“…The temporal change in soil temperature is closely related to the growth period of cotton, and PFM can change the latent heat flux, such as cotton population water evaporation and soil water transpiration ( Jiang et al, 2022 ; Li et al, 2021 ), and then increase thermal radiation capture and topsoil temperature, especially in the early and middle stages of cotton growth ( Zong et al, 2020 ; Ghosh et al, 2006 ). In this study, before the initial flowering stage (July 1), especially before the first irrigation (June 20), the temperature of the 0–50 cm soil layer in the cotton field covered with plastic film was higher by approximately 2−4 °C than that in the uncovered cotton field.…”

Plastic film mulching (PFM) affects the spatiotemporal distribution of soil moisture and temperature, which in turn affects cotton growth and the spatiotemporal distribution of canopy photosynthetically active radiation (PAR). Due to the spatial heterogeneity of soil moisture, temperature and limited monitoring methods, the issues such as relatively few sampling points and long sampling intervals in most existing studies prevent the accurate quantification of spatiotemporal changes in moisture and temperature along soil profile. To investigate the effects of PFM on spatiotemporal changes in soil moisture, temperature, and canopy PAR in cotton fields, two field trials of plastic film-mulched (M) and nonmulched (NM) cultivations were performed in 2018 and 2019. The grid method was used for the soil information continuous monitoring and multiple-time fixed-site canopy PAR monitoring during the duration of cotton growth. Two-year field trial data showed that, M cultivation increased soil moisture by approximately 13.6%–25% and increased temperature by 2–4 °C in the 0–50 cm soil layer before the first irrigation (June 20) and by 1–2 °C in the 70–110 cm soil layer, compared with NM cultivation. In addition, the temperature difference between the two treatments gradually decreased with the increase in irrigation and air temperature. The M treatment reached the peak PAR interception rate 10 days earlier than the NM treatment. In 2018 and 2019, the PAR peak value under the M treatment was 4.62% and 1.8% higher than that under the NM treatment, respectively, but the PAR interception rate was decreased rapidly in the late growth stage. Overall, PFM had an effect on soil moisture retention during the whole growth period and greatly increased the soil temperature before budding stage, thus promoted the early growth of cotton. Considering this, we suggest that the irrigation quota and frequency could be appropriately decreased in the case of plastic film mulching cultivation. For nonmulching cultivation, the irrigation quota and frequency should be increased, and it is necessary to take measures to improve the soil temperature before middle July.

“…Climate warming would increase evaporation rates and atmospheric humidity (Song et al., 2022). Higher atmospheric humidity strengthens the greenhouse effect of water vapor, contributing to further warming (Jiang et al., 2023; Sherwood et al., 2018). Moreover, General Circulation Models (GCMs) in CMIP5 and observational data suggest that the warming climate will alter convective precipitation patterns, resulting in a phenomenon known as “wet‐get‐wetter” and “dry‐get‐drier” (Dittus et al., 2016; Donat et al., 2016; Du et al., 2022; IPCC et al., 2021).…”

“…Generally, higher soil moisture can contribute to temperature reduction due to the energy consumption involved in leaf/soil evaporation processes (Xu et al., 2004). However, it is essential to note the influence of soil moisture on climate warming varies depending on different background temperature thresholds (Jiang et al., 2023). These interactive climate changes are expected to have a significant impact on crop yield and soil GHG emissions, particularly in regions with stronger temperature‐moisture couplings (Griffis et al., 2017; Gupta et al., 2021; IPCC et al., 2021; Lesk et al., 2021; Tian, Lu, et al., 2016; Tian, Ren, et al., 2016; Tian et al., 2020).…”

Many agricultural regions in China are likely to become appreciably wetter or drier as the global climate warming increases. However, the impact of these climate change patterns on the intensity of soil greenhouse gas (GHG) emissions (GHGI, GHG emissions per unit of crop yield) has not yet been rigorously assessed. By integrating an improved agricultural ecosystem model and a meta‐analysis of multiple field studies, we found that climate change is expected to cause a 20.0% crop yield loss, while stimulating soil GHG emissions by 12.2% between 2061 and 2090 in China's agricultural regions. A wetter‐warmer (WW) climate would adversely impact crop yield on an equal basis and lead to a 1.8‐fold‐ increase in GHG emissions relative to those in a drier‐warmer (DW) climate. Without water limitation/excess, extreme heat (an increase of more than 1.5°C in average temperature) during the growing season would amplify 15.7% more yield while simultaneously elevating GHG emissions by 42.5% compared to an increase of below 1.5°C. However, when coupled with extreme drought, it would aggravate crop yield loss by 61.8% without reducing the corresponding GHG emissions. Furthermore, the emission intensity in an extreme WW climate would increase by 22.6% compared to an extreme DW climate. Under this intense WW climate, the use of nitrogen fertilizer would lead to a 37.9% increase in soil GHG emissions without necessarily gaining a corresponding yield advantage compared to a DW climate. These findings suggest that the threat of a wetter‐warmer world to efforts to reduce GHG emissions intensity may be as great as or even greater than that of a drier‐warmer world.
