4种不同类型林分下仿野生栽培灵芝品质分析

    Analysis on the Quality of Ganoderma Lucidum Cultivated in Imitating Wild Condition Under 4 Different Stand Types

    • 摘要: 为探讨不同林分类型仿野生栽培灵芝技术,以赤芝为试验材料,通过设置马尾松林、竹林、阔叶林和杉木林4种不同林分类型套种灵芝试验,研究分析4种林下仿野生栽培方式对灵芝形态特征、子实体主要活性成分以及重金属含量的影响。结果表明:4种林分类型仿野生栽培模式对灵芝形态特征和子实体物质含量均有显著影响。阔叶林下套种灵芝的菌柄长和菌盖厚度均最大,分别为(9.61±0.16)cm、(16.36±0.44)mm;三萜酸含量、粗蛋白含量及粗脂肪含量最高,分别为(0.58±0.03)%、(22.53±0.33)%、(15.31±0.20)%。杉木林下套种灵芝的菌柄直径和菌盖直径均最大,分别为(12.61±0.22)mm、(11.77±0.08)mm;黄酮含量和总糖含量最高,分别为(0.76±0.02)%、(1.24±0.09)%;除铅含量以外,镉、砷、汞等重金属含量较低。综合分析,阔叶林下和杉木林下套种灵芝的形态特征和品质较好,其铅、镉、砷、汞含量均符合《中华人民共和国药典》限量标准。

       

      Abstract: In order to explore the techniques of cultivating Ganoderma lucidum in different stand types, the experiment of interplanting Ganoderma lucidum in four different stand types, namely Masson pine forest, bamboo forest, broadleaf forest and Chinese fir forest, was carried out by taking Ganoderma lucidum as the test material, thus to study and analyze the effects of the 4 bionics wild cultivation patterns on the morphological characteristics, main active components of fruiting bodies and heavy metal content of Ganoderma lucidum. The results showed that the bionics wild cultivation patterns of four stand types had significant effects on the morphological characteristics of Ganoderma lucidum and the material content of fruiting bodies. The stipe length and pileus thickness of Ganoderma lucidum interplanted under the broadleaf forest were the largest, which were (9.61±0.16) cm and (16.36±0.44) mm, respectively; The contents of triterpene acids, crude protein and crude fat were the highest, which were (0.58±0.03)%, (22.53±0.33)% and (15.31±0.20)%, respectively. The stipe diameter and pileus diameter of Ganoderma lucidum interplanted under the Chinese fir forest were the largest, which were (12.61±0.22) mm and (11.77±0.08) mm, respectively; The contents of flavonoids and total sugar were the highest, which were (0.76±0.02)% and (1.24±0.09)%, respectively; In addition to the lead content, the contents of the heavy metals such as cadmium, arsenic and mercury were all low. Based on the comprehensive analysis, the morphological characteristics and quality of Ganoderma lucidum interplanted under the broadleaf forest and Chinese fir forest were better, and the contents of lead, cadmium, arsenic and mercury in Ganoderma lucidum were all in accordance with the limit standard of the Pharmacopoeia of the People's Republic of China.
