“…Our results also showed that plastic film mulching treatments significantly increased the DM of winter wheat throughout the growth stage (Figure 4). This may be because plastic film mulching promotes nutritional growth (vegetative growth) and yield formation of winter wheat by maintaining the soil temperature and moisture content (Li et al., 2021), and moderately increasing the soil temperature also increases soil bioactivity and metabolism (Li et al., 2004; Subrahmaniyan et al., 2006). Previous researchers have also found that mulching promotes the accumulation of DM (Ali et al., 2019; Li et al., 2020; Luo et al., 2020).…”

“…Ding et al, 2019). In addition, mulching has been found to increase the leaf area index, DM, and net photosynthetic rate of winter wheat, thereby increasing the final spike number and yield (Ding et al, 2021;Fang et al, 2022;Gu et al, 2021;Li et al, 2021). Moreover, mulching improves the radiation utilization efficiency (RUE) and water use efficiency of winter wheat (Hu et al, 2020;Zhang et al, 2022), and other studies have shown that plastic film mulching can effectively inhibit the accumulation of surface soil salt, thereby promoting crop growth (Li et al, 2017;Liu et al, 2020) and more effectively tapping into the crop production potential in saline-alkali areas.…”

“…Film mulching can significantly increase the soil temperature during the tillering stage of winter wheat, reduce soil evaporation, and maintain surface water during the wheat growth stage (Yang et al., 2018a; Yang et al., 2018b), which reduces phosphate leaching and effectively promotes the emergence of wheat leaves and the development of tillering nodes (Dai et al., 2021; D. Ding et al., 2019). In addition, mulching has been found to increase the leaf area index, DM, and net photosynthetic rate of winter wheat, thereby increasing the final spike number and yield (Ding et al., 2021; Fang et al., 2022; Gu et al., 2021; Li et al., 2021).

Crop yields are seriously threatened in saline–alkali areas with shallow groundwater levels and high evaporation. Mulching can effectively alleviate salt stress on crops in drylands, but there is limited research on winter wheat (Triticum aestivum L.) mulching in coastal saline–alkali areas. To investigate the effect of plastic film mulching on the growth and yield of wheat in coastal saline–alkali soil, three field management measures were designed: bare ground (CK), plastic mulch (PM), and sub‐soil plastic film (PMF). Compared with CK, PM and PMF significantly increased wheat grain yield by 128.2%–313.2% and 187.8%–537.0%, respectively, over the two study stages. The movement of salt to the surface is inhibited after mulching; as a result, PMF and PM significantly decreased the electric conductivity in shallow soil (0–20 cm) by 31.1% and 23.8%, on average, compared to CK, resulting in a significant increase in dry matter accumulation (DM) for winter wheat throughout the growing season. Moreover, PMF increased the overall DM by increasing the DM for each plant (DMP), while PM achieved a similar effect to PMF by increasing the number of tillers. Compared with PM, PMF had a better inhibitory effect on shallow soil salinity, significantly increasing the effective number of spikes, effective tillering rate, DMP, and spike weight at harvest; promoting vegetative and reproductive growth of wheat fields; and ultimately increasing yield. PMF can be used to improve winter wheat production in coastal saline–alkali soils.This article is protected by copyright. All rights reserved

“…Mulching of various other crops, particularly for WUE, can reduce the adverse effects of DS on plant growth and development (Qin et al, 2015(Qin et al, , 2021. For example, in winter wheat under semi-arid conditions, straw strip mulching significantly reduced soil temperature relative to plastic film mulching and non-mulching, thus reducing evaporation and ultimately increasing water-holding capacity (Li, Chai, Chai et al, 2021). Soil K application improved WUE, leaf K content, leaf water potential, and gaseous exchange in eucalyptus (Eucalyptus urophylla S. T. Blake) (Santos et al, 2020).…”

Breeding crop plants with increased yield potential and improved tolerance to stressful environments is critical for global food security. Drought stress (DS) adversely affects agricultural productivity worldwide and is expected to rise in the coming years. Therefore, it is vital to understand the physiological, biochemical, molecular, and ecological mechanisms associated with DS. This review examines recent advances in plant responses to DS to expand our understanding of DS-associated mechanisms. Suboptimal water sources adversely affect crop growth and yields through physical impairments, physiological disturbances, biochemical modifications, and molecular adjustments. To control the devastating effect of DS in crop plants, it is important to understand its consequences, mechanisms, and the agronomic and genetic basis of DS for sustainable production. In addition to plant responses, we highlight several mitigation options such as omics approaches, transgenics breeding, genome editing, and biochemical to mechanical methods (foliar treatments, seed priming, and conventional agronomic practices). Further, we have

Many studies showed that afforestation increases carbon storage and it can have effects on physical, chemical and biological properties of soil. Afforestation can affect local and regional climate and these effects differ between tropical, temperate and boreal areas. Forests are also efficient in protecting soils against erosion and their flood mitigation functions or other benefits are described in different publications. In this study, the pattern of air temperatures (20 cm, 40 cm and 60 cm above the surface) was studied 10 years after the afforestation of agricultural land (warm, mild dry region of the Czech Republic) with a mixture of broadleaved tree species (Quercus robur L., Quercus rubra L. and Acer platanoides L.) or monospecific Pinus sylvestris L. stand. The aim of our study was to find out the pattern of air temperatures (20 cm, 40 cm and 60 cm above the surface) on two plots (one of the plots ‒ old beech trees, the other plot ‒ clearing) in a beech (Fagus sylvatica L.) forest in a mildly warm, mildly wet region of the Czech Republic. The afforestation of agriculturally used land led to air temperature cooling and to a reduction of the amplitude of maximum and minimum temperatures. The average air temperature (from April 2021 to the beginning of November 2021) decreased by 0.7–1.1 °C on the afforested plots compared with the agriculturally used plot. In the beech forest, the average temperature decreased on the plot with clearing compared with the old beech trees (from the middle of September 2021 to the middle of November 2021). Our results confirm the benefits of afforestation to climate change mitigation; buffering of extreme temperatures is important for the human thermal comfort.
