“…In recent years, the research on exogenous antifreeze has gradually increased, and a variety of effective plant antifreeze agents have been successfully screened out, which are mainly divided into inorganic salts (calcium chloride), organic compounds (salicylic acid (Ma and Ma 2016 ), aminobutyric acid, naphthalene acetic acid), plant hormones (brassinolactone, abscisic acid, melatonin), and new plant antifreeze agents (chloranilide, malehydrazide, etc.) (Liu et al 2022a , b ). Studies have shown that potassium dihydrogen phosphate & brassinolide" is a cost-effective combination of antifreezing that can adjust the endogenous hormone balance of crops, enhance resistance, alleviate drug damage, help crops recover quickly, and significantly reduce freezing damage (Li et al 2021a , b ).…”

“…On the one hand, the cost is too high, which is difficult to bear in production (Li et al 2022 ), and, on the other hand, the effect of cold prevention is unstable from year to year, which has certain risks (Li et al 2013 ). In the severely cold areas of northern China, the existing liquid mulch is not sufficient to prevent root systems from freezing, and it cannot be popularized in a large area (Liu et al 2022a , b ).…”

In northwest China, where winter is extremely cold and the grapevine is vulnerable to freezing damage, the application of soil covering has promoted the vigorous development of the local grape and wine industries. However, in recent years, the negative effects of burying soil for cold protection on the environment have gradually emerged. In some viticultural regions, the phenomenon of "summer forest, winter desert" has appeared. Therefore, it is urgent for the Chinese grape industry to find a better solution to overwinter safely and environmentally friendly. This review summarizes the advantages and disadvantages of widely used solutions to overwinter such as covering vines with soil, breeding of cold-resistant grapes, cold-resistant cultivation model, physical and chemical covering materials, and protected grape facilities were reviewed. Future overwintering measures were proposed which avoid burial and grape overwintering research directions. It also provides a theoretical foundation and technical support to improve grape yield and quality in northwest China.

Environmental sustainability has driven research into the development of biodegradable materials to address ecological challenges. In this study, biodegradable sprayable films were produced from thermally gelatinized cassava starch suspensions (5% w/v) to explore their potential application as protective coatings for agricultural soils. Starch gelatinization process was optimized to evaluate their feasibility to be applied by the spraying technique. Results showed that it is necessary to carry out a previous dilution of the gelatinized suspensions (1:4) to be able to spray them and form a uniform layer on the soil. To enhance films properties, it were introduced bentonite particles (0, 5, and 10% w/w starch basis) as reinforcement and sodium tetraborate (0 and 3% w/w starch basis) as crosslinking agent. A uniform bentonite particles distribution within the starch matrix was observed and films exhibited capacity to block UV and visible radiation, especially in the photosynthetically active radiation range. Tensile and puncture tests revealed that bentonite and borax presence increased the final films resistance, and biodegradability of the films was confirmed through water solubility and composting tests. The comprehensive findings from this study provide crucial insights for the implementation of eco-conscious innovations in crop cultivation and soil management techniques.

“…In particular, Huang et al found that in years with lower than normal precipitation, the water retaining effect of degradable film was lower and insufficient to offset the impacts of drought [12]. Liu et al also suggested that it is too early to promote degradable film based on their bibliometric analysis [13]. In contrast, Gu et al conducted a meta-analysis and showed that degradable film can potentially be used in northern China to eliminate the negative impacts of plastic film while also improving the yield and water use efficiency (WUE) [14].…”

Background: Traditional polyethylene film mulching is widely used in the Loess Plateau region of China to improve crop yields. However, whether long-term polyethylene film mulching can continue to ensure crop yield under future climate change conditions is questionable. First, we conducted a four-year field experiment to calibrate and validate the biogeochemical DeNitrification–DeComposition (DNDC) model. Then, based on the calibrated and validated model, we evaluated the spring maize yield and water use efficiency under different film mulching methods (no mulching, traditional polyethylene film mulching, and biodegradable film mulching) in the Loess Plateau region. Results: The temperature and rainfall in the Loess Plateau region are predicted to increase in the future (2021–2100) under four scenarios due to higher CO2 concentrations. Through 252 simulation results, we found that future climate change will have positive impacts under no mulching, traditional polyethylene film mulching, and degradable film mulching conditions. The yield increase will be greater with no mulching, but in the future, film mulching will continue to reduce crop yields. Additionally, the crop yield reduction under traditional polyethylene film mulching is greater. A sensitivity analysis indicated that rainfall will have a major effect on yield, and polyethylene film mulching will reduce the sensitivity of the yield to rainfall. As the rainfall increases, the differences between the yield and water use efficiency under ordinary plastic film and degradable film will become smaller. In the later period with a warmer and wetter climate under the SSP585 scenario, the water use efficiency will be higher under degradable film than traditional polyethylene film mulching. Conclusion: It can be seen that degradable film is more adaptable to the warmer and wetter climate in the future.
