黄柏又名黄檗,属芸香科落叶乔木。树皮为常用中药,有泻火解毒、清湿热的功能,可治疗尿路感染前列腺炎、黄疸、肠炎、白带湿疹等疾病。过去,剥取黄柏树皮,都是将树木砍倒剥皮,这是一种“杀鸡取卵”的办法。虽然每年大力栽培发展,但因黄柏树木生长周期一般要10～15年,柏皮供求矛盾一直没有解决。为缩短柏皮生长利用周期,保护和增加药材资源,我们在1980～1982年间,连续进行了三年环剥试验,共环剥230株,成活率由1980年的33％提高到1981年的52％和1982年的78％。在最佳季节(5、6两月)环剥,三年平均成活率达90％以上,且再生新皮生长良好。现将黄柏环剥技术简介如下: 1、选择适宜的环剥季节和天气条件。在 Phellodendron, also known as Huangqi, is a deciduous tree of Rutaceae. Bark is a commonly used traditional Chinese medicine. It has the functions of purging fire, detoxifying, clearing dampness and heat, and can treat urinary tract infections such as prostatitis, jaundice, enteritis, leucorrhea and eczema. In the past, stripping the cork bark was to cut down and peel the tree. This is a way to “kill chickens and take eggs”. Although the cultivation and development are vigorously carried out every year, due to the growth cycle of the Phellodendron chinense trees usually takes 10 to 15 years, the contradiction between the supply and demand of cypress has not been resolved. In order to shorten the cycle of growth and utilization of medicinal plants and to protect and increase medicinal resources, we conducted three years of circumcision trials from 1980 to 1982. A total of 230 circumcision trials were performed. The survival rate increased from 33% in 1980 to 52 in 1981. % and 78% in 1982. In the best season (five or six months) girdling, the average survival rate is more than 90% in three years, and the regeneration of fresh skin is good. The cork circumcision technology is summarized as follows: 1. Select the appropriate girdling season and weather conditions. in
