Regulative Effect Of Nutrient On Photosynthetic Potential Of Wheat Canopy Photosynthetic Organs And Output And Quality

Through the methods of field expeiment,chemical analysis and biological statistics,the effect of nutrient on photosynthetic organs,output,quality and regulation were systematically studied with Yong Liang NO.4.We make it clear that the effect of nutrient on the chlorophyl and area of the orgons of wheat;And make it clear that the output contribution of organs and the domino effect of output between no-leaf organs,beteen no-leaf organs and leaf organs;the effect of leaf and no-leaf organs on amylum,fat,proteid,ash,autanite,iron,zinc and vitamin.The results shows, comparing no-fertilization with fertilization,the chlorophyl of flag-leaf is the most in the no-phosphor borough(NK treats);but the chlorophyll of no-leaf organs is the most in the no-Potassium(NP treat);the fertilization can enhance leaf-area and no-leaf area;Cooperation use nitrogen,phosphor,Potassium can enhance 103 grains weight,grains dry weight per ear,No.grains per ear; the fertilization can enhance the content of amylum,fat,proteid,ash,autanite,iron,zinc and vitamin; comparing in gear wheat,after decreasing photosynthetic organs, the content of amylum,fat,ash and iron were decreased, the content of proteid,autanite,zinc were enhanced;But the number of content of vitamin depend on organs of wheat.
