Screening of Mixed Sowing Combinations and Interspecific Relationship between Oat and Annual Leguminous Forages in Horqin Region
摘要
Abstract
In order to screen out the optimal oat mixed-sowing combinations and planting ratio in the Horqin Area,this study used mixture of oat(Avena sativa L.)with forage peas(Pisum sativum L.),crimson clover(Trifolium incarnatum L.),and common vetch(Vicia sativa L.)to explore the effects of different oat-legume combinations and different seeding ratios on forage growth performance,yield,and nutritional quality.The results showed that:the combinations of oat-crimson clover and oat-common vetch achieved the highest hay yield at a 5∶5 seeding ratio.In contrast,oat-forage pea at 8∶2 ratio produced the highest hay yield,with a significantly greater system productivity compared with the other mixtures.The nutritional quality of the forage mixture improved with increasing legume proportion in the seeding ratio,whereas the oat-crimson clover mixture had lower nutritional quality compared with the other two mixtures.In the grass-legume interspecific relationships,oats were the dominant species which made the largest contribution to the total forage yield.In conclusion,the combinations of oats+forage peas,oats+crimson clover,and oats+common vetch achieved relatively high hay yields at seeding ratios of 8∶2,5∶5,and 5∶5,respectively,which were suitable for widespread planting in Horqin Region.关键词
