Compared with DRT and SRT, NT lead to better work efficiency and lower seedling missing rate. In conclusion, NT could successfully improve sowing high quality, enhance soil liquid storage ability, reduce the risk of soil nitrogen leaching, and eventually enhance grain yield and ecological advantages in the growing stage of wheat plantation after rice.According to the two liquid globes theory (TWW), there’s two separate liquid swimming pools with different functions within the soil matrix, certain water world employed by flowers and cellular liquid globe added to runoff and groundwater recharge. The TWW theory differs from the others through the original hydrological design that soil water is completely mixed, and is of value for setting up new hydrological designs. Currently, the theorical basis and development circumstances of TWW hypothesis are unclear, with less reaserch from Asia. Here, we summarized analysis procedure, discrimination strategy, controversial points and prospect of TWW theory. You can find three views regarding the hypothesis help, partial support, and rejection. All evaluation methods are derived from hydrogen and oxygen isotope (2H, 18O) techniques, such as for example direct comparison, precipitation intersection point method, precipitation residual method, and precipitation migration technique. The representativeness of isotope examples of bound water and cellular water therefore the limitation of isotope technology may be the important cause of different results across all the studies. The development of methods distinct from stable isotope ones is a vital direction of future research. In addition, the theoretical basis of TWW hypothesis remains not clear, which will be the most crucial issue. The theory is mostly about a consistent ecological hydrological process coupling of precipitation, soil, and vegetation. Multi-disciplinary integration, multi-scale assessment and multi-factor analysis will be the effective approaches to learn this theory, and would be an essential research direction in the area of hydrology and ecology.To be green and renewable are crucial requirements for contemporary agriculture in Asia, with fertilizer input becoming one of several keys. Building and extending organic fertilizer happens to be a basic national plan for farming production in Asia for its eco-friendly and advantages in fertile farmland nurture. Organic fertilizer features broad supply and variety. The conditions for farming manufacturing are also mainly different. We examined the status of organic fertilizer services and products and stan-dards, real and chemical properties variations, variations of carbon and nitrogen mineralization faculties and their influencing elements. Meanwhile, we evaluated the results of application of natural fertilizer on basic soil fertility of cultivated land. As a result of variations in source and manufacturing process, different natural fertilizers vary within the four primary interior facets (the information of natural carbon portions, total N, energetic nitrogen and C/N) affecting carbon and nitrogen mineralization characteristics, including mineralization rates plus the level of offered nitrogen launch. Because of the influence of additional conditions such as edatope, various natural fertilizers vary in nutrient supply qualities. Overall, organic fertilizer somewhat increases earth natural matter content, particularly for labile natural matter content and carbon management index (CMI). More over, soil contents of nitrogen, phosphorus and potassium tend to be expanded. As a result, nutrient loss caused by crop growth is reduced, with positive effects on soil quality. The use of organic fertilizer on fertile farmland cultivate, the theoretical research of natural fertilizer, while the development of safe and efficient natural fertilizer items should be strengthened in the future, promoting the efficient recycling of organic fertilizer sources which could be a significant agricultural resource.Dryland agriculture, with wide distribution and high yield potential, plays an important role in guaranteeing food security in China. It’s presently tied to water scarcity, soil depletion, water and earth loss, and reasonable non-renewable resource-use effectiveness. Green manure gets the prospective to improve development environment of crops and advertise sustainable high-yield crops by increasing earth high quality, balancing earth nutritional elements, and improving soil water-storage capability. In inclusion, green manure has actually ecological advantages, including improving agroecosystem biodiversity, increasing soil surface cover degree, reducing inadequate nutrient loss to environment, increasing atmosphere balance of farmland systems, and biological control of conditions, insect pests, and weeds. Under current scenario of intensified global climate change, ecological deterioration, and agricultural product need changes, the standard agronomic strategies of utilizing green manure as a fertilizer cannot satisfy the demands of farming development. Thus, it’s important to strengthen the selection and bree-ding of green manure hereditary sources Rural medical education for dryland agriculture, to develop a brand new regionalization of green manure, and to establish a cropping pattern according to green manure suitable for various areas.
