Problems solved by technology

[0006] In agriculture, dolomite is mainly used as a neutralizer for acidic soil and as a raw material for breeding substrates. The calcium and magnesium elements in it are difficult to be absorbed and utilized by crops, resulting in a waste of resources.
At present, there is no calcium-magnesium fertilizer made of dolomite on the market

preparation example Construction

[0035] A preparation method of calcium magnesium biological organic fertilizer, it comprises the following steps:

[0036] Step 1, roasting of dolomite: roasting dolomite in a high-temperature roasting furnace at 1100-1250°C for 8-10 hours, and the obtained roasted product is ready for use;

[0037] Step 2, preparation of calcium magnesium bio-organic fertilizer: crush crop straw, pass through a 60-80 mesh sieve, and stir with dolomite roasted product, amino acid, humic acid fertilizer, and microbial functional bacterial agent, mix well, and mix well The material is transported to the granulator, extruded into particles with a particle size of 2-5mm, and then dried in the drying cylinder. The inlet temperature of the drying is 120-150°C, and the temperature of the material in the drying cylinder is less than 80°C. The final moisture (mass percentage) is less than 30%, then sieve the residue with a sieving machine, get the sieved material, and set aside.

[0038] Step 3, packi...

Abstract

The invention discloses calcium-magnesium biological organic fertilizer and a preparation method thereof. The calcium-magnesium biological organic fertilizer is prepared from the following raw materials in parts by weight: 50 to 800 parts of dolomite lime, 95 to 200 parts of organic components, and 4 to 6 parts of microbial functional bactericide. The preparation method comprises the following steps: step I, roasting dolomite: placing dolomite in a high-temperature roasting furnace, and roasting for 8 to 10 hours at 1100 to 1250 DEG C to obtain a roasted product for standby use; step 2, preparing calcium and magnesium biological organic fertilizer: compounding the roasted product obtained in step 1 with organic components and functional bactericide, and preparing the calcium and magnesiumbiological organic fertilizer in steps of mixing, granulating, baking and sieving; and step 3, packaging the calcium and magnesium biological organic fertilizer prepared in step 2. The calcium-magnesium fertilizer can be used as the natural calcium-magnesium fertilizer is easy to absorb by crops; the dolomite lime has the function of killing harmful microorganisms in soil to avoid or reduce the occurrence of diseases and insect pests. The calcium-magnesium biological organic fertilizer prepared in the invention can improve the soil, adjust the pH value of the soil, increase the crop yield andimprove the crop quality, and is simple in manufacturing process.

Description

technical field [0001] The invention relates to the field of fertilizers, in particular to a calcium-magnesium bio-organic fertilizer and a preparation method thereof. Background technique [0002] In recent years, due to the unreasonable application of chemical fertilizers, soil acidification, soil organic matter content decreased, soil beneficial microbial populations and numbers decreased. In addition to nitrogen, phosphorus, potassium and trace elements, crop growth also requires a considerable amount of calcium and magnesium elements. Due to continuous Cultivation, after the calcium and magnesium elements are taken away by the crops, they are not supplemented, resulting in the lack of calcium and magnesium elements in the soil, resulting in unbalanced crop nutrition, low utilization rate of chemical fertilizers, decreased soil fertility and physical and chemical properties, poor plant stress resistance, and stunted growth , yield and quality decline. [0003] Dolomite ...
