摘　　要：针对饲用燕麦生产中播量偏高的问题,本研究选用引进的贝勒Ⅱ燕麦开展播种量对比试验,设置112.5 kg/hm^(2)、120 kg/hm^(2)、127.5 kg/hm^(2)、135 kg/hm^(2)、142.5 kg/hm^(2)、150 kg/hm^(2),共6个播种量处理。结果表明,适宜的播种量才能降低种植成本,获得质优量多的饲草,播种量过高,株丛群体庞大,不仅增加成本,且不利于燕麦群体结构的合理化,无效分蘖多,造成地力和种子的浪费。因此,选用生产性能优良、千粒重相近的品种,在适宜的环境条件和正常播期范围内,以112.5 kg/hm^(2)播种量为宜。In order to solve the problem of high sowing rate in the production of fodder oats,a comparative experiment of sowing rate was carried out with imported Baylor II oats.The sowing rate was 112.5 kg/hm^(2),120 kg/hm^(2),127.5 kg/hm^(2),135 kg/hm^(2),142.5 kg/hm^(2),150 kg/hm^(2),a total of 6 seeding treatments.The results showed that the suitable sowing amount could reduce the planting cost,obtain the forage with high quality and quantity,the sowing amount was too high,the cluster population was huge,not only increased the cost,but also was disadvantageous to the rational population structure of oat,and had more ineffective tillers,causing a waste of soil power and seeds.112.5 kg/hm^(2)was the optimum sowing quantity in suitable environment and normal sowing time.
