细辛原系林荫下野生的一种植物。多分布在阔叶林、针叶林或混交林下。常见于密集的灌木丛间、山沟低湿地方。我省为了解决野生变家种的问题,从1959年起坚持生产与科研相结合,认真总结药农经验,推动了大面积生产的发展。到目前,全区细辛栽培面积已扩大到4200多亩。其中风城县鸡冠山公社袁家沟药材队和宽甸县双山子公社双山子药材队,1978年春曾因此受到全国科技大会的表彰。现把初步摸索到的林下栽培细辛的经验介绍如下:一、林下选地:以选择阔叶林为最好,土层深厚,土质肥沃。阴坡、阳坡,坡度大小均 Asarum is a plant that grows wild under the shade of trees. Mostly distributed in broad-leaved forests, coniferous forests or mixed forests. Common in dense bushes, ravines and low humidity areas. In order to solve the problem of wild family changes, the province has been adhering to the combination of production and scientific research since 1959, earnestly summarizing the experience of the pharmaceutical industry and promoting the development of large-scale production. Up to now, the area of ​​Asarum cultivation has been expanded to more than 4,200 mu. Among them, Yuanjiagou medicinal herb team of Jiguanshan Commune in Fengcheng County and Shuangshanzi medicinal herb team of Shuangshanzi Commune of Kuandian County were honored by the National Science and Technology Conference in the spring of 1978. The preliminary experience of the understory cultivation of Asarum is now described as follows: First, under the forest selection: to choose the broad-leaved forest as the best, deep soil, fertile soil. Shade slope, sunny slope, slope size
