| 摘 要： | 为研究不同配合比例的微肥对苜蓿草产量的影响,试验以Zn、Mn、Cu、B、Mo五种微肥作为试验因子,采用五元二次回归正交旋转组合设计,研究微肥对苜蓿干草产量的影响。结果表明:对苜蓿干草产量有显著影响的因子是锰肥和钼肥,有显著影响的交互项为锌肥与铜肥、锰肥与钼肥;而且在本试验条件下,施用较大量的锌、铜肥或施用较少的锌、铜肥苜蓿易获得高产,施用较少量的锰肥和钼肥,苜蓿可获得高产。通过模拟寻优得到微肥配施最佳方案为:Zn为10 kg/hm2,Mn为2 kg/hm2,Cu为2.5 kg/hm2,B为0.5 kg/hm2,Mo为75 g/hm2。建立了有关数学模型。

| Abstract: | Zn,Mn,Cu,B and Mo were applied to alfalfa field in the experiment and quadratic regression orthogonal rotational combing design with five factors was used to examine the effects of the experiment factors on hay yield of alfalfa and to establish the related mathematic models.The results showed that the factors which have a significant impact on alfalfa hay yield were Manganese and Molybdenum,the interactions which have a significant impact on alfalfa hay yield were Zinc and Copper,Manganese and Molybdenum.Lo... |
