“…(2011a) and Yan et al. (2018b). The reasons why the mulching can enhance soil water storage probably lie in the followings: Firstly, in the SM, the hydrophilic fiber inside corn straw can retain water while its wax coat can prevent the water from being evaporated (Zribi, Aragüés, Medina, & Faci, 2015).…”

“…However, some studies have found that inappropriate mulching amounts and methods can have negative effects (Zhang et al., 2015). The traditional full straw practice often leads to the significant decrease in soil temperature due to low thermal conductivity (Ali et al., 2018; Yan et al., 2018a), and delayed crop emergence, which in turn influence crop growth, and even decrease the yield of wheat ( Triticum aestivum L.) (Yan et al., 2018b), maize ( Zea mays L.) (Linden, Clapp, & Dowdy, 2000; Lu, Li, Sun, & Bu, 2015) and other thermophilic crops due to the shortage of accumulated temperature. Some studies have found that both positive and negative effects existed with the practice.…”

Straw mulching is widely used in agriculture to conserve soil water and improve crop productivity. The effects of straw strip mulching and film mulching on dryland soil water storage and temperature, potato (Solanum tuberosum L.) growth and yield, and water use efficiency (WUE) were examined from 2014 to 2015 in the rainfed semi-arid regions of China. Field experiments were conducted with four treatments: (a) alternating strips mulched with maize (Zea mays L.) straw and bare plots with no ridges (SM); (b) alternating large ridges and small furrows with only the ridges mulched with black polyethylene film (PMP); (c) alternating narrows and wide ridges both mulched by black polyethylene film (PMF), and (d) traditional bare land planting without mulching (CK). The results indicated that film mulching had positive effects on soil water storage at the early stage of potato growth, while the SM significantly improved soil water storage at the late growth stage. Soil water storage (0-2-m depth) was 11.3-35.4 mm greater with the SM than that with the other treatments, especially during the tuber bulking in summer drought period. Compared with the CK, the SM significantly decreased soil temperature by 0.8-1.4 • C, and increased potato yield by 10.5-34.2%, WUE by 8.9-29.8%, and commodity rate by 14.7-38.8%. Compared with the PMP and PMF, the SM increased potato yield by 4.6-12.9 and 3.4-9.3%, respectively. This might be contributed to increased soil moisture and lower soil temperature, which promoted potato growth, yield, and commodity rates.Abbreviations: CK, traditional bare land planting without mulching; ET, evapotranspiration; PMF, narrow and wide ridges mulched by black polyethylene film; PMP, large ridges and small furrows only ridges mulched with black polyethylene film; SM, straw strip mulching; SWS, soil water storage; WUE, water use efficiency.

“…This condition resulted in the consequence that the root traits (root weight and root surface area) showed no significant differences between the irrigation and drought treatments. At maturity, roots grew more exuberantly in the drought treatment than the irrigation treatment, especially at the surface from 0-40 cm depth, which indicated that roots might overgrow to absorb more water from the soil to overcompensate for slight water stress conditions 36 . However, the production from root overgrowth did not counteract the carbohydrates consumed, which eventually led to a significant decrease in the yield in the drought treatment compared to the irrigation treatment 32 .…”

