Salt-soda soil afforestation improver special (Shandong sea day bio-fertilizer industry Co., Ltd).
Effect test
21 pieces of saline and alkaline experimental plots of saline and alkaline and area identical are chosen, it is one of as blank group, any tune is not applied
Reason agent or fertilizer, the salt affected soil for applying embodiment 1-12 and comparative example 1-8 respectively on other 20 pieces of saline and alkaline experimental plots are nursed one's health
Agent or salt-soda soil afforestation improver special carry out the betterment of land, and conditioner or modifying agent are uniformly sprinkled into soil 20-30cm
Depths, sowing amount is 1t/ mus, is then planted respectively on 21 pieces of experimental plots in equivalent corn, corn growing season and does not apply other
Fertilizer, the field management during experiment is managed collectively according to local Corn production management pattern.Result of the test is as shown in table 1.
The result of the test of table 1
Be can be seen that from the result of the test of table 1：
(1) after applying the saline alkali soil conditioner of embodiment 1-12, the pH value and Na in experimental plot+Content has been obtained significantly
Reduce, pH value highest can reduce by 14.8%, Na+Content highest can reduce by 61.1%, and be substantially better than comparative example 1-8, explanation
The saline alkali soil conditioner of embodiment 1-12 has given full play to the coordinated effect of each raw material, can adjust soil salt alkalescence,
Improved saline-alkali soil.
(2) embodiment 4-11 and the difference of embodiment 3 are respectively microbial bacterial agent, urease inhibitor or nitrification inhibitor
Selection it is different, wherein embodiment 4-11 has been respectively adopted preferred ingredient of the invention, can from the result of the test of above-described embodiment
Know, pH, the Na in the experimental plot that the saline alkali soil conditioner obtained with above-mentioned preferred ingredient is treated+Content, active nitrogen content, work
Property phosphorus content, the content of organic matter, field capacity and total metalses be superior to using not preferred component, and by improvement
The corn emergence rate and yield in experimental plot are higher.
In addition, the difference of embodiment 4 and 6,8,10 and embodiment 5 and 7,9,11 is only that each microbial bacterial agent, each respectively
The proportioning difference of urease inhibitor, each nitrification inhibitor, wherein embodiment 4 and 6,8,10 employs optimum ratio of the invention,
And embodiment 5 and 7,9,11 employs not preferred proportioning, knowable to the result of the test of embodiment 4-11, obtained with above-mentioned optimum ratio
PH, the Na in the experimental plot that the saline alkali soil conditioner for arriving is treated+Content, active nitrogen content, active phosphorus content and organic matter contain
Amount is superior to using not preferred proportioning, and it is higher to pass through the corn emergence rate and yield in the experimental plot of improvement.
Therefore, the present invention is provided microbial bacterial agent, the preferred ingredient of urease inhibitor and nitrification inhibitor and each micro-
The optimum ratio of bacteria agent, each urease inhibitor and each nitrification inhibitor has given full play to it and has matched somebody with somebody with cooperateing with for other each raw materials
Cooperation is used, and the saline alkali soil conditioner of gained is more preferable to the improved effect in salt-soda soil.
(3) after applying the saline alkali soil conditioner of embodiment 1-12, the active nitrogen content in experimental plot is held essentially constant, and says
The nitrogen fixation effect of bright embodiment 1-12 is good, can effective preservation of fertility, and apply the conditioner or modifying agent of comparative example 1-8
Afterwards, active nitrogen content reduction in soil, illustrates that the nitrogen fixation effect of comparative example 1-8 is poor, and soil fertility can be caused to reduce.
(4) after applying the saline alkali soil conditioner of embodiment 1-12, the active phosphorus content in experimental plot, the content of organic matter and field
Between water-holding capacity be improved significantly, illustrate embodiment 1-12 phosphorus decomposing effect, increase organic matter effect and Water-saving effect
It is good, soil fertility can be effectively increased, and ground moistening degree is kept, reduction is secondary to topdress, beneficial to plant growth；And apply contrast
The incrementss of active phosphorus content, the content of organic matter and field capacity are very after the conditioner or modifying agent of example 1-8, in soil
It is small, illustrate that phosphorus decomposing effect, the effect of increase organic matter and the Water-saving effect of comparative example 1-8 are poor, it is unfavorable for increasing soil fertilizer
Power and plant growth.
(5) after applying the conditioner or modifying agent of embodiment 1-12 and comparative example 1-8 respectively, the total metalses in soil
It is reduced, by contrast, the reduction amplitude of the total metalses of embodiment 1-12 is very big, highest reduction amplitude can
99.2% is reached, the release action of heavy metal is substantially better than comparative example 1-8, the salt affected soil conditioning of this explanation embodiment 1-12
Agent has given full play to the coordinated effect of each raw material, has effectively played carboxymethyl chitosan, polyacrylamide and starch counterweight
The suction-operated of metal, reduces heavy metal in soil content, reduces soil pollution.
(6) after the saline alkali soil conditioner that application of embodiment 1-12, the emergence rate of corn can reach more than 80%,
89.7% is reached as high as, the experimental plot than not doing any treatment is higher by 43.5%；Yield more than 400kg/ mus, is reached as high as
469kg/ mus, the experimental plot than not doing any treatment is higher by 115%；Thus illustrate, the saline alkali soil conditioner of embodiment 1-12
Improved effect to salt affected soil is obvious, increases by soil fertility after improvement, is conducive to growing for crop, grain yield
It is high.Comparative example 1-8 is reviewed, although its emergence rate and yield have also obtained a certain degree of raising, effect is not obvious, emerges
Rate and yield are poor compared with embodiment 1-12, illustrate that the saline alkali soil conditioner of embodiment 1-12 has given full play to each raw material
Mating reaction, can effective improved soil, improve soil microenvironment, regulation soil salinity and alkalinity, increase the content of organic matter,
Preservation of fertility, enables crop normal growth development on the soil after improvement, improves crop yield.
Except comparative example 2 and comparative example 8 raw material from it is of the invention it is different in addition to, although the raw material of remaining each comparative example and this
Invention is identical, but the content of each raw material and its mutually proportioning be not in content of the invention and ratio range, and its item refers to
Mark is inferior to embodiment 1-12, thus fully proves, the saline alkali soil conditioner that the present invention is provided has given full play to each raw material
Coordinated is acted on, and can effectively reduce the pH value and salt content of salt affected soil, mitigates soil hardening, increases calcium, iron in soil
And the content of organic matter, improve soil microenvironment, and fixed nitrogen phosphorus decomposing can be played a part of, preservation of fertility is reduced
Fertilising secondary is topdressed.
Although illustrate and describing the present invention with specific embodiment, but will be appreciated that without departing substantially from of the invention
