Abstract
The j aponica super rice Longdao No .5 and Songjing No .9 and normal variety Mudanjiang 19 were used as materials to investigate canopy microclimate under different fertility levels .The results showed that the upright leaves of super rice could appropriate decrease of photosynthetic active radiation capture of the upper leaves ,increase the intensity of illumination ,and the light distribution was rational inside rice population .Pho-tosynthetic active radiation capture of each population reached almost the same ,but super rice had good plant type ,more sunlight was intercepted in middle-lower leaves ,temperature of population upward fast ,but the rela-tive humidity increased slow ,it favor for plant transpiration and net photosynthesis rate .Meanwhile ,Super rice had slower senescence of leave ,stronger photosynthesis produce capacity and a large amount of matter accumu-lation with high yield potential .关键词
