Description

A kind of organic biofertilizer and preparation method thereof

Technical field

The invention belongs to technical field of fertilizers, particularly a kind of organic biofertilizer and preparation method thereof.

Background technology

In prior art, China mostly uses single fertilizer, composite fertilizer, organic and inorganic fertilizer in agriculture production at present in fertile.Owing to using mineral manure, high-concentration fertilizer etc. in a large number for a long time on soil, the decline soil fertility not only causing soil trace element keeps weak effect, soil total quality to decline, and also easily causes environmental pollution particularly water pollutions.In prior art, application number disclosed in 19 days November in 2015 is in the invention of 201410358775.6, propose a kind of method of bio-organic fertilizer, the method is that organic acid, stalk, trace element, monoammonium phosphate, ammonium molybdate, polypropylene, acid amides, Pericarppium arachidis hypogaeae meal, tea seed episperm, carbon granule, microbiobacterial agent, calcium superphosphate, the peat composed of rotten mosses, Repone K are mixed with according to certain ratio and are obtained.But the method exists improveing, and soil capacity is not good, long-term application can cause the defect such as soil gleying and nutrient owes lacks.For the problems referred to above, the invention provides a kind of organic biofertilizer effectively can increase soil fertility, avoid the extensive gleying of soil, effectively increase soil fertility.

Summary of the invention

In order to solve the problem, the invention provides following summary of the invention for this reason:

A kind of organic biofertilizer, comprise the raw material of following weight part: stalk powder 30 ~ 55 parts, wilkinite 20 ~ 35 parts, microbiobacterial agent 15 ~ 30 parts, trace element 10 ~ 25 parts, calcium superphosphate 8 ~ 17 parts, humic acid 3 ~ 7 parts, genus bacillus bacterium liquid 2 ~ 5 parts, 1 ~ 5 part, tensio-active agent, 0 ~ 3 part, tackiness agent.

Preferably, above-mentioned desinsection feed, comprises the raw material of following weight part: stalk powder 40 parts, wilkinite 30 parts, microbiobacterial agent 27 parts, trace element 20 parts, calcium superphosphate 16 parts, humic acid 7 parts, genus bacillus bacterium liquid 4 parts, 2 parts, tensio-active agent, 1 part, tackiness agent.

Present invention also offers a kind of preparation method of organic biofertilizer:

Concrete steps are as follows:

Step one, mixes raw material;

Step 2, first time fermentation: mixing raw material temperature in 4 ~ 7 days rises to 55 ~ 80 DEG C, and temperature reaches the fermentation that 80 DEG C of laggard line durations are 3 ~ 5 hours, and obtain leavening temperature afterwards and control at 45 ~ 65 DEG C, yeast phase is 10 ~ 22 days;

Step 3, second time fermentation: carry out second time fermentation after first time fermentation immediately, yeast phase is 7 ~ 15 days, temperature is 30 ~ 43 DEG C, to carry out between yeast phase turning over throwing, the number of times turning over throwing be every day at least one times, turning at every turn and throwing the time continued is 2 ~ 3.5 hours;

Step 4, carries out the fertiliser mixtures after fermentation screening of looking over so as to check, and after stirring, dries, gets product.

Conveniently use, feed is Powdered or particulate state.

Beneficial effect of the present invention: can effectively increase soil fertility, avoids the extensive gleying of soil, the organic biofertilizer of effectively increasing soil fertility, pollution-free nuisanceless, production process is simple, effectively promotes the raising of crop yield, has good promotion prospect.
