摘　　要：福寿螺为害水稻主要表现在秧苗期，由于其产卵量大、孵化率高，一旦在秧田建立种群，将会对水稻秧苗的生长造成很大影响。严重降低水稻育秧期的成苗率和秧苗素质，对粮食生产造成危害。本试验通过设置多个不同螺口密度的处理观察了秧苗的受害差异情况。讨论了螺口密度和秧苗成苗率两个变量间的直线回归及相关性，分析了福寿螺种群密度对水稻秧苗成苗率的影响。为进一步做好稻田福寿螺的预测预报和防治工作提供了依据。The apple snail damages rice plant mainly in seedlings. Because of large amount of eggs and high hatchingrate, rice seedling growth will be greatly damaged once the snail establishes its population in the field. In order to reduce severe snail disasters on rice production, experiments have been done by setting up different density of snail population, to observe the damage results. Discussions are made for effect of snail density on survival rate of rice seedling in nursery. Other- wise, density of snail population and rate of rice seedling in two variables of linear regression and correlation, are also analyzed. Further prediction and treatment on apple snail in rice fields are discussed.
