Owing to global warming, continuously increasing the grain yield of rainfed maize is challenging on Loess Plateau in China. Plastic film mulching has been extensively utilized dryland agriculture Plateau. However, higher topsoil temperatures under mulch caused rainfed-maize premature senescence and loss. Here, we aimed explore influence temperature driven by novel double patterns productivity based excellent moisture conservation function plastic film. A field experiment was conducted two different areas, namely Changwu, a typical semi-arid area, Yangling, dry semi-humid area. The followed randomized block design with three replications. Five flat-planting practices were examined 2021 2022: (1) bare land (CK), (2) transparent (PFM), (3) black (BFM), (4) PFM polyethylene net (PFM + BN), (5) whole stalks ST). Soil hydrothermal conditions, growth dynamics, yield, water use efficiency (WUE), economic returns quantified practices. Under treatments, lower than 1.7–2.0 °C at sites (p < 0.05), whereas BFM slightly that 0.6–0.7 Yangling > 0.05). average period for longer 8–11 days sites. Double treatments significantly improved leaf area index (LAI), chlorophyll relative content (SPAD), aboveground biomass compared CK during late stage.

Can dual mulching outperform single mulching in arid agriculture—Loess Plateau? A meta‐analysis based on crop yield and water use efficiency

Land Degradation and Development, Journal Year: 2024, Volume and Issue: 35(11), P. 3700 - 3713

Abstract Field mulching is an important technique for dryland crop cultivation in the Loess Plateau (LP) of China, which alleviates local agricultural water shortage. However, under different precipitation and temperature conditions, effects on moisture conservation yield enhancement are not consistent. A meta‐analysis was conducted to assess variations across various variables (mulching types, rainfall annual average temperature) based data from 203 peer‐reviewed publications, including 1466 991 use efficiency points. The results indicated that compared with no (CK), plastic (PM), straw (SM), dual (SPM) significantly increased both (WUE), SPM demonstrating most substantial improvement. Under conditions low (<7°C), PM improved WUE. Similarly, when temperatures were below 7°C ranged 400 600 mm, SM also enhanced Compared PM, does enhance WUE high‐temperature low‐precipitation (>12°C, ≤400 mm) low‐temperature high‐precipitation (≤7°C, >600 conditions. outperforms enhancing diverse hydrothermal Furthermore, we green development assessment using DPSIR model, after 20 years development, found potential greater than PM. Overall, only enhances but serves as effective replacement thereby boosting production agriculture. Its crucial role advancing regional has been validated by scientific research.
