Abstract
The effect of nitrogen application on the yield and nutrients uptake of Avena sativa cv.Qingyin No.1 was studied.The results showed that fertilizer N significantly increased ear number,ear length,ear weight,seed number/ear,hey yield and seed yield(P0.05).The ear number,ear length,seed weight/ear,seed number/ear,hey yield and seed yield of Qingyin No.1 oats at 75kg N/hm2 reached the maimum,626.84 ears/m2,17.54cm,2.95g/ear,31.31grains/ear,20.71×103kg/hm2,6.49×103kg/hm2 respectively.The content of N,P,K in Qingyin No.1 oat increased with the rate of N applied.Agronomic efficiency,physiological efficiency and recovery efficiency decreased with the increase amount of N applied.
