“…Plant height is a function of the number of nodes and the length of each internode, both of which are strongly influenced by greenhouse temperatures [35], and the overgrowth of plants at high temperatures occurs [36]. Micro-spray changes the air temperature (T a ) during the day, thus affecting internode spacing.…”

Drought and heat stresses are severe threats to crop production and food security in arid and semi-arid regions of the globe, especially during the summer. This study investigates the effects of micro-spray on micro-climatic and physiological characteristics of cucumber and tomato plants for four growing seasons (two growing seasons each (cucumber: 2017 and 2018 and tomato: 2021 and 2022)). The experiment was conducted in a Venlo-type greenhouse where plants were irrigated with a combined micro-spray and drip irrigation (MSDI) system (1 min for tomato (seven times a day) and 2 mins (four times a day) for cucumber) and drip irrigation (DI). Both plants’ growth and physiological parameters were recorded at the end of the experiment. Moreover, the experimental results showed that plant height and stem diameter increased under MSDI in all seasons. In addition, a micro-spray duration of 2 min decreased the average daily air temperature (Ta) and leaf temperature (T1) by 0.8 °C and 4.9 °C, respectively, and increased the average daily relative humidity (RH) by 4.3%. However, a micro-spray duration of 1 min reduced the average daily Ta and T1 by 0.76 °C and 4.6 °C, respectively, but the increase in RH (2.7%) was much lower than that in the single micro-spray duration of 2 min. In addition, the net leaf photosynthetic rate (Pn), the effective quantum yield of PSII (ΦPSII), and the stomatal conductance (Gs) of both plants increased under MSDI compared with DI. A K-means analysis showed that MSDI could eliminate the adverse effects of sunlight stress on cucumbers and tomatoes. MSDI increased the yield of cucumber and tomato plants by 18.9% and 40.4%, respectively. The fruit weight of cucumber (2017) and tomato (2021) under MSDI did not increase significantly compared to DI, which indicates that MSDI mitigated heat stress, prevented flowers from being burned, and increased the number of fruits. The results also suggested that the total soluble solids in the cucumbers and tomatoes showed no significant differences (p > 0.05) between the two treatments in four seasons. In conclusion, the MSDI system can be an appropriate strategy for the irrigation needs and climate control of plants grown in greenhouses during the hot season.

The increasing severity of global climate change has led to more frequent extreme high‐temperature events, significantly damaging rice yield and quality, thus posing a threat to global food security. Research indicates that plant‐microbe interactions can enhance plant growth and overall health under adverse conditions. Therefore, this review aims to explore strategies to improve rice heat tolerance through thermophilic microorganism mediation. This paper systematically summarises the effects of heat stress on both the aboveground and underground parts of rice during its growth stages, identifies the molecular mechanisms by which rice responds to heat stress, and explores the potential roles of microorganisms. Additionally, we review existing studies on microorganisms that alleviate plant heat stress and their mechanisms of action. Through case studies, we explore how microorganisms enhance rice survival in high‐temperature environments by regulating its growth and development, along with their potential applications in sustainable agriculture. In the future, environmentally friendly and efficient microbial inoculants and biofertilizers are expected to be developed based on microbe‐mediated plant heat tolerance mechanisms, which will help mitigate the heat stress challenges crops face under global climate change.
