Description
Technical field
The present invention relates to organic fertilizer production technique, particularly relate to a kind of method of eucalyptus fertilizer special for organic.
Background technology
Eucalyptus has very strong transpiration, and water use efficiency is lower, and water consumption is very large, badly influences soil conservation, and they prove in the test of Lezhou Peninsula plantation, and the plantation of eucalyptus definitely result in the decline of ground water table.The plantation of big area eucalyptus can cause ground water table to decline, and earth's surface keeps the ability of water, and the time has been grown, and hardens in surface, soil, also occurs desertification of land phenomenon.
in recent years, China's pig industry develops rapidly, and because fermentation bed does not also carry out corresponding large-area popularization, cannot realize the pollution-free zero release of cow dung at present, thus cow dung generation is also increasing sharply.Cow dung contains abundant nitrogen, phosphorus, potassium and organic matter, is the good raw material of fertilizer.But meanwhile, also containing a lot of volatile matter, pathogenic micro-organism, parasitic ovum and heavy metal etc. in cow dung, if do not process and be directly applied to farmland, detrimentally affect can be brought to ecotope and human and livestock health.Cow dung as real organic fertilizer application in farmland, also will need fermentative processing.At present along with the development of biofermentation technique, utilizing cow dung to produce biological organic fertilizer becomes a new demand.
Summary of the invention
The present invention is directed to above-mentioned problem, a kind of method of eucalyptus fertilizer special for organic is provided.
For achieving the above object, the technical scheme that the present invention takes is:
Comprise the steps:
(1) batch mixing: by cow dung weight part 30-40 part of water content 70%-80%, maize straw weight part 60-70 part, adds fermenting agent, then adds plant ash and mixes adjustment water content, makes mixture water content be 50-60%;
(2) one time fermentation: step (1) gained mixture is transported to fermentation plant heap slivering buttress shape, the wide of each buttress is 1.8m, and height is 1.2-1.6m, carries out aerobic fermentation, and wherein summer, fermentation time was 15-20 days, and turning in every 2 days once; Winter, fermentation time was 25-30 days, and every 3-4 days turning once;
(3) Secondary Fermentation: carry out anaerobically fermenting by heaps for step (2) products obtained therefrom heap, fermentation time is 5-9 days;
(4) moisture regulates: the water content of step (3) products obtained therefrom is adjusted to 20-30%;
(5) pulverize and sieve: step (4) products obtained therefrom is carried out pulverizing and sieving process, make powdery or particulate state fertilizer.
Further: described fermenting agent is EM mix bacterium agent.
Further: described step (4) regulates the mode of water content adopt airing, air-dry processed or add auxiliary material.
Further: described auxiliary material is the one in plant ash, calcium powder, calcium superphosphate.
Cow dung of the present invention is just after separating dry space from moist space, through microorganism dynamically-continuous high temperature fermentation, microorganism is utilized rapidly the easy decomposition in starting material and the easy material producing foul smell to be carried out decomposing and transformed during the fermentation, and utilize the high temperature produced in decomposition course to play to kill pathogenic bacteria, destroy foul odors, reduce moisture content, reduce volume and weight, improve the object of available nutrient content simultaneously.
In composting process, carbon element is the basic energy derive of compost microbe, also be the basic material that microorganism cells is formed, compost microbe is while decomposition carbonaceous organic material, utilize part nitrogen to build own cells body, nitrogen still forms the important component part of protein in cell, nucleic acid, amino acid, enzyme, coenzyme.Rational carbon-nitrogen ratio is the prerequisite of highly effective compost fermentation, C/N is too high, sources of nitrogen needed for microbial growth is restricted, and microbial reproduction speed is low, and organic substance decomposing speed is slow, fermentation time is long, organic raw material loss is large, and humification coefficient is low, and composting production C/N can be caused too high, easily cause nitrogen starved plot after being manured into soil, thus affect crop growth.C/N is than too low, and the energy derive needed for microbial growth is restricted, and leavening temperature rises slowly, and nitrogen is excessive and discharge with the form of ammonia, and organonitrogen loss greatly, also can distribute niff.Carbon-nitrogen ratio in reasonable adjusting composting material, is accelerate compost maturity, improves the effective way of humification coefficient.Through long-term actual production and research experience, the C/N ratio of the present invention to cow dung compost is set to 28, utilizes less expensive and organic content is high, the maize straw of high adsorption capacity carries out carbon-nitrogen ratio adjustment for auxiliary material.
