Residue and dynamic degradation analysis of Anilofos in paddy field system;

Field studies were conducted to investigate effects of rice straw incorporation and nitrogen application models on process of nitrogen uptake by rice paddy ecosystem and fertilizer-N use efficiency in the double rice cropping system.

Therefore, there is a carbon circulation within the rice paddy ecosystem.

Soil samples were collected from long-term monitoring plots of paddy field ecosystem in Hunan Province to study the evolvement characteristics and coupling relationship of soil organic carbon and total nitrogen under different fertilization practices.

The gas regulation function of rice paddy ecosystems and its value;

Effect of organic residues cycling on phosphorus nutrition in red paddy systems of south China;

The results of field experiments within 10 years in red paddy systems indicated the potential of recycling organic matters was significantly great.

Based on the data of long-term experiment during 12-year in Taoyuan Experimental Station of Agroecosystem Research of the Chinese Academy of Sciences, contribution of organic residue cycling to soil organic carbon and its effect on turnover of soil organic carbon was studied in red paddy system.

Studies on Potassium balance in purple soil rice field ecosystem;

A study on the biomass of rice field ecosystem during slack winter season in Xiangtan suburb;
