北沙参生态农业发展前景分析

Analysis on the Development Prospect of Ecological Agriculture of Glehnia littoralis

该研究概述了北沙参自然生境、产地分布现况,从光照、土壤、肥料及水分的角度探讨适合北沙参种植的环境因素、施肥原则及灌溉方式;提出北沙参种植业劳作强度高、化肥和农药投入量大等问题,且无限制的采挖及生境破坏造成北沙参野生资源严重破坏,北沙参种植业迫切需要实现“产业生态化”;在北沙参生态农业的基础上,探讨新阶段、新格局、新理念下北沙参产业生态化的可行方案。

The growing environment of wild Glehnia littoralis and planting areas of Glehnia littoralis were summarized,and the environmental factors,fertilization principles and irrigation methods were discussed from perspectives of light,soil,fertilizer and water.The planting of Glehnia littoralis had problems such as high labor intensity,large input of chemical fertilizers and pesticides.Serious ruin to the wild resources of Glehnia littoralis was caused by unrestricted picking and damage to growing environment of wild Glehnia littoralis.Glehnia littoralis planting industry urgently should be transformed into ecological industry.Finally,on the basis of ecological agriculture of Glehnia littoralis,from the new stage,new pattern and new concept,the feasible solutions for the ecological development of Glehnia littoralis industry were discussed.
