Description
Technical field
The invention belongs to agricultural technology field, be specifically related to a kind of salt-soda soil biological modification method.
Background technology
The improvement in salt-soda soil is the difficult problem in domestic and international agrology field.Although traditional ameliorative measure is a lot, but the most thorough
The end.The method and measures such as the most domestic modification method to salt-soda soil mainly has big hydraulic pressure alkali, the desalinization of soil by flooding or leaching, rice cultivation.Although passing through
It is preferable that the water resources industry such as Drainage of salt, the saturating drainage belt of irrigation and drainage by well wash soil salt effect thoroughly, but need good fresh water and supply
Answering condition, and invest big, economic benefit is low.
Summary of the invention
The present invention utilizes Modern microbiological technology, fermentation technique and traditional alkaline land improving technology to combine, it is achieved to salt
The comprehensive improvement on alkali ground.The invention provides and a kind of be applicable to all kinds of saline and alkaline, the Radix Rehmanniae, viscous weight, the reparation of the soil that hardens and improvement
Method, is also suitably for the arable farming of heavy-metal contaminated soil, reduces and reduces Heavy Metal Pollution.
The concrete technical scheme of the present invention is as follows:
A kind of salt-soda soil biological modification method, is combined with ground mulching realization by biological modification agent, this biological modification agent
Concrete preparation method as follows:
(1) microbial bacterial agent is made: take following raw material by weight: soybean meal 25-30 part, Testa oryzae 30-35 part, fish flour 8-

Yikang organic agriculture Technology Park, Yihe River company limited) 1 part, 0.1 part of carbamide, water 23-35 part, then above-mentioned material is sufficiently stirred for,
It is loaded in airtight container, carries out the anaerobic fermentation process of routine；Wherein anaerobic fermentation process is 25-27 DEG C of bar in temperature
Under part, anaerobic fermentation process continues 15-20 days, and pH value is stable about 3.5, completes anaerobic fermentation；
(2), after mixing with 2:1 with Semen Tritici aestivi and Semen Maydis mass ratio, regulation water content, to 25%, accesses aerobic fermentation bacterium
Plant (bacterial strain deposit number: CICC 10002), enter conventional aerobic fermentation process so that it is carry out aerobic fermentation；Little through 24-72
Time, mycelia occurs in a large number, and when surface is covered with mycelia, aerobic fermentation terminates；
(3) above-mentioned steps 1 product is mixed with the mass ratio of 2:1 with step 2 product, above two material mixing
After, regulation water content, to 30-35%, then puts into accumbency roller Zymolysis Equipment above-mentioned material；Keeping the outer temperature of tank is 20-
The natural temperature of 35 degree, can roll stirring once every 5 hours, each 15 minutes, carries out conventional ventilation oxygenation simultaneously；This step
In rapid, the process of aerobic fermentation is the process slowly dried simultaneously, treats that feed moisture content is down to 16%, biological modification agent fermentation system
Complete.
EM strain of the present invention is profit Kang Yuan EM stock solution, has purchased from Yikang organic agriculture Technology Park, Sino-Japan joint Linyi
Limit company；EM strain is a kind of composite flora, containing 120 antibacterials and 40 funguses, but is main to have following four classes: lactic acid
Mushroom (Lactobacillus plantarum, Lactobacillus casei), budding fungus (Saccharomyces
Cerevisiae), anaerobic type actinomycetes (Streptococcus spp.) and photosynthetic bacteria (Rhodopseudomonas
palustris)；
Carbamide of the present invention is conventional existing urea；
Aerobic fermentation strain of the present invention is obtained by regular channel, bacterial strain deposit number: CICC 10002.
Described salt-soda soil biological modification method, specifically comprises the following steps that
First Year, for convenience of operation, marks off 50 centimetres of wide A bands and 150 centimetres of wide B bands in field.
A band is according to the usage amount uniform broadcasting commercially available ordinary student organic fertilizer of 5000kg/ mu, simultaneously according to 100kg/ mu
Usage amount uniformly spreads fertilizer over the fields microorganism modifying agent, and on A band, plantation salt tolerant resists cold drought-enduring herbage simultaneously, and the kind of herbage does not limits.
Also according to the usage amount uniform broadcasting commercially available ordinary student organic fertilizer of 5000kg/ mu on B band, simultaneously according to
100kg/ mu usage amount uniformly spreads fertilizer over the fields microorganism modifying agent, and B band bedding thickness above is the straw of 10cm simultaneously, and straw profit makes
With commercially available common straw decomposing inoculant, prevent it from being blown off by wind with iron wire is fixing.
Second Year, pushes the straw in the middle of B band open to both sides, spills 50 centimetres of wide B2 bands, according to making of 2000kg/ mu
Consumption uniform broadcasting commercially available ordinary student organic fertilizer；Uniformly spread fertilizer over the fields microorganism modifying agent according to the usage amount of 100kg/ mu simultaneously,
Plant with A with the same herbage variety simultaneously.
3rd year, the straw that B1 and B3 on B2 band both sides is carried shallow plowing entered soil, according to the usage amount of 1000kg/ mu,
Use commercially available ordinary student organic fertilizer, uniformly spread fertilizer over the fields microorganism modifying agent according to the usage amount of 50kg/ mu, carry at B1, B3 simultaneously
The herbage that upper plantation is same.
The lawn so grown green and fresh exactly on the time of 3 years, whole salt-soda soil.
4th year, ditch in lawn, use common commercially available biological organic fertilizer according to the usage amount of 1000kg/ mu, according to
The usage amount of 50kg/ mu uses microorganism modifying agent, the crop of plantation Salt And Alkali Tolerance, retains banding lawn belt, cuts the turfgrass cut
The soil exposed below for nurse crop, it is ensured that lose earth.
The present invention relates to the making of microorganism modifying agent, and it operates with mode, for the comprehensive improvement in salt-soda soil.
By a series of comprehensive means, improve the physicochemical property (for details see attached table) in salt-soda soil, improve trees, nursery stock, agriculture in salt-soda soil
The survival rate of crop and growth potential, really realize the comprehensive utilization in salt-soda soil.
Biological modification is combined by this invention with ground mulching, and biological modification can improve soil physical property, increases
Soil aggregate, so that loosing soil, minimizing is hardened, beneficially water conservation, fertilizer conservation ventilation and promote root system development, for crop
Comfortable growing environment is provided.Evaporation can be reduced in ground mulching (straw, mulch film, non-woven fabrics, grass class) and plantation greenbelt,
Salinity in control saline groundwater is to earth's surface transporting, and improved effect is preferable.
The feature of the microbial bacterial agent in improvement salt-soda soil is: can coordinate straw, and the use of bio-fertilizer can reach good taking off
Salt effect.This microorganism modifying agent energy sweetening of the soil is saline and alkaline, reduces soil salt, and the most also phosphorus decomposing, potassium decomposing, fixed nitrogen etc. are many
Plant effect, thus activate other microorganism of soil, increase soil nutrient and the kind of microorganism, promote non-available nutrient in soil
Validation.We replace common fertilizer to be used for saline-alkali soil, at multiple-microorganism with the fertilizer adding this active microorganism
Effect under (humification, mineralising), improve salt affected soil ecological environment, reduce P in soil H-number and salinity, increase soil
Organic content, reaches finally to improve the purpose of saline-alkali soil.
