目的探索2种冬种作物水旱轮作对来年早稻田福寿螺的控制效果及对水稻产量的影响。方法对冬种马铃薯和冬种黑麦草这2种控螺方式下前后茬稻田中福寿螺种群和后茬水稻产量进行调查，并与冬闲干田和冬闲淹水处理的前后茬稻田进行对比。结果和结论冬种马铃薯能够有效减少来年早稻田福寿螺的发生量，且能提高来年早稻产量，但早稻生长后期福寿螺种群恢复速度加快。冬种黑麦草处理的控螺效果不理想，但有利于来年早稻增产。冬种水旱轮作模式下对福寿螺卵块的控制效果不明显，但在来年早稻种植的初期，绝大部分卵块产在田埂杂草上且数量较少，此时人工摘卵较为方便省时。

Objective]To investigate the influence of paddy-upland rotation on controlling Pomacea canal-iculata and rice yield.[Method] Four farming measures including winter potato rotation system , winter ryegrass rotation system , and two winter fallow rice fields treatments with water cover or without any water cover ( two controls ) were employed .The field population structure of snails in the previous and subse-quent rice field , and early rice yield in the subsequent season were investigated .[Result and conclusion]The results showed that winter potato rotation treatment was helpful for snails control and rice yield in-crease in the subsequent farming season , but the snail population recovery accelerated in the early rice growing period because of this rotation treatment .Winter ryegrass rotation treatment was unsatisfactory for snails control while it was beneficial for the early rice output of the next season .Winter-planting rotation was negative for controlling snail eggs , while the eggs were relatively few and most of them were distribu-ted on weeds along field ridges .The eggs could be collected conveniently and efficiently at the beginning of the early rice growing season .
