Abstract
The invention discloses an odorless organic fertilizer containing charcoal and a preparation method thereof. The preparation method comprises the following steps: soaking charcoal in a wood vinegar solution so as to obtain a deodorizer which takes charcoal as a carrier; adding the deodorizer into a compost raw material, adding a proper amount of water, and then performing fermentation composting; and after compost is in a thoroughly decomposed stage, drying the mixed fertilizer, and granulating to obtain the odorless organic fertilizer containing charcoal. The odorless organic fertilizer containing charcoal can be used for greatly improving the soil organic matter content, effectively improving the soil structure and improving the moisture and nutrient retaining capability of soil. During an organic fertilizer production process, the deodorizer is added, so that not only is the composting process rapidly and efficiently performed in an environment-friendly manner, but also the user effects of the charcoal and the organic fertilizer are obviously improved; the charcoal is added into the compost raw material, so that the composting temperature can be well kept, the microbial growth is promoted, and therefore the composting period is shortened; and more importantly, the charcoal is capable of effectively absorbing ammonia and hydrogen sulfide, so that nitrogen and sulphur losses in the composting process are reduced.
Description
Technical field
The present invention relates to a kind of fertilizer, particularly a kind of odorless fertilizer that contains charcoal and preparation method thereof.
Background technology
In China's agriculture production and livestock industry production process, produce up to biomass class solid waste such as 800,000,000 tons of stalks and 400,000,000 tons of fowl and animal excrements every year, a large amount of biomass solid wastes has produced a series of environmental problem in processing or disposal process, as the atmosphere polluting problem of crop straw burning generation, foul smell and water pollution problems that discharge fowl and animal excrement produces, on the other hand, stalk and fowl and animal excrement all contain abundant organic matter, fowl and animal excrement also contains abundant nitrogen and phosphorus, can be for improving soil nutrient.Yet, agriculture production at present too emphasizes to improve grain yield, use in a large number chemical fertilizer and agricultural chemicals, the use of fertilizer can not get effective attention, the chemical fertilizer that these are excessive and agricultural chemicals not only can not get effectively absorbing and utilizing, also have a large portion to enter water body and cause serious widespread pollution from the overuse of fertilizers and pesticides in rural area, excessively use chemical fertilizer and also very easily cause degradation problem under soil compaction, soil acidification, nutrient loss, agricultural product quality, a large amount of high yields of using fertilizer and pesticide and intensive cultivation to bring, have covered the abrupt degradation of soil quality.
The biomass solid wastes such as stalk and fowl and animal excrement are made to fertilizer by biological fermentation, they are returned in farmland, to address the above problem one of fundamental way, it is raw material that fertilizer be take the biomass solid wastes such as stalk, fowl and animal excrement conventionally, by microorganism, ferment and make, fertilizer improving soil organic matter content, improve aspect soil quality and there is important effect, yet, existing organic fertilizer production technique is mostly fairly simple, in production process, can discharge the foul smell such as ammonia, hydrogen sulfide, cause the loss of nitrogen and sulphur, simultaneously also can atmosphere pollution.In addition, the traffic requirements of stalk and fowl and animal excrement spends more cost, and the price of fertilizer itself is lower, and this has greatly hindered the universal of fertilizer and has applied.
By the biomass solid wastes such as stalk and fowl and animal excrement Pintsch process under limited oxygen condition, can obtain charcoal, also can obtain by product wood vinegar solution simultaneously.Charcoal is as renovation agent and the soil improvement agent of soil pollution in recent years, become numerous investigators' focus, charcoal is loose porous, there is larger specific surface area and stronger adsorptive power, can adsorb various heavy and organic pollutant, reduce the harm of heavy metal and organic pollutant, charcoal can improve the physico-chemical property of soil, improve the ability of Soil conservation nutrient and moisture, when significantly reducing chemical fertilizer amount of application, increase soil fertility, charcoal can improve quantity and the activity of soil microorganisms, also can promote growth and the activity of soil animal, thereby improve to persistence Soil structure, improve soil productivity.Yet when applying charcoal to soil, we should not ignore the fertility effect of organic matter or soil ulmin, in addition, charcoal is that a kind of quality is light, the fine particle materials of easily wafting, while using separately, easily cause charcoal with the form loss of dust, cause topsoil.
China's farmland quality is degenerated serious, and widespread pollution from the overuse of fertilizers and pesticides in rural area problem is day by day aggravated, improving soil quality and rehabilitating soil pollutes two work and must combine to carry out, just can play a multiplier effect, the preparation of fertilizer and charcoal is combined, making the fertilizer that contains charcoal, is to solve the good approach of this two hang-up.
Summary of the invention
The object of the invention is the technique for biomass solid waste fermentative production fertilizer by charcoal, and a kind of odorless fertilizer that contains charcoal and preparation method thereof is provided.Another object of the present invention is to reduce the generation of ammonia and hydrogen sulfide in organic fertilizer production process, reduces the loss of nitrogen and sulphur.Another object of the present invention is to reduce dust pollution and the Soil degradation problem producing while using charcoal separately.
For achieving the above object, the present invention adopts following technical scheme:
An odorless fertilizer that contains charcoal, organic content >=20%, charcoal content >=1%, moisture content is 7-14%, its preparation method is as follows:
(A) charcoal is immersed in wood vinegar solution more than 0.5h to the reodorant that to obtain take charcoal be carrier, described charcoal diameter≤16mm, specific surface area>=100m
2/ g, the massfraction of described wood vinegar solution is 0.2-15%, is the by product obtaining in charcoal preparation process;
(B) reodorant is joined in composting material, after adding amount of water, carry out fermented manure, described composting material is leaf or stalk and fowl and animal excrement, wherein the massfraction of leaf or stalk is 10-90%, surplus is fowl and animal excrement, add the mode of reodorant to be: by the 0.5-5% reodorant landfill of composting material quality below composting material, 0.5-5% reodorant and the composting material of composting material quality fully mix, and the 0.5-5% reodorant of composting material quality covers the surface of composting material in addition;
(C) after compost reaches the stage of becoming thoroughly decomposed, mixed fertilizer is dried, the odorless fertilizer that contains charcoal is made in granulation.
The present invention has following beneficial effect:
The present invention is applied in charcoal in the production and use procedure of fertilizer effectively, has both been conducive to composting process and has carried out fast and efficiently, can significantly improve again the result of use of charcoal and fertilizer; On the one hand, in composting material, add charcoal, be conducive to keep compost temperature, promote microbial growth, thereby improve composting efficiency, and charcoal can effectively absorb ammonia and hydrogen sulfide, the loss of nitrogen and sulphur in minimizing composting process; The dust pollution having produced while on the other hand, having reduced independent use charcoal; The fertilizer making contains abundant organic matter and charcoal, when significantly improving soil organic matter content, can effectively improve Soil structure, improves the ability of Soil conservation moisture and nutrient.
