Description
Technical field
The present invention relates to a kind of saline-alkali land soil conditioner and preparation method thereof, particularly to a kind of multi-functional Lumbricus dung salt
Alkali land soil agent and preparation method thereof.
Background technology
Saline-alkali soil is salinization or a class soil of alkalization formation, and salt-soda soil surface soil is dried more, white, is even formed
Salt incrustation, be full of cracks of hardening, salinity is high, and corrosivity is strong, can destroy plant cell tissue, hinders plant growing, high salt basicity soil
Earth even can directly make root system of plant rot to cause plant dead.
In view of the present situation that China per capita cultivated land is few, alkaline land soil improving technology, the base that the mankind depend on for existence can be increased
Plinth material cultivated area, has profound significance to agro-farming.
Improvement currently for salt-soda soil typically uses acid neutralisation and water irrigation method, and acid neutralisation is by acid such as sulphuric acid
Liquid waters and is sprinkled upon on salt-soda soil, makes the pH value of soil tend to neutral, but soil can be caused to harden further；Water irrigation method needs a large amount of
Fresh water flush soil in saline and alkaline, but a lot of place does not has enough water sources.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of multi-functional wormcast saline-alkali land soil conditioner and preparation thereof
Method, severe physicochemical property and Soil structure to saline-alkali soil have good improved effect, reduce the salinity harmful to soil
And basicity, harmful Na+、CO3 -And HCO3 -Ion concentration and reduce P in soil H, increases the organic matter of soil, humus, useful
Flora, improves the porosity of soil, increases soil aggregate, soil ground pine, and saline-alkali soil is improved, and crop obtains volume increase,
Saline-alkali wasteland can gradually become farmland.
The technical scheme is that
A kind of multi-functional wormcast saline-alkali land soil conditioner, consists of the following composition according to weight/mass percentage composition:
Wormcast 50%～60%, furfural dregs 20%～25%, ardealite 20%～25%；
Described wormcast obtains with straw and mud for earthworm feedstuff.
Described straw is 1:10 with the mass ratio of mud.
The preparation method of a kind of multi-functional wormcast saline-alkali land soil conditioner, comprises the following steps:
(1) crushed stalk is become the granule of a length of 5mm～8mm；
(2) straw and mud are mixed and stirred for uniformly, obtaining earthworm feedstuff according to mass ratio 1:10；
(3) with described earthworm feedstuff feed Lumbricus, the earthworm breeding feed time is 45 days～60 days, treats the mud in earthworm feedstuff
Odorless and abnormal flavour also become soft crineous, and the most excellent mud wormcast just creates；
(4) after being separated with wormcast by Lumbricus, wormcast is carried out dry in the sun, make moisture≤30% in wormcast, by quality
Percentage composition is by wormcast 50%～60%, furfural dregs 20%～25%, and ardealite 20%～25% stirs, and obtains saline and alkaline
Soil modifying agent.
Described mud is the domestic sludge after sewage treatment plant processes.
Beneficial effects of the present invention:
(1) domestic sewage sludge after sewage treatment plant processes is added direct feeding earthworm after crushing straw stirs
Earthworm, the wormcast produced after the microbial association in Lumbricus and earthworm feedstuff digests, stir with furfural dregs and ardealite
The saline-alkali soil modifying agent of preparation, the various nutritional labelings needed rich in organic humus, plant and multiple beneficial microorganism
Flora, and containing activated calcium, and physicochemical property bad to saline-alkali soil and the multi-faceted improving effect of Soil structure in acidity.
(2) saline-alkali soil modifying agent has good improved effect, often to severe physicochemical property and the Soil structure of saline-alkali soil
Mu amount of application is 1000kg-1500kg, can reduce the salinity harmful to soil and basicity, harmful Na+、CO3 -And HCO3 -
Ion concentration and reduction P in soil H, increase the organic matter of soil, humus, profitable strain, improve the porosity of soil, increase soil
Earth crumb structure, soil ground is loose, and saline-alkali soil is improved, and crop obtains volume increase, and saline-alkali wasteland can gradually become farmland.
(3) several raw materials that saline-alkali soil modifying agent uses: straw, mud, furfural dregs, ardealite are the regeneration of garbage
Utilize, comprehensively utilized, both turned waste into wealth, solve again the atmosphere polluting problem brought because of crop straw burning, and mud etc.
Pollution problem to environment, therefore not only increases economic benefit, has bigger ecological benefits simultaneously.

Reference examples 1
Comparison field management: executing disposable depot fertilizer Bulk Blending Fertilizer 35 kilograms for every mu at seeding time, this depot fertilizer Bulk Blending Fertilizer total nutrient is
52%, wherein nitrogen content be 28%, phosphorus content be 12%, potassium content be 12%.During sowing, the sowing of corn seed is spaced apart 7
Centimetre～8 centimeters, deep placement base fertilizer.After planting with 81.5% Acetochlor (consumption is 200 grams/acre) and the atrazine (200 of 35%
Gram/acre) mixing of both herbicides sprays field medicament and close.Gather in the crops without after field management Semen Maydis maturation.
Salt-soda soil field experiment:
Carry out field experiment in the salt-soda soil of saline-alkali soil, experimental plot is divided into 4 pieces, wherein 4 pieces of experimental plots, with not administration of salt
Alkali soil improvement agent is reference examples 1.Other 3 pieces of experimental plots, before corn seeding, the most corresponding by the embodiment of the present invention 1 saline-alkali soil
1000kg/ mu used by modifying agent, embodiment 2 uses 1200kg/ mu, the saline-alkali soil modifying agent amount of application 1500kg/ of embodiment 3
Mu, and topsoil of turning over (in 20cm), other management is with to compare 1 identical.Soil sample is surveyed its pH value, HCO3 -、K++Na+、Ca2 +.Testing result is as follows:
Table 1 embodiment of the present invention 1～3 and the P in soil H-number of reference examples 1 and ion concentration
| Matched group 1 | Embodiment 1 | Embodiment 2 | Embodiment 3 | |
| PH | 9.8 | 8.5 | 8.0 | 7.5 |
| HCO<sub>3</sub><sup>-</sup>Mmol/100g soil | 0.4320 | 0.1685 | 0.1495 | 0.1230 |
| K<sup>+</sup>+Na<sup>+</sup>Mmol/100g soil | 0.9592 | 0.7180 | 0.5030 | 0.1120 |
| Ca<sup>2+</sup>Mmol/100g soil | 0.0515 | 1.7058 | 4.0080 | 7.9000 |
The saline-alkali soil pH value using saline-alkali soil modifying agent as can be drawn from Table 1 is decreased obviously, the HCO of damage to crops3 -And Na+The brightest
Aobvious decline, and useful Ca2+Substantially increase.
After using the saline-alkali soil modifying agent of the present invention, soil activation calcium Ca2 +Improve, the sodium carbonate of damage to crops maximum and weight
Carbonate content significantly reduces, and the basicity pH value of soil substantially reduces, and Soil exghangeable sodium ion and basicity reduce.Sodium colloid
Soil be converted into calcium colloid, soil and humic plastid soil, the bad physicochemical property of salt affected soil and murder by poisoning and improved, send out
Existing soil is soft, thus is also significantly improved the yield of crops.The application embodiment 1 of modifying agent, embodiment 2, enforcement
Ratio comparison 1 volume increase 15.5%, 26.8% respectively of example 3 corn yield, 31.5%.
These are only the specific embodiment of the present invention, be not limited to the present invention, for those skilled in the art
