播量对甘南高寒牧区饲用燕麦产量的影响

Effect of Sowing Quantity on the Yield of Avena sativa L.in Gannan Alpine Pastoral Area

摘要:

为筛选出适宜甘南高寒牧区种植的燕麦品种和最适播量,开展4个燕麦品种不同播量条件下的种植试验。从品种筛选结果看,青引1号、青引2号、林纳均表现出了良好的适应性和抗逆性,其中以青引2号最优,其次为林纳和青引1号。从经济成本、产量等综合来看,甘南高寒牧区燕麦饲草播量以300 kg/hm²为最佳。本研究成果对解决当地饲草匮乏,提高抗灾保畜能力,促进草地畜牧业可持续发展具有重要意义。

Abstract:

To identify suitable oat varieties and optimal sowing rates for planting in the high-altitude and frigid pastoral areas of Gannan,a planting experiments were conducted with four oat varieties under different sowing rates.From the variety screening results,Qingyin No.1,Qingyin No.2,and Linna have all shown good adaptability and resilience,with Qingyin No.2 being the best,followed by Linna and Qingyin No.1.In terms of sowing quantity,from the comprehensive perspective of economic cost and yield,the optimal sowing quantity for oat forage in the high-altitude pastoral area of Gannan is 300 kg/hm².The results of this study are significant for solving the shortage of local forage,improving disaster resistance and livestock protection capabilities,and promoting the sustainable development of grassland animal husbandry.
