| 【目的】探索箭等豌豆（Vicia Sativa L.cv）与春青稞（Hordeum Vulgare L.cv）在西藏山南地区的适宜混播比例，为当地混播人工草地的建植提供科学依据。【方法】以箭等豌豆和春青稞为试验材料，采用随机区组设计，研究了5种人工草地种植模式（V：100％箭等豌豆＋0％春青稞；VH1：70％箭等豌豆＋30％春青稞；VH2：50％箭等豌豆＋50％春青稞；VH3：30％箭等豌豆＋70％春青稞；H2O％箭等豌豆100％春青稞）的混播效果。【结果】混播可明显提高产草量和牧草品质，不同混播比例间的产草量及饲草粗蛋白（CP）、粗脂肪（EE）、中性洗涤纤维（NDF）、酸性洗涤纤维（ADF）、钙（Ca）和磷（P）含量差异显著（P〈0.05）；随着箭箐豌豆混播比例的增加，饲草粗蛋白、粗脂肪、Ca和P含量随之增加，而NDF、ADF含量降低。【结论】5种种植模式中，混播比例以50％箭等豌豆＋50％春青稞为佳，在该种植模式下，产草量较高，品质较好，土壤有机质、全氮和速效钾含量提高。该混播比例可以在西藏山南地区推广应用。 |

| Abstract: |
| 【Objective】 The study is to probe into the local suitable ratio and provide a scientific basis for the construction of mixed-pasture in Tibet.【Method】 Common vetch（Vicia Sativa L.cv） and spring barley (Hordeum Vulgare L.cv) as the experimental materials and randomized block design was used to study five pasture planting model(V:100% common vetch+0% spring barley);VH1(70% common vetch+30% spring barley);VH2(50% common vetch+50% spring barley);VH3(30% common vetch+70% spring barley);H(0% common vetch+100% spring barley).【Result】 The results showed that the vetch-barley mixture increased yield and quality of forage.There were significant differences in forage yield and the content of crude protein (CP),ether extract(EE),Neutral Detergent Fiber (NDF),Acid Detergent Fiber (ADF)，Ca and P among the different treats (P＜0.05);As the rate of vetch increased,the content of CP,EE,Ca and P increased but the content of NDF and ADF decreased.【Conclusion】 50% common vetch+50% spring barley was the best among the different mixtures,it has higher forage yield and better quality;Contents of soil organic matter,total nitrogen and available potassium of soil were increased in the experiment.This ratio could be commended to be popularized in the Shannan area of Tibet . |
