摘　　要：为加强野生苏铁资源保护,丰富福建沙县地区四川苏铁种群数量,改善当地该物种的群落生存环境。基于该物种保护实践,总结了其救护和繁育技术,主要包括就地保护与移植繁育2种措施。就地保护包括选择生长健壮、叶冠茂盛的母树,开沟穴施复合肥或腐熟饼肥,针对发生的病虫害种类因地制宜采取防治措施,开展生长调查和建立技术档案;移植繁育包括选择与原生长环境相似的移植地,安装灌溉系统,选择生长健壮的移植母株、带土挖出,栽植后浇足定根水、及时开展病虫害防治等措施。通过以上措施可改善野生四川苏铁群落生存环境,增加其种群数量,达到救护该物种的目的。本文为建设以救护、科学研究和推广示范为一体的集约化、产业化苏铁资源保护基地提供参考。To strengthen the protection of wild Cycas revoluta resources,enrich the population of Cycas szechuanensis in Shaxian District of Fujian Province,and improve the living environment of local wild Cycas szechuanensis communities.Based on the protection practice of Cycas szechuanensis,its rescue and breeding techniques have been summarized,mainly including 2 measures:in situ protection and transplantation breeding.In situ protection includes selecting mother trees that grow strong and have lush leaf crowns,applying compound fertilizer or decomposed cake fertilizer in trenches and holes,taking appropriate prevention and control measures for the types of pests and diseases that occur locally,conducting growth surveys,and establishing technical archives;transplantation breeding includes selecting transplant sites that are basically consistent with the original growth environment,installing irrigation systems,selecting healthy transplant mother plants,digging out soil,watering roots thoroughly after planting,and timely carrying out pest and disease control measures.Through these measures,the living environment of wild Cycas szechuanensis populations can be improved,the population of Cycas szechuanensis can be increased,and the goal of rescuing Cycas szechuanensis can be achieved.This article provides references for the construction of an intensive and industrialized Cycas szechuanensis resource protection base that integrates rescue,scientific research,and promotion demonstration.
