Effects Of Applying Fertilizer On The Law Of Absorption Of Zinc,Selenium And Yield Quality Of Spring Wheat

Using the methods of field experiment,chemical analysis and biological statistics, effects of applying fertilizer on the law of absorption of Zn,Se and yield quality of spring wheat were systematically illuminated . Finding out the changing law of concentration , accumulation of Zn, Se at different growth periods and organs of the spring wheat and effect of spraying Zinc,Selenium;The absorption dynamic models of Zn,Se were established , based on this model, the greatest amount of Zn ,Se elements absorption rate and their appeared time were clear; Application of Zinc, selenium and ammonium hydrogen phosphate seed fertilizer all can increase the yield of the spring wheat , Meanwhile they had no significantly different on volume weight; This experiment provided the foliar application technology of enrich Zn Se on spring wheat ; The content of the crude protein and P,K,Ca,Mg,Fe,Mn,Cu,Zn,Se et nine mineral nutrient compositions of kernels,flour and wheat bran of spring wheat and affect of application fertilizer on their content were made clear ;Most of the crude protein and nine mineral elements of kernels were distributed in wheat bran , The higher of produce flour rate of kernels was by the first process , the more abundant content of the crude protein and mineral nutrition of flour were; Eating more flour all seed was scientific and healthy .It provides scientific and rational of production technology for enrich Zn and Se Superior quality green food spring wheat.