eight cultivars of winter wheat (Triticum aestivum L.) adapted to dryland conditions that have been historically planted in Shaanxi Province, China, were grown in plots with irrigation and drought treatments during the growing seasons of 2010-2012 to characterize the changes in root system traits and water use efficiency during the replacement of cultivars. The results showed that the overall root size of dryland wheat cultivars in Shaanxi Province changed with the planting decade. Modern cultivars developed after the 2000s had larger root surface areas than older cultivars under the drought treatment, especially at soil depths of 0-40 cm. However, the total water consumption throughout the stages showed no obvious changes among cultivars. The yield significantly increased with the planting decade, and the water use efficiency showed an average increase of 47.07% from the earliest to the most recent studied cultivar. Water stress promoted larger root sizes than those found in the irrigation treatment, especially at maturity. A trend toward a lower stress susceptibility index was observed over the decades, indicating that the sizes of modern cultivar roots increased less in the drought treatment than in the irrigation treatment. Both the roots and yields of the landrace cultivar from the 1940s showed low sensitivity to drought and better adjustment between the different water conditions. The study revealed that (1) modern wheat cultivars in Shaanxi Province possess higher water use efficiencies and decreased drought resilience and (2) the selection of ideal root traits should consider stable yields under different water conditions.Since Aamodt and Johnston (1936) promoted the importance of root growth for wheat yield (Triticum aestivum L.) 1 , the relationship between root traits and the yield potential of wheat has been the emphasis of research by agronomists and ecologists 2,3 . Early studies suggested that larger and deeper root systems were beneficial for greater water absorption 4,5 . However, studies in recent years have indicated that appropriate root sizes and better root physiological function could promote nutrient absorption and lodging resistance in wheat 6 , which contribute to high yield production 7,8 , while a root system that is too large results in root redundancy and causes an imbalance in the distribution of dry matter.There is continuous debate regarding the value of root size in dryland crops due to the diversities of environments, planting seasons and precipitation during growing seasons. It is generally considered that crops that mainly depend on presowing precipitation storage in the soil should reduce water use during the vegetative stage, as lower root growth rates in earlier stages are favorable for water use in the later stages of reproductive growth 9,10 . Conversely, larger root systems would be more beneficial for water absorption and utilization in areas with more precipitation 11,12 . A study by Nakhforoosh et al. (2014) proved that more roots near the surface soil are conducive t...

“…The soil and water loss mainly occurs on the sloping farmland. Currently, the soil erosion area is expanding, and the soil layer thickness is becoming thinner [2]. The topsoil thickness declined from 50-80 cm in the 1950s to 20-40 cm at present with 3-10 mm of soil loss per year [3].…”

“…Straw mulching has a good effect on soil and water conservation on gentle hillslopes in the Mollisol region of Northeast China [23]. However, the traditional full straw mulching practice often leads to a significant decrease in soil temperature [2], makes tillage difficult, and leads to unfavorable root penetration [18]. Straw mulching strips in the furrow improve water-use efficiency and yield [24].…”

Ridge tillage and straw returning are tillage practices widely used in the Chinese Mollisol region. However, the effects of ridge tillage combined with straw returning on runoff and soil loss control are still unclear. The objective of this study was to compare the effects of ridge tillage practices (contour ridge (CR)) and longitudinal ridge (LR), straw returning practices (straw on the furrow surface (SS)) and straw below the furrow (SB)), and their interactions on the runoff and soil loss by using simulated rainfall experiment. Two rainfall intensities (45 and 60 mm h−1) were applied to six combinations of ridge tillage and straw returning (contour ridge treatment, contour ridge with straw on the furrow surface treatment, contour ridge with straw below the furrow treatment, longitudinal ridge treatment, longitudinal ridge with straw on the furrow surface treatment, and longitudinal ridge with straw below the furrow treatment) on a 5° slope. The results showed that the phenomenon of ridge failure was common in the treatments with contour ridge. The average runoff rate and soil loss rate after ridge failure for treatments with contour ridge were separated 2.8 and 3.5 times greater than those of before failure at 60 mm h−1. However, the corresponding values were only 68.6% and 43.3% of the average value of longitudinal ridge treatment and longitudinal ridge with straw below the furrow treatment at 60 mm h−1. The water storage capacities of treatments with contour ridge remained constant when the rainfall intensity varied. The water storage capacities of contour ridge with straw on and below the furrow treatments were separate 3.0 and 1.0 mm less than that of contour ridge. However, longitudinal ridge with straw on the furrow surface treatment increased the runoff rate by 7.4% but reduced the soil loss rate by 72.6% when compared with longitudinal ridge treatment and longitudinal ridge with straw below the furrow treatment under the two rainfall intensities. Longitudinal with straw on the furrow surface treatment was more conducive to the stability of ridges, and there was no significant difference in total soil loss between longitudinal ridge with straw on the furrow surface treatment and treatments with contour ridge. This study was based on simulated rainfall conditions, and its adaptability under long-term positioning monitor in the field should be added in future.
