“…Climate changes, particularly dramatic warming and severe drought events, have occurred around the world [1], most notably in northern China [2,3]. These changes exert a strong influence on forest dynamics and growth [4][5][6]. Therefore, to assess the impacts of future climate change on forest growth, it is crucial to study the climatic forcing of tree growth at annual and seasonal time scales.…”

Dryland montane forests are important agents for soil and water resource conservation. The growth of these forests under climate warming is strongly affected by local environmental factors. However, how environmental factors impact intra-annual stem growth dynamics across environmental gradients in these regions remains unclear. This work focused on assessing seasonal patterns of stem growth across different elevations and how environmental factors impact stem growth in the Qilian Mountains, northwestern China. The stem growth of 50 Qinghai spruce trees was monitored for two years across an elevation gradient from 2500 m to 3300 m above sea level (a.s.l.). We found that growth initiation occurred later as the elevation increased, and growth commenced when elevation-specific temperature thresholds were reached. However, growth cessation presented large elevational differences: cessation occurred much earlier at low elevations (2500 m and 2700 m a.s.l.). Exceptionally early growth cessation occurred predominantly at 2700 m a.s.l., which was correlated with seasonal drought/insufficient rainfall and low soil moisture occurring since mid-July 2015. Temperature and soil moisture were the key factors governing the daily rate of stem growth in the beginning, rapid growth, and end stages. Overall, due to effects of seasonal drought and low temperature on growth cessation and growth rate, the annual growth of Qinghai spruce was rather low at both low (2500–2700 m a.s.l.) and high (3100–3300 m a.s.l.) elevations; middle elevations (approximately 2900 m a.s.l.) might be the most favorable Qinghai spruce growth. Our results implied that tree growth will likely decline at low elevations and that the optimal elevation for Qinghai spruce growth in northwestern China is expected to shift upward under future climate warming.

“…This transplantation method avoids damage to the seedling roots, shortens the seedling recovery period, and promotes the formation of tillers. Regeneration is an essential and complex process in forest dynamics [26][27][28], and this rule also applies to rice. The new branches and leaves produced by tillering can increase the photosynthetic area of rice and improve photosynthetic efficiency, thus increasing rice yield.…”

Nursery trays are essential agricultural tools in rice production. Plastic nursery trays pose problems such as resource waste and environmental pollution. Biomass seedling trays are an effective way to achieve sustainable agricultural development. Previous research has been conducted on biomass seedling tray molding equipment and molding process, but the impact of raw material ratio on seedling tray molding quality and seedling growth is still unclear, and the ratio combination still needs further optimization. In this study, we used slurry concentration, pulp content, adhesive content, and the ratio of straw to cow manure as variables. We selected the bowl hole molding rate and the strong seedling index as evaluation indicators, and carried out biomass seedling tray forming experiments and seedling cultivation experiments. The response surface analysis method was used to optimize the raw material ratio of biomass seedling trays from the perspectives of forming effect and seedling quality. The results show that when the slurry concentration is 30%, the pulp content is 20%, the adhesive content is 530 g, and the mass ratio of straw to cow manure is 2:1; the bowl hole molding rate is 91.03%, and the strong seedling index is 0.22, indicating good molding effect and seedling growth. The verification test results indicate that the theoretical analysis results are accurate, and the model fitting is good. These research results provide a theoretical basis for the preparation of biomass seedling trays and technical support for achieving green development in agriculture.

“…Forest ecosystems play a central role in the global carbon cycle ( Teets et al., 2018 ; Ameray et al., 2021 ), climate regulation ( García-Valdés et al., 2020 ) and other ecological services ( Kumar et al., 2008 ). Global climate change may have important impacts on forest productivity, biomass and phenological periods ( Hof et al., 2021 ; Guo et al., 2022 ; Molina et al., 2022 ). Climate factors are important drivers of forest productivity, and future climate change may lead to a decline ( Sabatia and Burkhart, 2014 ; Debaly et al., 2022 ) or an increase ( Chen et al., 2020 ) in forest productivity.…”

Predicting the growth suitability of Larix principis-rupprechtii Mayr based on site index under different climatic scenarios

et al. 2023

Larix principis-rupprechtii Mayr (larch) is one of the main afforestation and timber production species used in North China. Climate change has led to a change in its suitable distribution and growth. However, the impact of climate change on its growth suitability is not clear. In this study, using forest resource inventory data and spatially continuous environmental factor data (temperature, precipitation, topography, and soil) in Hebei and Shanxi Provinces, China, the random forest model (RF) was used to simulate the larch site index (SI) and growth suitability under three shared socioeconomic pathways (SSPs: SSP1-2.6, SSP2-4.5, and SSP5-8.5) for the current and future (2021–2040, 2041–2060 and 2080–2100). The results revealed that (1) RF had excellent performance in predicting the regional SI (R2 = 0.73, MAE = 0.93 m, RMSE = 1.35 m); (2) the main factors affecting the productivity of larch were the mean temperature of the warmest quarter (BIO10), elevation (ELEV), mean diurnal range (BIO2), and annual precipitation (BIO12); and (3) larch currently had a higher SI in the Bashang areas and in the high-altitude mountains. The areas characterized as unsuitable, poorly suitable, moderately suitable, and highly suitable accounted for 15.45%, 42.12%, 31.94%, and 10.49% of the total area, respectively. (4) Future climate warming had an obvious inhibitory effect on the SI, and the effect strengthened with increasing radiation intensity and year. (5) The moderately suitable and highly suitable areas of larch growth showed a downward trend under future climate scenarios. By the end of this century, the suitable growth areas would decrease by 14.14% under SSP1-2.6, 15.17% under SSP2-4.5, and 19.35% under SSP5-8.5. The results revealed the impact of climate change on larch growth suitability, which can provide a scientific basis for larch forest management.
