“…In this study, the weight and projection direction value of CPCSQ were both the highest, which was beneficial to the quality indexes, which in the appropriate range to get the score. These results complement that of Liu et al (2019). The two methods get the same result, which is because the comprehensive weight and the best projection direction of the two methods are consistent.…”

An appropriate coupling of water fertilizer can improve the quality and yield of tobacco (Nicotiana tabacum L.). However, the optimal scheme of that is still unknown under the condition of effective microorganisms (EM) biochar-based fertilizer application. In this study, 12 treatments were set up, which were divided into four fertilization gradients (0, 100, 300, and 600 g pot -1 , represented CK1-CK3, T1-T3, T4-T6, and T7-T9, respectively), and each fertilization gradient had three irrigation gradients (40, 80, and 120 L pot -1 ). Each treatment was set in triplicate. Compared to CK, the nicotine content, reducing sugar, total nitrogen, potassium, chlorine, and yield of flue-cured tobacco increased by 13.22-48.87%, 1.53-13.46%, 7.68-29.23%, 7.73-21.76%, 6.48-34.55%, and 7.93-65.51% after the application of EM biocharbased fertilizer. The quality of flue-cured tobacco was less affected by the amount of irrigation (P > .05), and the yield was positively correlated with the amount of irrigation and EM biochar-based fertilizer (P < .05). The principal component analysis (PCA) was performed on all indexes of flue-cured tobacco quality and established the comprehensive evaluation system. Analytic hierarchy process-entropy weight method (AHP-EWM) and projection pursuit classification (PPC) algorithms were utilized to build the model, and the optimal water-fertilizer coupling scheme was selected according to AHP-EWM score and projection values. In conclusion, 120 L pot -1 irrigation combined with 100 g pot -1 of EM biochar-based fertilizer application treatment was the best water-fertilizer coupling scheme, and the AHP-EWM score and projection value were .632 and 1.169. The results of this study might provide theoretical and practical guidance for the plantation of flue-cured tobacco in production areas.

“…e trend of strengthening resource and environmental constraints has not yet fundamentally changed, and the task of optimizing economic development for environmental protection is still arduous [1]. At this stage, it is necessary to save natural resources, change the rough production method, and improve resource utilization and reduce pollution on the basis of scientific development, so as to achieve ultimately sustainable development [2]. With the maturity and rapid development of wireless communication, computer network, sensor network, and embedded and other technologies, people put forward the concept of the "Internet of ings," hoping to realize the seamless connection between people and things and things through the Internet and sensor network [3].…”

The Internet of Things is an emerging information industry. Applying the information collection, transmission, and processing technologies in the Internet of Things technology to environmental monitoring, environmental emergency, and other environmental protection supervision fields will greatly improve the speed and accuracy of environmental supervision and facilitate the scientific development of environmental protection. Through the Internet of Things, people can obtain a large amount of reliable real-time information, and it is not easy to be affected by time, place, and environment, while the wireless sensor network has the advantages of easy installation and low cost, so environmental monitoring through the Internet of Things is the future development trend. In this paper, in view of the current situation of water scarcity and serious water pollution in China, combined with the development trend and advantages of the Internet of Things (IoT), and based on the inadequacy of the existing microbial sensor data collection equipment, we propose a design scheme of microbial concentration monitoring system for waters based on IoT. The system is based on Zig Bee wireless sensor network to build a common data acquisition platform and design special hardware to carry out high-precision microbial sensor data acquisition in water and through the PC to complete the real-time measurement data storage, waveform display, and data processing. In this paper, the schematic diagram and PCB board design of the system hardware module NUC120 main control board, CC2530 RF board, Wi-Fi wireless communication module, and high-precision ADC acquisition module are completed and fabricated. Then, the four modules are combined to realize the development of the data aggregation node and data acquisition node of the dedicated Zig Bee wireless network hardware device.

“…RSM has been used to examine the combined effects of water and nutrient fertilizers on the growth and development of several plant species including Camellia sinensis (Wang et al 2016), Catalpa bungei (Qiu et al 2018) and Oryza sativa (Liu et al 2019). However, very few studies have so far focused on the simultaneous effects that water and nutrient fertilizers might have on the growth performance of desert shrub species in coal mining areas.…”

Coal-mined areas are often associated with hostile environmental conditions where the scarcity of water and key nutrient resources negatively affect plant growth and development. In this study we specifically addressed how different combinations of water (W), nitrogen (N) and phosphorus (P) might affect morpho-physiological and biochemical attributes of a native shrub species, Tamarix chinensis, grown on coal mine spoils. Our results show that under greenhouse conditions the application of moderate-to-high doses of W, N and P considerably improved growth-associated parameters (i.e. plant height, stem diameter, dry weight), as well as gas-exchange parameters, photosynthetic pigment contents and leaf water status of T. chinensis. Under field conditions high W and low N, P doses led to significant increases in plant growth-associated traits, gas-exchange parameters and leaf water status. Plant growth was generally higher under greenhouse conditions mainly because seedlings faced multiple stress when growing under field conditions. Low W-regime, regardless of N-P additions, improved osmotic adjustments in leaf tissues and also boosted the activity of several antioxidant enzymes to reduce the oxidative stress associated with W scarcity under greenhouse conditions. Importantly, our study shows how maximum growth performance of T. chinensis under field conditions was achieved at W, N and P doses of 150 mm year −1 , 80 kg ha −1 and 40 kg ha −1 , respectively. Our findings suggest that achieving optimal rates of W, N and P application is crucial for promoting the ecological restoration of coal-mined areas with T. chinensis under arid environmental conditions.
