镶巴县地处大巴山西部,有43个乡,总面积4792万米~2范围内均有野生竹荪生长(以短裙竹荪为主),但以海拔540—890米的巴山南坡嘉陵江永系为竹荪集中产区,从5月下旬菌蕾陆续大量发生,6月下旬开始采摘,7—9月是采摘高峰期,至10月中下旬结束.一般竹林都有生长,但以枯歇的老竹林及死竹蔸周围生长最盛.现将笔者从1987年春开始对巴山南坡野生竹荪集中产区的生态环境实地考察的结果简报如下:(一)营养:竹荪是生长在竹林地中,在竹叶腐殖质层厚处最多,可知其主要营养是纤维素、半纤维素、碳水化合物,有机氮、矿物元素和一些微量元素、无机盐.
Muba County is located in the western part of Daba Mountain, with 43 townships, with a total area of 47.92 million meters ~ 2 have wild Dictyophora growth (mainly Diantan Dictyophora), but the elevation of 540-890 meters of Bashan southern slope Jialing Jiang Yong Department of Dictyophora concentrated areas, from late May bacterial leachate occurred in large numbers, beginning in late June picking, July-September is the peak picking period, to the end of mid-October .General bamboo forests have growth, but to The dead old bamboo forest and bamboo shoots around the growth of the most prosperous now I start from the spring of 1987 on the Bashan southern slope of the wild habitat Dictyophora eco-environmental field survey results are as follows: (a) nutrition: Dictyophora is grown in Bamboo forest, the humus layer thick bamboo most, we can see its main nutrition is cellulose, hemicellulose, carbohydrates, organic nitrogen, mineral elements and some trace elements, inorganic salts.
