Simultaneously it has been found that methyl cinnamate and DCD compoundings can be obviously improved its nitrite production inhibiting rate, with
Total mole number is 0.01mM, sets the methyl cinnamate of different mol ratio：The experimental group of DCD carries out experimental verification；Simultaneously with it is total
Molal quantity is the methyl cinnamate of 0.01mM different mol ratios：The control group of DMPP is compared, and is repeated to Nitrosomonas
The inhibition experiment of europaea, the results are shown in table below：
As can be known from the above table, by methyl cinnamate and DCD compounding have significant synergies, especially methyl cinnamate with
The molar ratio of DCD is 4:Synergistic effect is especially notable when 1 or even has more preferably inhibition than DMPP is used alone.But meat
Acid methylester does not show synergistic effect with DMPP.
Further to verify the compounding effect of methyl cinnamate and DCD, applicant uses Nitrosospira
Multiformis ATCC 25196 (N1), two kinds of Nitrosococcus oceani ATCC 19707 (N2) common ammonia oxygen
Change bacterium further carries out nitrite production Inhibition test and is verified, wherein the total addition level of various inhibitor is
0.01mM, the molar ratio of methyl cinnamate and DCD are 4 in methyl cinnamate-DCD compounding groups:1；To nitro-methyl cinnamate-
4 are similarly to the molar ratio of nitro-methyl cinnamate and DCD in DCD compounding groups:1.The results are shown in table below.
As can be known from the above table, methyl cinnamate also has N1, N2 good inhibition, and methyl cinnamate-DCD is compounded
Group best results.
(2) pedotheque (15g, oven-dry weight) is added in 100mL conical flasks, with distillation water process to reach
40% moisture-holding capacity (water holding capacity).Sample is incubated 7 days with stabilised microorganism in the dark at 25 DEG C
Activity.Then the aerobic culture experiment of 28 days is carried out, to study the reaction that soil nitrification adds different nitrification inhibitors.It will
NH4Cl solution is added in each conical flask to provide 400mg N kg-1The NH of native (dry ground calculating)4Cl solution.It is following
The dosage of group nitrification inhibitor is 100 μm of ol kg-1In dry ground, wherein methyl cinnamate-DCD compoundings group methyl cinnamate and
The molar ratio of DCD is 4:1；To in nitro-methyl cinnamate-DCD compounding groups to the molar ratio of nitro-methyl cinnamate and DCD
It is similarly 4:1.Measure NH within the 3rd, 7,14 and 28 day in incubation4 +- N and NO3 -The concentration of-N, is calculated by the following formula
Nitrifying inhibition rate (NI)：
Nitrification inhibition Nitrifying inhibition rates (NI%)=(the Nitrification rate nitrification of control
The Nitrification rate nitrification rate in sample of rate in control- samples)/control Nitrification rate
Nitrification rate in control × 100%
Explanation：Control refers to the experimental group for being not added with nitrification inhibitor, and sample refers to the experimental group of addition nitrification inhibitor.
Nitrification rate nitrification rate (%)=NO in above formula3 --N/(NH4 +-N+NO3 -- N) × 100%
Result above is briefly described：As can be seen that methyl cinnamate can keep relatively steady in 28 days in soil incubation
Fixed Nitrifying inhibition rate (＞ 25%), but its effect in the soil is poorer than the nitrification inhibitor DMPP of commercialization.However Chinese cassia tree
Sour methyl esters-DCD compounding group effects are but obviously improved with DMPP ratios.It is poor to nitro-methyl cinnamate nitrification inhibition, with
