中文摘要	采用3因素混合正交设计在宁夏盐池干旱区进行人工草地建植试验，连续2年对6个牧草品种的株高、密度及产量进行研究。结果表明：3因素中品种对株高和密度的影响较大，有机肥和氮磷钾对同一品种牧草株高及密度的影响较小。鲜草产量各因素的影响程度大小为：品种>氮磷钾>有机肥，这3个因素对产量影响极显著(P<0.01)，有机肥与氮磷钾的交互作用影响显著(P<0.05)。豆科品种的鲜草产量均大于禾本科，以草木樨产量最高，作为草田轮作牧草较好，其次是紫花苜蓿，可作为长期利用的优良牧草。正交设计得到鲜草产量的最优组合为草木樨+有机肥(36 t·hm~(-2))+氮磷钾中肥配比(N165 kg·hm~(-2)、P135 kg·hm~(-2)和K135 kg·hm~(-2))，与产量最高的处理15各因素水平完全一致，证实了正交设计结果的可靠性。
英文摘要	Based on 3-factor orthogonal designed experiment for artificial pasture planting in the arid area of Yanchi Ningxia, height, density and yield of 6 forages were studied in two consecutive years. The results showed that the effect of species on plant height and density was large, while effect of organic manure and NPK on the height and density of same forage species was small. The effect of each factor on perennial fresh yield was species > NPK > organic manure, the influence of these 3 factors on yield was significant (P<0.01), interactive effects of organic manure and NPK was significantly (P<0.05). The fresh yield of legume species was greater than the forage grass. Melilotus suaveolens has the highest yield, which is better as forage and crop rotation. Followed by Medirago sativa, which can be long term used as excellent forage. The optimal combination of artificial grassland is Melilotus suave olens. plus 36 tons organic manure per hectare and moderate levels of NPK, i.e., 165 kg of N, 135 kg of P and 135 kg of K per hectare. The level of each factor is consistent with treatment No.15, in which the yield was the highest. This proved that using the orthogonal test is reliable for the establishment of artificial grassland.
