Mitigating greenhouse gas of chemical fertilizer with farmland emissions through replacement organic manure in a temperate被引量：13
《Science Bulletin》2015年第6期598-606,M0003,共10页Haitao Liu Jing Li Xiao Li Yanhai Zheng Sufei Feng Gaoming Jiang 
jointly supported by the Key Strategic Project of the Chinese Academy of Sciences(KSZD-EW-Z-012-2);the National Science and Technology Support Program(2012BAD14B00)
Burning crop residues and excessive use of chemical fertilizers results in an enormous waste of bio- logical resources, which further weakens the potential capacity of the agro-ecosystem as a carbon sink. To explore t...

A PRELIMINARY INVESTIGATION ON FORECASTING THE CROP YIELD WITH SEA SURFACE TEMPERATURE DATA
《Chinese Science Bulletin》1983年第10期1399-1405,共7页赵四强 
The crop yield, particularly its increase or decrease in a wide area, is influenced by the weather and climate during its growth period. As is well known, weather is controlled by the atmospheric circulation, and the ...
