“…The reasonable arrangement of gravel filter materials can effectively increase the water-collecting area of subsurface pipes. Soil water enters the gravel filter layer to reach saturation, and water will then enter the subsurface pipe without the groundwater table passing through the underground pipe (Bo et al, 2020;Salo et al, 2019). However, there was a shortage of gravel materials in the arid areas, such as Xinjiang, and choosing synthetic materials such as geotextiles as external filter materials could greatly reduce the engineering cost (Liu et al, 2013;Wu et al, 2006).…”

To investigate the dynamics and influencing factors of water and salt in subsurface pipe drainage (SPD) systems, three field experiments (denoted as E 0.8 , E 1.1 , and E 1.4 ) with different drainage pipe depths (80, 110, and 140 cm, respectively) were conducted in saline farmlands in the Xinjiang Autonomous Region, China. The cumulative water drainage and salt discharge were used to calibrate and validate the DRAINMOD model for simulating water and salt movements in SPD systems. Two indices, the effective leaching water amount (W e ) and the ratio of the salt discharge rate to the soil desalination rate (R s /N), combined with the water drainage rate (R w ) and salt discharge rate (R s ), were used to evaluate the effects of salt discharge under different pipe layouts. The experimental results showed that water drainage only started when groundwater completely submerged the subsurface pipes. Furthermore, R s and R s /N increased with decreasing burial depth, while the total salt discharge decreased and R w increased with W e . The relationship among W e , the burial depth of the subsurface pipe (B), the groundwater table (G), and the R w or R s /N of SPD was quantified under different soil textures. In addition, quantitative formulas for determining the water and salt discharge characteristics of SPD were also established.

“…As a typical cool, high-latitude, and rainfed area, Northeast China is one of the most important cultivated regions for cereal crops in China [ 2 ], with its spring maize planting area and yield accounting for approximately 30.9% and 34.0% of the country’s output [ 3 ]. In recent years, scarce precipitation and low temperature frequently occurred during the spring in Northeast China, representing the main limiting factors for increasing maize yield [ 4 , 5 ]. Appropriately increasing plant density (PD) is conducive to increasing stand leaf area index, enhancing the utilization of solar radiation, and improving maize yield and water use efficiency [ 6 ].…”

Film mulching in combination with high plant density (PD) is a common agronomic technique in rainfed maize (Zea mays L.) production. However, the effects of combining colored plastic film mulching and PD on dry matter accumulation (DMA) dynamics and yield of spring maize have not been thoroughly elucidated to date. Thus, a 2-year field experiment was conducted with three mulching treatments (no mulching (M0), transparent plastic film mulching (M1), and black plastic film mulching (M2)) and five plant densities (60,000 (D1), 67,500 (D2), 75,000 (D3), 82,500 (D4), and 90,000 plants ha−1 (D5)). A logistic equation was used to simulate the DMA process of spring maize by taking the effective accumulated air temperature compensated by effective accumulated soil temperature as the independent variable. The results showed that compared with M0 treatment, the growth period of M1 and M2 treatments was preceded by 10 and 4 days in 2016, and 10 and 7 days in 2017, respectively. The corrected logistic equation performed well in the characterization of maize DMA process with its characteristic parameter (final DMA, a; maximum growth rate of DMA, GRmax; effective accumulated temperature under maximum growth rate of DMA, xinf; effective accumulated temperature when maize stops growing, xmax; effective accumulated temperature when maize enters the fast-growing period, x1). Plastic film color mainly affected DMA by influencing xinf. PD mainly affected DMA by affecting GRmax and x1. During the first slow growing period, the DMA of M1 treatment was the largest among the three mulching treatments, however, during the fast growing period, the DMA of M2 treatment accelerated and exceeded that of M1 treatment, resulting in the largest final DMA(a) and yield. When the PD was increased from D1 to D4, the maximum growth rate (GRmax) continued to increase, and the effective accumulated temperature when maize enters the fast growing period (x1) continued to decrease, which substantially increased the final DMA(a) and yield. The application of M2D4 treatment can harmonize the relevant factors to improve the DMA and yield of spring maize in rainfed regions of Northeast China.

“…This wide range in N min potential demonstrates the necessity to better estimate the contribution of N min to crop N requirements, especially under brackish water irrigation. Bo, Li, & Li (2021) reported that quantification of soil N min would contribute to increased soil N availability and increased crop production under mulch irrigation. Hai et al (2015) reported that soil N min is essential for designing effective N fertilization strategies, which could improve N use efficiency and reduce nitrogen losses from agricultural systems.…”

Understanding the interactive effects of irrigation water quality and fertilization on nitrogen mineralization (N min ) and accurately predicting N min are of great importance for the secure and efficient utilization of brackish water in arid regions. A pot experiment was conducted to determine the N min under different drip irrigation water salinities and nitrogen application rates and to modify the nitrogen mineralization potential (N 0 ) and mineralization rate constants (k) of the first-order kinetic equation of N min . An in situ field experiment was conducted to validate the modified equation. The results showed that the amounts of N min for water salinities of 1.27, 3.03, and 4.90 g L À1 were 58.9, 76.1, and 45.4 kg ha À1 , respectively. N min was stimulated when the soil salinities were lower than 6.6, 6.1 and 3.9 g kg À1 for nitrogen application rates of 255, 315 and 375 kg ha À1 , respectively. Nitrogen application significantly reduced N min . When the nitrogen application rate increased to 375 kg ha À1 , the net N min rate remained lower, and the effects of salinity on N min were attenuated. The N min model with modified N 0 and k values was developed considering the impacts of soil organic nitrogen, nitrogen application rate, and soil salinity. Model testing indicated that the modified model provided an acceptable estimation of N min under field conditions. It will be helpful for developing rational fertilization strategies of drip irrigation with brackish water in arid regions.
