Description
Technical field
The invention belongs to fertilizer preparing technical fields, and in particular to a method of quickly preparing organic fertilizer.
Background technology
In recent years, with scale, the development of centralization-breeding factory, agricultural modernization constantly propulsion and grain yield carry
It rises, the organic wastes yield such as farm animal excrement, agricultural crop straw is continuously increased.The year of the current farm animal excrement in China discharges
It is 4,000,000,000 t to measure, but its innoxious, recycling, commercialization disposition rate only 30% or so；National agricultural crop straw annual output is 900,000,000 t
Left and right, though resource utilization rate more than 69%, makees fertilizer with only accounting for 14.8%, either resource utilization rate or fertilizer
Utilization rate is all to be improved.
Farm animal excrement pollution is the most outstanding problem that current animal husbandry causes environmental pollution, mainly has cause of disease in excreta
Microorganism, parasitic ovum are not digested the organic matters such as the nitrogen utilized, phosphorus and various excess make an addition to mineral element in feed and
Drug and heavy metal, generated pernicious gas mainly have ammonia, hydrogen sulfide, carbon dioxide, phenol, indoles, scatol and methane
Class etc. not only pollutes farm itself environment and surrounding air such as without harmless treatment and recycling, and
And waste of resource.With the development of livestock and poultry breeding industry, the problem of environmental pollution of generation is quite severe.Livestock and poultry cultivation quantity is held
Continuous to increase, exhaust gas, wastewater discharge follow increase, and environmental carrying capacity is more and more limited, the livestock and poultry cultivation of technology and cost effective
Field wastewater treatment and the pattern of recycling are also not enough to cope with various types of livestock and poultry farm wastewater treatments.Livestock and poultry breeding industry
Generated problem of environmental pollution is present not only in the Animal Raising Zone of small scale and Relatively centralized, the livestock and poultry farm of scale
Face same problem.If animal epidemic influence be operator benefit, environmental issue has then been related to livestock and poultry cultivation
Can industry survive.With the appearance of national environmental protection policy, the environment protection treating of livestock and poultry breeding industry is proposed to be strict with, last year
The whole nation closes a large amount of environmental protection pig farm not up to standard, has seriously affected the numerous sow breeding stock of energy, or even play to pig price rising
Booster action, directly influences the living standard of the people.Therefore, environmental pollution caused by how quickly solving pig excrements is asked
Topic is extremely urgent.
By-product of the stalk as agricultural, the processing mode burned at present are more universal.It is released during crop straw burning
A large amount of CO2、CO、SO2, NOx, especially CO2, NOx these substances be the main source for leading to " greenhouse effects ".Crop straw burning
Other than discharging a large amount of pernicious gas, a large amount of inhalable particles are also generated, seriously endanger health, while also resulting in resource
Significant wastage.It is caused in " mist lock cities and towns " in city, PM10, PM2.5 increase 50% to 4 times, and air pollution index reaches severe
Pollution, local air pollution is caused in rural area.Open burning stalk generates volume of smoke and forms thick fog, and visibility is caused to decline,
Directly affect civil aviaton, railway, highway normal operation, bring hidden trouble of traffic.In addition, crop straw burning can also destroy soil knot
Structure causes farm land quality to decline.Because crop straw burning also enters three points of ground, the microorganism in earth's surface is scorched to death, humus, organic matter
It being mineralized, field crop straw burning destroys the balance of biosystem, changes the physical behavior of soil, has aggravated soil hardening,
Soil fertility is destroyed, arid is exacerbated, the growth of crops is thus affected.Crop straw burning is solved the problems, such as it is necessary to there is row
Effective solution scheme.
Implementation with country to fertilizer application amount policy of regulation and control, the Ministry of Agriculture advocate manure use and largely replace chemical fertilizer,
And it carries forward vigorously.China agro-technician it is believed that organic fertilizer preferably account for total fertilization amount 50% or so ratio,
High-yield field can be lower, and the ratio of chemical fertilizer and organic fertilizer is about 60:40, and low-yield land also answer it is some higher, chemical fertilizer with it is organic
The ratio of fertilizer is about 40:60.If by organic fertilizer and chemical fertilizer 1:1 applicating ratio, the annual requirement of China's organic fertilizer is 50,000,000
Ton or more, the market demand is huge.
With the structural readjustment of rural industry, great variety has occurred in farm's layout, and " Nan Zhubei is supported " has become industry hair
Exhibition trend, the Northeast have been increasingly becoming national livestock and poultry cultivation area of concentration, and concentration degree is also being continuously improved.But northeast ground
It is limited that the distinctive climatic factor in area causes the traditional zymotic that can be applied on the south Central Plains originally to prepare organic fertilizer technique.And it passes
The system organic fertilizer compost technology time is long, it is high to require, take up a large area, climatic factor influences that strong, decomposed degree is not easy to control etc. to be lacked
Point cause livestock and poultry farm be solve the excreta collection cistern built of environmental issue and fermentation vat do not only take up it is a large amount of cultivated
Ground also results in construction cost rising, and can not solve the problems, such as at all.Therefore, it is quickly made using farm animal excrement and stalk
Standby organic fertilizer technique becomes the important need of social development.
Currently, it is mainly fermentation method to prepare organic fertilizer using farm animal excrement and stalk, but since fermentation method is time-consuming longer,
Weather conditions are required, are taken up a large area, it is difficult to meet large-scale livestock and poultry farm especially large-scale pig farm the needs of.
