Technical field
The present invention relates to a kind of production equipment, particularly a kind of bio-fertilizer continuous producing apparatus.
Background technology
As chemical fertilizer effect is direct, effect is obvious, and the usual practice of modern agricultural production is still a large amount of all over the world at present
Rely on and chemical fertilizer, through 3 to five years be concentrated use in chemical substance after, the natural fertility of soil is with annual continuous
Apply chemical substance and be remarkably decreased.The result of this decline result in and must be gradually increased chemistry fertilizer for keeping high yield every year
The amount of application of material.So whole declines that expense increase and accelerate soil are had led to, in recent years some places
Organic fertilizer production is designed mostly for processing municipal refuse.Contain substantial amounts of rubbish in the fertilizer of this method manufacture, special
Be not some be difficult to digest chemicalss, so as to seriously destroy the ecosystem in farmland, unfavorable to soil, to crops
Growth is unfavorable, and in Asia, traditional compost method is packed together and is placed with Caulis et Folium Oryzae, fallen leaves, dish leaf, saw foam and muck etc.
Regular hour makes them be fermented into the fertilizer for being suitable to apply in farmland.Existing compost generally carries out compost in ventilation and sends out
Ferment, the compost time is 20 ~ 30 days, to carry out compost next time, the production that such method does not only take up after the completion of a compost again
Space is larger, be likely to result in composting process fermentation uneven, compost produce gas cause certain pollution to environment, and
These gases have certain facilitation to the production of compost next time, and existing method for producing compost is not by this part
Gas is used, and has the production gap of 20 ~ 30 days in process of production, and cost benefit is not maximized.
