    Abstract Smart irrigation systems are the focus of modern agriculture and have many engineering applications in China, in a still growing trend. According to the communication mode between the irrigation controller and the on‐farm execute devices, such as solenoids and sensors, irrigation controllers currently used in agriculture fields can be classified into three categories: (a) multi‐wire controller, (b) wireless controller, and (c) two‐wire decoder controller. The characteristics and application scopes of these three irrigation controllers are summarized and analysed; the result shows that the wireless controller and two‐wire decoder controller are more suitable for the large‐scale intensive irrigated agriculture in China. In addition, control of irrigation systems is gradually progressing from the conventional open‐loop mode to the closed‐loop mode, which can achieve precise irrigation decisions based on sensor feedback and crop water requirement model. Furthermore, non‐destructive testing technologies, such as crop canopy infrared temperature sensors and meteorological sensors, which can safely reflect crop drought or soil moisture over a large area are preferred as feedback sensors of irrigation controllers. More importantly, with the development of the internet, local operation of irrigation controllers is gradually being replaced by remote control, and then by comprehensive control and management, based on cloud computation. The application of internet technology can efficiently manage multiple irrigation controllers located in different places, make big data collections, share irrigation experiences, and make reasonable irrigation decisions much easier. This paper introduces the development of smart irrigation in China. © 2020 John Wiley & Sons, Ltd.

    Abstract Drainage water reuse has the potential to supplement irrigation, reduce drainage, and alleviate the area source pollution caused by agricultural drainage. This study aimed to evaluate the effects of influencing factors of drainage water reuse on supplementary irrigation and drainage reduction rates. To evaluate the effects, a water balance model was constructed to describe the irrigation water requirement and drainage water storage of a pond. The irrigation water requirement was calculated using the Penman-Monteith equation and the crop coefficient method while considering field leakage and effective rainfall; the drainage water volume was calculated using the improved Soil Conservation Service (SCS) model. The model was applied to the rice planting area in the Zhanghe Reservoir Irrigation District. Simulation results show that the supplementary irrigation and drainage reduction rates are primarily affected by the ratio of irrigation to drainage areas (RID), the pond volume ratio (PV), and the initial storage ratio (PSi); interactions among the three parameters are also observed. The RID, PV, and PSi contribute approximately 4:3:1 to the average variations in the supplementary irrigation rate. The supplementary irrigation rate increases with the values of PV and PSi but decreases with the increases of RID. For the drainage reduction rate variation, the average contribution percentages of PV and RID are 70% and 10%, respectively. Increasing PV and RID or reducing PSi enhances the drainage reduction rate. Adjusting the combination of parameters PV and RID can simultaneously maximize the supplementary irrigation and drainage reduction rates. Keywords: Drainage reduction, Drainage water reuse, Pond, Supplementary irrigation, Water balance model.

    Abstract Background: Mesenchymal stem cell (MSC) treatment plays a major role in the management of acute lung injury (ALI), and neutrophils are the initial line of defense against ALI. However, the effect of MSCs on neutrophils in ALI remains mostly unknown.
    Methods: We investigated the characteristics of neutrophils in lung tissue of ALI mice induced by lipopolysaccharide after treatment with MSCs using single-cell RNA sequencing. Neutrophils separated from lung tissue in ALI were co-cultured with MSCs, and then samples were collected for reverse transcription-polymerase chain reaction and flow cytometry.
    Results: During inflammation, six clusters of neutrophils were identified, annotated as activated, aged, and circulatory neutrophils. Activated neutrophils had higher chemotaxis, reactive oxygen species (ROS) production, and nicotinamide adenine dinucleotide phosphate (NADPH) oxidase scores than aged neutrophils. Circulatory neutrophils occurred mainly in healthy tissue and were characterized by higher expression of Cxcr2 and Sell. Activated neutrophils tended to exhibit higher expression of Cxcl10 and Cd47, and lower expression of Cd24a, while aged neutrophils expressed a lower level of Cd47 and higher level of Cd24a. MSC treatment shifted activated neutrophils toward an aged neutrophil phenotype by upregulating the expression of CD24, thereby inhibiting inflammation by reducing chemotaxis, ROS production, and NADPH oxidase.
    Conclusion: We identified the immunosuppressive effects of MSCs on the subtype distribution of neutrophils and provided new insight into the therapeutic mechanism of MSC treatment in ALI.

    Abstract Bacterial infection causes lung inflammation and recruitment of several inflammatory factors that may result in acute lung injury (ALI). During bacterial infection, reactive oxygen species (ROS) and other signaling pathways are activated, which intensify inflammation and increase ALI-related mortality and morbidity. To improve the ALI therapy outcome, it is imperative clinically to manage bacterial infection and excessive inflammation simultaneously. Herein, a synergistic nanoplatform (AZI+IBF@NPs) constituted of ROS-responsive polymers (PFTU), and antibiotic (azithromycin, AZI) and anti-inflammatory drug (ibuprofen, IBF) was developed to enable an antioxidative effect, eliminate bacteria, and modulate the inflammatory milieu in ALI. The ROS-responsive NPs (PFTU NPs) loaded with dual-drugs (AZI and IBF) scavenged excessive ROS efficiently both in vitro and in vivo. The AZI+IBF@NPs eradicated Pseudomonas aeruginosa (PA) bacterial strain successfully. To imitate the entry of bacterial-derived compounds in body, a lipopolysaccharide (LPS) model was adopted. The administration of AZI+IBF@NPs via the tail veins dramatically reduced the number of neutrophils, significantly reduced cell apoptosis and total protein concentration in vivo. Furthermore, nucleotide oligomerization domain-like receptor thermal protein domain associated protein 3 (NLRP3) and Interleukin-1 beta (IL-1β) expressions were most effectively inhibited by the AZI+IBF@NPs. These findings present a novel nanoplatform for the effective treatment of ALI.

