Embodiment 1

[0025] Biological slow-release fertilizer formula: 60 parts by weight of biomass power plant ash, 10 parts by weight of wood vinegar, 10 parts by weight of urea, 5 parts by weight of ammonium phosphate, 5 parts by weight of potassium sulfate, and 10 parts by weight of wood tar.

[0026] Its production method is as figure 1 Shown:

[0027] Use the hay cutter to cut and pretreat forestry tree trunks, trunks, roots, bark, branches, crop straw, waste wood, woodware, scraps from wood processing plants, and weeds.

[0028] On the one hand, the processed primary raw materials are transported to the bucket elevator through the screw conveyor, and then continuously fed into the pyrolysis and carbonization furnace by the feeding system, and the drying and pyrolysis and carbonization are completed in the furnace in sequence, and finally crude gas and charcoal are produced. The gas can be separated by multi-stage condensation to obtain gas, wood tar and wood vinegar.

Abstract

The invention discloses a biological slow-release fertilizer prepared by using biomass ash and wood vinegar as raw materials and a preparation method, and comprises the following components in parts by weight: 40-60 parts of biomass ash, 10-20 parts of wood vinegar, 10-15 parts of wood tar, 10-20 parts of nitrogen source, 5-15 parts of phosphorus source, and 5-10 parts of potassium source. The biomass ash, wood acetic acid and wood tar are proportioned according to the set ratio, and nitrogen source, phosphorus source and potassium source are added according to the set ratio, and the obtained mixed material is granulated, rounded, sieved, and dried. The finished biological slow-release fertilizer is obtained. The biomass slow-release fertilizer of the invention not only has fertilizer efficiency, but also has the functions of sterilization, bacteriostasis, disease resistance and insect control, can effectively activate soil, increase soil nitrogen, phosphorus, potassium and trace elements, promote the reproduction of beneficial microorganisms, and improve soil The ability of fertilizer storage, water retention and moisture retention, reducing the amount of chemical fertilizers, improving soil resistance to pests and bacteria, and reducing environmental pollution.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a biological slow-release fertilizer prepared by using biomass ash and wood vinegar as raw materials and a preparation method. Background technique [0002] With the increasing non-renewable energy crisis, my country has vigorously promoted renewable biomass power generation technology in recent years, and the power generation using biomass such as rice husk, straw and fuelwood as raw materials produces a large amount of biomass ash, and it is increasing year by year. A large amount of biomass ash piled up like a mountain, occupying acres of arable land, resulting in waste of resources and environmental pollution. Biomass ash has a high pH value and contains a variety of plant nutrients K, Ca, Mg, P, etc. The content of heavy metals meets national standards. It can be applied to agriculture and forestry, but the biomass ash is directly spread on the land It will cause saliniz...
