World mushroom production in 2018 was approximately 8.99 million tonnes. The most commonly cultivated species in the Czech Republic are Agaricus spp., which are sold fresh or canned. In 2017, 2018 mushroom production in the Czech Republic was approximately 540 tonnes. Vermicomposting is an easy and less ecologically harmful way to process the spent mushroom substrate. Earthworms, which are referred to as the engine of the process of vermicomposting, and microorganisms, help convert organic waste into fertilizer. This study is concerned with laboratory vermicomposting in a system of continuous feeding of earthworms Eisenia andrei. It compares the differences between variants with and without earthworms. The dry matter percentage was approximately 20% or more in both variants. The variant with earthworms showed a significant decrease in electrical conductivity. The C/N ratio was very low in both variants. The highest total P was recorded in the variant with earthworms, but the highest values of K and Mg were found in the control. Both variants recorded higher content of bacteria than fungi. All values of microorganism contents were higher in the vermicomposter without earthworms, but the bacterial/fungal ratio was higher in the variant with earthworms. The highest content in both variants shows the bacteria especially G-bacteria, on the other side, the lowest content shows the actinobacteria. The highest activity of β-D-glucosidase and acid phosphatase was measured in the vermicomposter with earthworms, but the activity of other enzymes was higher in the control. In both vermicomposters laccase activity was below the detection limit. The method of classical vermicomposting can be used for processing the spent mushroom substrate. However, in terms of higher content of total and available nutrients, there seems to be a better method of processing the substrate without earthworms.

使用姬松茸蘑菇底物进行实验室堆肥的层数变化。

2018年世界蘑菇产量约为899万吨。捷克共和国最常见的栽培种是姬松茸,可以新鲜或罐装出售。2017年,捷克共和国2018年蘑菇产量约为540吨。com堆肥是处理用过的蘑菇基质的一种简单且对生态不利的方法。ver,被称为ver堆肥过程的引擎,以及微生物,有助于将有机废物转化为肥料。这项研究涉及laboratory连续饲喂系统中的实验室ver堆肥。它比较了有和没有without的变体之间的差异。在两个变体中,干物质百分比约为20%或更高。with的变体显示出电导率显着降低。两种变体的C / N比都非常低。with的变种中记录到最高的总磷,但在对照中发现最高的K和Mg值。两种变体记录的细菌含量均高于真菌。在没有without的ver生堆中,微生物含量的所有值都较高,但在有variant的变体中,细菌/真菌的比率较高。两个变体中含量最高的是细菌,尤其是G细菌,另一方面,含量最低的是放线菌。β-D-葡糖苷酶和酸性磷酸酶的最高活性是在comp生的comp堆中测得的,而其他酶的活性则在对照组中更高。在这两种ver生动物中,漆酶活性均低于检测极限。经典的com堆肥方法可用于处理用过的蘑菇基质。但是,就总营养素和可用营养素的含量较高而言,似乎有一种更好的无processing处理基质的方法。
