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.
