Effects of Different Application Amounts of Foliage Fertilizer on Wheat Yield Traits
In order to select the suitable foliar fertilizer application amount for wheast,this experiment used Tongzhou 55 and Tong-zhou No.9 as materials to study the effect of foliar fertilizer Sanjiahe application amount on wheat yield traits,and conducted corre-lation analysis on various wheat traits.The results showed that spraying 1.2 kg/hm2 during the greening and filling stages increased the yield of Tongzhou 55 and Tongzhou No.9 by 16.11%and 12.92%,respectively,compared to the control.Spraying foliar fertiliz-er reduced plant height,while other traits continued to increase.From the correlation analysis of traits of Tongzhou 55 and Tongzhou No.9,the yield was negatively correlated with plant height,but positively correlated with other traits.The yield of Tongzhou 55 was significantly positively correlated with panicle length,panicle number and thousand grain mass.The yield of Tongzhou No.9 was positively correlated with panicle number,thousand grain mass and effective panicle number,and was positively correlated with pani-cle length and leaf area.Therefore,the application amounts of foliar fertilizer for Tongzhou 55 and Tongzhou No.9 were 1.2 kg/hm2 at greening stage and filling stage respectively,and the number of grains per ear and the weight of thousand grains had a great influence on the yield of wheat.
