Description
Technical field
The present invention relates to a kind of stable nitrification inhibitors and the preparation method and application thereof, belong to nitrogenous fertilizer Synergistic technique neck
Domain.
Background technique
In recent years, Chinese nitrogen fertilizer amount increases year by year, while Economic Benefit of Agricultural Production improves, is caused using nitrogenous fertilizer
Environmental problem it is of increasing concern.A large amount of nitrogens leave soil, into atmosphere and water body, cause atmosphere and water pollution, and
Reducing chemical fertilizer investment and improving the utilization rate of nitrogen is to alleviate the effective way of atmosphere and water pollution.Ammonium nitrogen is easily by soil glue
Body fixation is not easy to outflow with water, and nitrate nitrogen easily outflows with water, and the presence of nitrification accelerates what nitrate nitrogen outflowed with water
Probability, nitrification inhibitor can regulate and control the Transport And Transformation of soil nitrogen, extend the residence time of ammonium nitrogen in the soil, effectively subtract
The loss of few nitrogen and the utilization rate for improving nitrogen.
3,4- dimethyl pyrazole phosphate (DMPP) are a kind of efficient, safe and nontoxic and more cheap nitrification inhibitors,
Nitrification inhibitor DMPP is added in fertilizer, the activity of nitrosation, nitrifiers and denitrifiers can be inhibited in the soil, controls ammonium state
Nitrogen is converted to nitrate nitrogen, to realize that stablizing for nitrogen is supplied, is reduced the discharge of the leaching loss and nitrogen oxide of nitrate nitrogen, is mentioned with reaching
High chemical fertilizer utilization ratio, protection environment, the purpose for promoting agricultural development.But there are two for the DMPP nitrification inhibitor applied at present
Problem: first is that DMPP is to be formed by 3,4- dimethyl pyrazole and phosphatase reaction, and 3,4- dimethyl pyrazoles are highly volatiles,
So DMPP is relatively easy to volatilize, especially it is applied in basic soil, more volatile after phosphate and alkali neutralization, this is greatly limited
The application range and application effect of DMPP are made；Second is that can not be carried out in fertilizer process due to the effumability of DMPP
Interior addition, so DMPP mainly passes through trypsin method technical application to fertilizer surface, but trypsin method method needs solvent, be easy to cause
Fertilizer surface is moist, reduces fertilizer intensity, and the recycling of solvent will also increase technology difficulty.Chinese patent document
CN108017478A discloses a kind of poly- polyphenol cladding nitrification inhibitor and the preparation method and application thereof, the poly- polyphenol cladding
Nitrification inhibitor includes: the poly- polyphenol of nitrification inhibitor and cladding nitrification inhibitor.Preparation method is that polyphenol polymer exists
Nitrification inhibitor surface carries out polymerization reaction.But the preparation method is more complex.
Therefore the effumability for solving DMPP, is prepared into a kind of stable DMPP nitrification inhibitor, will greatly expand
Open up the application range and application effect of DMPP.

Processing 11: 40kg complex fertilizer product H1 and 20kg urea product H is as base manure applied once, no longer top dressing per acre.
Processing 12: 40kg complex fertilizer product I1 and 20kg urea product I is as base manure applied once, no longer top dressing per acre.
Experimental result is as shown in table 1:
Table 1
| Processing | Yield (kg/ mus) | Than 1 volume increase of processing | Than 2 volume increase of processing | Than 3 volume increase of processing |
| Processing 1 | 594 | ---- | ---- | ---- |
| Processing 2 | 512 | - 13.80% | ---- | ---- |
| Processing 3 | 603 | ---- | 17.77% | ---- |
| Processing 4 | 631 | ---- | ---- | 4.64% |
| Processing 5 | 637 | ---- | ---- | 5.64% |
| Processing 6 | 650 | ---- | ---- | 7.79% |
| Processing 7 | 610 | ---- | ---- | 1.16% |
| Processing 8 | 628 | ---- | ---- | 4.15% |
| Processing 9 | 625 | ---- | ---- | 3.65% |
| Processing 10 | 608 | ---- | ---- | 0.83% |
| Processing 11 | 605 | ---- | ---- | 0.33% |
| Processing 12 | 600 | ---- | ---- | - 0.5% |
It can be seen that (1) processing 2 than 1 underproduction 13.80% of processing, illustrates urea decomposition speed mistake by experimental result in table 1
It fastly, can be because of the underproduction caused by de- fertilizer after the typhon phase；(2) processing 3 illustrates that DMPP can press down than 2 volume increase 17.77% of processing
The nitrification of ammonium nitrogen in antidiuresis element and compound fertilizer, to reduce the loss of fertilizer；(3) processing 4-11 is compared with processing 3,
There is different degrees of volume increase, illustrates that the stable nitrification inhibitor of 1-8 of embodiment of the present invention preparation is able to suppress DMPP volatilization, tool
There is the effect for preferably inhibiting nitrogenous fertilizer nitrification；(4) as can be seen that stable nitrification prepared by the present invention from processing 4-11
It than protective agent is only what protective colloid obtained when protective agent is the mixture of protective colloid and soluble starch in inhibitor
The effect of the inhibition nitrogenous fertilizer nitrification of stable nitrification inhibitor is good, and can be seen that when protective agent is gum arabic
When the mixture of powder, gelatin and soluble starch, obtained nitrification inhibitor inhibits the effect of nitrogenous fertilizer nitrification more preferable；(5)
From processing 12 as can be seen that nitrification inhibitor prepared by comparative example 1, when protective agent is only soluble starch, obtained nitrification presses down
Preparation does not have the effect for inhibiting nitrogenous fertilizer nitrification well.
The stable nitrification inhibitor and fertilizer prepared through the invention is in use, can effectively inhibit nitrogenous fertilizer
Nitrification inhibits conversion of the ammonium nitrogen to nitrate nitrogen in nitrogenous fertilizer, reduces the loss of nitrogenous fertilizer and improves the utilization rate of nitrogenous fertilizer, is mentioning
While high Economic Benefit of Agricultural Production, alleviate the environmental problem caused using nitrogenous fertilizer.
