| 摘 要： | 适量施Mo(施H2MoO4:0.33 kg/hm2),可以促进玉米对NPK的吸收,提高NPK肥料利用率(分别增加23.38%、26.52%和65.21%),增加单产(增产4.35%)及改变子粒品质;过量施用有抑制NPK在植株体内积累的趋势,与产量无益.玉米苗期营养体内全糖、可溶性糖和纤维素含量与施Mo水平呈正相关,蛋白N及叶片叶绿素含量呈负相关。

| Abstract: | The moderate application of Mo(H 2MoO 4: 0 33 kg/ha)in maize not only promotes the absorption to NPK, and enhances the fertilizer use efficiency of NPK (respectively increase 23 38%, 26 52%, 65 21%), but also increases the grain yield (increases 4 35%) and changes the grain quality The excessive application of Mo may inhibit the absorption of NPK and there was no good for the grain yield of maize The Mo supplying levels are positive correlativity with the content of total sugar, soluble sugar and fibre, but negative correlativity with the protein-N content of the plant and chlorophyll content of leaves at the seedling stage of maize |
