“…This result is similar to that of R. Li et al. (2021), who reported that straw mulching increased ET and its proportion in the jointing‐blooming stage of wheat. Additionally, our study showed that the ST + S treatment significantly decreased ET during the reproductive stage but increased ET during the vegetative stage of wheat; consequently, the total ET during the whole crop growing season had no significant difference among different tillage treatments.…”

“…In our study, ETw 1 was higher than ETw 2 during the wheat growth stage over the 3 years (Table 1), possibly due to the rainfall discrepancy between the vegetative and reproductive stages of wheat. This finding is similar to the results presented by R. Li et al (2021), who showed that ET in the vegetative stage (from sowing to blooming) was higher than that in the reproductive stage (from blooming to maturity) of winter wheat. D. Ding et al (2018) also discovered that the ET rate dramatically increased in the vegetative stage (from overwintering to regreening) of winter wheat and always had a peak value in the vegetative stage (jointing stage) of the crop.…”

Understanding the combination of conservation tillage and straw mulching on water utilization is important for developing water management strategies in arid and semiarid areas. Few studies have investigated the effects of different tillage treatments on precipitation efficiency in winter wheat (Triticum aestivum L.)‐summer maize (Zea mays L.) cropping systems. A 3‐year field experiment with five treatments, that is, conventional tillage (CT), no‐tillage, no‐tillage with straw mulching (NT + S), subsoiling tillage, and subsoiling tillage with straw mulching (ST + S), was conducted. The objective was to investigate how conservation tillage with straw mulching affected soil water storage (SWC), precipitation storage efficiency (PSE), water consumption, grain yield, water use efficiency (WUE), and precipitation use efficiency (PUE) in a winter wheat‐summer maize cropping system. The results indicated that the ST + S treatment increased SWC by 10.1% and 8.3% in 2014–2015 and 2015–2016, respectively. The average PSE over the 3 years under the ST + S treatment was significantly higher, by 9.1% and 6.6%, than that under the CT treatment during the respective wheat and maize seasons. Compared with CT, the average annual yield under the NT + S treatment and ST + S treatment increased by 8.5% and 14.4%, respectively. In the winter wheat‐summer maize system, the NT + S and ST + S treatments significantly increased the annual WUE and PUE. The annual average PUE under the ST + S treatment was significantly higher, by 14.1%, than that under CT over the 3 years. Therefore, the ST + S treatment was more beneficial than the other treatments for increasing yield, WUE and PUE in sandy loam soil on the North China Plain.

“…Covering the soil with the plastic film will promote the growth and development of annual and perennial crops and increase the yield. Film can effectively improve the field microclimate for crop growth, increase crop yield, and enable crops to develop well in soils with little water ( Lamont, 2005 ; R. Li R et al, 2021 ). Experiments have shown that the application of biodegradable film in the soil can promote the growth and development of crops such as pepper ( Mari et al, 2020 ), tomato ( Cirujeda et al, 2012 ; Abduwaiti et al, 2021 ), corn (N. Chen et al, 2021 ), and cotton (L. X.…”

“…Today, the most common film for soil is plastic film. Plastic film can effectively improve the field microclimate for crop growth, increase crop yield, and enable crops to develop well in soils with limited moisture ( Kader et al, 2017 ; Lamont, 2005 ; R. Li R et al, 2021 ). However, the residues of plastic film will seriously harm the ecological environment and have a series of adverse effects on the soil, such as reducing soil porosity, soil water content, and increasing soil bulk density (Y. L. Qi Y. L et al, 2020 ).…”

Based on the Web of Science Core Collection (WOSCC) database, the academic works published in the past 30 years on biodegradable films for soil were analyzed. In order to ensure the rigor of this experiment, this paper is based on the mathematical double matrix model VOS Viewer software and CiteSpace software. This work shows that publications of biodegradable films for soil are increasing year by year; polymer science is the hottest subject in the field of biodegradable films for soil; China and the United States are the countries with the most significant number of publications in this field, has an important position; Washington State University is the most published institution. This study further identifies and reveals the essential characteristics, research strength, knowledge structure, main research fields, and research hotspots in the late stage of the field of biodegradable films for soil and introduces the Activity Index (AI) and the Attractive Index (AAI), thereby assessing trends and performance in different countries. The paper also further illustrates the importance of biodegradable films by presenting field trials using biodegradable films on different plants. The research in the field of biodegradable films for soil is divided into four categories: “The research field of degradation,” “The effect of biodegradable film on soil,” “Performance and mechanism of the biodegradable film,” and “Effects of biodegradable film on crop growth and development.”. The study can be seen as a microcosm of the development of biodegradable films for soils, which will help researchers quickly identify their general patterns. Readers can better understand the changes and development trends in this field in the past 30 years and provide references for future research.

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