Keeping suitable moisture content in composting process, is the most important condition that compost is successful.Because microorganism mostly lacks water conservation mechanism, so very responsive to moisture.When moisture content is between 35% ~ 40%, the degradation rate of compost microbe can significantly decline, but when moisture drops to below 30%, degradation process can stop completely.Expansion deliquescing after usual organism water suction, is conducive to microbial decomposition; When moisture moves in compost, institute's carrier also can move to surrounding and spread, and creates conditions for the breeding of microorganism.Very little, microbial activities is restricted moisture, affects compost speed; Moisture is too many, can block space between compost material, affect its permeability, easily form anaerobic status, and produce foul smell, and nutrient loss is large, and compost is slow too.Keep suitable moisture and porosity to be the important means balancing composting process for this reason, ensure enough biologically stablies, suff water content must be had, but highly can not cause to because pore volume of freely ventilating reduces the state that oxygen transmission amount declines, and then reduce biological activity.Raw materials different in composting process has the different optimum moisture upper limits, and determined by the particle diameter of these raw materials and structural performance.Because raw aqueous rate of the present invention is very high, be keep higher fermentation efficiency, the present invention is according to a large amount of practical production experience, and in conjunction with the particle diameter of cow dung and structural performance, obtaining the optimum moisture content of raw material fermentation upper limit is 60%.By adding appropriate plant ash when not affecting C/N, raw aqueous rate is dropped to about 60%, for fermentation is laid a good foundation efficiently.
The present invention adds the EM mix bacterium agent of Japan in composting material, improves fermentation efficiency, shortens fermentation time, decrease the loss of nutritive element, make quality product higher.
What the present invention adopted is aerobic formula zymotechnique, for keeping efficiently carrying out of fermentation, must ensure to carry out sufficient oxygen supply to windrow.The industrialization compost generally unlikely naturally osmotic by air meets the needs of compost Biochemical reaction to oxygen, corresponding auxiliary oxygenation measure must be taked, conventional is take turning or forced ventilation mode at present, and what the present invention adopted at present is that mechanical turning mode carries out oxygenation.Bar buttress formula compost due to heap body and air contact surfaces greatly, generally just can be met the needs of its oxygen supply by turning.The frequency of turning is determined in conjunction with material properties and the change of heap temperature.
The temperature variation of compost is the index whether reflection fermentation is normal the most directly, the most responsive.To the requirement of the temperature variation of compost be: temperature rising in early stage is steady, high temperature maintenance in mid-term appropriateness, latter temperature decline slow.
The present invention regulates and controls the temperature of fermentation at present mainly through mechanical turning, namely at compost in earlier stage, even if fermented, temperature does not slowly even play temperature, necessary turning after 48 hours, heap body is avoided to form anaerobic environment, in the compost middle and later periods, once temperature exceedes set(ting)value, must in time turning, can not wait and reach turning again after setting-up time.
Compost work in-process enter follow-up further processing and packing stage after rotten degree detection, quality examination, safety detection.The product water ratio of compost maturity is still very high, need reduce below moisture to 30% and carry out follow-up processing again.What the present invention of moisture control method adopted is the methods such as natural air drying, airing, interpolation auxiliary material.
Pulverize and sieve to remove mechanical impurity to the windrow become thoroughly decomposed and make fertilizer form absorbing of the crop that is more conducive to of powdery.The fertilizer nutritive element that the present invention produces is very complete, in addition according to different crops demand, some trace elements can be added, according to different plant growth demands and special carry out surveying soil formula for various crop after add various water-soluble or Chelating state medium trace element as sulphur, iron, zinc, magnesium, calcium, boron, manganese, molybdenum, chlorine etc.
