摘　　要：为保护草珊瑚资源,提高杉木人工林的经济效益,在杉木林分间伐后仿野生种植草珊瑚。经过多年的实践探索形成了一套杉木林下草珊瑚种植关键技术体系,包括适生条件、种苗培育、林地准备、林下栽植、栽后管理和采收等环节。适生条件方面,草珊瑚喜温暖湿润环境、忌强光直射,喜林内漫射光。种苗培育方面,生产上多用种子繁殖和扦插繁殖进行种苗培育,种子繁殖过程包括种子采集与处理、苗床准备、播种和苗圃管理;扦插繁殖包括扦插前准备、扦插和扦插后管理等环节。林地准备和林下栽植方面,草珊瑚林下套种宜选择土壤肥沃,微酸性或中性,靠近水源的林地,郁闭度以0.5~0.6为宜;在春季2—4月,选择阴天或雨后土壤湿润时种植。栽后管理方面,包括补植、松土除草、追肥和合理控光等田间管理环节,通过加强管理、施用70%代森锰锌可湿性粉剂等药剂防治病害,采取人工捕捉或利用灯光诱捕虫害。采收环节,该植物选择在晴天露水干后采收,采收后及时洗净晒干或烘干,置于通风干燥处储藏。该种植技术为相关地区林下种植草珊瑚提供参考。To protect the resources of Sarcandra glabra and enhance the economic benefits of Cunninghamia lanceolata plantations,Sarcandra glabra is cultivated in a wild-simulated manner after thinning the Cunninghamia lanceolata stands.Through years of practical exploration,a key technical system for cultivating Sarcandra glabra under Cunninghamia lanceolata forests has been established,including suitable growth conditions,seedling cultivation,land preparation,understory planting,post-planting management,and harvesting.In terms of suitable growth conditions,Sarcandra glabra prefers warm and humid environments,avoids direct strong sunlight,and thrives under diffused light within forests.In terms of seedling cultivation,seed propagation and cutting propagation are commonly used for seedling cultivation.The seed propagation process involves seed collection and treatment,bed preparation,sowing,and nursery management,while cutting propagation includes pre-cutting preparation,cutting,and post-cutting management.In terms of land preparation and understory planting,it is advisable to select the forest land with fertile,slightly acidic or neutral soil and close to water source,and the canopy density should be 0.5-0.6.In spring from February to April,choose cloudy days or when the soil is wet after rain.Post-planting management includes replanting,soil loosening,weeding,fertilization,and light control.Enhanced management practices involve applying 70%mancozeb wettable powder and other agents to control diseases,as well as using manual trapping or light trapping for pest control.The plant is harvested on sunny days after the dew has dried.Harvesting link,after harvesting,it is promptly cleaned,sun-dried or dehydrated,and stored in a ventilated and dry place.This cultivation technique provides a reference for under-forest planting of Sarcandra glabra in relevant areas.
