A significant warming effect of plastic film mulching with ridges and furrows occurred during the early growth stages of faba bean when canopies were small and solar radiation could penetrate the canopy to warm the topsoil beneath the film, as reported by Zhang et al [1] and Wang et al [13].…”

“…This technique has been instrumental in areas where irrigation is unavailable and spring temperatures are low [11,12], significantly reducing harvest time and nearly doubling grain yield [13]. Different mulching and planting practices can influence soil water retention, temperature stability, and resource use, affecting crop yield in diverse climatic zones [1,14]. The ridge-furrow with plastic film mulching technique, using ridges for rainwater harvesting and furrows for planting, efficiently increases soil temperature and facilitates rainfall infiltration, enhancing soil water availability and grain yield in arid and semi-arid regions [6,15].…”

Plastic film mulching is widely used in water and temperature-limited regions to enhance crop yields. Phosphorus (P) fertilization can address deficiencies in soil P availability. In this four-year field experiment conducted in an alpine agricultural area, we explored the effects of nitrogen (N) and P supply imbalance on faba bean cultivation, particularly examining intensified N competition between soil microbes and plants. The randomized block design comprised three film mulching treatments—no film mulching with flat planting (NMF), double ridges and furrows mulched with one plastic film (DRM), and three ridges and furrows mulched with one plastic film (TRM)—and three P levels—P0 (0 kg P ha−1), P1 (9.10 kg P ha−1), and P2 (18.2 kg P ha−1). The results indicated that NMF enhanced soil available N and microbial biomass N (MBN) during early growth stages, consequently improving faba bean yield, nodule weight, total N, and microbial biomass carbon (MBC) compared to DRM and TRM. DRM and TRM exhibited higher soil available N and MBN during later growth stages and higher soil temperature and water content, soil water storage (SWS), soil organic C (SOC), and soil C/N ratio than NMF. In NMF and DRM, P fertilization increased grain yield, nodule weight, SOC, total N, soil C/N ratio, soil available N, and MBC but decreased MBN during early growth stages, and decreased soil water content and SWS. TRM exhibited the opposite trend. P fertilization increased soil total P and available P. Overall, NMF combined with P fertilization (~18.2 kg P ha−1) significantly improved faba bean yield. However, it may also accelerate SOC decomposition, highlighting the need to consider N fertilizer application in this alpine agricultural region.

“…The ridge and furrow patterns provided better soil water and heat resources during the early growth stages, possibly because the ridge and furrow pattern simultaneously inhibited water evaporation and heat losses (Ren et al, 2008;. Moreover, the warming effect of R 2 F 2 was signi cantly better than that of R 3 F 2 as the result of the proper ridge to furrow ratio to promote water-temperature regulation (Luo et al, 2021;Yu et al, 2018).…”

Ridge and furrow planting system is widely used for yield-increasing in Northwest area of China. However, the effect of optimized ridge and furrow configuration (planting both on ridges and in furrows) to soil hydrothermal environment, maize canopy structure and grain yield are still not clear. Therefore, a 2-year (2015—2016) field experiment was conducted to investigate the regulatory effects of different planting systems [conventional flat planting without ridge (CK), ridge-furrow planting system with two row plants in both ridge and furrow (R2F2), and with three rows in a ridge and two rows in a furrow (R3F2)] on maize growth, grain yield and resource utilization. The results showed that soil hydrothermal environment and canopy structure were improved under the optimized ridge and furrow configuration, but not caused excessive water consumption. Compared with CK, the ridge and furrow configuration showed a greater advantage in virtue of coordinating water and temperature allocation, which increased LAI, photosynthetic capacity per plant and dry matter accumulation for plants in furrows. In addition, ridge and furrow systems represented a higher canopy light transmission rate of bottom layers, which contribute to more light interception capacity for plants. In comparison with CK, grain yield of R2F2 and R3F2 significantly improved by 20.5% and 12.4%, water use efficiency by 26.2% and 20.1%, radiation use efficiency by 28.2% and 17.8%, respectively. Overall, the optimized ridge and furrow configuration (R2F2) brought an improvement of soil hydrothermal environment, optimize canopy structure, and ultimately obtained an increase of grain yield.
