环剥技术早已用于杜仲树,比伐倒一次剥皮总体上提高产量4～9倍。1992年,我们将此法试用于名贵中药材黄柏。小区试验结果,成活率百分之百,取得极好效果。具体做法如下:1 掌握环剥时间黄柏与杜仲一样,最关键的因素之一就是“剥适其时”。过早过晚都会造成损失。过早温度低,湿度不够,容易使剥过皮的树干脱水,影响成活;过晚则雨季已过,昼夜温差大,白天光照强,不利再生树皮形成。最好的时间是夏至前几天至中伏,即6～7月份。2 环剥步骤 (1)选好候剥植株,在树干分支下面环切一刀,在距地面3厘米处再环切一刀,在两环割圈间纵切一刀,便成“工”字形;(2)在上环切口与
Girdling technology has long been used in Eucommia ulmoides, bark cutting down an overall increase in yield 4 to 9 times. In 1992, we try this method for valuable Chinese herbal medicine cork. Cell test results, one hundred percent survival rate, achieved excellent results. Specific practices are as follows: 1 grasping the girdling time Cork and eucommia, one of the most critical factor is “stripping time”. Too early or too late will result in loss. Premature low temperature, humidity is not enough, easy to peel off the trunk of the trunk dehydration, affecting survival; too late then the rainy season, day and night temperature difference, light during the day strong, adverse regeneration bark formation. The best time is a few days before the summer solstice to the volts, that is, from June to July. 2 girdling steps (1) Select the stripped plants, cut in the trunk below the knife, 3 cm away from the ground and then re-cut a knife, cut between the two rings slitting a knife, it becomes ; (2) cut in the ring and
