With addition of the biological-reinforced carbon conditioning agent, which is prepared from the mixed carbon agent and the fast-decomposing inocula, to soil, secondary salinized of the soil can be effectively alleviated. The invention provides a new economical, environmental-friendly, simple and convenient technology of treating the secondary salinized of the soil.
Description
Technical field
Patent of the present invention belongs to agricultural pollution soil remediation technical field, can be used for the improvement of secondary salinization soil etc.
Background technology
Along with the adjustment of the structure of rural undertaking, China's Installation Vegetable Cultivation area is from 0.53 ten thousand hm of 1978
2develop into more than 400 ten thousand hm of 2011
2.The in the situation that of high investment high production, within 3 years, left and right soil there will be secondary salinization in various degree, causes crop yield and quality to reduce.Although forefathers have proposed the approach of multiple solution green house of vegetables soil secondary salinization, as the waterflooding desalinization of soil by flooding or leaching, biological desalination, crop rotation, deep ploughing and soil moved in to improve the original, use biological organic fertilizer etc.These measures, in alleviating soil secondary salinization problem, exist application cost high, and range of application has prerequisite restriction, and the problem such as secondary environmental pollution.
The secondary salinization of industrialized agriculture soil is mainly the accumulation in table soil of the nitrate that too much causes due to nitrogen application.Make mutually principle according to the leading carbon nitrogen of microorganism known, the accumulation of nitrate radical is to receive this inorganic nitrogen-sourced owing to lacking suitable carbon source.Under suitable carbon source condition, inorganic nitrogen assimilation is transformed into organic nitrogen by microorganism.This process both can reduce the nitrate radical content in the soil solution, simultaneously also can be by increasing soil organic matter content, and the cation exchange capacity of soil is increased, reduce the amount that salinity enters the soil solution, poison thereby reduce salt.Kind, volume and the proportioning remarkably influenced thereof of carbon source its in soil decomposition speed and persistence remarkable, then impact transforms the effect of the nitrate radical in the soil solution, decomposition speed and the persistence of therefore, screening suitable carbon source formula, Reasonable Regulation And Control carbon source become important problem in science.
Summary of the invention
In order to solve the secondary salinization problem of soil, the invention provides a kind of biological reinforced carbon conditioning agent and utilize this conditioning agent to reduce the method for secondary salinization soil soluble salt content.The present invention, by add the biological reinforced carbon conditioning agent of preparing by mixing carbon agent and quick puterfaction bacteria agent in soil, is effectively alleviated soil secondary salinization.The new technology of an economy, environmental protection, easy improvement soil secondary salinization has been proposed.
Biological reinforced carbon conditioning agent of the present invention forms by mixing carbon agent and quick puterfaction bacteria agent, contains 0.3～1.0kg quick puterfaction bacteria agent in biological reinforced carbon conditioning agent per ton.
The agent of described mixing carbon is made up of according to following volume ratio following particle; Rice straw particle: corn stalk pellets: wheat stalk particle: rice husk particle: cotton stalk particle=5～10:0～5:5～10:0～5:1～3.
The agent of described mixing carbon can be prepared by following method: adopt dry wheat stalk, rice straw, maize straw, rice husk, cotton stalks etc. are pulverized for raw material, and the particle after pulverizing is the mixing carbon agent being prepared into according to certain volume after than (rice straw: maize straw: wheat stalk: rice husk: cotton stalk=5～10:0～5:5～10:0～5:1～3) even mixing.Decomposition conversion rate and the degree of granular size meeting remarkably influenced mixing carbon agent in soil, then affect the effect that biological reinforced carbon conditioning agent reduces secondary salinization soil soluble salt content, rice straw and corn stalk powder are broken into the particle of 2～5mm, wheat stalk and powdered rice hulls are broken into 1～3mm particle, and cotton stalk is ground into the particle of 5～10mm.The usage ratio of various stalks can comprehensively be determined according to soil property, temperature, soil secondary salinization degree etc.
Described biological reinforced carbon conditioning agent is prepared from by mixing carbon agent and quick puterfaction bacteria agent.Quick puterfaction bacteria agent is that the commercial fibre element of the general quick decomposition stalk carbon in market decomposes microbial preparation.Biological reinforced carbon conditioning agent evenly mixes by mixing carbon agent and quick puterfaction bacteria agent, contains the quick puterfaction bacteria agent of 0.3～1.0kg in biological reinforced carbon conditioning agent per ton.
The invention also discloses the using method of described biological reinforced carbon conditioning agent,
First, the biological reinforced carbon conditioning agent preparing evenly spreads fertilizer over the fields in the soil surface that secondary salinization occurs, and amount of application is 2～5 tons/mu.Biological reinforced carbon conditioning agent is deposited the obviously biological activity of reduction functional microorganism of duration, then affects its result of use, therefore need in 0～48 hour, use; Then, with rotary cultivator, topsoil soils dark 0～20cm is evenly turned over once; The 3rd, regulating Topsoil Water content is 25～35%; The 4th, according to soil property and temperature condition, normal temperature is cultivated 7～15 days, can significantly reduce secondary salinization soil soluble salt content occurs.
Beneficial effect
Add biological reinforced carbon conditioning agent can obviously reduce the concentration of nitrate radical in the soil solution, within the specific limits, reduction amplitude increases with the increase of carbon conditioning agent add-on.Under experiment condition, can in original concentration, reduce by 97.86% at most.Meanwhile, add carbon conditioning agent can significantly increase the content of Soil Available potassium.
Brief description of the drawings
Fig. 1 is the preparation of biological reinforced carbon conditioning agent and utilizes it to reduce the technological line of secondary salinization soil soluble salt content method.
Embodiment
Embodiment 1: biological reinforced carbon conditioning agent is for reducing the serious soil soluble salts contg of secondary salinization (soluble salt content >10g/kg, little green vegetables test is not emerged)
After various stalks are dried, are pulverized, after evenly mixing according to certain volume proportioning (rice straw: maize straw: wheat stalk: rice husk: cotton stalk=5:0:5:0:1), obtain mixing carbon agent; Mix carbon add agent and quick puterfaction bacteria agent (organic matter decomposing inoculant that Nanjing Ning Liang biotechnology company limited produces, living bacteria count >=0.5 hundred million/gram, addition is 1.0kg/ ton) obtain biological reinforced carbon conditioning agent after evenly mixing; The biological reinforced carbon conditioning agent preparing immediately (48 hours) evenly spreads fertilizer over the fields in the soil surface that secondary salinization occurs, and amount of application is 5 tons/mu; Topsoil soils dark 0～20cm is evenly turned over once with rotary cultivator; Regulating Topsoil Water content is 30%; Normal temperature is cultivated 15 days (Fig. 1).Before and after processing, soil soluble salts contg and composition are in table 1.As shown in Table 1, biological reinforced carbon conditioning agent significantly makes the specific conductivity that secondary salinization soil occurs decline 25.61%, and nitrate ion has declined 95.93%; Total salt content has reduced by 32.96%.Early-stage Study shows, nitrate radical is that in negatively charged ion, content is the highest, accounts for 60% left and right of whole negatively charged ion total amount, and therefore significantly declining of nitric acid root is the major cause that causes whole negatively charged ion total amount to decline.
