中文摘要:

      为探究不同有机肥对高寒地区燕麦草产量及土壤肥力的影响，本试验共设置 ５ 个不同的施肥处理，生育期 120 d后测定了燕麦鲜草产量和干草产量，并分析了土壤的理化性质。试验结果表明：不同的有机肥对高寒地区燕麦草产量影响较大，燕麦鲜草产量结合播种施 1 号燕麦专用有机肥作基肥，在分蘖期追施 2 号燕麦专用有机肥处理组最高，为 82 000 kg/hm2，本试验生产的有机肥处理组次之。此外，经土壤化学性质检测，各处理组有机质含量均较施肥前有所增加，本试验生产的有机肥处理组有机质、全氮、全磷、全钾含量最高，说明以牛羊粪为原料通过益生菌发酵自制的有机肥可以有效提高土壤肥力水平。

英文摘要:

      This research aims to investigate the effects of various organic fertilizers on oat yield and soil fertility in alpine regions. Five different fertilizer treatments were used, and the fresh and hay yields of oats were measured after a 120-day fertility period. The physicochemical properties of the soil were also analyzed. The experiment results indicate that various organic fertilizers have a greater impact on oat yield in alpine regions. The highest yield of fresh oat was achieved by applying No.1 special organic fertilizer, as a base fertilizer, and No.2 special organic fertilizer during the tillering stage, which reached 82000 kg/hm2. The treatment group of organic fertilizers used in this experiment produced the second-highest yield. According to soil chemical property test, it was observed that the organic matter content of each treatment group had increased compared to the levels before fertilization. The treatment group that used homemade bio-organic fertilizers made from cow and sheep manure as raw material through probiotic fermentation had the highest organic matter, total nitrogen, total phosphorus, and total potassium content. This indicates that the use of homemade bio-organic fertilizers can effectively improve soil fertility.
