[Abstract]:In order to investigate the effects of bio-organic fertilizer on soil and crops, pot culture and oat pot culture experiments were carried out in Inner Mongolia Agricultural University in 2015 and 2016, respectively. The experiment was carried out in comparison with chemical fertilizer, organic fertilizer and biological organic fertilizer.The effect of biological organic fertilizer was compared with chemical fertilizer and organic fertilizer, chemical fertilizer and biological organic fertilizer.The main results are as follows: 1.The organic matter in the soil treated with bio-organic fertilizer was increased by 32.01g / kg, 6.12g / kg, 28.51g / kg and 5.41g / kg 路kg ~ (-2), respectively, after 155d cultivation, 74.40g / kg and 5.41 g / kg ~ (-1) 路kg ~ (-1) 路kg ~ (-1) 路kg ~ (-1) 路kg ~ (-1), respectively.The pH of soil was decreased, the pH of organic fertilizer treatment was 7.59, the pH of fertilizer treatment was 8.32, and the pH of oat cultivation experiment was 7.78 and 8.093respectively.The content of available phosphorus in soil was increased, the content of available phosphorus in soil was increased by 166.52% ~ 385.48%, and reached 21.07 mg / kg at 155d, 291.28 mg / kg ~ 560.98% and 13.55 mg 路kg ~ (-1) 路kg ~ (-1) 路kg ~ (-1) in grain filling period.The content of available potassium in soil was increased, the content of available potassium in soil was increased by the experiment of no crop cultivation, the content of soil available potassium was increased by 22.55% ~ 134.21%, and reached 378.81 mg 路kg ~ (-1) kg 路kg ~ (-1) after 155d cultivation, the experiment of oat cultivation increased 82.38% ~ 148.33%, and the grain filling period reached 101.99 mg / kg ~ (-1) 路kg ~ (-1).It promoted the propagation of soil bacteria, increased the number of experimental bacteria by 30.04%, reached 16.21,105 cfur / g at 105 days, increased the cultivation test of oats by 118.75% 312.50%, reached 2.31 106 cfur / g at 60 days, and promoted the propagation of actinomycetes.The number of actinomycetes increased by 207.65, reached 5.71,105 cfur / g at 105 days, and increased by 316.15 and 7.19105 cfugs. and increased the activity of sucrose enzymes at 75 days.The experiment of no-crop cultivation increased 329.20 and 489.19, and the highest was 8.79 mg/g / d, while the experiment of oat cultivation increased 36.36 and 294.74, and the highest was 0.75 mg/g d.6.The stem diameter and total yield of oats were the best under the combination of bio-organic fertilizer and chemical fertilizer, the stem diameter increased 130.13 and 133.95 mm, the thickest was 3.79 mm, the dry weight increased 803.31, and the highest yield reached 17.96g/ plant.In conclusion, the application of bio-organic fertilizer can improve soil fertility, increase soil available nutrients content, reduce pH, increase soil enzyme activity and bacteria, actinomycetes, and reduce the number of fungi.The mixed application of bio-organic fertilizer and chemical fertilizer is an effective way to reduce weight and increase efficiency.
