由于土壤有机质(SOM)化学结构上的异质性,其对于全球气候变化的响应变得难以预测.随着分子水平技术逐渐应用于SOM结构、来源及分解状态的研究,长久以来关于SOM组分及稳定性的问题可能将被解决.本研究通过两年的减少降雨(50%)处理,运用生物标志物技术,对杉木幼林SOM组分及分解程度进行研究,以探究降水格局的改变对亚热带杉木幼林SOM稳定性的影响.结果表明: 减少降雨处理显著降低了土壤中游离脂质的含量,分别降低了短链烷酸的62.8%和萜类及固醇类含量的19.1%,而对其他脂类无显著影响.尽管短期减少降雨处理并未影响土壤中木质素总量,却显著降低了紫丁香基和香草基的酸醛比值.因此,随着降雨格局的改变,可能加快SOM易分解组分分解.尽管难分解组分(木质素)相对稳定,但从长远来看,其稳定性还需持续监测.

Colletotrichum has a broad host range and causes major yield losses of crops. The fungus Colletotrichum gloeosporioides is associated with anthracnose on Chinese fir. In this study, we present a high-quality draft genome sequence of C. gloeosporioides s.s SMCG1#C, providing a reference genomic data for further research on anthracnose of Chinese fir and other hosts.

对福建南平峡阳林场19年生米老排和杉木人工林的细根进行为期12个月的分解试验,研究不同树种分解过程中养分和微生物群落组成的动态变化,为理解亚热带不同人工林树种地下养分循环过程提供科学依据.结果表明: 米老排细根养分磷(P)、钾(K)初始含量显著高于杉木.分解过程中,两个树种细根P、K含量均显著降低,而细根氮(N)含量显著增加,且杉木细根N含量变化滞后于米老排.在分解过程中,杉木细根镁(Mg)含量无显著变化;米老排细根Mg含量变化显著,且在分解8个月时显著小于杉木.在分解过程中,真菌与细菌比值均显著表现为先升高后降低,且分解12个月时米老排细根真菌/细菌显著高于杉木.冗余分析表明,N(解释37.2%)、K(解释14.5%)含量和C/N(解释14.8%)是影响杉木细根分解过程中微生物群落组成变化的主要养分因子,而Mg(解释35.9%)和K(解释17.6%)含量则是米老排细根分解时影响微生物群落组成的主要养分因子.研究表明,在不同树种中,除了N之外,Mg等其他养分元素也可能是影响根系分解的重要因子.

以木荷和杉木为试验材料,模拟异质和同质两种森林土壤养分环境,设计单植、两株纯植和两株混植3种栽植方式,开展盆栽试验研究木荷与杉木混交造林增产及木荷生长竞争优势形成的原因.结果表明: 与同质养分环境相比,异质养分环境中木荷与杉木混植时两树种均具有较高的苗高和干物质积累量,且木荷竞争优势明显,这与其根系可塑性强有关.混植的木荷各径级细根大量增生,其根系总长度、表面积和体积比杉木高80%~180%.木荷细根在垂直方向上采用了补偿性的生长策略,即除占据富养表层外,还在低养分斑块中大量增殖以获得更大的竞争优势.木荷与杉木的细根在土壤中的拓殖深度不同,生态位分化,缓解了两树种根系对养分的强烈竞争,提高了混植产量.纯植的木荷由于根系自我识别作用,抑制了根系的生长,使得纯植产量较低.细根在空间上错开和均匀分布可能是木荷纯林结构稳定的原因之一.建议在生产中采用块状整地和表层施肥等措施,改善土壤养分分布状况,营建混交林促进木荷和杉木生长,而对已营造的木荷人工纯林,可以及时调控林分密度促进林木生长.