    Abstract A large area of rainfed maize (L.) is planned to be replaced by maize under drip irrigation with plastic mulching (MDI) in Heilongjiang, northeast China, through a “water-saving and grain-increasing action” project. However, knowledge is lacking on the water requirements of maize under MDI. On the basis of a locally developed crop coefficient for a site, the spatial and temporal variations in crop water requirement (ETc) and net irrigation requirement (Nir) of maize under MDI in Heilongjiang were evaluated. The average ETc and Nir of maize under MDI in the period from 1960 to 2017 for 29 meteorological stations were 279 to 388 mm and 73 to 198 mm, respectively, which are approximately 10% and 15% lower than the ETc and Nir under conventional surface irrigation (NSI). The differences in ETc and Nir between the two irrigation technologies are significant in the southwestern region, which demonstrates that the intensive planning of MDI in the southwest is justified. The gross irrigation requirement of maize under MDI in an excessive drought year is estimated as 437 million m3 for the project, which is 137 million m3 less than the irrigation requirement using NSI.HighlightsAverage ETc and Nir of maize under MDI are approximately 10% and 15% lower than those under NSI.The differences in ETc and Nir are significant in the southwestern region of Heilongjiang.The estimated gross irrigation requirement of maize under MDI is much less than that under NSI.

    Abstract Considering the potential of cyclic irrigation to increase rainfall use efficiency and reduce agricultural non-point pollution, the experiment of phosphorus transport in paddy fields under cyclic irrigation of drainage water was conducted to address the problem of phosphorus loss pollution and the mismatch between rainfall temporal distribution and crop requirement in the south of China. Lotus pond water and fishpond water were used to irrigate paddy fields for monitoring concentrations of total phosphorus (TP), dissolved phosphorus (DP), and dissolved reactive phosphorus (DRP) in surface water and leachate, and soil profile total phosphorus and Olsen-P concentrations. The results showed that the concentrations of TP, DP and DRP in surface water and leachate decreased along the field under cyclic irrigation of drainage water, especially the phosphorus concentrations of leachate dropped more obviously. As the phosphorus content of cyclic irrigation water sources varied within a certain range, phosphorus concentrations of surface water and leachate did not increased. The concentrations of TP, DP and DRP in surface water and leachate varied with cyclic irrigation time, and the least phosphorus concentrations were observed in August. Top soil Olsen-P concentration decreased along the field and increased with phosphorus content of cyclic irrigation water sources, and soil profile TP concentration was not influenced by cyclic irrigation. Phosphorus removal ratio of paddy field could be increased by extending field length or cyclic irrigation in August.

    Abstract The accurate simulation or prediction of storm runoff is one of the most important bases of water resource management and environmental quality assessment of water and soil. The soil conservation service-curve number (SCS-CN) method cannot effectively determine the effect of antecedent precipitation storage and depletion on runoff, which limits the accuracy of the method’s runoff prediction. Thus, potential initial abstraction and decay constant were developed in this study to improve the SCS-CN method. Potential initial abstraction determined the maximum rainfall storage before runoff and the threshold of daily effective rainfall, and the decay constant was used to describe the dynamic depletion of antecedent daily effective rainfall induced by evapotranspiration and seepage. The improved SCS-CN method was evaluated withthe runoff data observed in four cropping systems and three drainage areas, and it proved that the improved SCS-CN method predicted runoff more accurately than the original SCS-CN method. The inproved SCS-CN method increased both NSE and R² values by more than 20 % for the four cropping systems, and increased R² values by 11.9, 13.9 and 9.6 % for the plot, field, and catchment, respectively, compared with the original SCS-CN method. The decay constant did not vary with cropping systems and drainage areas.

    Abstract A field experiment was conducted for 3 consecutive years (2007–2009) to study the effects of two different irrigation methods, that is, level-basin irrigation (BI) and drip irrigation (DI), and different treatment levels on crop growth, yield, and WUE of winter wheat (Triticum aestivum L.) in the North China Plain (NCP). The results indicate that irrigation methods and treatment levels had significant effects on crop growth and yield of winter wheat. Irrigation amounts significantly influenced plant heights, LAI, and winter wheat grain yields (P� <� 0.05 level) for both irrigation methods. Further, the DI method significantly improved yield and WUE compared with the BI method (P� <� 0.05 level) under conditions of deficit irrigation. Without irrigation system investment consideration, crop water productivity was highest when DI was used and irrigations were scheduled when soil water was depleted to 60 and 50� % of field capacity.
