Description
Technical field
The present invention relates to a kind of Nutrition Soil and preparation method thereof, be specially a kind of organic nutrient soil and method thereof of utilizing the straw biogas residue preparation.
Background technology
Biogas is as the existing very long history of energy utilization.The biogas of China is mainly methane-generating pit for farm household at first, early 1970s, for solving the problem of crop straw burning and undercharge, the Chinese government promotes the biogas cause in the rural area, and the biogas that methane-generating pit produces develops into illumination and heating gradually by the cooking that is used for rural households.At present, household biogas still is being widely used in China rural area.The big-and-middle-sized biogas engineering of China starts from the fifties in last century, and after this, production and the use range of biogas have been widened in the foundation of big-and-middle-sized waste water, aquaculture sewage, villages and small towns biomass waste, municipal wastes biogas.Along with China's economy is sent out the development of the raising of living standards of the people and industry, agricultural, aquaculture, waste fermentation methane engineering will be the effective method of China's renewable energy utilization and protection.
Biogas fermentation comprehensive utilization, the material of having set up since the eighties utilizes at many levels, the high-efficiency agriculture Development patterns of energy Rational flow, becomes gradually the effective ways that rural areas in our country utilizes biogas technology to promote sustainable development.By the biogas fermentation comprehensive utilization technique, biogas is used for peasant household life energy and agricultural byproducts production, processing, natural pond liquid is used for feed, biological pesticide, cultivate the production of feed liquid, the natural pond slag is used for the production of fertilizer, the plastic greenhouse that northern China is promoted, methane-generating pit, fowl animal house and " quaternity " Biogas Eco-agricultural Mode that combines, the Ecological Orchard pattern take biogas as tie of middle area, " pig one fruit " pattern that south is set up, and other areas " the cultivating a methane-generating pit " of suiting measures to local conditions to set up, " pig one natural pond one fish " and " a careless Niu Yizhao " isotype all are as tie take biogas, to biogas, natural pond liquid, the ecological agricultural model of the multi-level utilization of natural pond slag, biogas fermentation comprehensive utilization ecological agricultural model is set up the production and use of marsh gas and Agro-ecology is combined closely, the effective measure of improving rural environmental hygiene, it is development green planting industry, the effective way of aquaculture has become the rural economy new growth point.
When utilizing biogas, can also fully utilize with biogas produced simultaneously natural pond slag and natural pond liquid.The natural pond slag is except containing abundant nitrogen, phosphorus, potassium and a large amount of element, also contain the various trace elements that plant growth is played an important role, be a kind of extraordinary fertilizer, the especially northern natural pond slag that produces take stalk as raw material contains abundant potassium element, can satisfy demand of plant growth.Tradition natural pond slag muck is macerated and is caused the fertilizer nutritive element to run off in a large number, and each element loss is large, and the action effect of natural pond slag is reduced, and the natural pond slag can not be directly used in again the plantation of crop simultaneously, must form Nutrition Soil by allotment and be used.Present existing Nutrition Soil mainly is that the chemical fertilizer, agricultural chemicals by inorganics etc. regulated nutritive element wherein, and crop is difficult for absorbing, and cost is large, and weak effect has reduced quality and the quality of agricultural-food.
Summary of the invention
The object of the invention is to the natural pond slag that produces take stalk as main raw material for the north, provide that a kind of can to solve the Nutrition Soil fertility poor, mineral manure content is high, and the fertilizer assimilation effect is bad, the problem that cost is high, organic nutrient soil and the method thereof of utilizing straw biogas residue to prepare.
In order to solve above-mentioned technical problem, the present invention adopts following technical scheme:
A kind of method of utilizing straw biogas residue to prepare organic nutrient soil, step is as follows:
A. the processing of natural pond slag, the natural pond slag that will discharge from methane-generating pit joins in the solid-liquid separating machine, and carrying out solid-liquid separation, to obtain water content be that the dehydration natural pond slag of 55%-65% is for subsequent use;
B. the fermentation that is mixed, the natural pond slag that will dewater, earth, wood chip, organic fertilizer, mineral manure mixing and stirring are sent in the fermentation vat that water-tight is processed and after normal temperature anaerobic fermentation 15-25 days, namely obtain utilizing the organic nutrient soil of straw biogas residue preparation.
Further, the natural pond slag described in the step a is the fermentation resistates of the raw material that is comprised of stalk and human and animal excreta.
Further, the weight percent of stalk and human and animal excreta is as follows in the described raw material: stalk 75%-85%, human and animal excreta 15%-25%.
Further, the natural pond slag described in the step a, its organic dry weight content is not less than 30%.
Further, the raw material that comprises following weight percent described in the step b: dehydration natural pond slag 20%-30%, earth 55%-70%, wood chip 5%-10%, organic fertilizer 1.5%-3%, mineral manure 1%-2.8%.
Further, the earth described in the step b is comprised of clay and sand, and the weight percent that accounts for respectively earth is: clay 70%-80%, sand 20%-30%.
Further, described clay is Mount Huang mud, and sand is river sand.
Further, the organic fertilizer described in the step b comprises bone meal and plant ash, and the weight percent that accounts for respectively Nutrition Soil is: bone meal 0.5%-1%, plant ash 1%-2%.
Further, the mineral manure described in the step b comprises ammonium sulfate, zinc sulfate, manganous sulfate and boric acid, and the weight percent that accounts for respectively Nutrition Soil is: ammonium sulfate 1%-2.5%, zinc sulfate 0.2%-0.4%, manganous sulfate 0.2%-0.4%, boric acid 0.1%-0.2%.
A kind of organic nutrient soil that utilizes the straw biogas residue preparation is to be prepared from organic nutrient soil by above-described method.
The contrast prior art, beneficial effect of the present invention is as follows:
1) promote plant growth, balanced in nutrition, output obviously improves; Take straw biogas residue as main, not only realized straw-returning, and be to go back after treatment the field, realized simultaneously taking full advantage of of natural pond slag, the utilising efficiency of fertilizer is high, need not again to use chemical fertilizer, prevented abusing of chemical fertilizer, the greatly lower content of nitrate in the farmland.
2) improved the quality of agricultural-food, for the production of organic farm products has improved facility; Take the natural pond slag on main basis, by organic fertilizer as main nutrition regulating agent, replenish by mineral manure again and add the trace element, make fully comprehensively Absorption of nourishment element of farm crop, stop simultaneously the objectionable impurities accumulation that a large amount of use mineral manure bring, reduced the murder by poisoning to farm crop.
3) applied range is made simple and conveniently, and cost is low; Directly the natural pond slag is made the form of Nutrition Soil, can be directly used in the cultivation of farm crop, flowers etc., can be widely used in the cultivation of seedling, the plantation of roof, garden flowers; Most of raw material owing to employing is discarded organism simultaneously, therefore greatly reduces cost, and making and use are all very convenient.
