The accumulation of top biomass, through original place also field decomposition, green manuring plant, so circulation, can rapidly lift mud-flat soil again
Organic matter it is circulating from cumulative process, so as to realize the quick improvement of mud-flat soil under low input, ploughed to increase China's agricultural
Ground reserved resources provide guarantee.
Other specific advantages of the invention and effect will go on to say below.
Brief description of the drawings
Fig. 1 --- schematic flow sheet of the present invention.
Specific embodiment
As shown in Figure 1：
1. selection of activated sludge
The domestic sludge that agricultural standards will be met is processed, used as organic fertilizer resource.
The quality of the domestic sludge must meet Ministry of Construction's promulgation《Urban wastewater treatment firm sludge treatment-the betterment of land
Use shale》(GB/T 24600-2009) national standard.Fresh Life sludge, the quick lime that can add its butt quality 1% is carried out
Harmless treatment.The domestic sludge that will be handled well is applied to mud-flat soil with ton/mu of butt 10, using rotary cultivator by sludge and 0
~20cm topsoil soils are mixed thoroughly.
2. mud-flat soil is applied
During domestic sludge after treatment imposed on into mud-flat soil, original fertility is formed.
3. green manure plant
Green manuring plant, then goes back field, and decomposition forms fertilizer.
In this process, carried out according to five seasons：
The 3-1. first seasons plant rye grass
The First Year 10-11 months, begin sowing in good time, Second Year May harvest, cut up with a hay cutter it is broken, also field；
The 3-2. second seasons plant the field mountain valley with clumps of trees and bamboo
In Second Year June, begin sowing in good time, then September harvest, cut up with a hay cutter it is broken, also field；
The 3-3. third quarters plant rye grass
The Second Year 10-11 months, begin sowing in good time, in May, the 3rd harvest, cut up with a hay cutter it is broken, also field；
The 3-4. fourth seasons plant the field mountain valley with clumps of trees and bamboo
In June, the 3rd, begin sowing in good time, then September harvest, cut up with a hay cutter it is broken, also field；
The seasons of 3-5. the 5th plant rye grass
The 3rd year 10-11 month, begin sowing in good time, in May, the 4th harvest, cut up with a hay cutter it is broken, also field.
So mud-flat soil is progressively cured after circulation, so as to reach the raising content of organic matter, improves soil texture, reduces salt
Divide content and lifting soil fertility.
Field management
(1) thickness of sowing：Improvement initial stage, mud-flat soil fertility is limited, and green manure thickness of sowing is easily small；With pushing away for improvement process
Enter, progressively properly increase thickness of sowing.Such as Planting Crops corn.
(2) field technology is gone back：For rapid the circulating of lifting mud-flat soil organic matter accumulates certainly, need to make by per season green manure
Thing carries out respective handling and carries out also field again.Major measure includes, when green manure crop is ripe, is gone back after green manure overground part is smashed
Field, and mixed thoroughly green manure with 0~20cm topsoil soils using rotary cultivator.
Without other special field management measures.
The present invention using domestic sludge as " original fertility carminative " carried out on beach five season green manure continuously plant
The also field test of field (rye grass, sesbania, rye grass, corn, rye grass).As a result, it was confirmed that domestic sludge is removed itself has an increased
Outside the soil organism, as " original fertility carminative ", can also by promoting continuing to build up for green manure plant shoot biomass,
Accelerate accumulating certainly for the soil organism eventually through also field mode.Before first season green manure (rye grass) also field, life is not applied
The control soil organic matter content of sludge is 3.84g kg-1, it is 13.85g kg that mu applies 10 tons for the treatment of of sludge-1；But the 4th
Before Ji Lvfei (corn) also fields, the former content of organic matter is 5.45g kg-1, and the latter has reached 29.78g kg-1.It can be seen that life is dirty
Mud is fairly obvious from the effect for accumulating as the soil organism caused by " original fertility carminative ".
During application domestic sludge is as " original fertility carminative " improvement mud-flat soil, made by sludge and green manure
Into the soil organism a large amount of accumulation may to soil physical and chemical property include organic matter, pH, salinity, CEC, oxidation-reduction potential
Etc. being changed, perhaps they can influence the metamorphosis of mud-flat soil heavy metal, and then influence the environmental safety of heavy metal.
