杜仲以树皮入药,过去一贯采取伐木取皮,每株杜仲只能剥一次皮,使资源受到很大破坏。我所中药科经过多年的实验,采用环剥技术,使树皮再生,可连续剥皮2～3次,取得了很高的经济效益。现将环剥及加工技术介绍如下。 (一)开剥树龄及时间 定值10年以上杜仲,可进行树枝剥皮;定植15年以上,可进行树干剥皮。每年4～6月均可开剥,这时树木水分充足,树干与皮能正常分离。选晴天上午10时以前,下午3时以后开剥;阴天可以全天进行。
Eucommia to the bark of medicine, the past has always taken the logging to take the skin, each plant can only be stripped of Euphorbia skin, so that resources have been greatly damaged. After years of my Chinese medicine Branch of the experiment, the use of girdling technology to regenerate the bark, skin can be stripped 2 or 3 times, and achieved high economic benefits. Now girdling and processing technology are as follows. (A) Peeling open age and time value of more than 10 years Eucommia, branches can be peeled; planting more than 15 years, for trunk peeling. April to June each year can be stripped, when sufficient water trees, tree trunks and skin can be properly separated. Select sunny before 10 o’clock in the morning, after 3 pm peeling; cloudy day can be carried out.
