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

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.
