“…Potato is a shallow‐rooted and cool‐season crop, and temperature is the key factor that affects the tuber bulking and the balance between the vine and tuber growth of potato plants (MacKerron et al., 1986; Zhang et al., 2017). Potato growth is optimum when mean air temperature is around 15–18°C during the cropping cycle (Singh, Singh, Arora, & Sekhon, 2015).…”

Straw mulching is widely used in agriculture to conserve soil water and improve crop productivity. The effects of straw strip mulching and film mulching on dryland soil water storage and temperature, potato (Solanum tuberosum L.) growth and yield, and water use efficiency (WUE) were examined from 2014 to 2015 in the rainfed semi-arid regions of China. Field experiments were conducted with four treatments: (a) alternating strips mulched with maize (Zea mays L.) straw and bare plots with no ridges (SM); (b) alternating large ridges and small furrows with only the ridges mulched with black polyethylene film (PMP); (c) alternating narrows and wide ridges both mulched by black polyethylene film (PMF), and (d) traditional bare land planting without mulching (CK). The results indicated that film mulching had positive effects on soil water storage at the early stage of potato growth, while the SM significantly improved soil water storage at the late growth stage. Soil water storage (0-2-m depth) was 11.3-35.4 mm greater with the SM than that with the other treatments, especially during the tuber bulking in summer drought period. Compared with the CK, the SM significantly decreased soil temperature by 0.8-1.4 • C, and increased potato yield by 10.5-34.2%, WUE by 8.9-29.8%, and commodity rate by 14.7-38.8%. Compared with the PMP and PMF, the SM increased potato yield by 4.6-12.9 and 3.4-9.3%, respectively. This might be contributed to increased soil moisture and lower soil temperature, which promoted potato growth, yield, and commodity rates.Abbreviations: CK, traditional bare land planting without mulching; ET, evapotranspiration; PMF, narrow and wide ridges mulched by black polyethylene film; PMP, large ridges and small furrows only ridges mulched with black polyethylene film; SM, straw strip mulching; SWS, soil water storage; WUE, water use efficiency.

“…For the entire growth period, the reduction in K c under plastic mulch conditions ranged from 16 to 39 , with an average of about 27 , compared to no mulch conditions. Although the reported effects of mulching with plastic or straw on water utilization are often contradictory, likely due to differences in weather-, soil-, crop characteristics and water and fertilizer inputs Zhang et al, 2017 , literature reviews clearly indicate that mulching significantly improves the agro-hydrological performance, primarily yields and water use efficiency yield per unit water for many crops, compared with no-mulching Qin et al, 2015 . Compared to no mulching, the effect of plastic mulching on evapotranspiration and associated K c values is expected to diminish as the plant grows due to canopy cover of the soil, which decreases the amplitudes of soil heat flux and soil temperature Zhang et al, 2017;Farahani et al, 2008 . In the early growth stages, however, plant transpiration and soil evaporation under mulching do not attain saturation of intercepted sunlight and the magnitude and variation of K c are lower. Therefore, using K c reported by no mulching studies may overestimate evapotranspiration of plastic mulched cotton for 16 to 39 and this is mainly due to mulch-induced differences in the early development stages Table 2 .…”

Crop coefficient K c is a very useful and widely used variable in evapotranspiration estimation in cropland. Traditional methods in calculating K c are based on field water balance, which is limited by long measurement interval and small study area. In addition, there is the need for K c under new agronomy practice such as plastic mulching and drip irrigation in arid environments. This study calculated and analyzed K c of a drip-irrigated and plastic-mulched cotton field in Aksu Oasis of the arid Tarim River Basin, China, and its relationships with several crop-, soil-and management variables such as relative growth days RGD , leaf area index LAI , extractable soil water ESW , and irrigation, based on two years' observations. The results showed that daily K c varied within the range of 0.08 1.28, with an average of 0.54 for the entire cotton growth season, in 2013 and 2014. Compared to non-mulched condition already published, the K c of mulched cotton for the entire growth season decreased by 16 to 39 . The largest reductions in K c due to plastic mulch were found in the initial and developmental growth stage. K c could be calculated by a third-degree polynomial model in relation to RGD, which was satisfactorily validated and can be used in other studies under the same or similar pedo-climatic and management conditions. Cotton LAI and ESW were found to be important factors influencing K c , particularly their critical values of 3.0 in LAI and 0.5 for ESW. Moreover, the results showed that irrigation significantly increased K c , i.e., 29 on average, partly due to arid advection. This study provided up-to-date and detailed information on cotton crop coefficient under plastic mulching and drip irrigation conditions in arid environment, and it is useful for improved management of agricultural water resources.

“…Plastic film mulch has been widely used in agriculture, especially in arid and semiarid regions, since it can save soil water by reducing evaporation [1] and optimize the light and thermal environments for crops [2][3][4][5][6][7][8][9][10][11]. Accordingly, plastic film mulching can improve seed emergence [12,13], root growth [14,15], nutrient uptake [16], stem elongation [5,11], final yield and water use efficiency [17][18][19][20][21].…”

Plastic film mulch is an important agricultural technology to reduce water evaporation and modify the soil thermal conditions for crop production. The optical properties of plastic film mulch and the crop canopy growth are both key factors impacting soil heat transport in the soil-film-canopy-atmosphere ecosystem. In this study, a process-oriented model was developed to better understand the interaction among the plastic film mulch, potato (Solanum tuberosum L.) canopy growth, and soil thermal conditions. Canopy growth, photosynthetically active radiation transmittance, net radiation, soil heat flux, and temperature were monitored in a two-year plastic mulch field experiment in Wuwei (Gansu Province, China). Results showed that the simulation of daily soil surface temperature had a good performance with 2.8 and 1.5 °C of root mean square error (RMSE) for the transparent film mulch (TM) and black film mulch (BM), respectively. Moreover, the simulation of the daily net radiation and soil heat flux model indicated reasonable fluctuations with potato phenological development with the daily R2 ranging from 0.89 to 0.98 in 2014 and 2015 for the TM and BM treatments. It was shown that the canopy temperature under BM was greater than that in TM treatment, and the maximum value difference could be up to 7 °C during the early potato growing period, which implied that the BM may perform better in modifying the canopy thermal condition. The model could provide heat distribution information for plastic film choosing in potato field to avoid heat stress.
