为研究油菜钼营养的基因型差异及其特性，利用30个甘蓝型油菜材料，在大田试验条件下研究了钼肥施用对油菜产量、产量构成因子及钼吸收利用的影响。试验结果表明，施钼（钼酸铵0.75kg/hm2）显著提高了油菜苗期SPAD值、成熟期干物质重和产量，最高增加幅度分别为20.0%、29.5%、37.7%；施钼有增加大多数材料千粒重、降低多数材料单株角果数的趋势，而对果粒数影响不大，推测千粒重增加是施钼增产的主要原因之一。施钼显著提高了根、茎秆、角壳和籽粒等各部位的钼含量、单株钼含量和单株钼累积量，其中单株钼含量和单株钼累积量上升幅度分别为66.1%~88.2%和70.5%~87.5%。不同基因型油菜籽粒钼含量差异达5倍。说明存在高钼油菜资源，而且施用钼肥能提高油菜籽粒中钼含量。这为有效提高菜籽油中钼含量进而改善人体钼营养提供了可能。

To investigate the effects of molybdenum( Mo )fertilizer on different rapeseed( Brassica napus ) genotype,field trials were conducted using 30 varieties. Results indicated that SPAD value of rapeseed seedlings, dry matter weight and yield of matured plants were increased under Mo application( +Mo,ammonium molybdate 0. 75kg/hm2 )treatment. The maximum increase rates were 20%,29. 53% and 37. 68% respectively. The 1 000-seed weight was increased and pod numbers were decreased. No significant difference was observed in seed num-ber per pod between Mo application and control treatments( -Mo,zero ammonium molybdate). Mo application in-creased Mo content in root,straw,shell and seed. It also increaed plant Mo accumulation. Among them,plant Mo content and accumulation were increased by 6. 1% -88. 2% and 70. 5% -87. 5% respectively. Mo content differ-ences among genotypes reached 5 folds. It suggested that higher Mo content genotypes could be selected,and Mo fertilizer could be used to improve the rapeseed Mo content for human nutrition.
