Nitrification inhibitor compounding effect in 1 charcoal fertilizer of experimental example
(1) inhibition of pure ammonia oxidizing bacteria Nitrosomonas europaea (ATCC 19718) is tested：
The pure culture base of Nitrosomonas europaea (contains 2.5g (NH in 1L sterile waters4)2SO4,0.5g KH2PO4,5mg
CaCl2.2H2O,0.1g MgSO4.7H2O,0.5g NaHCO3,1g NaCl,1mL 75mg FeNaEDTA,11.92g HEPES)
The middle methyl cinnamate for adding in various concentration calculates what is generated to nitro-methyl cinnamate, DMPP and dicyandiamide (abbreviation DCD)
NO2 -- N concentration reacts nitrification inhibition with NPI：
Nitrite production inhibiting rate Nitrite production inhibition (NPI%)=(1- (NO2 - sample-
NO2 - initial)/(NO2 - control-NO2 - initial)) × 100%
Result of the test：NPI%
Result above is briefly described：As can be seen that when the addition concentration of methyl cinnamate reaches 1mM, (1 mM every
Rise) when, the nitrosation process inhibiting rate of Nitrosomonas europaea is reached 100%, 0.1mM also have very may be used
The inhibition (reaching 98.8%) of sight, with the reduction of addition concentration, inhibition gradually weakens.DMPP is most general at present
All over, be also to generally acknowledge the best nitrification inhibitor of effect, therefore the application using DMPP products as control, it can be seen that higher
When concentration is added, methyl cinnamate inhibits the effect of nitrification close with DMPP, slightly less than DMPP when low concentration adds.It is all
Cinnamic acid derivative it is very poor to nitro-methyl cinnamate nitrification inhibition.
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
There is no synergistic effects for DCD compoundings.
Application of 2 charcoal fertilizer of experimental example in corn planting
Experiment is Zheng Dan 958 with corn variety, and experiment is Fluvo-Aquic Soils with soil, collected from Shandong Province Gaotang County Zhao Zhuan villages
Experimental field 0~20cm topsoils.Physiochemical properties of soil：PH value 8.48, organic matter 18.4gkg-1, full nitrogen 1.02gkg-1,
Full phosphorus 1.89gkg-1, full potassium 3.85gkg-1, alkali-hydrolyzable nitrogen 52.41mgkg-1, rapid available phosphorus 13.82mgkg-1, available potassium
120mg·kg-1.After soil air-dries, ground 2mm sieves are for pot experiment.Add native 7.5kg per basin.Corn seed is soaked seed 12h
Afterwards, in pearlite interstitial substance culture nursery.It when maize seedling length to 2 complete leaves, transplants in basin, per 1 plant of maize seedling of basin.
It is 1.0gkg per basin fertilizer applied amount-1(dry ground) only does single-dose application, no longer top dressing, totally 7 processing, often
A processing is repeated 3 times.Specific test process fertilizer applications see the table below：
Assay method is：
Corn measures plant height after transplanting 3 months；It after harvest corn, finishes, dry immediately, then claim stalk and seed respectively
Dry weight.And then the stalk of drying and seed are crushed respectively, reference《Soil Analysis in Agricultural Chemistry》(Bao Shidan chief editors) measures respectively
The nitrogen content of stalk and seed.
Influence of the 1 each group fertilizer of table to corn plant height
| Group | Plant height (cm) |
| CK | 124.5d |
| LB | 162.7a |
| Con1 | 138.7c |
| Con2 | 152.4b |
| Con3 | 148.8b |
| Con4 | 87.4e |
| Con5 | 140.1bc |
As it can be seen from table 1 papermaking wastewater lignin is directly manured into soil (Con4) to corn in moisture soil as fertilizer
Growth is very unfavorable, and plant height is even substantially less than the CK processing do not applied fertilizer, and papermaking wastewater lignin is processed as charcoal
It can significantly increase corn plant height with CK using (LB, Con1-3, Con5) is then opposite.In addition, with the plant height of LB in all processing
Highest, and be significantly higher than Con1-3,5 groups, illustrate after papermaking wastewater lignin is processed as charcoal, and with attapulgite, sea
The fertilizer efficiency that particular organisms charcoal fertilizer is made in the compoundings such as afrodite, methyl cinnamate is best.
Influence of the 2 each group fertilizer of table to maize straw and seed biomass
| Group | Straw biological amount (gpot-1) | Seed biomass (gpot-1) |
| CK | 64.8d | 27.7e |
| LB | 131.9a | 68.0a |
| Con1 | 102.3c | 46.7d |
| Con2 | 117.6b | 61.5b |
| Con3 | 110.7bc | 52.8c |
| Con4 | 43.4e | 18.9f |
| Con5 | 99.3c | 50.3c |
Equally, as known from Table 2, influence of each group fertilizer to maize straw and seed biomass is also substantially similar to plant height.
Con4 is very unfavorable to the biomass of maize straw and seed, and the CK processing that numerical value does not apply fertilizer substantially less than illustrates papermaking
Waste liquor lignin, which is directly manured into soil, seriously inhibits corn normal growth.In all processing, still with the stalk of LB, seed biomass
Highest, and it is significantly higher than other processing, it further proves after papermaking wastewater lignin is processed as charcoal, and and concave convex rod
Soil, sepiolite, methyl cinnamate etc. carry out compounding and particular organisms charcoal fertilizer are made effect is obviously promoted to corn growth.
Influence of the 3 each group fertilizer of table to maize straw and seed nitrogen content
| Group | Stalk leaded wastewater (%) | Seed leaded wastewater (%) |
| CK | 0.83d | 1.49e |
| LB | 1.05a | 1.76a |
| Con1 | 0.96bc | 1.62c |
| Con2 | 1.02b | 1.72b |
| Con3 | 1.01b | 1.69b |
| Con4 | 0.92c | 1.55d |
| Con5 | 0.99b | 1.68b |
From table 3 it can be seen that LB processing also significantly increases the nitrogen content in maize straw and seed, numerical value is all
Highest in processing.This also illustrates after papermaking wastewater lignin is processed as charcoal, and with attapulgite, sepiolite, cinnamic acid
Particular organisms charcoal fertilizer, which is made, in methyl esters etc. can improve the nitrogen nutrition of soil, promote the Nitrogen Absorption of corn, so as to be effectively improved
Corn quality improves utilization rate of nitrogen fertilizer.
Corn yield is high, nitrogen requirement is big, and in China, cultivated area is wider.But during corn planting, peasant habit in
During nitrogenous fertilizer is disposably manured into soil in corn seeding, cause most of nitrogen since corn is few to Nitrogen Absorption in early stage
It is lost in.From experimental example 1 and 2 it is found that charcoal fertilizer provided by the present invention can effectively inhibit nitrification, so as to postpone urea
Nitrogenous fertilizer is waited to the conversion of nitrate nitrogen, to reduce the loss of N fertilizer in the soil, moreover it is possible to the supply of early stage N fertilizer be avoided excessively to cause burn seedlings.In addition
Charcoal, attapulgite, sepiolite may also function as slow releasing function, can extend the conventional nitrogenous fertilizer such as urea in the corn growth later stage
For nitrogen ability, promote corn growth, improve corn yield and quality.
