Using Sorghum bicolor x sudanense as test material, the effects of inorganic fertilizer and different proportions of organic fertilizer application on soil properties, yield and quality of sorghum were studied under conventional nitrogen application levels, aiming to provide data support for efficient production of green cycle forage. Five treatments were set up in the experiment, namely blank treatment (CK), conventional fertilization (HF), equivalent cow manure organic fertilizer (NF2), equivalent sheep manure organic fertilizer (YF2), 150% equivalent cow manure organic fertilizer (NF5) and 150% equivalent sheep manure organic fertilizer (YF5). In general, NF5 treatment was excellent in improving soil organic matter, enzyme activity and nutrient content, and the yield of Gaodan grass was significantly increased.
