摘　　要：以青引1号燕麦为研究对象,研究施肥对燕麦地上生物量和种子产量的影响。结果表明,从拔节期到成熟期,燕麦地上生物量,施肥处理高于对照CK处理,完熟期OPT处理最高,达99478.5 kg/hm2。施磷能显著提高燕麦种子产量。OPT+1/2P处理所得燕麦籽粒产量最大,为6678.3 kg/hm2。在施钾量和施磷量一定时,燕麦籽粒随施氮量的增加呈先增加后下降的趋势,OPT-1/2N处理所得籽粒产量仅低于OPT+1/2P处理,为6588.3 kg/hm2。The Qingyin No. 1 oat was as research objective to study effect of fertilizer on ab,~ve^ound biomass and seed yield of hull oat. The results showed that the aboveground biomass of oat with applying fe^ilizer was higher than that of CK treatment from jointing stage to maturity stage. The fresh grass reach highest of 99478.5 with OPT treatment in maturity stage. Applying phosphate fertilizer improve seeds yield of oat significantly. Seeds yicld reach highest of 6678.3kg with OPT ＋ 1/2P treatment . Under certain amount of potassic fertilizer and phosphate fe：silizer, seeds yield tend to increase, then decrease with increasing nitrogen fertilizer. Seed yield reach 6588.3 with OFF - 1/2N treatment, but less of OPT ＋ 1/2P treatment.
