed that the removal of egg masses or the direct seeding of field snails and young snails could effectively reduce the harm of snails to snails. The picking of snails was the best and the rate of seedling tillers was 4.56% -2.13% lower than that of the other three methods. Plexus high damage rate of 7.91% ~ 0.39%, the yield loss rate decreased 6.77% ~ 2.17%.
