“…5). The most significantly elevated WUE T occurred during the vegetative stage (from transplanting to panicle initiation) rather than the reproductive stage (from anthesis to maturity), likely due to excessive growth during the vegetative period under GCRPS readily resulting in nitrogen deficiency during the reproductive stage (Qu et al, 2012;Tao et al, 2014). As an indicator of WUE T , stable carbon isotope composition (d 13 C) of leaves can provide a time-integrated measurement of a plant's transpiration efficiency, which reflects the averaged ratio of intercellular CO 2 and atmospheric CO 2 over a period (Farquhar and Richards, 1984;Ehleringer et al, 1993).…”

“…Over the last decades, several innovative technologies have been developed to reduce water consumption for rice cultivation (Peng et al, 1999;Belder et al, 2004;Liu et al, 2005). The ground cover rice production system (GCRPS), proposed in 1980s (Lin et al, 2002), has been found to reduce water application, enhance soil temperature, inhibit weed growth, and increase rice production Liu et al, 2005Liu et al, , 2013Tao et al, 2006;Li et al, 2007;Qu et al, 2012) and is therefore regarded as one of the most promising watersaving technologies for rice (IRRI, 2011). The GCRPS is currently applied on more than 4 million ha in China (Tao et al, 2015).…”

“…The GCRPS is currently applied on more than 4 million ha in China (Tao et al, 2015). In a GCRPS, strip soil beds are mulched by plastic film or crop straw, and rice, irrigated via the furrows between soil beds, is cultivated in predominantly unsaturated soil (Qu et al, 2012). However, knowledge regarding the water consumption and water-saving characteristics of GCRPS, essential for its improvement and application to irrigation scheduling, is insufficient.…”

“…Relative to TPRPS, significant limitation on leaf stomatal conductance has been observed under GCRPS due to drought stress Zhang et al, 2008Zhang et al, , 2009). In contrast, leaf area under GCRPS has been found to be greatly enlarged as a result of increased soil temperature (Tao et al, 2006;Xu et al, 2007;Qu et al, 2012). The overall effect of GCRPS on plant transpiration is therefore still unknown.…”

s u m m a r yThe ground cover rice production system (GCRPS) offers a potentially water-saving alternative to the traditional paddy rice production system (TPRPS) by furrow irrigating mulched soil beds and maintaining soils under predominately unsaturated conditions. The guiding hypothesis of this study was that a GCRPS would decrease both physiological and non-physiological water consumption of rice compared to a TPRPS while either maintaining or enhancing production. This was tested in a two-year field experiment with three treatments (TPRPS, GCRPS sat keeping root zone average soil water content near saturated, and GCRPS 80% keeping root zone average soil water content as 80-100% of field water capacity) and a greenhouse experiment with four treatments (TPRPS, GCRPS sat , GCRPS fwc keeping root zone average soil water content close to field water capacity, and GCRPS 80% ). The water-saving characteristics of GCRPS were analyzed as a function of the measured soil water conditions, plant parameters regarding growth and production, and water input and consumption. In the field experiment, significant reduction in both physiological and non-physiological water consumption under GCRPS lead to savings in irrigation water of $61-84% and reduction in total input water of $35-47%. Compared to TPRPS, deep drainage was reduced $72-88%, evaporation was lessened $83-89% and transpiration was limited $6-10% under GCRPS. In addition to saving water, plant growth and grain yield were enhanced under GCRPS due to increased soil temperature in the root zone. Therefore, water use efficiencies (WUEs), based on transpiration, irrigation and total input water, were respectively improved as much as 27%, 609% and 110% under GCRPS. Increased yield attributed to up to $19%, decreased deep drainage accounted for $75%, decreased evaporation accounted for $14% and reduced transpiration for $5% of the enhancement in WUE of input water under GCRPS, while increased runoff and water storage had negative influence on WUE (À7.5 and À3.7%, respectively) for GCRPS compared to TPRPS. The greenhouse experiment validated the results obtained in the field by simplifying the non-physiological water consumption processes, and thus confirming the relative importance of physiological processes and increased WUE under GCRPS.

Seasonal drought and low temperatures strongly limit rice (Oryza sativa L.) grain yield in the hilly areas of Southwest China. An integrated rice management (IRM) system was developed, which integrates ridge cultivation with plastic mulching, furrow irrigation, and triangular transplanting. A field experiment was conducted from 2011 to 2015. The effects of IRM on grain yield, yield components, soil moisture content (θ), and soil temperature (Tsoil) were evaluated. Compared with traditional rice management (TRM), IRM significantly improved grain yield by 29.9%. Furthermore, the yield of IRM (8181−9267 kg ha−1, CV: 7.6%) remained relatively stable. The rice tiller of TRM was highly related to the accumulated rainfall during the rice tillering stage in drought years (2011 and 2014). The water retention capability of IRM decreased the influence of interannual rainfall on rice growth and grain yield. In 2015, the θ in the 0−20‐cm layer was higher than the threshold for rice root growth over the rice‐growing season. Compared with TRM, Tsoil of the 0−20‐cm layer in IRM was 4.7 °C higher during the early tillering stage. The >10 °C soil effective accumulated temperature in IRM was also higher, and the difference was highest at the maximum tillering stage. The warming effect of IRM, particularly during the tillering stage, stimulated early growth and stronger tillering. In summary, the water retention capacity and warming effect of IRM were key factors for the improvement of rice yield; most importantly, the yields were stabilized in both drought and rainy years.

BACKGROUNDRice cultivation under film mulching with no flooding is widely used as an effective water‐saving technology. Different colors of film mulch have different effects on the soil hydrothermal environment and crop growth because of their different optical properties. However, the effects of different colors of film mulch on soil temperature and rice physiological growth are not clearly understood.RESULTSField experiments were conducted in 2019 and 2020 to investigate the effects of different color mulches on soil temperature and rice growth in a non‐flooded condition. Transparent film (TM), black film (BM), two‐color film (BWM, silver on the front and black on the back), and no film (NM) in a non‐flooded condition were designed. Soil temperature variation at different soil depths of 0–0.25 m and rice plant height, stem thickness, dry matter, yield and quality were monitored. The results showed that compared to no mulching, the mulching treatment effectively increased the average soil temperature during the whole rice growth stage with the soil temperature ranked TM > BM > BWM. Compared with NM, the BM and BWM treatments increased rice yield by 12.1–17.7% and 6.4–14.4% in 2019 and 2020, respectively. The BWM had 18.2% and 6.8% greater gel consistency than NM in 2019 and 2020, respectively.CONCLUSIONTransparent film should be applied with care because of the high soil temperature stress. Black film and two‐color film (silver on the front and black on the back) could be better option for rice yield, increasing and quality improving in a non‐flooded condition. © 2023 Society of Chemical Industry.
