Description
Technical field
The present invention relates to a kind of method preparing soil conditioner, be specifically related to a kind of method utilizing poultry feather to prepare soil conditioner.
Background technology
In agriculture production, due to long-term a large amount of unreasonable use chemical fertilizer China's nearly decades, light organic fertilizer and industrial gas emission cause the farmland quality of China to be degenerated, have the dyskinetic soil that more than the 1000000000 mu of soil acidification in various degree of ploughing, salinification, the soil that hardens are more and more serious, it has a strong impact on plant growth, and output declines year by year, quality worse and worse, have a strong impact on our grain security, therefore, it is extremely urgent that transformation soil improves farmland quality.
Up to now, both at home and abroad the experience of salting of soil, acidifying ameliorative measure accumulation is comprised: control sulfur dioxide emissions, agricultural and biological modification measure, chemical modifying measure etc.
The method controlling sulfur dioxide emissions can not solve has degenerated and the soil compaction caused by other factors, acidifying, salinification problem; In chemical modifying, main employing neutralizes as lime carries out adding alkali, but repeatedly use can produce multiple acidization; And adopt sulphur gypsum, phosphogypsum, flyash, alkaline residue, ground phosphate rock etc. to carry out soil improvement, not only consumption is large, and the large-scale production and application of agricultural causes soil salt content increase to cause secondary salinization soil to increase the weight of, slag also likely causes secondary pollution containing harmful element to soil.
CN101665699B discloses a kind of nutrient conditioner for acidified soil in orchards and preparation method thereof and application, carbon CaCl2, light burnt powder, flyash, slag, common fused(calcium magnesium phosphorus)potash fertilizer etc. are contained for mainly to improve composition in this soil improvement agent, these alkaline matter compositions can neutralizing acid basicity, its shortcoming is that consumption is large, life-time service can cause the soil salinization more and more seriously, can produce secondary harm etc.; CN100429290C discloses a kind of preparation method of saline-alkali soil conditioner, by after polyacrylic acid dilute with water, under agitation add mineral acid, wood vinegar and plant hormone successively to mix, this product belong to simple physical mixing, several raw material adopt be commercially available resource, Material Cost is high; CN102559197B discloses a kind of saline-alkali soil conditioner and preparation method thereof, is amino acid, urea, acetic acid, sodium nitrophenolate and water to be mixed, and what adopt equally is commercially available resource, and Material Cost is high.
Having used drake feather in Special basal fertilizer for peanut disclosed in CN102816025B, is that rear for drake feather hydrolysis and trace element are carried out chelating; CN102936168A discloses a kind of ecological nitrogen fertilizer and preparation method thereof, be animal hair, feather acid are hydrolyzed, chelating, then with plant filtrate mixing granulation.Technique scheme only have employed carries out proteolysis, single sour chelated microelement by feather/hair, there is the defect that action effect is single.
In sum, current this area has had multiple for soil improvement, kind modifying agent is repaiied in salinification, although have certain improved effect, still lacks cheap, quick, multiple-effect, environmental protection, does not produce secondary harm and the soil remediation amendment for the treatment of both principal and secondary aspect of disease.
Summary of the invention
Technical problem to be solved by this invention is, overcome the above-mentioned defect that prior art exists, there is provided one can realize waste resource comprehensive utilization, cost is low, it is simple, easy to use to prepare, Effect of improving soil is remarkable, to person poultry safety, friendly to crop edatope, do not produce secondary harm, the poultry feather that utilizes reaching target for the treatment of both principal and secondary aspect of disease prepares the method for soil conditioner.
The technical solution adopted for the present invention to solve the technical problems is as follows: a kind of method utilizing poultry feather to prepare soil conditioner, comprises the following steps:
