“…Mulch increased pre-anthesis dry matter under tested conditions (Figure 1), in agreement with previous studies [31,32]. The reason is that mulch improves soil temperature [8,11] and reduces soil water loss [33,34], which benefits seedling emergence and tillering, and rapid growth after regreening [35]. The increment of pre-anthesis dry matter under mulch was more in WSC content and less in SDM, and subsequently, WSC translocation was greater relative to bare ground (Table 2, Figure 3).…”

“…Mulches including straw [5,6], sand or gravel [7], and plastic film [6,8,9] have been extensively tested to increase precipitation utilization efficiency. Plastic mulch reduces soil evaporation, increases soil temperature and root and shoot growth, and increases winter wheat yield and water use efficiency compared to bare ground in the Loess Plateau [10,11]. In contrast, plastic mulch, shortens the leaf life span, the duration of grain filling, and the yield of spring wheat when encountering severe drought and high soil temperature after anthesis [12,13].…”

Plastic film mulching often increases the yield of winter wheat in the Loess Plateau of China, but the physiological mechanisms are unclear, especially in response to the interaction between mulch and water supply. In this study, we investigated the interactive effects of initial soil water (dry, moderate, and wet), soil cover (plastic mulch, bare soil), and seasonal conditions on the dynamics of dry matter partitioning, water-soluble carbohydrates (WSC), and flag leaf senescence, and their relations with yield and its components. Plastic mulch increased dry matter accumulation at anthesis and maturity relative to bare soil, with no interaction with season or initial soil water. Allocation of dry matter to leaf, stem, and spike did not change with soil cover. Compared with bare soil, mulch increased WSC accumulation by 14% at anthesis and its translocation by 16%. Soil cover did not influence the senescence of flag leaf after anthesis as indicated by similar dynamics of the C:N ratio. Grain yield was higher under plastic mulch than bare soil in two out of three seasons, and was associated with a higher translocation amount of WSC and post-anthesis dry matter that linked grain weight, grain number, and harvest index.

“…It is worth noting that under the same test treatment, the precipitation in the growth period of crops in 2018 was higher than that in 2017, but the crop yield was lower, which may be due to the severe drought in the first quarter of 2018, affecting the growth of crops in the seedling period. Although there was more rain in the second quarter, it was not enough to completely compensate for the negative impact of the previous drought on crop growth [ 20 ].…”

Straw mulching farming is currently an effective dry farming technique for improving arid soil environments. Straw mulching technology can increase the infiltration capacity of soil water and improve crop yield and water use efficiency. In this study, the aim is to improve the soil water holding capacity, water retaining capacity, and comprehensive water use efficiency of crops in dry farmland. First, the response surface model is used to study and analyse the optimal parameters of straw returning and its mulching technology, and then, the crop yield, water consumption, and comprehensive water use efficiency of spring corn under different mulching conditions during 2017-2019 are studied. The test results show that the optimized parameters obtained by the response surface model are as follows: film thickness is 0.03 mm, straw returning amount is 4500 kg/hm2, straw particle size is 5 mm, and straw returning depth is 25 mm. At this time, the maximum soil water storage can reach 404.50 mm. The results of the straw mulching test show that under 4500 kg/hm2 mulching, the soil has more water storage, higher soil water content, and a simultaneous increase in water consumption, which is conducive to the efficient use of limited precipitation by crops. The field experiment for three years shows that 4500 kg/hm2 straw (wheat) mulching in the dry farming area of southern Ningxia can better store water and protect soil moisture, promote the virtuous cycle of farmland soil water, and show outstanding performance in improving corn yield and water use efficiency, which can be popularized and implemented in spring corn production in this area.

“…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.…”

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
