当废棉培养料中的Zn含量为29（10~(-8),下同）和47时,草菇子实体富集的Zn量最大.分别为8.5和13.8,呈正相关。当废棉培养料的Zn含量增至268、482和2122时 富集的Zn量分别只有6.9、5.6和3.6,呈负相关。当废棉培养料Zn含量达4350时,草菇不产生或很少产生子实体.菌盖Zn含量（25.1）一般高于菌托和菌柄（8.2和7.9）用~(65)Zn作示踪剂,通过测量放射性活度（cpm/g）和采用放射自显影技术,研究~(65)Zn在菌盖、菌柄和菌托中的吸收与分布,结果同样显示,~(65)Zn在菌盖和菌托中的含量大于菌柄.此外;随着子实体由蛋期到成熟期,菌托和菌柄中的~(65)Zn向菌盖转移.为了探索草菇子实体的“生物活性锌”.测量了草菇子实体的蛋白质沉淀物和上清液的~(65)Zn放射性活度（cpm/g）.结果发现Zn较少与蛋白质结合,较多与可溶性糖和游离氨基酸等结合,或呈游离状态存在.
When the content of Zn in the waste cotton culture material was 29 (10 -8, the same below) and 47, the content of Zn enriched in M. fruiting bodies was the highest, which were 8.5 and 13.8, respectively. When the Zn content of the waste cotton culture material increased to 268,482 and 2122, the amount of Zn accumulated was only 6.9, 5.6 and 3.6, respectively, showing a negative correlation. Straw mushroom did not produce or seldom fruiting bodies when the Zn content of the waste cotton culture material reached 4350. Zn content of the mushroom cap (25.1) was generally higher than that of the bacteriostat and stipe (8.2 and 7.9) with ~ (65) Zn The absorption and distribution of ~ (65) Zn in the capsid, petiole and bacteriostasis were studied by measuring the radioactivity (cpm / g) and using autoradiography. The results also showed that ~ (65) Zn The content of Zn in the capsid and bacteriostasis was higher than that in the stipe. In addition, ~ (65) Zn in the bacteriostat and the bacterium was transferred to the capsid as the fruiting body went from egg age to maturity. “Bioactive zinc.” The radioactivity (cpm / g) of ~ (65) Zn in protein precipitate and supernatant of Agrocybe pseudoscaniculata fruiting body was measured. It was found that Zn was less bound to the protein and more soluble in soluble sugar and Free amino acids, etc., or exist in a free state.
