| 摘 要： | 为筛选出适宜于青藏高原高寒地区种植推广的播种方式及播种行距，本研究以燕麦（Avena sativa）和饲用豌豆（Pisum sativum）为试验材料，探求其在混播、间作及不同行距下的生产性能及种间竞争关系。结果表明：混播处理生产性能优于间作处理，30 cm处理优于其他行距。混播草地土地当量比均大于1，具有混播优势，混播草地中燕麦与饲用豌豆的种间相容性较好，两者间促进作用大于竞争作用，行距为30 cm与25 cm时，燕麦的竞争能力大于饲用豌豆。综合评价显示，青藏高原高寒地区燕麦/饲用豌豆混播行距30 cm时效果最佳，干草产量最高，适于建植应用。

| Abstract: | In this study, we used oat (Avena sativa) and forage pea (Pisum sativum) as the test materials to investigate their production performance and interspecific competition under mixed sowing, intercropping and different row spacing in order to select the suitable sowing method and sowing row spacing for the alpine region of Qinghai-Tibet Plateau.The results showed that the production performance of the mixed sowing treatment was better than that of the intercropping treatment, and 30 cm treatment was better than the other row spacing. The interspecific compatibility between oat and forage pea in the mixed grass was better, and the promotion effect between the two was greater than the competition effect, and the competition ability of oat was greater than that of forage pea when the row spacing was 30 cm and 25 cm.The comprehensive evaluation showed that the best results were obtained at 30 cm spacing between oat/forage pea in alpine areas of the Qinghai-Tibet Plateau, with the highest hay yield and suitable for establishment applications. |
