Dear Editor,The transition from the vegetative to the reproductive phase of plant development,known as the floral transition,plays important roles in the plant life *** is a vulnerable but crucial phase for building crop yield,and proper timing of this period is therefore vital for obtaining optimal yields(Jung and Muller,2009).Analysis of flowering time is currently an important research topic in several fields,including plant molecular genetics,evolutionary biology,ecology,and crop breeding(Huang et al.,2011).

Plant diversity significantly impacts ecosystem processes and functions, yet its influence on the community assembly of leaf fungi remains poorly understood. In this study, we investigated leaf epiphytic and endophytic fungal communities in a Chinese subtropical tree species richness experiment, ranging from 1 to 16 species, using amplicon sequencing to target the internal transcribed spacer 1 region of the rDNA. We found that the community assembly of epiphytic and endophytic fungi was predominantly governed by stochastic processes, with a higher contribution of dispersal limitation on epiphytic than on endophytic fungal communities but a higher contribution of selection on endophytic than on epiphytic fungal communities. The plant-epiphytic fungus interaction network was more complex(e.g., more highly connected and strongly nested but less specialized and modularized) than the plant-endophytic fungus interaction network. Additionally,tree species richness was positively correlated with the network complexity and diversity of epiphytic(α-, β-and γ-diversity) and endophytic(β-and γ-diversity) fungi, but was not associated with the contribution of the stochastic and deterministic processes on the community assembly of epiphytic and endophytic fungi. This study highlights that tree species diversity enhances the diversity and network complexity,rather than alters the ecological processes in community assembly of leaf-associated fungi.

苏州某通沟污泥处理站存在卸料时间长、操作人员多、管道易堵塞、水消耗量大等问题,对其实施技术改造:将原卸料口的固定钢格栅栅隙由100 mm改为200 mm;新增双轴破碎机,取消喂料抓斗;增加水力旋流器和砂水分离器;将处理后的污水回用到前端供洗涤转鼓、洗砂单元和精细格栅使用。改造后的通沟污泥处理站卸料方便、自动化程度高,减少了3名操作人员,管道不再因细砂而堵塞;降低了水耗,处理水耗由改造前的30 m^(3)/t污泥降至5 m^(3)/t污泥。运行结果表明,改造后的工艺具有运行稳定、自动化程度高、管道不易堵塞、水耗低等特点,可为其他同类项目的建设提供参考。
