“…Liao et al. (2022) reported that plastic mulching had improved soil moisture and thus affected crop growth, as well improved leaf chlorophyll content and increased photosynthesis. Further, the overuse of irrigation could leach down the nitrate below the root zone, and thus create the insufficiency of N supply, and thereby slow down photosynthesis and reduced grain yield (Hu et al., 2008).…”

The infrequent rainfall caused drought prone condition particularly in semi‐arid regions of China, where most of the precipitation occurs in summer season. Thus, the summer rainwater conservation is very important for winter wheat (Triticum aestivum) production. Therefore a 2‐year field experiment was conducted on straw mulch along with N fertilizer to improve physiology, nitrogen use efficiency (NUE), wheat yield, and water use efficiency (WUE). Maize (Zea mays) was a rotated crop after wheat, and therefore maize straw mulch (S1, 0 kg ha−1; S2, 4500 kg ha−1; S3, 9000 kg ha−1) was in the main plots, and N fertilizer (N1, 0 kg ha−1; N2, 192 kg ha−1 (80%); N3, 240 kg ha−1 (100%)) was in the sub plots. The interaction of S3N3 and S3N2 produced 59.2% and 43.8% higher net photosynthesis and enhanced its characteristics at booting stage compared with that of S1N1. Higher SPAD values (49.1 and 41.0%) and leaf area (85.6 and 61.0%) measured with S3N3 and S3N2 treatments at booting stage compared with S1N1. Both S3N2 and S3N3 had increased wheat N‐uptake (91 and 103%, respectively) compared to S1N1. While S3N3 and S3N2 enhanced soil moisture conservation, NUE (19.7 and 22.8%), and WUE (47.2 and 47.2%) with the improvement in the growth yield of wheat compared to S1N1. Higher 7604 kg ha−1 of wheat grain yield was obtained from interaction of S3N2. Therefore, interaction of S3N2 is a viable approach for improving the winter wheat crop performance in term of NUE, WUE and wheat yield for semiarid areas in China.This article is protected by copyright.

“…Film mulching, or film mulching combined with irrigation, can greatly facilitate N utilization (Gu et al, 2021;Liao et al, 2022). Some research studies have suggested that high soil temperature under PI-limited root activity decreases N supply to the canopy and thus accelerates plant senescence (Yang et al, 2016).…”

IntroductionDrip irrigation is an efficient water-saving system used to improve crop production worldwide. However, we still lack a comprehensive understanding of maize plant senescence and its association with yield, soil water, and nitrogen (N) utilization under this system.MethodsA 3-year field experiment in the northeast plains of China was used to assess four drip irrigation systems: (1) drip irrigation under plastic film mulch (PI); (2) drip irrigation under biodegradable film mulch (BI); (3) drip irrigation incorporating straw returning (SI); and (4) drip irrigation with the tape buried at a shallow soil depth (OI), and furrow irrigation (FI) was used as the control. The plant senescence characteristic based on the dynamic process of green leaf area (GLA) and live root length density (LRLD) during the reproductive stage, and its correlation with leaf N components, water use efficiency (WUE), and N use efficiency (NUE) was investigated.ResultsPI followed by BI achieved the highest integral GLA and LRLD, grain filling rate, and leaf and root senescence rate after silking. Greater yield, WUE, and NUE were positively associated with higher N translocation efficiency of leaf protein responding for photosynthesis, respiration, and structure under PI and BI; whereas, no significant differences were found in yield, WUE, and NUE between PI and BI. SI effectively promoted LRLD in the deeper 20- to 100-cm soil layers, prolonged the GLA and LRLD persistent durations, and reduced the leaf and root senescence rates. The remobilization of non-protein storage N was stimulated by SI, FI, and OI, which made up for the relative inadequacy of leaf N.DiscussionInstead of persistent GLA and LRLD durations and high translocation efficiency of non-protein storage N, fast and large protein N translocation from leaves to grains under PI and BI was found to facilitate maize yield, WUE, and NUE in the sole cropping semi-arid region, and BI was recommend considering that it can reduce plastic pollution.
