Abstract
The invention provides a charcoal fertilizer capable of soil heavy metal passivation and having high water-retention rate. The charcoal fertilizer comprises the following ingredients (by weight): 55-75 parts of charcoal, 15-30 parts of plant vinegar liquid, 6-15 parts of waste molasses, 0.05-0.5 part of probiotics and 2-6 parts of super absorbent resin. The charcoal fertilizer capable of soil heavy metal passivation and having high water-retention rate contains charcoal which has huge specific surface area and excellent adsorptive property and has high affinity for heavy metal elements. The charcoal fertilizer can be greatly combined with nutrients in soil, thus effectively reducing loss of nutrients. The charcoal fertilizer contains probiotics, thus maintaining soil fertility. The charcoal fertilizer contains waste molasses, and humic acid in waste molasses can promote crop growth and reduce toxicity of soil heavy metal. As the charcoal fertilizer contains super absorbent resin, the charcoal fertilizer has strong water absorbing capacity and water retention capacity, thus enhancing water retention property and fertilizer conservation property of soil.
Description
Technical field
The invention belongs to soil fertilizer field, be specifically related to one and can be passivated heavy metal-polluted soil and water retention height
Charcoal fertilizer.
Background technology
Along with the fast development of industry, current soil heavy metal pollution phenomenon has tended to universal.A huge sum of money in soil
Genus etc. can pass through " soil → plant → human body ", or by " soil → water → human body " indirectly by human body
Absorbing, damage healthy, therefore repairing heavy metal in soil pollutes and is increasingly paid attention to by expert.Most preferably
Soil remediation method be the ecological functions that can either keep soil, the fertility that soil is even provided can be kept,
Can effectively hinder again the pollutant such as control heavy metal and enter food chain.Accordingly, it would be desirable to a research and development one collection absorption huge sum of money
Belonging to and provide crop nutrient elements, being blended in the fertilising of agricultural production by heavy metal repair materials, this is real
The purpose that existing production limit, limit, heavy metal pollution arable land is repaired.
Charcoal refers to the biomass resource being widely present with nature, such as crop material and woods fruit tree branch
Deng, the carbonaceous material produced by thermal cracking under anoxic conditions.Charcoal is porous mass, has extremely
Abundant gap structure and huge specific surface area, absorption property is excellent, and charcoal is alkalescence, is difficult to by ring
Border microbial decomposition, therefore, charcoal can adsorb the heavy metal element in soil, can be passivated in soil
Heavy metal.
Super absorbent resin is to contain polar group in molecule and have certain degree of cross linking, by being chemically crosslinked
With being mutually wound around of polymer molecule interchain and produce the class new function macromolecule material that physical crosslinking is constituted
Material, can absorb rapidly the water of the most thousands of times of own wt hundred times, has powerful moisture holding capacity, and water suction
The most inflatable have holding immobilising state, even if apply pressure also will not seepage, there is release water simultaneously
Ability, have the suction of self to release the balance system of water, the most absorbed water can be gently greatly
Gas disengages.Owing to having above-mentioned characteristic, water-absorbing resin is used in the water-loss reducer of soil of agriculture and forestry the earliest.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of economical, stable, safe, at an absorption huge sum of money
Belong to and simultaneously the most also can provide nutrient and the high charcoal fertilizer of water retention to crops.
The present invention solves the technical scheme of above-mentioned technical problem, and one can be passivated heavy metal-polluted soil and water conservation
The charcoal fertilizer that rate is high, including each component of following parts by weight: charcoal 55-75 part, plant vinegar liquid 15-30
Part, blackstrap 6-15 part, probiotic bacteria 0.05-0.5 part, High hydrophilous resin 2-6 part.
Preferably, described charcoal is sequentially passed through dry in the sun by the filter mud in sugar refinery or the manioc waste of starch factory and processes
To moisture be 20%-35%, extruder grain and retort carbonization formed.
Preferably, described charcoal is by one or more materials in cotton stalk, Pepper stalk and tree root
Oxygen barrier is pyrolyzed and passes through grinding and sieves and prepare under nitrogen protection.
Preferably, total humic acid >=28% of described blackstrap, total nutrient >=8%, moisture≤60%.
Preferably, described probiotic bacteria is bacillus cereus or nitrogen-fixing bacteria.
Preferably, the temperature of described oxygen barrier pyrolysis is 400-600 DEG C, and the time is 5-8 hour.
Preferably, the living bacteria count of described probiotic bacteria is not less than 0.5 hundred million/gram.
Beneficial effects of the present invention: the present invention can be passivated heavy metal-polluted soil and the high charcoal fertilizer of water retention
Containing charcoal, charcoal has huge specific surface area, and absorption property is excellent, and heavy metal element has
Higher affinity, charcoal fertilizer preferably can be combined by the nutrient in soil, effectively reduce nutrient loss；
Charcoal fertilizer contains probiotics, can keep the fertility of soil；Containing blackstrap in charcoal, in blackstrap
Humic acids can promote plant growth, also reduces the toxicity of heavy metal-polluted soil, containing High hydrophilous resin, has very
Strong water absorbing capacity and water holding capacity, can improve water-retaining property and the nutrient preserving capability of soil.
