叶面肥不同施用量对小麦产量性状的影响

Effects of Different Application Amounts of Foliage Fertilizer onWheat Yield Traits

为了筛选出适合小麦的叶面肥喷施用量,以小麦同舟55和同舟9号为材料,研究叶面肥三佳禾施用量对小麦产量性状的影响,并对小麦的各性状进行相关性分析。结果表明:在返青期和灌浆期各喷施1.2 kg/hm^(2)的量,同舟55和同舟9号的产量比对照分别增产16.11%和12.92%,喷施叶面肥株高降低,其他各性状不断升高。从同舟55和同舟9号各性状相关性分析来看,产量与株高呈负相关,与其他性状呈正相关,同舟55产量与穗长、穗粒数、千粒质量呈显著正相关;同舟9号产量与穗粒数、千粒质量和有效穗数呈极显著正相关,与穗长和叶面积呈显著正相关。因此,适合小麦同舟55和同舟9号叶面肥施用量为返青期和灌浆期各1.2 kg/hm^(2),穗粒数和千粒质量对小麦的产量影响较大。

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/hm^(2)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/hm^(2)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.
