摘 要:研究了4个浓度的生物有机肥(0、50、60和70kg·667m-2)对墨西哥玉米(Zea mexicana)生长特性与牧草养分和饲用价值的影响。结果表明,随施肥浓度的增加,墨西哥玉米的叶长、株高、鲜干草产量、粗蛋白(CP)、粗脂肪(EE)、干物质消化率(DDM)、随意采食量(DMI)和相对饲用价值(RFV)均呈增加趋势,而其粗灰分(CA)、酸性洗涤纤维(ADF)和中性洗涤纤维(NDF)均呈降低趋势。This test studied effects of four biological organic fertilizer concentration [0 (CK), 50,60 and 70 kg . 667 m-2] for Mexico corn growth characteristics and grass nutrients and feeding value. The results showed that Mexico corn leaf length, plant height and fresh hay yield, crude protein (CP) and crude fat (EE), digestibility of dry matter (DDM), free feed intake (DMI) and relative feeding value (RFV) were increased significantly (P〈0.05), the crude ash (CA), acid washing fiber (ADF) and neutral detergent fiber were(NDF) reduced significantly (P〈0.05) with the increasing of the concentration of biological organic fertilizer. Therefore, biological organic fertilizer can increase Mexico maize yield, grass nutrients and feeding value.
