“…This resulted in increased soil available water storage in the potato sowing stage in the 0‐ to 40‐cm profile by 12.1 and 18.0 mm in 2016 compared with SS and TT, respectively, and correspondingly by 8.9 and 16.7 mm in 2017. This indicated that VRT increased the soil water supply ability (Zhang et al., 2020). Additionally, potato water uptake in VRT increased significantly, with periodical ET from budding to harvesting stage increasing by 44.2 and 34.7 mm in the drought year of 2016, compared with SS and TT, respectively.…”

“…The improved soil water characteristics are beneficial for soil water utilization (Araya et al., 2012; Lal & Shukla, 2004; Ma et al., 2015; Mohanty et al., 2007; Zhang et al., 2020). The improved soil water utilization has two components: the increment of crop water uptake ability, which depends on root development and activity (Bian et al., 2016; Cai et al., 2014; Guan et al., 2014), and the increment of soil water supply ability, which depends on soil water characteristics, especially soil available water storage (Li et al., 2013; Ma et al., 2015).…”

“…The experiment was a randomized block design with three replicates. The dimension of the experimental plot was 20 by 12 m. The ridge with mini‐ditch and whole field plastic mulching planting method (Figure 1) was used to cultivate potato; the width of the ridge bottom was around 60 cm, and height was 15 cm (Zhang et al., 2020). The width and depth of ditch on the ridge was 8–10 and 3–5 cm, respectively, and a pore was made in plastic film every 50 cm in the micro‐ditch to collect rainwater.…”

“…Vertical rotary sub‐soiling tillage (VRT) combined the advantage of rotary tillage and sub‐soiling (Li et al., 2013; Zhai et al., 2017), can better decrease soil bulk density and loosen the soil (Zhai et al., 2017; Zhang et al., 2020), and has potential to increase crop yield on top of plastic film mulching. The VRT machine, which includes two vertical spiral drills, can smash the soil vertically with a maximum tillage depth of 0.5 m. The decreased soil bulk density always results in increased pore space and the amount of water held at the saturation point (Jabro et al., 2015; Lampurlanés & Cantero‐Martíne, 2003; Mu et al., 2016; Yang et al., 2018; Zhang et al., 2020). These change in the soil physical properties make it easier for air and water to reach the roots of crop (Govaerts et al., 2006; Mûnoz‐Romero, Benítez‐Vega, López‐Bellido, Fontán, & López‐Bellido, 2010; Plaza‐Bonilla, Álvaro‐Fuentes, Hansen, Lampurlanés, & Cantero‐Martínez, 2014; Sun et al., 2017).…”

Vertical rotary sub‐soiling (VRT) has potential to increase potato (Solanum tuberosum L.) yields in semiarid rainfed area. However, despite the importance of this food crop, little research had been done on this topic. We describe results from a field experiment carried out during 2016–2017 in a semiarid area (104°36′E, 35°35′N), where potato crop was grown in a field with three tillage treatments: (a) vertical rotary sub‐soiling to a depth of 40 cm (VRT), (b) sub‐soiling to a depth of 40 cm (SS), and (c) traditional rotary tillage to a depth of 15 cm (TT as control). The results showed that the VRT decreased soil bulk density by 0.8–22.2 and 13.3–25.3% compared with SS and TT, respectively, leading to increased porosity (by 12.5–14.8 and 12.3–23.7%) and saturation water content (by 23.7–33.2 and 25.6–59.0%), together with reduced water content at wilting point (by 12.5–23.4 and 11.4–23.4%). This was equivalent to 23.7–33.2 and 25.2–59.0% increase in soil maximum available water (SMAW) of the soil profile down to 40‐cm depth compared with SS and TT, respectively. The increased SMAW resulted in increased tuber yield by 156.8 and 47.8%, corresponding increases in water use efficiency by 92.3 and 19.2% in 2016 compared with SS and TT, respectively. The similar results were observed in 2017. Our results demonstrate that VRT was an effective technology to further increase water use efficiency and crop yield on top of plastic film mulching in semiarid rainfed area.

“…The relative variability of precipitation is 24%, and the mean annual temperature is 6.2 °C. The average number of annual sunshine hours is 2500 h. The soil is a light loam of loess origin which belongs to litho logical soil, with organic matter content below 5%, and no salinity or alkalinity problems (Zhang et al., 2020). The soil water content (w/w) at field capacity is 23% and the wilting point is 7.2%.…”

Continuous maize cropping dries soils, while continuous potato cropping results in a soil moisture surplus, but decreases land productivity. To determine whether soil water balance and economic returns could be manipulated through maize‐potato rotation. The effects of 1) continuous maize cropping (M), 2) continuous potato cropping (P) and 3) maize‐potato rotation (R) on the variation in soil water content, water consumption, biomass and yield, economic benefits, and water economic yield were investigated. The depth of soil water consumption reached the maximum in 2016 (a dry year), at 260 cm, 200 cm, and 200 cm in M, P, and R, respectively. Compared with soil water storage in the 0–280 cm before planting in 2013, those after six years of cultivation were decreased by 186.31 mm in M, increased by 42.20 mm in P, and increased by 11.29 mm in R. R increased the post‐flowering/total depletion% by 16.81–44.65%, the post‐flowering/total biomass percentage by 10.83–24.83%, and water use efficiency of grain/tubers by 15.52–23.39% in 2016–2018, compared with M. Compared with M, R and P increased the total benefit by 55.44% and 41.62%, decreased ET by 10.69% and 17.93%, and increased EWUE by 74.02% and 72.52%, respectively. However, tuber yield and the water use efficiency of tubers in P decreased by 31.19% and 16.78%, respectively, from 2014–2017. Treatment R maintained the soil water balance, alleviated the over‐consumption of deep soil water caused by continuous maize cropping, and reduced the decline in soil productivity caused by continuous potato cropping.

Numerical simulation and experiment of the emergence of young potato sprouts through soil‐covered plastic mulching

et al. 2023

In this paper, the effect of covering the plastic film mulch with soil of different thicknesses, on the resistance of potato young stems to break through the plastic film was simulated using the explicit dynamic analysis software LS‐DYNA. The constitutive models of young potato stems, plastic film, and covering soil, specific to potato cultivation on the Loess Plateau of Northwest China, were established. The influence of the covering soil thickness on the resistance to breaking by the potato sprout was analyzed and the film breaking time and sprout resistance to growth were then compared. The simulation results reveal that, to minimize both film breaking time and resistance to sprout growth, a thickness of about 40 mm of the film‐covering soil can be considered a good choice in potato cultivation using plastic‐film mulching technology. The results were confirmed experimentally by the authors and matched previous experimental research reported in the literature.
