Mo、Co微肥配施对盆栽紫花苜蓿效应研究

采用盆栽试验，研究Mo、Co微肥配施对紫花苜蓿Medicage sativa生长发育、品质和微量元素含量的影响，结果显示：Mo、Co微肥配施能促进紫花苜蓿株高、草产量的增加，粗蛋白、粗脂肪、磷、钙等营养指标含量的提高，Cu、Mo、B、Zn、Co等微量元素含量增加，降低粗纤维、粗灰分、无氮浸出物的含量；而适当Mo、Co微肥配施能增加紫花苜蓿Mn含量，显著提高其株高、鲜草量及粗蛋白、P、Ca、Fe、Cu、Mo、Zn、Co的含量，显著降低紫花苜蓿粗纤维、粗灰分、无氮浸出物的含量

Studies on responses of potted alfalfa to trace element fertilizers application

 Pot experiment was conducted to study the effect of Mo、Co element fertilizers application on alfalfa growth, quality and trace element content. The results showed that combined application of Mo、Co fertilizers could increase Alfalfa height, forage yield and contents of crude protein, crude fat, phosphor, calcium, and contents of Cu, Mo, B, Zn, Co, reduce the contents of crude fiber, crude ash, nitrogen free extract; The appropriate combination of Mo、Co fertilizers could enhance the contents of Mn and significantly increase alfalfa height, fresh forage yield and the contents of crude protein, phosphor, calcium, Fe, Cu, Mo, Zn, Co, and significantly reduce the contents of crude fiber, crude ash, nitrogen free extract.
