摘　　要：为探讨青海省海北州燕麦种植的最佳氮、钾施肥配比,研究不同氮、钾肥配比对燕麦产量构成要素、产量、品质和增产效应的影响。结果表明:在N_(100)K_(80)处理下,燕麦株高、穗长、单株茎重、单株叶重、叶茎比显著提高;在N_(100)K_(80)处理下,鲜草产量和籽粒产量显著高于其它处理,鲜草产量达到了33240kg/hm^2,籽粒产量达到了4640kg/hm^2;在N_(100)K_(80)处理下,燕麦粗蛋白含量最高为11.08%,灰分含量最低为3.02%;N、K肥在燕麦鲜草和籽粒上的增产效果为N>K。可为燕麦平衡施肥提供理论依据。To explore the best ratio of nitrogen and potassium fertilization on oat, a field experiment was conducted to research the different N 、K fertilizer on oat yield components, yield, quality and increase production effect in Haibei State Qinghai Province. The results showed that oat plant height, spike length, stem weight per plant, leaf weight per plant and leaf stems ratio increased significantly under N100 Ks0 treatment. Grass yield and grain yield increased significantly under N100K80 treatment, grass yield reached to 33240 kg/ hm2, grain yield increased to 4640 kg/hm2. Oat protein content as high as 11.08%, ash content in the lowest is 3.02% under N100K80 treatment. N and K fertilizer on oat grass and grain production effect for N 〉 K. It provides a theoretical basis for oat production and balanced fertilization.
