| Abstract: | Fram colture and field experiment showed that chlorophll content,Single leaf and Colony photosythetic rate was increased when potassium fertilizer was applied. 14 C-assimilate was Superior to transport and distribut into the centre of each growth stage when potassium fertilizer was dressed as soon as the transport vatio of assimilates was increased.$$$$ |
