2、不施肥和常規(guī)施肥為對(duì)照,施用中微肥大豆增產(chǎn)為14.5%和4.7%。差異達(dá)到顯著和極顯著水平。因此,中微量元素肥料的施用對(duì)大豆生產(chǎn)起到積極的促進(jìn)作用。關(guān)鍵詞:中微量元素肥料肥;大豆;生長(zhǎng)發(fā)育;產(chǎn)量中圖分類(lèi)號(hào):$565.1文獻(xiàn)標(biāo)志碼:A論文編號(hào):2013-1002EfectofIncreasingApplicationofSecondaryandMicro’。elementFertilizersonSoybean’SGrowthandYieldGaoXuedong,ZhuBaoguo,MengQingying,WangNannan,ZhangChunfeng,JiaHuibin