The present invention has carried out the research work of a large amount of different sludge amounts of application.Result shows that butt sludge consumption is 150
Under conditions of ton/hectare, the weight in plant will not be made in general using the domestic sludge for meeting national agricultural standards
Metal is exceeded.Simultaneously experiment it has also been found that, using domestic sludge increased mud-flat soil plantation rye grass, milpa to Ni,
The absorption of Cu, Cd, Cr, Zn and Mn.With the increase of sludge amount of application, rye grass, corn overground part Ni, Cu, Cd, Cr and Zn concentration
In trend is gradually increasing, Mn is without significant changes；Rye grass, maize root system Cd, Cr and Zn concentration are in be gradually increasing trend, Ni, Cu
With Mn in downward trend after first rising.Using domestic sludge so that rye grass, the accumulation of corn Ni, Cu, Cd, Cr, Zn and Mn metal
Amount is in be gradually increasing trend with the increase of sludge amount of application.Correlation analysis show, Ni in rye grass, Corn, Cu, Cd,
The cumulant and sludge amount of application significant positive correlation of Cr, Zn and Mn.The domestic sludge of agricultural standards as beach will be met
The new technology low, speed of input for applying " original fertility carminative " improvement mud-flat soil of soil is fast, environment-friendly.
When domestic sludge is applied to mud-flat soil with " original fertility carminative ", make originally the almost beach without fertility
Soil possesses the original fertility of growth green manure plant, but improves the initial stage, and although mud-flat soil possesses the original of growth green manure plant
Beginning fertility, but salt content is still higher, is unfavorable for the growth of general crop.Therefore the selection of green manure plant and plantation are to beach
The follow-up circulation of organic matter formula of soil plays vital effect from cumulative process.
The present invention is verified by lot of experiments, when sludge is applied to mud-flat soil with " original fertility carminative ", to make
Downpayment green manure crop can grow under the conditions of hypersaline environment, first season green manure Plant choosing salt-tolerant plant rye grass, the second season
Green manure plant is the field mountain valley with clumps of trees and bamboo, the third quarter green manure plant be rye grass, fourth season green manure plant is the field mountain valley with clumps of trees and bamboo, the 5th season green manure plant for black
Wheat straw.Smashed by first five green manure plant, also field, rotary cultivator mixing, after decomposition, mud-flat soil salinity is significantly reduced, soil in season
Fertility is lifted steadily.6th season just can maize planting crop, implement in this manner, can reach the circulating of mud-flat soil organic matter
From accumulation purpose.
The effective technical bottleneck for solving the quick improvement under the conditions of the low input of mud-flat soil, Environmental security of the invention：
On the premise of total total metal content is controlled, the domestic sludge for meeting agricultural standards by one-time use is used as " original fertility drive
Dynamic agent " so that mud-flat soil possesses the original fertility of growth green manure plant, excites the accumulation of green manure plant shoot biomass,
Through original place also field decomposition, green manuring plant, so circulation again can rapidly lift the circulating from product of mud-flat soil organic matter
Tired process.So as to realize low input, fast speed, environment-friendly improvement mud-flat soil, to increase China's agriculture plantation standby money
Source provides guarantee.
Other indices of the invention：(1) the mud-flat soil content of organic matter is dramatically increased.Mu applies 10 tons for the treatment of of sludge
Mud-flat soil, before fourth season green manure (corn) also field, the content of organic matter has risen to 29.78g kg-1, increase than control
446.4%.(2) mud-flat soil salt content is significantly reduced.Mu applies 10 tons for the treatment of of sludge, when first season rye grass harvests, soil
Earth salt content reduces 71.0% than control.(3) mud-flat soil nitrogen, phosphorus nutrient are dramatically increased.Mu applies 10 tons of soil of sludge
The full N of earth, full P increase by 495.5%, 34.4% than control soil respectively.(4) mud-flat soil cation exchange capacity (CEC) (CEC) significantly increases
Plus.The soil CEC that mu applies 10 tons of sludge increased 22.5% than control.(5) recycling of domestic sludge is effectively realized.
Domestic sludge is the discarded object in sewage disposal process, and domestic sludge reasonably is used into mud-flat soil as organic fertilizer resource changes
