“…Hook) is an important fast-growing, evergreen coniferous timber species that has been widely planted in southeastern China for more than 1000 years (Chen, 2003). Because of its high commercial value, Chinese fir plantations, which are typically high-density monocultures, have been widely established in previous natural broadleaf forests, and short rotation forestry has become common over the past century in an attempt to meet the rising demand for timber (Tian et al, 2011). These Chinese fir monoculture plantations are carbon sinks, but they are more susceptible to fires and pests than the forests that they have replaced.…”

“…These Chinese fir monoculture plantations are carbon sinks, but they are more susceptible to fires and pests than the forests that they have replaced. Furthermore, soil nutrient depletion and yield reduction become common problems after one or more rotations (Tian et al, 2011). Thus, silvicultural practices that recreate historic forest stand structures and thereby optimize the use of the soil, have been a focus of the sustainable management of Chinese fir plantations in recent years, particularly in terms of maintaining soil productivity and ecosystem sustainability.…”

“…Hook is an important coniferous, fast-growing species that has been widely planted over an area of approximately 12 million ha in southern China (FAO 2010), which comprises about one third of the country's total plantation area. In addition to the economic benefits (timber production), Chinese fir forests provide important ecological benefits, including carbon sequestration, soil erosion conservation, and groundwater reposition at regional and national scales (Tian et al 2011). Recently, the plantation area of Chinese fir has been enlarged due to an increased demand for timber.…”

“…Recently, the plantation area of Chinese fir has been enlarged due to an increased demand for timber. However, the yield and productivity of pure Chinese fir plantations are extremely low because of low photosynthetic efficiency, poor soil fertility, and nonscientific management practices (Wang et al 2010;Tian et al 2011;Zhang and Wang 2012). Continuous planting on the same site is an important reason for the decline in soil fertility and the decreases in wood volume and productivity (Ding and Cheng 1995;Zhang et al 2004;Tian et al 2011).…”

Abstract& Key message A high-density plantation inhibited growth and biomass accumulation of Cunninghamia lanceolata (Lamb.) Hook. saplings, as well as their photosynthesis. This inhibition was enhanced in a soil that had been previously planted with the same species. The main factors limiting photosynthesis and growth were leaf-level irradiance and nutrient availability, mainly of P and Mg. & Context The planting density and continuous planting greatly affect the photosynthesis and productivity of Chinese fir plantations. The effects of high density and of continuous plantations over several revolutions need be disentangled. & Aims In this study, the responses of C. lanceolata seedlings to a high planting density were tested. Two soils were compared: a soil from a secondary forest and one from a continuous Chinese fir plantation. The study focused on growth and the potential processes involved in deduced photosynthesis. & Methods C. lanceolata seedlings were planted in wooden boxes (100×100×50 cm) with high and low planting densities (16 vs 1 plant m −2 ) in two types of soil. & Results Under the high planting density, C. lanceolata showed less growth and biomass accumulation at the individual level and lower photosynthetic rate and instantaneous photosynthetic nutrient use efficiency (PNUE and PPUE) at the leaf level. These negative effects were larger in soils that have been continuously planted with Chinese fir. The low photosynthesis was related to low phosphorus and magnesium contents in the leaves, changes in the foliar N/P and chlorophyll a/b ratios, and the limitation of the mesophyll conductance. & Conclusions The study showed that a high planting density induced enhanced competition for nutrients (particularly for P and Mg) and that this competition is enhanced in soils from continuous plantations compared to soils from natural forests.

Takuo Nagaike,1 2012 Current Status and Perspectives of Mixed Tree Plantations: A Review of Productivity Studies. J Jpn For Soc 94: 196 202 This paper discusses the pros and cons, effects on productivity and their mechanisms, and other issues related to mixed tree plantations as an alternative to pure tree plantations. Mixed tree plantations provide a broad range of goods and ecosystem services via the diversity of species planted. This diversity provides various habitats and ecological niches and can improve productivity through reduced competition and facilitation. Issues involved in experimental mixed plantations include the spacing and distribution of species and trees. Most previous studies have focused on young plantations. Because management practices need to vary according to the objectives of a mixed tree plantation, many issues need to be resolved for the practical introduction of mixed tree plantations.
