A kind of fertilizer improveing soil and preparation method thereof
Invention field
The present invention relates to chemurgy field, concretely relate to a kind of fertilizer improveing soil and preparation method thereof.
Background technology
Fertilizer is to provide the mineral element that one or more above plants are required, improves a class material of soil property, level of increasing soil fertility, and is one of the material base of agricultural production.The complex fertilizer that China produces at present, mainly formed by chemical fertilizer compounds such as nitrogen, phosphorus, potassium, after shortcoming is life-time service, not only can make the situation aggravation of the pest and disease damage of crops, weeds also can be caused to grow wild, environmental pollution serious, make the soil ecology of crop culture lack of proper care, cause the phenomenons such as soil compaction, form the vicious cycle of agricultural, constrain the sustainable development of China's modern agriculture industry.The fertilizer of existing improvement soil simply can see the fertilizer impact on crops, can not reach effectively to improve to soil.Major part soil causes soil compaction owing to using chemical fertilizer, and lean soil is unreasonable due to fertilising, the most effectively improves the soil, thus causes not having harvest or in poor harvest;Particularly salt-soda soil accounts for sizable land area in China or even countries in the world, can not cultivate because of saline and alkaline laying particular stress on, and the substantial amounts of fund of also input having improves, and row's alkali presses down salt, but produces little effect.
Summary of the invention
For solving the problems referred to above, it is an object of the invention to provide a kind of fertilizer improveing soil and preparation method thereof.
The technical solution used in the present invention is:
A kind of fertilizer improveing soil, is formed by the preparation of raw material of following weight portion: bagasse 33-37, feces of livestock and poultry 50-60, humic acids 10-14, microorganism fungus kind agent 5-7, bamboo pulp 40-45, soy sauce residues 27-30, vinegar 38-42, fish pond mud 70-80, tenebrio molitor frass sand 20-30, kieselguhr 13-15, weathered coal 10-12, Fuji sand 5-7, meerschaum 8-13, oily anti-caking agent 10-14.
Described microorganism fungus kind agent is to be composited by the bacillus subtilis microbial agent of 30-40%, bacillus acidophilus's microbial inoculum of 20-30%, the Gram positive actinomycetes microbial inoculum of 10-15%, the azotobacter chroococcum microbial inoculum of 10-15%, the bacillus megaterium microbial inoculum of 5-10%, and above-mentioned percentage composition is weight percentage.
Described oily anti-caking agent is mixed by the primary octadecylamine acetate of the paraffin of 10-15%, the petrolatum of 15-20%, the Palmic acid of 20-30%, the stearic acid of 15-20% and 20-30%, and above-mentioned percentage composition is weight percentage.
The preparation method of a kind of fertilizer improveing soil, comprises the following steps:
(1) after bamboo pulp being pulverized, send in fermentation vat with bagasse, feces of livestock and poultry, humic acids, soy sauce residues, vinegar, fish pond mud, tenebrio molitor frass sand and add suitable quantity of water and be uniformly mixing to obtain mixed material, wherein the water content of mixed material is 55-65%, accesses microorganism fungus kind agent fermentation and obtains fermentation materials in 17-20 days;
(2) mix homogeneously after kieselguhr, weathered coal, Fuji's sand, meerschaum being pulverized, adds appropriate warm water, continues to stir, and high speed dispersion obtains slurry;
(3) put in drum-type mixing granulation machine after the slurry mix homogeneously in the fermentation materials in step (1) and step (2), and be passed through 70 DEG C of-80 DEG C of hot air dryings, obtain organic fertilizer particles;
(4) after the organic fertilizer particles obtained being cooled to 30-35 DEG C, screening, deliver in packing machine, oily anti-caking agent is uniformly sprayed on organic fertilizer particles surface, obtain improveing the fertilizer of soil.
Beneficial effects of the present invention:
Raw material wide material sources in inventive formulation, take full advantage of raw material common during daily life produces, while reducing production cost, reduce the usage amount of chemical fertilizer, more environment-friendly high-efficiency is balanced in nutrition, in addition to having azophoska, trace element, also has potentiation, the effect of promotion plant absorption nutrition, save farming cost, improve Crops production and quality.
Detailed description of the invention
Below in conjunction with specific embodiment, technical scheme of the present invention is further described.
Embodiment:
A kind of fertilizer improveing soil, is formed by the preparation of raw material of following weight portion (Kg): bagasse 33, feces of livestock and poultry 50, humic acids 10, microorganism fungus kind agent 5, bamboo pulp 40, soy sauce residues 27, vinegar 38, fish pond mud 70, tenebrio molitor frass sand 25, kieselguhr 13, weathered coal 10, Fuji's sand 5, meerschaum 8, oily anti-caking agent 10.
Described microorganism fungus kind agent is that the bacillus subtilis microbial agent by 35%, bacillus acidophilus's microbial inoculum of 25%, the Gram positive actinomycetes microbial inoculum of 15%, the azotobacter chroococcum microbial inoculum of 15%, the bacillus megaterium microbial inoculum of 10% are composited, and above-mentioned percentage composition is weight percentage.
Described oily anti-caking agent is mixed by the primary octadecylamine acetate of paraffin, the petrolatum of 20%, the Palmic acid of 27%, the stearic acid of 19% and 24% of 10%, and above-mentioned percentage composition is weight percentage.
The preparation method of a kind of fertilizer improveing soil, comprises the following steps:
(1) after bamboo pulp being pulverized, send in fermentation vat with bagasse, feces of livestock and poultry, humic acids, soy sauce residues, vinegar, fish pond mud, tenebrio molitor frass sand and add suitable quantity of water and be uniformly mixing to obtain mixed material, wherein the water content of mixed material is 55-65%, accesses microorganism fungus kind agent fermentation and obtains fermentation materials in 17-20 days;
(2) mix homogeneously after kieselguhr, weathered coal, Fuji's sand, meerschaum being pulverized, adds appropriate warm water, continues to stir, and high speed dispersion obtains slurry;
(3) put in drum-type mixing granulation machine after the slurry mix homogeneously in the fermentation materials in step (1) and step (2), and be passed through 70 DEG C of-80 DEG C of hot air dryings, obtain organic fertilizer particles;
(4) after the organic fertilizer particles obtained being cooled to 30-35 DEG C, screening, deliver in packing machine, oily anti-caking agent is uniformly sprayed on organic fertilizer particles surface, obtain improveing the fertilizer of soil.
Fertilizer test is carried out by maize planting in 5 mu of farmlands of equal fertility, every mu uses this product 160 kilograms, comparison uses the commercially available Common compound fertilizer of identical weight, is tested various nutrient concentration, yield and soil physico-chemical property after March of applying fertilizer, and comparing result is as follows:
