近年来,原木灵芝栽培技术逐渐成熟,但仍存在一些问题,其中以菌木发菌期杂菌污染问题较为突出,造成菌木成品率低,直接影响到灵芝的产量和质量。因而对杂菌种类进行分析,是提高菌木成品率的一项有意义工作。笔者经过两年生产实践、观察,现就菌木受污染时表现特征作如下分析。 (一)杂菌污染初期表现不明显,中后期菌木逐渐由白变绿,杂菌菌丝密集,产生绿色粉状物,灵芝菌丝逐渐死亡,整根菌木会被污染,剖开菌木在空隙有绿色
In recent years, the cultivation technology of log Ganoderma lucidum has gradually matured, but some problems still exist. Among them, the problem of bacterial contamination by the fungus is more prominent, which leads to the low yield of the fungus and directly affects the yield and quality of Ganoderma lucidum. Therefore, the analysis of the types of bacteria is to improve the yield of the fungus a meaningful work. After two years of production practice, the author is now on the performance characteristics of the fungus contaminated for the following analysis. (A) the initial performance of bacterial contamination is not obvious, in the late Bacillus gradually white from green, bacteria dense mycelium, resulting in green powder, Ganoderma lucidum hyphae gradually death, the entire root bacteria will be contaminated, cut open bacteria Wood in the gap with green
