| 摘 要： | 为研究青海省适宜的禾豆混播方式，本研究以行距为30 cm,25 cm,20 cm和15 cm混播、间作、单播燕麦(Avena sativa)和饲用豌豆(Pisum sativum)两种饲草，分析研究不同混播方式下饲草产量及营养品质，以期为青藏高原高寒地区燕麦与饲用豌豆混播草地的建植提供参考。结果表明：间混作对饲草相对生长速率及饲草总产量均具有显著影响，其中混播处理的草产量高于间作处理。不同播种行距对饲草产量具有显著影响，饲草产量从高到低依次排序为：30 cm>25 cm>15 cm>20 cm。间混作对饲草营养成分具有显著影响，其中混播处理的粗蛋白含量高于间作处理，中性洗涤纤维含量低于间作处理，说明同行混播更有利于提高饲草品质；行距为30 cm与25 cm时，其各营养指标相对优于其他两个行距。通过合理的群体空间结构配置可以提高草产量，其中混播间距30 cm处理综合表现最优，其次为间作行距30 cm播种。

| Abstract: | The aim of this study was to provide a reference for the establishment of oats and forage peas mixed grasses in alpine areas of Qinghai-Tibet Plateau. We analyzed the forage yield and nutritional quality of oats (Avena sativa) and forage peas (Pisum sativum) in a mixed,intercropped,and single sowing with row spacing of 30 cm,25 cm,20 cm,and 15 cm. The results showed that intercropping had a significant effect on the relative growth rate of forage and total forage yield,with the grass yield of the intercropping treatment being higher than that of the mixed sowing treatment. Different sowing row spacing had a significant effect on forage yield,which was ranked as 30 cm > 25 cm > 15 cm > 20 cm. The intercropping had a significant effect on the nutrient composition of forage,in which the crude protein content of the intercropping treatment was higher than that of the intercropping treatment,and the neutral detergent fiber content was lower than that of the intercropping treatment,indicating that the intercropping was more conducive to improving the quality of forage;the row spacing of 30 cm and 25 cm was relatively better than the other two row spacings in all nutritional indicators. Grass yield could be improved by a reasonable spatial configuration of the population,with the best overall performance of the mixed sowing spacing 30 cm treatment,followed by intercropping row spacing 30 cm sowing. |
