Description
Technical field
The present invention relates to the technical fields of organic fertilizer, more particularly, to a kind of sulfur-bearing organic fertilizer and preparation method thereof
And application.
Background technique
Chemical fertilizer is because cost is relatively low, efficiency is higher by universal use.But application chemical fertilizer can not only make
The physico chemical factor of soil degenerates, and hinders the breeding of septic biology in soil, threaten their existence, disorder soil
The ecosystem, consequence are that harmful parasitic organism is easy actively, to improve their population densities, to be then easy to more
Morbidity insect pest, and earth is made to pull knot, soil fertility reduces.
Although urea is organic matter, but it is a kind of nitrogenous fertilizer, and ingredient is single.Urea water after edaphon acts on
Solution belongs to quick-acting fertilizer at a kind of ingredient of ammonium carbonate.Urea will not bring organic matter to soil, will not promote microbial reproduction,
The physicochemical property and bioactivity that soil will not be improved, can reduce soil physico-chemical property and bioactivity, make soil after a large amount of uses
Earth is hardened.Simple N, P, K fertilizer is not able to satisfy the growing and cultivation of allium vegetables.
The breeding of beneficial bacterium in soil can be effectively facilitated by applying high-quality organic matter fertilizer, improved, provided or promote in soil
Beneficial bacterium generates nutrient necessary to crops, plays an important role to crop development, and rises to the ecosystem in soil
To good improvement result.But in existing organic fertilizer, such as livestock and poultry manure often with more various viruses, post
Infested ovum, foul smell etc., some organic fertilizers such as weeds etc. are often with various pest and disease damage infectious agents and seed etc., so general
If organic fertilizer can all be labeled with greatly discount without the processing of science, the good result of final organic fertilizer.Organic matter kind
Class is more various, between the different growing stages of different plants or same plant, need organic fertilizer it is organic
Matter content, the type of nutrient are different；And in existing general organic fertilizer compatibility, it is also possible to containing being not suitable for certain plantation
Certain ingredients of object, such as sea fertilizer etc. are often with higher to the harmful substance of growth of tea plant (such as chloride ion).Therefore, it is
The plantation and cultivation for realizing allium vegetables, the sulfur-bearing organic fertilizer for summarizing to obtain specific composition for Journal of Sex Research have important meaning
Justice.
Summary of the invention
The technical problem to be solved by the present invention is to overcome the technical deficiencies of existing organic fertilizer, provide a kind of sulfur-bearing organic fertilizer.
Another technical problems to be solved of the present invention are to provide the preparation method of the organic fertilizer.
The present invention is to provide the application of the organic fertilizer also with technical problems to be solved.
Above-mentioned purpose of the present invention is achieved through the following technical solutions:
A kind of sulfur-bearing organic fertilizer is provided, is made of urea, ammonium sulfate, diatomite and material mixing containing organic matter, it is described
The total content of organic matter is 57~57.8%, sulfur-bearing 2.4~3.4% in the sulfur-bearing organic fertilizer；The substance containing organic matter
For humic acid, bacteria residue, rapeseed meal；
The humic acid uses one of lignite weathering humic acid, fulvic acid, ulmic acid, humic acid；
The bacteria residue is that cotton seed hulls is cultivated remaining solid culture medium after bacterium；
Preferably, the total content of N content >=6.4%, N+P+K of the organic fertilizer is 10~11%.
Preferably, the N+P+K content in the bacteria residue is 3.53~4.53%；N+P+K content in the rapeseed meal is
0.4~0.5%.
Preferably, according to mass fraction meter, the sulfur-bearing organic fertilizer is made of in proportion following each component:
According to mass fraction meter, the organic fertilizer is made of in proportion following each component:
80 parts of urea；
120 parts of ammonium sulfate；
620 parts of bacteria residue；
50 parts of rapeseed meal；
80 parts of humic acid；
50 parts of diatomite.
Present invention simultaneously provides the preparation methods of the sulfur-bearing organic fertilizer, comprising the following steps:
S1. it is fermented to obtain rapeseed meal fermentation material after bio-fermentation agent being added into rapeseed meal；
Bacteria residue, humic acid and diatomite each component are pulverized and sieved, is mixed to get and is pulverized and mixed material；
S2. pH value is adjusted by rapeseed meal fermentation material and after being pulverized and mixed material mixing, then is mixed in proportion with urea and ammonium sulfate, wrapped
It fills or is packed after being granulated to obtain the final product；
The bio-fermentation agent is aspergillus niger microbial inoculum, bacillus subtilis, lactobacillus plantarum, one in EM microbial bacterial agent
Kind.
Preferably, the bacteria residue was crushed to 10~20 meshes；The humic acid crosses 20~100 meshes；The diatomite
It was crushed to 8~14 meshes.Preferably, the ratio between the bio-fermentation agent and rapeseed meal are 1:20~30.
Preferably, the technological parameter of fermentation described in step S1 are as follows: fermentation temperature is 55~60 DEG C, fermentation time be 10~
14 days, every turning in 4~7 days was primary.
Preferably, described in step S2 tune pH value be adjusted to pH value be 5.5~8；Further, it is preferable to using quality percentage
The sulfuric acid or quick lime that specific concentration is 5~10% adjust pH value.
The organic fertilizer is powdery or graininess.
The organic fertilizer can be advantageously applied to the base manure as fruits and vegetables such as leek, capsicum, apples.
Compared with prior art, the invention has the following advantages:
Sulfur content is high in organic fertilizer prepared by the present invention, has effectively facilitated the synthesis containing prot th in leek body, simultaneously
Sulphur is also the group ingredient of plant body fat enzyme, carboxylase, aminopherase, phosphorylase etc., promotes plant photosynthesis, is increased
Add nitrogen fixing capacity.In addition, there are also the effects for improving soil property for certain sulfur fertilizers, mitigate sodium ion to the danger of soil property and crop
Evil.
Lysine rich in organic fertilizer prepared by the present invention, macro- and trace-element, while it also contain it is abundant
Sulfur-containing amino acid, nutrient comprehensively uniformly it is hormone-free, be easy to absorb.The present invention utilizes the bacteria residue and humic of high organic content
On the one hand acid can provide the organic matter of high nutrient, and rich in member needed for all kinds of plant growths instead of human and animal excreta
On the other hand element avoids and brings odor pollution environment and disease to infect since excrement carries various viruses, parasitic ovum etc..
Meanwhile the ecological balance of soil can be maintained containing more organic matter in compound fertilizer prepared by the present invention, improve ecology
System.
Applying the leek of the complex fertilizer, growth rate is up to 26% compared to the control group containing Vitamin C content, protein content
Nearly 12% is increased compared to the control group, and soluble sugar content increases nearly 39%, and blade face width increases compared to the control group to be up to
40%, plant height also increases 43%, realizes that per mu yield growth rate is up to 15%, effect is considerable.
