【摘要】 厘清2021—2024年赫山区稻田福寿螺的发生动态，分析赫山区稻田福寿螺防控中采取的措施、产生的效果及存在的问题，并提出相应对策建议，以期为赫山区科学防控稻田福寿螺提供一定参考，推进水稻产业高质量发展。2021—2024年赫山区稻田福寿螺由河湖区向山丘区蔓延，发生面积、危害面积逐年扩大，危害率由69.20%上升至80.97%。赫山区稻田福寿螺防控措施按田间防效从高到低排列依次为化学防治(91.58%，优秀)、生物防治(78.70%，良好)、物理防治(69.84%，良好)、农业防治(46.33%，一般)。赫山区稻田福寿螺入侵态势得到有效控制，但防控工作仍然存在一些问题：防控区域协调不足；防控时间未覆盖全周期；防控技术存在弊端。在此基础上，提出加强赫山区稻田福寿螺防控的对策建议：建立多部门联防联控机制，完善社会公众群防群治网络；分阶段地开展全年度防控，建立福寿螺常态化监测预警机制；建立福寿螺综合防控示范区，强化福寿螺防控专项资金保障。更多还原

【Abstract】 The study clarified the occurrence dynamics of Pomacea canaliculata in paddy fields of Heshan District from 2021 to 2024,analyzed the measures taken,effects produced and existing problems in the prevention and control of P.canaliculata in paddy fields of Heshan District,and put forward corresponding countermeasures and suggestions,so as to provide certain references for the scientific prevention and control of P.canaliculata in paddy fields of Heshan District and promote the high-quality development of the rice industry.From 2021 to 2024,P.canaliculata in paddy fields spread from the river and lake areas to the mountainous and hilly areas of Heshan District,with the occurrence area and damage area expanding year by year,and the damage rate rising from 69.20% to 80.97%.The prevention and control measures for P.canaliculata in paddy fields of Heshan District,ranked from high to low in terms of field efficacy,were chemical control (91.58%,excellent),biological control (78.70%,good),physical control (69.84%,good),and agricultural control (46.33%,average).The invasion of P.canaliculata in paddy fields of Heshan District was effectively controlled,but there were still some problems in the prevention and control work:the coordination among the prevention and control areas was insufficient;the prevention and control period did not cover the entire cycle;there were drawbacks in the prevention and control technologies.Hence,countermeasures and suggestions for strengthening the prevention and control of P.canaliculata in paddy fields of Heshan District were put forward:to establish a multi-department joint prevention and control mechanism,and to improve the public’s mass prevention and control network;to carry out the full-year prevention and control in phases,and to establish a regular monitoring and early warning mechanism for P.canaliculata;to establish a demonstration zone of P.canaliculata’s comprehensive prevention and control,and to strengthen the guarantee of special funds for the prevention and control of P.canaliculata.更多还原
