  author={Meng-hua Xiao and Yuanyuan Li and Jianwen Wang and Xiu-jun Hu and Lei Wang and Zi-mei Miao},
The research on the effect of water-saving irrigation technology on the loss of nutrients and chemical substances in farmland has become a hot issue in the field of agricultural water and soil. Based on comparative experiments and combined with the isotope N15 tracer technique, the mechanism of nitrogen migration and transformation and the trend of fertilizer nitrogen use under different irrigation modes were studied. The results showed that water-saving irrigation modes (thin and wet…

Effect on Water Consumption and Non-Point Source Pollutants Loss under Different Water and Nitrogen Regulation of Paddy Field in Southern China
Irrigation methods and fertilizer application could affect water use and pollution transportation in paddy field. The results showed that water consumption for conventional irrigation was 22.3% and
Mechanism of water savings and pollution reduction in paddy fields of three typical areas in southern China
: Field irrigation and drainage regulation and fertilization application could affect water utilization and pollution transportation in a paddy field. In this study, representative rice-producing
Response of Vertical Migration and Leaching of Nitrogen in Percolation Water of Paddy Fields under Water-Saving Irrigation and Straw Return Conditions
The use of water-saving irrigation techniques has been encouraged in rice fields in response to irrigation water scarcity. Straw return is an important means of straw reuse. However, the
Effects of Water and Nitrogen Management on Water Productivity, Nitrogen Use Efficiency and Leaching Loss in Rice Paddies
Effective water and nitrogen (N) management strategies are critical for sustainable agricultural development. Lysimeter experiments with two deep percolation rates (low percolation and high
Effects of Water Stress on Fluorescence Parameters and Photosynthetic Characteristics of Drip Irrigation in Rice
To study the effects of water stress on the fluorescence parameters and photosynthetic characteristics of rice under drip irrigation and mulching, so as to determine the response mechanisms to water
Responses of photosynthetic characteristics of oat flag leaf and spike to drought stress
Raising crops production via improving photosynthesis has always been focused. Recently excavating and increasing the photosynthetic capacity of non-leaf organs becomes an important approach to crops


Microbial Activity in Paddy Soil and Water-Use Efficiency of Rice as Affected by Irrigation Method and Nitrogen Level
ABSTRACT The thin-shallow-wet-dry irrigation (TIR) method is one of water-saving irrigation methods of rice cultivation. The effects of TIR method on water-use efficiency (WUE) of rice and soil
Nitrogen and phosphorus changes and optimal drainage time of flooded paddy field based on environmental factors
Abstract While many controlled irrigation and drainage techniques have been adopted in China, the environmental effects of these techniques require further investigation. This study was conducted to
Influence of nitrogen loading and plant nitrogen assimilation on nitrogen leaching and N2O emission in forage rice paddy fields fertilized with liquid cattle waste
It is suggested that 100–258 kg N ha−1 is a recommended nitrogen loading rate for nitrogen recovery by rice plants without negative environmental impacts such as groundwater pollution and N2O emission.
Effects of alternate wetting and drying irrigation on percolation and nitrogen leaching in paddy fields
The widely adopted alternate wetting and drying (AWD) irrigation for rice production is increasingly needed to quantify the different water outflows and nitrogen leaching losses. We investigated the
Nitrogen and phosphorus loss and optimal drainage time of paddy field under controlled drainage condition
In order to reduce agricultural non-point source pollution and improve water use efficiency, the research on the change in ammonium nitrogen (NH4+-N), nitrate nitrogen (NO3−-N) and total phosphorus
Use of Nitrogen Isotope To Determine Fertilizer- and Soil-Derived Ammonia Volatilization in a Rice/Wheat Rotation System.
Two distinct variations in (15)N-NH3 and substantial soil-derived NH3 suggest that added N clearly interacts with the soil source contributing to NH3 volatilization, which is currently little evidence of the impact of added N on soil N losses throughNH3 vol atilization using ( 15)N methodologies.
