“…Compared with the single-species Pr litter treatment, the Pr + Cj treatment significantly increased soil MBC by 10.6, 18.4 and 25.7%, and the Pr + Od treatment significantly increased it by 14.7, 20.6 and 30.5% at day 14, 42 and 84, respectively (P < 0.05). The increasing substrate availability underlying the mixed leaf litters may contribute to the increase of soil MBC, which was also observed in the other studies on soil microbial properties responding to the litter mixtures (Hu et al 2006).…”

“…Some studies (Hu et al 2006) have shown that the nutrient availability and soil quality of coniferous stands could be improved by mixing broadleaf litters. Such practices may therefore be considered carrying out to restore soil fertility of pine plantations at our study site.…”

“…The microcosm method was validated to provide a good access for studying the effect of litter type on soil properties during the early stage of decomposition (Taylor and Parkinson 1988, Vargas et al 2006, Wang et al 2010. Since soil microbial biomass, enzyme activities, and DOC were suggested as early indicators of biological changes, and even important indicators of soil quality (Liang et al 1998, Hu et al 2006, Wang et al 2013, this study should provide some valuable information for the soil fertility management of the local pine plantations.…”

A laboratory microcosm experiment was conducted to evaluate the effects of the four single-species (Pinus tabulaeformis (Pt), Pinus radiata (Pr), Cercidiphyllum japonicum (Cj), and Ostryopsis davidiana (Od) litters from southwestern China and mixed pine-broadleaf (Pt + Cj, Pr + Cj, Pt + Od, Pr + Od) litters on soil microbial activities and dissolved organic carbon (DOC). Microcosms with the local typical soil and litterbags containing the eight litter types were incubated with 60% water field capacity for 84 days at 20°C. The results showed that the dynamics of soil microbial parameters and DOC were influenced by the litter types with different initial chemical quality. Due to their initial poor nutrient contents, the Pt and Pr litter treatments always showed lower soil microbial activities and DOC at each sampling compared with the Cj and Od litter treatments. However, compared with the single-species pine litter treatments, the inclusion of broadleaf Cj or Od litter into pine litter significantly increased soil microbial activities, and the concentrations of soil DOC during the whole incubation process. The current work thus provided a good implication for plantation management that it should be appropriate to consider Cj as an ameliorative species or retain Od in the pine plantations to improve soil conditions.

“…Previous studies report that build-up of plant pathogens is one of the major causes in soil sickness in Cistus ladanifer (Hassan et al, 1989), peach (Benizri et al, 2005), cucumber (Yao et al, 2006), Rehmannia glutinosa (Chen et al, 2007), Liriope (Zhao et al, 2010), while autotoxicity has been reported to be one of the major causes in soil sickness in cucurbit crops (Yu et al, 2000), alfalfa (Segiun et al, 2002), Cistus ladanifer (Alías et al, 2006), cucumber (Yao et al, 2006) and wheat (Wu et al, 2007). In many cases, soil microorganism played either direct or indirect role in yield reduction (Manici et al, 2003;Hu et al, 2006). In conclusion, the cause of soil sickness is complex.…”

Aims and Methods A pot experiment was carried out to determine the effect of Angelica sinensis intercropped with garlic on A. sinensis growth and soil microbial communities in rhizosphere soil of A. sinensis under the scheme of A. sinensis intercropped with garlic. Results Soil microbial community was changed and bacteria functional group diversity was increased, and A. sinensis growth was improved when A. sinensis intercropped with garlic under the continuous cropping condition. Also, it shows that intercropping significantly increased root dry weight, and much less substantially shoot dry weight and plant height. Relative to the control, the activity of superoxide dismutase, peroxidase and catalase was increased by 80.00, 243.41 and 37.13%, respectively, but the content of malondialdehyde was decreased by 11.67%, along with a 70.13% yield improvement of A. sinensis, and 50.00% and 10.20% essential oil and alcohol-soluble extract increasing, respectively. The result also showed that the population of bacteria, aerobic cellulose-decomposing bacteria, organic phosphorus-solubilizing bacteria, inorganic phosphorus-solubilizing bacteria and potassium-solubilizing bacteria in rhizosphere soil were promoted in intercropping in vigorous growth stage. The abundance of aerobic cellulose-decomposing bacteria, organic phosphorussolubilizing bacteria and potassium-solubilizing bacteria in intercropping soils changed at the rootstock thickening. Although the total population of functional groups in intercropping A. sinensis rhizosphere soils was lower than in monocroping system, community diversity and evenness increased and dominance concentration decreased. Conclusions Intercropping A. sinensis with garlic can alleviate the soil sickness of A. sinensis.

Carbon accumulation by Pinus sylvestris forest plantations after different periods of afforestation in a semiarid sandy ecosystem

The carbon pool is changing in afforestation ecosystems, which vary in their duration since establishment, in many semiarid sand regions. Understanding this is important for the management of the planted forest. The present study explored the dynamics of afforested forest carbon pool in a semiarid sandy ecosystem, northwest China. We studied afforested forests of pine (Pinus sylvestris) of five afforestation ages (20, 30, 40, 50, and 60 years since planting, and bare sand as control), the carbon storage and carbon sequestration rate of the forest aboveground biomass layer, surface litter layer, and soil layer (0-50 cm) were calculated, and the soil water content and soil organic carbon of 0-400 cm soil depth were measured. The results showed that the carbon sequestration rate was highest after 20-30 years, with 0.58 Mg C ha −1 yr −1 in the soil layer (0-50 cm). We found a rate of 0.13 Mg C ha −1 yr −1 in the surface litter layer, and a rate of 20.79 Mg C ha −1 yr −1 in the forest aboveground biomass layer. The carbon storage of the forest aboveground biomass layer was highest after 30-40 years, and the carbon storage of the surface litter increased with time. In the soil layer, the carbon storage at 0-10 cm depth was highest after 60 years, the carbon storage at 20-50 cm depth increased soon after afforestation and then decreased afterward with increasing afforestation ages with the maximum for 20-50 cm occurring after 30-40 years. The total carbon storage [the forest aboveground biomass layer, surface litter layer and soil layer (0-50 cm)] was higher when afforestation ages reached around 30 years, after that it decreased with increasing afforestation age. Our research improves the understanding of the P. sylvestris forest ecosystem carbon sequestration in a semiarid sandy area.
