“…Prager yield criterion was added to the Mohr-Coulomb yield criterion because it describes the soil behavior more realistically and avoids the singularity of the Mohr-Coulomb yield criterion from affecting the convergence (Sun., 2014).…”

“…The parameters of plastic-film material were measured according to the standard GB/13022-91 test method for tensile properties of the plastic film and a constitutive model of plastic film materials was constructed, see Table 2 and Wang The compression failure of potato young stems can be roughly divided into the approximate elastic stage, yield stage, and deformation failure stage. It is difficult to measure the Poisson's ratio of potato stems because of their small size, high moisture content, and because they cannot reach the yield stage when unearthed (Sun, 2014). For the potato young stems, the same linear elastic material model MAT_ELASTIC has been adopted, with the numerical parameters as shown in Table 3 (Sun, 2014;Lai et al, 2018).…”

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.

“…The high solar radiation in this region can lead to high crop production. However, yields are often low and unstable due to the region's scarce rainfall and infertile soils [4]. Therefore, improving soil moisture and nutrient availability to match solar radiation resources is crucial for achieving greater and more stable grain yields.…”

“…The efficient storage of precipitation is an effective way to deal with the low availability of soil moisture [5]. Ridge-furrow plastic mulching (RFPM) is considered the most effective planting technology in rain-fed agricultural areas due to its ability to collect and store precipitation [4,6]. Previous studies have shown that the RFPM system facilitated precipitation infiltration, suppressed soil evaporation, increased daily radiation, and raised the soil temperature in the early stage of crop growth [7,8].…”

Ridge and furrow plastic mulch (RFPM) and nitrogen (N) application are effective strategies for improving crop productivity in China’s Loess Plain. However, it is not clear how the ridge–furrow ratio and nitrogen fertilizer type (NT) affect the use of water, nitrogen, heat, and radiation resources for the enhancement of rain-fed wheat production. Two nitrogen fertilizer types (traditional urea (TU) and controlled-release urea (CRU)) and four planting patterns (conventional flat planting (F) and the RFPM system of 20 cm ridges with 40 cm furrows (R2F4), 40 cm ridges with 40 cm furrows (R4F4), and 60 cm ridges with 40 cm furrows (R6F4)) were tested from September 2018 to June 2021 during the winter wheat growing season. It was found that the RFPM system can increase soil thermal time (TTsoil) from 41.0 to 152.1 °C d compared to the F. RFPM system thermal effect, which reduced the vegetative growth period and prolonged the reproductive growth period for 2 to 7 days, which promoted an increase in the leaf area index (LAI) and final dry matter (DM) accumulation. These significantly increased the grain yield (GY) in the RFPM system by 51.6–115.2% and enhanced the thermal time use efficiency (TUE) by 48–99.5%, water productivity (WP) by 37.4–76.3%, radiation use efficiency (RUE) by 16.3–34.4%, and partial factor productivity of nitrogen (PFPN) by 51.6–115.2% compared to F. Although a high ridge and furrow ratio in combination with CRU increased the GY and resource use efficiency, it also exacerbated the soil water depletion, especially in the soil layer between 40 and 140 cm. Overall, CRU combined with the 40 cm ridge and 40 cm furrow RFPM system maximized resource efficiency and increased wheat production on China’s Loess Plateau.

BACKGROUNDThe ridge‐furrow rainwater harvesting system (RFRH) is an advanced farmland management technology that plays a vital role in making full use of rainwater resources. However, it is not clear that RFRH affects crop yield and water use efficiency (WUE) by regulating soil water storage (SWS). Therefore, the present study conducted a meta‐analysis to make a large compilation of previous studies and indirectly quantify the impact of RFRH on crop yield and WUE by analysing the effect of RFRH on SWS.RESULTSThe results showed that RFRH improved crop yield and WUE by 26.71% and 25.86%, respectively, by increasing SWS by 3.93% compared to the traditional flat cultivation. RFRH had a significant effect on increasing crop yield and WUE and improving SWS. A low ridge‐furrow ratio and ridge‐furrow mulching were recommended to obtain positive effects on crop yield and WUE when potatoes are grown in areas with high precipitation (600–800 mm). Furthermore, when nitrogen fertilization is applied during the crop growth period, we also found that a medium nitrogen fertilizer rate is recommended to achieve a significant positive effect on crop yield and WUE. Importantly, a win‐win analysis showed the proportions of various groups in the target zone (zone I) to determine the appropriate strategy for RFRH of crops.CONCLUSIONThe present study provides a scientific reference for the future application of the RFRH. The study provides scientific recommendations on crop types, ridge‐furrow configurations, plastic mulching patterns and nitrogen fertilizer rate for future RFRH applications. © 2024 Society of Chemical Industry.
