摘　　要：在丽江市古城区开展了1年、3年、5年、7年生的不同林龄核桃幼树林间作白及的试验研究,调查白及种植3年以后的生长情况,分析不同林龄核桃林间作对白及产量及块茎数的影响。结果表明,白及产量随核桃林龄的增加呈先升高再降低的趋势;块茎数随林龄的增加呈上升趋势,但各组之间差异不显著。文中对整地种植、抚育管理、适时追肥、水分管理、病虫害防治、繁殖方法等白及栽培技术进行了阐述。The experiment of intercropping Bletilla striata in 1-year-old,3-year-old,5-year-old and 7-year-old Juglans sigillata young plantations was carried out in Gucheng District of Lijiang City to investigate the growth of Bletilla striata after 3 years of planting,and to analyze the effects of intercropping on the yield and tuber number of Bletilla striata.The results showed that with the increase of walnut forest age,the yield of Bletilla striata increased first and then decreased,while the number of tubers increased but without significant difference among the groups.This paper also described the cultivation techniques of Bletilla striata from soil preparation,tending management,timely topdressing,water management,pest control and propagation methods.
