Abstract
The present invention relates to a method for preparing water hyacinth organic fertilizers. A workstation for preparing water hyacinth organic fertilizers is established in a place where water hyacinth is centralized; fibriform scraps are obtained after water hyacinth is pulverized, extruded and eluted; then a small quantity of fowl and livestock droppings is mixed in the fibriform scraps for static fermentation; liquids produced after the water hyacinth is extruded are injected into fertilizers which are being fermented; granulation and packing are carried out after fermentation; and accordingly, finished products of water hyacinth organic fertilizers are obtained. The method is simple, water hyacinth is changed into valuables from waste, no sewage is discharged in the production process, and ecological environment is effectively protected.
Description
Technical field
The present invention relates to a kind of preparation method of fertilizer, be specifically related to a kind of preparation method of Herba Eichhorniae fertilizer.
Background technology
Herba Eichhorniae (Eichhornia crassipes) is commonly called as Herba Eichhorniae.Originate in South America,, be used as feed the fifties and introduce China because of it contains rich nutrient substances.But this kind weeds have extremely strong asexual multiplication ability, and under optimum conditions, its colony can increase the biomass of 20-30% every day.A large amount of Herba Eichhorniae covers the water surface, can cause that water body environment worsens, and causes hydrobiological minimizing, and stops up river course, obstruction shipping.Therefore, be one of the world's ten big malignant weeds by generally acknowledging at present.
In order to safeguard the cleaning of water body environment, many in the world countries and regions, all will drop into great amount of manpower and material resources and fund and salvage this kind weeds every year.With Shanghai City is example, and only 2002, the salvaging fund of cost was just above 8,000 ten thousand yuans.Even more serious is that the Herba Eichhorniae that salvages in a large number can't be handled: otherwise be transported to the locality and buried-this not only needs to spend a large amount of transport power, also needs to consume a large amount of soils; Being to abandon everywhere---this can cause second environmental pollution.Therefore, the Herba Eichhorniae that salvages being dealt carefully with, turned waste into wealth, is a job of benefiting the nation and the people.
The prosperous strong people that waits in the mound of Inst. of Hydrobiology, Chinese Academy of Sciences has proposed the fertile method for formulating of a kind of Herba Eichhorniae and azophoska compound compound.Concrete process is: with the cold water airing of Herba Eichhorniae to water content is 40-80%, with transfer roller deliver to the chopping workshop chaffcutter on be cut into 1-10 centimetre particle, on a kind of plain net airing 1-4 days then, be delivered to dry factory building drier 1-3 days, pulverize, mix in blender with nitrogen, phosphorus, potash fertilizer again.Though this kind method relates to the production that Herba Eichhorniae is used for fertilizer, not a kind of fertilizer zymotechnique, and 3 exsiccant steps are arranged, not only time-consuming but also consume energy.(a kind of preparation method of compound fertilizer, publication number 1267655; Classification number C05F17/00; Application number 99116385.0).
Summary of the invention:
The objective of the invention is at the deficiencies in the prior art, a kind of Herba Eichhorniae preparation method of organic fertilizer is provided, simple for process, can utilize Herba Eichhorniae to greatest extent, the product organic content height that makes.
For realizing such purpose, the present invention adopts the method for on-the-spot disposal, set up the workstation of Herba Eichhorniae organic fertilizer production in the place that Herba Eichhorniae is concentrated, Herba Eichhorniae is pushed, pulverizes, obtain fibrous fragment, sneak into a small amount of manure of livestock and poultry (pig manure, chicken manure, duck excrement or sheep excrement) then and carry out static fermentation, the liquid that Herba Eichhorniae extruding back is produced injects the fertilizer that is fermenting again, fermentation finishes and granulates, packs, and promptly obtains Herba Eichhorniae fertilizer finished product.
The idiographic flow of the inventive method is as follows:
In the river course or the bank in lake, select Herba Eichhorniae to concentrate the place of downloading, set up the workstation of Herba Eichhorniae organic fertilizer production.The Herba Eichhorniae of downloading is directly sent into water extracter and chaffcutter pushes and pulverizes, slough the liquid of 30-40%, obtain the fibrous fragment of Herba Eichhorniae, liquid enters in the cement pit stand-by.With Herba Eichhorniae fragment and manure of livestock and poultry (pig manure, chicken manure, duck excrement or sheep excrement) in 90: 10-98: 2 ratio uniform mixing, carry out static fermentation.After 10-15 days, the liquid that Herba Eichhorniae extruding back is produced injects the fertilizer that is fermenting.After 15-20 days, the fertilizer that fermentation finishes is granulated, packed again, obtain Herba Eichhorniae fertilizer finished product.
Herba Eichhorniae organic fertilizer production method of the present invention is compared with the method for formulating of other Herba Eichhorniae fertilizer, has tangible advantage and novelty: 1, product is to act on the fertilizer of producing by fermentation, but not Herba Eichhorniae mixes with the simple of inorganic fertilizer.2, Herba Eichhorniae is carried out " on-the-spot disposal ", in the river course or the bank in lake directly carry out processing treatment, can save a large amount of trucking costs.3, Herba Eichhorniae content helps the mass-producing utilization of Herba Eichhorniae up to 90-98%, thus help Herba Eichhorniae integrated management, turn waste into wealth.4, need not " drying " this step in the production technique, can save energy consumption and production time.5, the liquid that the Herba Eichhorniae extruding is produced refills in the fertilizer of fermentation, has not only improved nitrogen in the fertilizer, phosphorus, potassium and organic content, also accomplishes the production process sewage zero-discharge.6, the organic content height of product: organic content reaches 45%, is much higher than the Shanghai City provincial standard.Simultaneously, easier, the easy handling of production process.
Embodiment:
Below by specific embodiment technical scheme of the present invention is further described.
Embodiment 1:
