成都平原燕麦与箭筈豌豆不同混播模式对青贮品质的影响
The Effect of Different Mixed Sowing Modes of Oats and Common Vetch on Silage Quality in Chengdu Plain
摘要
Abstract
[Objective]This study is to investigate the effects of different mixed planting modes of Av-ena sativa L.and Vicia sativa L.on silage quality in the Chengdu Plain,to provide a theoretical basis for the mixed planting and storage of Avena sativa L.and Vicia sativa L.,and to offer a new approach for the effective utilization of winter fallow fields and the sustainable development of the forage industry in the Chengdu Plain.[Method]Unicast oats(CK1,sowing rate 83.00 kg/hm2)and common vetch(CK2,sow-ing rate 129.50 kg/hm2)were used as controls.Two mixed sowing methods[same row mixed sowing(T),cross row mixed sowing(Y)]and three mixed sowing ratios[oats∶common vetch=1∶1(1),3∶1(2),5∶1(3)]were employed for mixed sowing treatments.Silage was harvested directly at the oat milk ripen-ing stage and common vetch grain filling stage,and the quality of the silage was evaluated after 60 days of ensiling by opening the bags.[Result]The proportion of mixed planting significantly affected signifi-cant impact on the nutritional quality(DM,WSC,CP,NDF,ADF)and fermentation quality(pH,LA,PA,BA)of silage feed(P<0.01),while the mixed planting method significantly influenced the nutri-tional quality(CP,NDF)and fermentation quality(pH,AN/TN,LA,BA)(P<0.01).Under the experi-mental conditions,T1 and Y1 treatments ranked highest in terms of WSC,CP,LA,BA content,sensory evaluation total score,mean membership function comprehensive score,RFV,pH,AN/TN value,and other indicators;Under the same mixing ratio,same row mixing achieved higher RFV,CP,and LA con-tent,lower pH and AN/TN values,and superior overall silage quality compared to cross row mixing.[Conclusion]In actual production,same row mixed sowing is the preferred method,and the optimal mixed sowing ratio is oat∶common vetch=1∶1(sowing rate of 41.50 kg/hm2+64.75 kg/hm2).This model can be recommended for winter fallow field oat-common vetch mixed sowing and silage storage in the Chengdu Plain and similar regions.关键词
