“…At our research site, the calculated potential evaporation was 167 mm during the fallow period between 2015 and 2016, and the observed precipitation was 121 mm. This result was consistent with previous research by Wu et al (2017) and Cai et al (2015) that suggested that mulching practices during the fallow season could relieve drought stress that occurs at sowing time and in the earlier stages of maize growth. However, we did not observe significantly different ET between PM1, PM2 and CK for the overall growing season.…”

“…After that, the volumetric water content (VWC) was obtained by multiplying the gravimetric water content with the bulk density and then divided by the water density. Soil water storage (W s ), evapotranspiration (ET), and water use efficiency (WUE) were calculated according to Cai et al (2015):…”

“…While climate conditions for dryland spring maize are usually characterized by strong evaporation and rare precipitation in fallow periods, they may limit the soil moisture conditions at sowing and even lead to yield failures (Cai et al 2015;Wu et al 2017). Wu et al (2017) proposed a whole season plastic mulching model to solve this problem and suggested that mulching practices during the fallow period relieved drought during the early stage of spring maize.…”

Abstract'One film for 2 years' (PM2) has been proposed as a practice to control the residual film pollution; however, its effects on grain-yield, water-use-efficiency and cost-benefit balance in dryland spring maize production have still not been systematically explored. In this study, we compared the performance of PM2 with the annual film replacement treatment (PM1) and no mulch treatment (CK) on the Loess Plateau in 2015-2016. Our results indicated the following:(1) PM2 was effective at improving the topsoil moisture (0-20 cm) at sowing time and at seedling stage, but there was no significant influence on soil water storage, seasonal average A c c e p t e d M a n u s c r i p t soil moisture or evapotranspiration; (2) PM2 induced significantly higher cumulative soil temperatures compared to CK, and there was no significant difference between PM2 and PM1; (3) no significant differences were identified in grain-yield and water-use-efficiency between PM1 and PM2, and compared to CK, they improved by 16.3% and 15.5%, respectively; (4) because of lower cost of plastic film, tillage, film laying and remove in PM2, economic profits improved by 21% and 70% compared to PM1 and CK. This research suggested that PM2 was effective at alleviating the spring drought and was beneficial in reducing poverty traps in dryland.

“…The increase in residual film had adverse effects on root, leaf, and stem of cotton, which led to a decrease in the number/size of cotton bolls. RPF at different densities have different effects on soil water movement, which influences the distribution of the matter in roots and other organs [38,39] , inhibits root growth, and reduces the contact area between root and soil. This may directly lead to abnormal growth and precocity of the cotton.…”

Long-term and widespread use of plastic mulching has led to the accumulation of residual plastic film (RPF) in farmland soils of Xinjiang, China. However, there is no specific quantitative basis for RPF pollution or a clear understanding of the influence of residual film on crop growth. The aim of this study was to investigate the effect of RPF on the growth of cotton, an important cash crop of Xinjiang. Based on the field conditions and previous reports, various amount of residual film was applied in 0-30 cm soil layer. The growth index including emergence rate, dry matter, and yield of cotton was examined at different growth stages under different soil residual film levels. Results demonstrated a significant effect of RPF on soil moisture distribution and movement. Plastic residues had a significant effect on cotton growth at levels above 200 kg/hm 2 , and the yield decreased as the RPF amount increased. Based on these findings, 200 kg/hm 2 was suggested as a threshold level to determine the effects of RPF on cotton. This study provided a basis to rate RPF pollution in farmland soils and help understand the impact of pollution on crop productivity.

Reducing soil evaporation is important to alleviate water shortages in arid and semi-arid regions. The objective of this work was to reveal the effect of straw mulch on soil evaporation based on field experiments during a freeze–thaw period in Northern China. Four soil surface mulch treatment modes were investigated: Bare soil (BS), 1 cm thick straw mulch with 100% coverage rate (J1), 2 cm thick straw mulch with 100% coverage rate (J2), and 2 cm thick straw mulch with 50% coverage rate (J3). Principal component analysis was used to analyze the major factors influencing soil evaporation in three freeze–thaw stages. The results show that cumulative soil evaporation decreased with increased straw mulch thickness and coverage rate. The effect of straw mulching on soil evaporation was obvious during the stable freezing period, and soil evaporation with straw mulch treatments was reduced by 49.0% to 58.8% compared to BS treatment, while there was little difference for straw mulch treatments in the thawing stage. The relationship between cumulative soil evaporation under different straw mulch modes and time was well fitted by the power function. In the unstable freezing stage, the major factors for all treatments influencing soil evaporation were surface soil temperature and water surface evaporation; in the stable stage, they were solar radiation and relative humidity, and in the thawing stage, they were solar radiation and air temperature. The research results can provide a basis for addressing soil water storage and moisture conservation and restraining ineffective soil evaporation in arid and semi-arid areas.
