| 摘 要： | 为筛选适宜青海省东部农区推广的小黑麦( × Triticosecale Wittmack)与豆科牧草的混播组合及比例，采用裂区设计，研究了‘甘农2号’小黑麦与两种豆科牧草‘青建1号’饲用豌豆(Pisum sativum)和毛苕子(Vicia villosa)]不同混播比例(0?? 100、20?? 80、30?? 70、40?? 60、50?? 50、60?? 40、70?? 30、80?? 20、100?? 0)的混播效应。结果表明：从混播组合看，‘甘农2号’小黑麦与‘青建1号’饲用豌豆混播的平均鲜草产量(41.80 t·hm–2)最高；从混播比例看，‘甘农2号’小黑麦与豆科牧草50?? 50混播时平均鲜草产量(44.45 t·hm–2)最高，比小黑麦和豆科牧草单播平均分别提高了17.94%和17.53%；混播组合和混播比例间的交互作用表明，‘甘农2号’小黑麦和‘青建1号’饲用豌豆以40?? 60的比例混播时总鲜草产量(45.55 t·hm–2)最高，比小黑麦和饲用豌豆单播分别提高了20.09%和17.00%。相关分析表明，混播群体的鲜草产量与小黑麦株高呈显著正相关关系(P < 0.05)，与豆科牧草株高呈极显著正相关关系(P < 0.01)。因此，在青海省东部农区推荐‘甘农2号’小黑麦与‘青建1号’饲用豌豆以40?? 60的比例进行混播。

| Abstract: | This study investigated the optimum mixed seeding planting ratio of legumes and triticale in the eastern agricultural region of Qinghai Province. Herein, the effects of mixed cropping the feed pea Pisum sativum variety ‘Qingjian No. 1’ (Q1) and hairy vetch, sown with the triticale variety ‘Gannong No. 2’ (G2) at different mixing ratios (0???100, 20???80, 30???70, 40???60, 50???50, 60???40, 70???30, 80???20, 100???0) were evaluated. The results showed that the average fresh weight (41.80 t·ha–1) of G2 × Q1 was the highest among the tested treatments. The average fresh weights (44.45 t·ha–1) were the highest for the planting ratio of 50???50; the fresh weights of triticale and legume were 17.94% and 17.53% higher than their respective monocultures, respectively. For the interaction between the species combination and the mixing ratio, the best performing treatment was G2 × Q1, planted at a ratio of 40???60, with a total fresh weight of 45.55 t·ha–1; the fresh weights of triticale and P. sativum were 20.09% and 17.00% higher than their respective monoculture, respectively. The results of the index correlation study revealed that the fresh weight of the mixed population was significantly positively correlated with the plant height of both triticale (P < 0.05) and legumes (P < 0.01). In summary, we suggest for G2 and Q1, a mixing ratio of 40???60 is optimal for mixed cropping in the eastern agricultural region of Qinghai Province. |
