2、照組。結(jié)果表明,海藻寡糖增效肥料(NKP)明顯提高了玉米的肥料利用率及產(chǎn)量,且在海藻寡糖添加量為0.4%時(shí),玉米的氮肥利用率、磷肥利用率、鉀肥利用率,百粒質(zhì)量及產(chǎn)量均達(dá)到最大,分別為73.59%,50.15%,26.60%,21.66,82.13g/盆,相對(duì)于常規(guī)對(duì)照處理分別提高了49.59%,52.85%,24.30%,16.45%,13.75%;而多肽添加量則為0.8%,0.4%,0.4%,0.2%,0.8%時(shí),玉米的氮肥利用率、磷肥利用率、鉀肥利用率、百粒質(zhì)量、產(chǎn)量分別達(dá)到最大,分別為57.19%,41.03%,23.98%,20.81,77.34g/盆
3、,相對(duì)于常規(guī)對(duì)照處理分別提高了16.57%,25.05%,12.06%,11.88%,7.12%。因此綜合比較,海藻寡糖對(duì)提高玉米肥料利用率及產(chǎn)量較好。關(guān)鍵詞:海藻寡糖;玉米;NPK利用率;產(chǎn)量中圖分類號(hào):S513文獻(xiàn)標(biāo)志碼:Adoi:10.3969/jissn.1671-9646(X).2013.11.021(1.CollegeofFoodScienceandEngineering,OceanUniversityofChina,Qingdao,Shandong266003,China;2.QingdaoFengtaiMarineBiotechnologyCo
