| 摘 要： | 目的 为森林防火和枯枝落叶的循环利用,筛选和优化菌株,并应用于防火林带景观树种枯枝落叶的降解。 方法 采用树种枯枝落叶叶片条降解法、降解失重法筛选出强降解菌株,再比较强降解菌株混合联用的降解失重效果,选出强降解菌株的混合联用组合,并分析其对枯枝落叶的降解效果和作用。 结果 通过比较11菌株对12种防火林带景观树种枯枝落叶的降解效果,筛选出绵皮卧孔菌 (Pp)、康宁木霉(Tk1)和云芝(Pv)等3株强降解菌株;3菌株单用及联用对檫树、红叶石楠和木荷枯枝落叶降解失重率分别为54.3% ± 2.3%和62.1% ± 3.3%。 结论 筛选出的3菌株单用及联用组合,Pp + Pv、Pv + Tk1和Pp + Tk1对防火林带景观树种枯枝落叶有明显的降解效果,可用于苏南丘陵山区的防火和枯枝落叶处理工作。

| Abstract: | Objective To screen and optimize the strain and apply it to the degradation of dead leaves of landscape tree species in forest firebreak belt for recycling of dead leaves and forest fire prevention. Method The highly degrading strains were screened out by the degradation methods of leaf strips of tree species in color bio-fireproof forest belt and the degradation weight loss methods. The highly degrading strains and their combinations were selected by the experimental analysis of the degradation weight loss effect of the highly degrading strains and their combinations. In addition, their degradation rules on the dead branches and leaves were analyzed. Result Through the degradation experiments of 11 strains on deciduous leaves and dead branches and leaves of 12 colorful landscape trees in the firebreak belt, Postia Placenta (Pp),Trichoderma Koningii (Tk1) and Polystictus versicolor (Pv) were found to have strong degradation ability and weight loss effect. The weight loss of Sassafras tsumu, Photinia × fraseri and Schima superba were 54.3% ± 2.3% and 62.1% ± 3.3% respectively. Conclusion Pp + Pv, Pv + Tk1 and Pp + Tk1 have significant degradation effect on the tree species in the forest firebreak belts, which can be widely used as in the forest firebreak belts in the south of Jiangsu Province. |
