This article by field test data, analysis of ultraviolet radiation due to stratospheric ozone reduction, as well as composite with different potassium levels on growth, photosynthesis and transpiration of malting barley, yield, grain quality and other impacts

This article through the big field experiment observed data, has analyzed because the stratosphere ozone reduction causes the ultraviolet radiation enhancement as well as executes the potassium level to bond differently to brewer's barley aspect and so on growth growth, photosynthesis and transpirat
