| Abstract: | The effects of four different winter cover plants,ryegrass,Chinese milk vetch,rape and potato,on photosynthetic characteristics of double-cropping rice in southern China were studied in experimental field from 2008 to 2009.The results showed that compared with the CK(fallow in winter),the treatments of ryegrass,Chinese milk vetch and potato increased obviously the LAI,chlorophyll content and net photosynthetic rate in leaves of the double-cropping rice during the whole growth stages,raised the grain yield a... |
