Antibacterial organic fertilizer and preparation method thereof

Abstract

The invention relates to antibacterial organic fertilizer. The antibacterial organic fertilizer comprises 33-36 parts of rape straw, 20-25 parts of wheat straw, 21-28 parts of soybean straw, 11-18 parts of cassava residue, 6-11 parts of antibacterial agent, 18-23 parts of diatomite, 48-53 parts of urea, 24-27 parts of potassium dihydrogen phosphate, 21-25 parts of ammonium bicarbonate, 14-17 parts of calcium superphosphate, 10-17 parts of potassium chloride and 11-13 parts of calcium ammonium nitrate. The antibacterial organic fertilizer has the advantages that the production cost of the raw materials of the antibacterial organic fertilizer is lowered effectively, and cost can be lowered by 50-60%; the rape straw, the wheat straw and the soybean straw are extracted and converted into the organic fertilizer, so that the environment pollution of the fertilizer can be reduced; the yield of a test field using the antibacterial organic fertilizer is effectively increased by 23.3-24.54%; the fertilizer can allow fruits to be full, bright in color and high in disease resistance, and antibacterial ability is effectively increased by 18-22%.

Description

technical field [0001] The invention belongs to the field of organic fertilizer production, and in particular relates to an antibacterial organic fertilizer and a preparation method thereof. Background technique [0002] Fertilizers can provide nutrients for crops and produce more agricultural products. Although the use of fertilizers is increasing, it is impossible for all kinds of chemical fertilizers applied in farmland to be absorbed and utilized by plants. The utilization rate of chemical fertilizers is low, and a large amount of fertilizers that are not absorbed by crops enter the environment after application, causing pollution to the environment, not only destroying land resources, but also posing a threat to human health. At present, the chemical fertilizers used in my country are mainly nitrogen fertilizers, while phosphate fertilizers, potassium fertilizers, and compound fertilizers are less. Long-term application causes soil nutritional imbalance and aggravates ...

Although the use of fertilizers is increasing, it is impossible for all kinds of fertilizers used in farmland to be absorbed and utilized by plants

The utilization rate of chemical fertilizers is low, and a large amount of fertilizers that are not absorbed and utilized by crops enter the environment after application, causing pollution to the environment, not only destroying land resources, but also posing a threat to human health

At present, the chemical fertilizers used in my country are mainly nitrogen fertilizers, while phosphate fertilizers, potassium fertilizers, and compound fertilizers are less. Long-term application causes soil nutritional imbalance and aggravates the depletion of soil phosphorus and potassium. It has antibacterial properties, and it will cause the loss of elements that promote plant growth. It cannot effectively fix nitrogen, decompose phosphorus, and decompose potassium, and will cause the loss of fertilizers.
