- 摘要:
- 为促进中微量元素肥料在巨菌草及其他牧草中的推广应用,以巨菌草为供试品种,采用盆栽的方式,设计5个梯度的中微量元素施肥水平,通过测定巨菌草株高、叶茎比、产量和营养品质等指标,确定最佳的中微量元素施肥量。结果表明:当施肥条件为C3处理(450 g·盆-1)时,与对照组相比,施加中微量元素肥能显著提高巨菌草株高、叶茎比、产量和各个时期粗蛋白、粗脂肪、粗灰分含量和相对饲用价值,并有效降低中、酸性洗涤纤维含量。
- Abstract:
- In order to promote the popularization and application of medium and trace element fertilizer in the production of Pennisetum giganteum and other forage grass,taking Pennisetum giganteum as the test variety,five gradient medium and trace element fertilization treatment levels were designed by pot culture.The optimal medium and trace element fertilization amount was determined by measuring the plant height,leaf stem ratio,yield and nutritional quality of Pennisetum giganteum.The results showed that:when C3 treatment (450 g〖DK1〗·pot-1) was applied,compared with the control group,the plant height,ratio of leaf to stem,yield,crude protein,ether extract and ash contents and relative feeding value of Pennisetum giganteum were significantly increased by applying medium and trace element fertilizer.And effectively reduce the neutral detergent fiber content and acid detergent fiber content.
