Effects of Organic Fertilizer on Oat Yield and Soil Fertility in the Alpine Region of Gannan
This research aimed to investigate the effects of various organic fertilizers on oat yield and soil fertili-ty in alpine regions.Five different fertilizer treatments were set up,and the fresh and hay yields of oats were meas-ured after a 120-day fertility period.The physicochemical properties of the soil were also analyzed.The experi-ment results showed that various organic fertilizers had a significant impact on the yield of oat grass in alpine re-gions.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 82 000 kg/hm2,followed by the organ-ic fertilizer treatment group produced used in this experiment organic fertilizer produced in this experiment.In addi-tion,through soil chemical property testing,the organic matter content of each treatment group had increased com-pared to the levels before fertilization.The organic fertilizer treatment group produced in this experiment had the highest organic matter,total nitrogen,total phosphorus,and total potassium content.,indicating that organic fertil-izer made from cow and sheep manure as raw material through probiotic fermentation could effectively improve soil fertility levels.
