“…Although plastic film mulch would greatly reduce soil evaporation, it also increased deep drainage to a certain extent, as the upward movement of water was hindered under plastic film mulch (Figure 7) and there was increased drainage due to free drainage at the lower boundary. Our conclusions on infiltration and drainage are inconsistent with the conclusions made under similar conditions in [26]. This is mainly due to the different simulation area settings (the simulation depth in this article was 0-100 cm, while that presented in the literature was 250 cm) and the two-times higher rainfall as the model input item in this article due to the ridge and furrow structure.…”

The ridge–furrow mulching system with plastic film (RFMS) has been widely used in semi-arid areas in order to improve soil water and heat conditions, crop yields and water use efficiency. It is of practical significance to study the effect of mulching and ridge types on soil water and heat in order to optimize mulching measures and improve the effectiveness of the ridge and furrow system. To clarify the combined effect of soil water and heat beneath the system and the influence of ridge morphology on it, field experiments were conducted with three treatments, including conventional planting in bare land (CK), a ridge–furrow (wide ridge with 70 cm width and 10 cm height, narrow ridge with 40 cm width and 15 cm height) mulching system with complete plastic film (RFWN) and a ridge–furrow (equal ridge with 55 cm width and 15 cm height) mulching system with complete plastic film (RFE). An insufficient irrigation system was adopted and the two-dimensional numerical software HYDRUS-2D was used to simulate the soil water and heat flow under the experimental conditions. The model was calibrated and verified according to test data for the period of 2018 to 2019, which showed good agreement between the simulated and measured values. The simulation results revealed that the ground temperatures of RFWN and RFE were much higher than that of CK, and the average value of 0–25 cm during the growth period could increase by 2.29–4.61%. Compared with CK, RFWN and RFE reduced soil evaporation (84.71–93.73%) and field evapotranspiration (12.02–21.75%), while they increased root water uptake (25.87–40.98%) and T/ET (48.85–80.15%). Plastic film mulching and ridge morphologies affected the infiltration range and the direction of soil water movement, increased soil moisture when there was no rainfall or irrigation and reduced soil water and heat fluctuations, which was more conducive to crop growth, especially under the RFWN system. The simulation method proposed in this paper is an effective technique for calculating the soil water and heat dynamics under different ridge and furrow sections under the condition of film mulching, and it can be used for the optimal management of soil water and heat in this area.

“…The difference of the results is due to less influence of indoor control experiment and more influence of in situ experiment. Considering that the in situ experiment is closer to the actual production active, the ridge width can be determined from the perspective of nutrient loss and crop yield (Wang et al, 2018;Liu et al, 2020). In this study, the runoff depth under CR tillage increased with the increase of ridge width.…”

Water and soil losses from sloping farmlands potentially contribute to water eutrophication and land degradation. However, few studies explored the combined effects of ridge direction and ridge width on surface runoff and soil losses of sloping farmlands. Twenty-seven experimental plots (8 m long and 4 m wide) with nine treatments (three ridge direction: cross ridge, longitudinal ridge, and oblique ridge; and three ridge width: 40, 60, and 80 cm) were adopted under natural rainfall conditions for two years in the Luanhe River Basin of China. Results indicated that ridge direction had significant effects on runoff and sediment yield (p < 0.05). The ridge width had no significant effect on runoff and sediment yield. No significant interaction effect was found between ridge direction and width on runoff and sediment yield of the sloping farmland based on statistical analyses. Compared with cross-ridge (CR) tillage and oblique-ridge (OR) tillage, longitudinal-ridge (LR) tillage significantly decreased runoff by 78.9% and 64.9% and soil losses by 88.2 and 83.5%, respectively (p < 0.05). The effects of ridge directions on runoff and sediment yield were related to rainfall grade. When the rainfall grade reached rainstorm, the runoff yield under CR, LR, and SR had significant differences (p < 0.05). The runoff under LR and OR treatment was 5.16 and 3.3 times, respectively, of that under CR. When the rainfall level was heavy rain or rainstorm, the sediment yield under LR was significantly greater than that under CR. The sediment yield was 13.45 times of that under CR. Cross-ridge tillage with a ridge width of 40 cm is an optimally effective measure of soil and water conservation on sloping farmland in arid and semiarid regions of China.

BACKGROUND Improving irrigation water productivity is vital for sustaining high maize yield in Hetao irrigated area of northwest China. Whether ridge cropping and furrow irrigation systems (planting both on ridges and in furrows) fulfill water‐saving and maize yield‐increasing is unclear. A 2‐year trial was conducted to reveal the influence of irrigation with three levels (270, 225, 180 mm, represented as I270, I225, I180, respectively) under two planting systems [traditional flat planting system (TFI) and ridge cropping and furrow irrigation system (RFI)] on maize growth, grain yield, water use efficiency (WUE) and irrigation water use efficiency (IUE). RESULTS RFI system increased soil water storage in 0–100 cm layer (P < 0.05), but did not cause excess water consumption, compared to TFI system. Logistic equation simulation showed that RFI system advanced the time of maximum dry matter growth rate (Tmax, 2.6–4.9 days) and prolonged the duration of dry matter accumulation (Td, 3.2–4.7 days), ultimately obtained a 4.2–9.5% improvement of dry matter. Compared with TFI system, RFI system increased WUE by 8.0–21.2%, IUE by 8.3–20.5% and grain yield increased by 9.4–21.4%. RFI225 satisfied water‐saving by 16.6% and yield‐increasing by 3.6–14.7%. CONCLUSION Ridge cropping and furrow irrigation systems brought an improvement of soil water storage and dry matter accumulation and kernel per spike, and ultimately obtained an increase of grain yield and water productivity. © 2022 Society of Chemical Industry.
