摘要:
为探讨内生真菌在凋落叶分解过程中的作用,将杉木分离纯化的3株真菌CG2青霉属(Penicillium)(A菌)、AY13黄色镰刀菌(Fusarium culmorum)(B菌)、AJ14踝节霉菌(Talaromyces)(C菌)作为分解菌株,以菌丝、灭菌发酵液以及单菌和混菌的方式添加到装有杉木凋落叶的盆钵中,同时设置未添加真菌的对照(CK)处理,研究了杉木凋落叶在不同菌株调控下10 d、30 d、60 d、90 d以及120 d内的分解动态。结果显示,A菌液处理在120天内凋落叶质量损失率最高,而AC菌丝处理60 d时与对照存在显著差异(P<0.05),比对照高23.97%;60 d,凋落叶碳含量在A菌丝处理下与对照有显著差异(P<0.05),比对照低16.74%,而B菌丝处理90 d时含量最低,比对照低21.13%,大部分菌株处理下氮含量较对照增加,其中A菌液处理下氮含量与对照有显著差异(P<0.05),比对照高17.05%,与氮元素相似,磷含量同样增加,A菌丝处理与对照有显著差异,比对照高46.67%,而钾含量在C菌液处理下比对照低28%,与对照存在显著差异;90 d,碳氮比在A菌丝和B菌丝处理下数值最低,分别比对照低25.54%和25.11%,且都与对照有显著差异(P<0.05),而A菌丝处理60 d时碳磷比最低,与对照有显著差异(P<0.05),比对照低43.05%。结果表明,3株内生真菌对杉木凋落叶质量损失率、养分含量的影响不同,A菌株对凋落叶质量损失和养分含量影响明显,对杉木菌肥的选育有参考价值。(图7 表7 参43)
Abstract:
In order to study the degradation of the Cunninghamia lanceolate leaves by endogenous fungi, Three strains of fungi isolated from Chinese fir: Penicillium (A), AY13 Fusarium culmorum (B), and AJ14 Talaromyces (C) were used as experimental fungi. Endophytes were poured into experimental pots using mycelium, sterile fermentation broth and single fungi and mixed fungi, and control (CK) treatment with no fungi added, The change of quality loss rate and nutrient content was studied on 10 d, 30 d, 60 d, 90 d and 120 d. T he results showed that During the 120 days of the experiment, the loss rate of leaf litter in group A was the highest, In the mycelia treatment, mycelia in group AC was significantly different from the control on the 60th day (P<0.05). mycelia AC was 23.97% higher than the control. On the 60th day, the content of carbon in leaf litter in group A was 16.74% lower than the control. The carbon content was the lowest at 90 days under B hyphae treatment, which was 21.13% lower than the control, The nitrogen content of most mycelia treatments was higher than the control. and the group A was significantly different from the control (P<0.05), 17.05% higher than the control, Similar to nitrogen, phosphorus content was higher than the control, In the mycelia treatment, mycelia A was significantly different from the control. On the 60th day (P<0.05). which was 46.67% higher than the control. The potassium content was 28% lower than the control under the treatment of bacteria C and there was a significant difference from the control. at 90 d, the ratio of carbon to nitrogen in group A and group B was the smallest, Group A was 25.54% lower than control, Group B was 25.11% lower than control, The ratio of carbon to phosphorus in group A was the minimum on the 60th day, which was 43.05% lower than the control, This study further revealed the effects of three endophytic fungi on the quality loss rate, nutrient element and stoichiometry of litter fall were different, FungusA can improve mass loss rate and p romote the return of nutrients mostly , The results of this research provide useful references for breeding of Chinese fir fertilizer.
