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/hm2、120 kg/hm2、127.5 kg/hm2、135 kg/hm2、142.5 kg/hm2、150 kg/hm2,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/hm2 播种量为宜.
Abstract
In order to solve the problem of high sowing rate in the production of fodder oats,a compar-ative experiment of sowing rate was carried out with imported Baylor Ⅱ oats.The sowing rate was 112.5 kg/hm2,120 kg/hm2,127.5 kg/hm2,135 kg/hm2,142.5 kg/hm2,150 kg/hm2,a total of 6 see-ding 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 popula-tion 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/hm2 was the optimum sowing quantity in suitable environment and normal sowing time.
