| 摘 要： | 利用酸性黄棕壤进行连续2年的盆栽试验,研究了钼肥和磷肥配合施用对甘蓝型油菜产量和子粒含油量、油产量、蛋白质含量、硫甙和芥酸含量以及脂肪酸组分等品质指标的影响。钼肥和磷肥各设置3个水平,分别为Mo 0、0.15、0.30 mg /kg土和P2O5 0、0.20、0.40 g /kg土,共9个处理。结果表明:施钼能够显著（P0.05）提高油菜子粒产量和生物学产量,显著增加油菜子粒含油量、油产量及油酸、亚油酸含量,降低子粒硫甙、亚麻酸和硬脂酸的含量;施磷则能够极显著提高子粒产量和子粒油产量,显著增加生物学产量和亚油酸含量,降低芥酸、硫甙及二十碳烯酸的含量;钼肥和磷肥对提高油菜子粒产量、油产量和油酸含量,降低芥酸含量存在显著（P0.05）的协同效应。因此,钼肥和磷肥在提高油菜产量、改善油菜子粒品质方面均具有良好的作用,且两者配合施用效果更好。

| Abstract: | Two years’(2006-2007 and 2007-2008) pot experiments with yellow-brown soil were conducted to investigate the interactive effects of molybdenum(Mo) and phosphorus(P) fertilizers on grain yield and oil content,oil yield,protein content,eucic acid and sulfuric glucoside contents and fatty acid composition of oil of Brassica napus seed.Both Mo and P fertilizers were applied at three levels(Mo 0,0.15,0.30 mg/kg and P2O5 0,0.20,0.40 g/kg) and nine treatments were formed.The results indicate that the grain yield and biomass,oil content,oil yield,oleic and linoleic acid contents of grains of Brassica napus seed are increased significantly under the application of Mo fertilizer,while the contents of stearic acid,sulfuric glucoside and stearic acid are decreased remarkably.The grain and oil yields,biomass and linoleic acid contents are significantly increased under the application of P,while the stearic acid,sulfuric glucoside and eicosenoic acid contents are markedly decreased.The Mo fertilizer and P fertilizer applications have remarkable synergistic effects on the improvement of grain yield,oil yield and oleic acid content,and the reduction of eucic acid content of rapeseeds.These results obtained in this study suggest that both Mo fertilizer and P fertilizer are conducive for the improvement of grain yield and quality of Brassica napus seeds,and co-application of Mo and P fertilizers has a better effect. |
