2、照组。结果表明,海藻寡糖增效肥料(NKP)明显提高了玉米的肥料利用率及产量,且在海藻寡糖添加量为0.4%时,玉米的氮肥利用率、磷肥利用率、钾肥利用率,百粒质量及产量均达到最大,分别为73.59%,50.15%,26.60%,21.66,82.13g/盆,相对于常规对照处理分别提高了49.59%,52.85%,24.30%,16.45%,13.75%;而多肽添加量则为0.8%,0.4%,0.4%,0.2%,0.8%时,玉米的氮肥利用率、磷肥利用率、钾肥利用率、百粒质量、产量分别达到最大,分别为57.19%,41.03%,23.98%,20.81,77.34g/盆
3、,相对于常规对照处理分别提高了16.57%,25.05%,12.06%,11.88%,7.12%。因此综合比较,海藻寡糖对提高玉米肥料利用率及产量较好。关键词:海藻寡糖;玉米;NPK利用率;产量中图分类号:S513文献标志码:Adoi:10.3969/jissn.1671-9646(X).2013.11.021(1.CollegeofFoodScienceandEngineering,OceanUniversityofChina,Qingdao,Shandong266003,China;2.QingdaoFengtaiMarineBiotechnologyCo
