Description
Technical field
The present invention relates to a kind of method that alkaline earth soil is administered based on Pig raising wastewater, belong to alkaline earth Treatment process field.
Background technology
In recent years, the livestock and poultry breeding industry in China is quickly grown, and obvious ascendant trend is presented in livestock and poultry cultivation amount, so livestock and poultry
The wastewater discharge of plant is also increasing year by year, and Wastewater from Pig Farm is wherein accounting example larger portion.Large-scale pig farm
Waste water displacement it is big and concentrate, these waste water have that content of organics is high, Different Nitrogen Concentration is high, has antibiotic and pathogen residual
The features such as, it is necessary to be effectively treated before discharging, serious environmental pollution otherwise can be caused to environment, or even threaten local
Ecological safety.So Pig raising wastewater is concentrated and effectively handles and is very important.
Substantial amounts of alkaline earth earth be present in China.Soil containing basic salts such as more sodium carbonate and sodium acid carbonate in alkaline earth,
Soil is in strong basicity, the soil based on sodium colloid, and grogs disperses, and permeability is poor, hardened when doing, muddy when wet, soil physical chemistry
Character is poor, and the content of organic matter is low, and the anions and canons being harmful to plant growth are more, unfavorable to plant growth.These soil are not only not
Crop can be made to grow very well, some is also to the toxic effect of crop, and What is more, some alkaline earths not even a blade of grass grows, lie waste all the year round,
It greatly affected agricultural production and the ecological environment in China.Influenceed by many factors, domestic and international alkali soil erosion is also now
Constantly expanding, transforming the problem soils of such large area, be always the huge challenge that China agriculturist faces.It is existing
Alkali soil improvement agent mainly has several：Gypsum, organic fertilizer, sulphur, ardealite, calcium sulfite etc., these modifying agent improved effects are not
Substantially, the improved effect duration is shorter；Meanwhile alkaline earth is in addition to the characteristic of highly basic, it there is typically further that structure is hardened, organic matter
The characteristics of low with nutrient content, therefore the soil after its improvement is only capable of meeting that Activities of Some Plants grows in short term, is more unable to reach green
Change country or the provincial standard of planting soil.So, it would be highly desirable to find that a kind of improved effect is good, and improved effect is lasting, and can make
Soil after improvement reaches the alkali soil improvement method of planting technique Soil standard.
The content of the invention
The technical problems to be solved by the invention：Bad for existing alkali soil improvement agent improved effect, improved effect is held
The problem of continuous time is short, and the soil after improvement is unable to reach planting technique Soil standard, there is provided one kind is controlled based on Pig raising wastewater
The method for managing alkaline earth soil.
In order to solve the above technical problems, the technical solution adopted by the present invention is：
（1）Pig raising wastewater is taken to be filtered, collection filtered fluid, in mass ratio 2:3, wheat stalk and filtered fluid are put into fermentation vat
It is interior, pond is sealed by fermentation, sets fermentation vat temperature as 25~28 DEG C, with 130r/min stirrings fermentation 3~5 days, then raises temperature extremely
32~36 DEG C, ferment 4~6 days；
（2）After fermentation ends, the sealing of fermentation vat is removed, gravity-flow ventilation 1~2 day, fermenting mixture in fermentation vat is carried out
Filtering, zymotic fluid is collected, then by after fermentation residue natural drying 3~5 days, is put into pulverizer and is crushed, cross 150 mesh sieves,
Sieving particle is collected, obtains modified particles；
（3）Alkaline earth is plowed using turnplow, depth of plowing is 30~40cm, 7~9h of natural drying, modified particles is put into
In ditch dug with a plow, the amount of being put into is every mu of 40~45kg, reuses zymotic fluid and is sprayed in ditch dug with a plow, and fountain height is every mu of 1000~1800L；
（4）After the completion of zymotic fluid sprinkling, turned over using turnplow, then soil is carried out smooth, leveling land 3~5
After it, dug on leveling land and make wide 6~9cm, a height of 7~10cm irrigation canals and ditches, each two irrigation canals and ditches spacing is 45~55cm；
（5）Ecological bar is inserted in trench bottom, insertion depth of soil is 30~40cm, the spacing of the ecological bar in irrigation canals and ditches is 15~
20cm, then using step（2）In zymotic fluid fill each irrigation canals and ditches, use rice straw covering with irrigation canals and ditches alkaline earth soil
Ground, cladding thickness are 3~5cm, are covered 15~20 days；
（6）In overwrite procedure, every 3~5 days, step is sprayed to rice straw surface（2）In zymotic fluid, fountain height be every mu
900~1200L, after covering terminates, rice straw is removed, ecological bar is pulled out, irrigation canals and ditches is filled and led up, you can complete controlling for alkaline earth soil
Reason.
The preparation method of the ecological bar is：
（1）A length of 0.9~1.3m reed rods are taken, gets through inside reed rod, penetrates reed rod, the reed rod after insertion is soaked
In mass fraction is 3% hydrochloric acid, soaks 1~3 day, then take out the reed rod after insertion, natural drying 3~5 days, collect
Dry reed rod；
（2）Reed rod will be dried to be put into retort, design temperature is 200~230 DEG C, is incubated 1~2h, then it is warming up to 420~
480 DEG C, insulation 2~4h of charing, collect charing reed rod, you can obtain ecological bar.
Compared with other method, advantageous effects are the present invention：
（1）The present invention carries out fermentation process using the nutrients enriched in Pig raising wastewater to wheat stalk, obtains high hole, biology
The zymotic fluid that the high modified particles of activity and small molecule nutrients and enzyme enrich, micro- life is carried out to alkaline earth soil by zymotic fluid
Thing is modified, and soil inside is adjusted, and have additional nutrients thing, improves fertilizer efficiency, reuses the permeability that modified particles improve soil,
Adsorpting anion or cation, and then effective improvement alkaline earth soil；
（2）The present invention solves the problems, such as hardenedization of alkaline earth soil, improves organic matter and nutrient in soil, has wide
Application prospect.
