Abstract
A compound organic fertilizer is prepared from the life garbage in urbon area through inoculating multifunctional microbes, aerobic fermenting and adding associated additives for improving fertility. A series of the said fertilizers for different plants can be prepared. Its advantages include high fertility, improving soil and eliminating environmental pollution.
Description
The present invention relates to the manufacture method of efficient composite organic fertilizer, is exactly a kind of composite organic fertilizer made of life garbage and manufacture method thereof specifically.
In recent years, because agricultural is used chemical fertilizer for a long time in a large number, cause soil fertility obviously to descend, even soil compaction occurs, the phenomenon that the optimum structure of soil is seriously damaged.Simultaneously, crops quality descends year by year, and mouthfeel is not good enough.Because the hazard residue thing is absorbed in a large number, and human health is caused very big threat, continues, the ecological agriculture will thoroughly be destroyed, and agricultural sustainable development becomes mere scrap of paper.Enter 21 century, population increases rapidly, ploughs and significantly reduces, and faces the agriculture situation of this sternness, and replacing chemical fertilizer with organic fertilizer is the task of top priority that is imminent.
China's reform and opening-up more than two decades, the city fast development, the quantity of domestic waste sharply increases.Along with the raising of cities and towns people's living standard, its mode of life is also corresponding to change, and causes the organic content of domestic waste showed increased thereupon.Fact proved that take " burning " or " burying " treating refuse, its disadvantage obviously exposes.Therefore, the processing of domestic waste must be walked the resource utilization road of pollution-free or less contamination.
The domestic waste organic composition is carried out compost fermentation, be degraded to organic fertilizer and can solve the deficiency that exists in other treatment processs.The domestic disposal site that has occurred some employing nature compost fermentations production fertilizers.But because N, P, the K ratio imbalance of domestic waste after becoming thoroughly decomposed, the C/N ratio is higher, thereby fertilizer efficiency is limited, and the natural composting process cycle is oversize simultaneously.Some bibliographical informations adopt the microbiological deterioration domestic waste to make fertilizer and artificial method of adding N, P, K chemical fertilizer, as " domestic waste fertilizer and the manufacture method thereof " of Chinese patent CN1107453A, matured compost behind the Secondary Fermentation is added chemical fertilizer make compound organic fertilizer.But this method is not added the biological flora (vinelandii, phosphate-solubilizing bacteria, potassium bacterium) that can improve fertilizer efficiency, self can decompose N in the soil, P, K in fertilizer, in fertilizer, do not add yet and to prevent and treat pathogenic micro-organism growth and breeding in the soil, reduce the biological control flora that corps diseases takes place.
At present in making composite organic fertilizer made of life garbage, still do not have and both adopted high-effective microorganism degraded domestic waste organic matter, the report that adds the vinelandii, phosphate-solubilizing bacteria, potassium bacterium and the biological control microbial bacteria that improve fertilizer efficiency simultaneously again in the organic matter that obtains the object of the present invention is to provide a kind of method that adopts the multifunctional microbial flora to make composite organic fertilizer made of life garbage.Its roughly process be: with having some microbiological deterioration domestic waste organism of quick degraded domestic waste in the multifunctional microbial flora, replenishing corresponding N, P, K and trace thereof in the organic matter that obtains does not have plain, add the biological control flora that has pathogenic micro-organism growth and breeding in vinelandii, phosphate-solubilizing bacteria, potassium bacterium and the control soil that improves fertilizer efficiency in the multifunctional microbial flora, reduces the corps diseases generation again, can obtain the very high compoiste fertilizer of fertilizer efficiency thus.Concrete grammar is as follows:
One, flora source and Microbiological Characteristics thereof

(2) fragmentation of organic waste
The application machine crusher carries out break process to compost material (organic waste), makes its raw meal particle size can be slightly larger than 5cm.
(3) mix and carry
In order to guarantee carrying out smoothly of " one time fermentation ", before fermentation, should make the parameters such as water content, C/N ratio of compost material up to standard, thorough mixing stirs then.Mass transport behind the mixing is to the place of compost.
3, the one time fermentation of domestic organic garbage
Use forced ventilation bar buttress composting process, its advantage is to reduce facility investment, reduces cost.This law is rubbish to be embarked on journey in the open or under the frame to spread out, and stockpile is high 2 meters, and is wide 4～6 meters, is provided with ventilator trunk and filtrate channel below the stockpile, and is furnished with bar buttress screening apparatus and stirs.
Microorganism species II level or III level seed with the degraded organic waste are inoculated in the material to be fermented in 0.1% ratio, carry out " one time fermentation ".During the fermentation, should control following fermentation parameter well: the C/N ratio is 25: 1～35: 1; Forced ventilation, making oxygen concn is 14～17%; Material moisture is 40～50%; Leavening temperature remains on 35～70 ℃; Be advisable in PH6.5～7.5.About 10 days of whole process.When temperature reaches 60～70 °, can make harmful organism death such as pathogenic micro-organism, parasite egg, reach innoxious standard.
The final index of one time fermentation is ordorless, reaches innoxious standard, volume decrement about 1/2, and moisture removal rate about 8%, volatile solid transformation efficiency about 15%, the C/N ratio is 15～20: 1.
4, sorting and fragmentation more again
The one time fermentation compost is carried out sorting again.The main mechanical sorting equipment that adopts carries out, and removes things such as remaining iron filings, plastics film.And compost material is broken for thin piece once more, its granularity is less than 1.2cm.
5, Secondary Fermentation
