The buffering of wetlands on flooding and drought,the filtration of wetlands,wetlands acting as source or sink of CO2,the purification of wetland plants and the effects of salt and human activities on wetlands are summar.

Buffer action to rice-soil ecosystem to Cu and As pollution;

This paper introduces a series of experiments regarding buffer effect and dynamic ad-sorption or desorption of phosphate conducted on the basis of the field survey and analysis of the Yangtze river estuary and Hangzhou bay.

The buffer effect of carbamide to pH value of the liming liquor were studied by the determination of pH value and electrical conductivity.

Responses of wheat to salt stress and mitigative effects of salicylic acid,aspirin on salt stress induced injuries were studied during the stage of seedling growth of wheat ( Triticum aestivum L.

To discuss the alleviation of silicon on low-phosphorus stress of maize, the capability of low phosphorus tolerance about 9 maize inbred lines and 7 hybrids was firstly screened and identified by hydroponic culture.
