辽东山区黄檗人工林环剥经营技术研究

Study on Ring Stripping Management Technology of Phellodendron amurense Plantation in Mountainous Area of Eastern Liaoning

以辽东山区黄檗人工林为研究对象进行环剥试验,确定了辽东山区黄檗人工林环剥起始年龄Ⅲ地位级15年,Ⅱ地位级与Ⅳ地位级相应提前和延后1年;最佳环剥季节为5~6月,其树皮再生成功率均值达到95.83%;阴而无雨的天气为环剥最佳天气条件,树皮再生成功率均值可达到95.85%;测算出30年生黄檗单株鲜皮总收获量均值为33.53 kg。

Taking the artificial forest of Phellodendron amurense as the research object,the girdling experiment was carried out,and the key points of girdling technology were summarized.The starting age of girdling of Phellodendron amurense plantation was determined for 15 years,the Stage II and stage IV of girdling were advanced and delayed for one year,the best girdling period was 5~6 months,and the average success rate of bark regeneration was 95.83%The successful rate of bark regeneration could reach 95.85%when the weather was overcast without rain,and the average value of fresh bark yield of 30-year-old Phellodendron amurense was 33.53 kg.
