Urea is a nitrogen fertilizer with the largest proportion, the total amount of applied global nitrogen fertilizer in 2018 reaches 1.07 hundred million tons, the urea accounts for about 55 percent, the annual capacity of the Chinese nitrogen fertilizer in recent years is about 4000 million tons, and the urea accounts for about 68 percent. Urease can be present at 10 14 The rate of catalytic decomposition of urea into carbon dioxide and ammonia is doubled, and urease is an inducible enzyme and has high degree of activitySpecificity, and only has catalytic action on urea. Under the action of soil urease, urea is rapidly hydrolyzed, the decomposition rate in 15 days reaches 98%, so that the retention time of the urea in the soil is greatly shortened, the utilization rate of urea nitrogen is obviously reduced, the volatilization of soil ammonia is obviously increased, and serious environmental problems are caused.
The urease inhibitor is a substance capable of effectively reducing the activity of urease, and can effectively delay the hydrolysis of urea and prolong the retention time and fertilizer efficiency of urea in soil, thereby improving the utilization efficiency of the urea. The N-butyl thiophosphoric triamide (NBPT) can generate high-efficiency urease inhibiting effect due to low addition amount, is distinguished from a plurality of urease inhibitors, and is the current mainstream urease inhibitor. Results of a global scale Meta-analysis study show that NBPT addition to urea can increase crop yield by 6% on average and reduce ammonia emission by 53%. However, a number of literature studies have shown that NBPT has no significant urease inhibiting effect in acidic soils (pH < 5.5) and no ammonia gas abatement effect. Therefore, it is important to screen substances that can produce a high urease inhibiting effect in acidic soil.

It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Example 1 inhibition of urease by poly-gamma-glutamic acid in acid brown soil:
1. and (3) verification test:
the greenhouse pot experiment is carried out at the research institute of the tobacco terrace coastal zone of the Chinese academy of sciences. The potting test soil was representative dry land cultivation layer 0-20cm brown soil (N41 '49', E123 '34' 4 ") collected from a typical brown soil long term location test station in northeast of Shenyang agricultural university, soil pH (water to soil ratio of 1. The fertilization level (N-P2O 5-K2O) of the potting soil is 360-150-300, the addition amount of poly-gamma-glutamic acid is 30mg/kg of soil, the nitrogen fertilizer is urea, the phosphate fertilizer is superphosphate monohydrate, and the potassium fertilizer is potassium sulfate. Uniformly mixing poly-gamma-glutamic acid, urea, calcium superphosphate monohydrate and potassium sulfate, dissolving the mixture in an aqueous solution, uniformly pouring the aqueous solution on the soil surface, and not additionally applying other fertilizers in the later period. Soil was harvested at 1,3,7, 15, 25, 40 and 55 days after fertilization for urease activity, while the absolute abundance (copy number) of the ureC functional gene encoding urease was determined by real-time fluorescent quantitative PCR and the community structure change of the ureC functional gene was determined by high throughput sequencing molecular biology.
2. Comparative experiment 1:
the method is characterized in that the method is carried out in a research institute of a tobacco terrace coastal zone of China academy of sciences, the experimental conditions are consistent with the verification test, only poly-gamma-glutamic acid is not added into the urea, and urea containing nitrogen and other nitrogen in the poly-gamma-glutamic acid is correspondingly supplemented to the soil of the verification test in order to eliminate the influence of nitrogen nutrients of the poly-gamma-glutamic acid.
3. As a result, the
The Urease content in the test soil (UP) is remarkably smaller than the Urease (Urease) activity (13.00% -16.39%) in the soil (U) of the comparative test 1 from day 1 to day 45 (p <0.05, figure 1), and the reduction amplitudes at days 1,3,7, 15, 25 and 45 are respectively 13.04%, 14.01%, 14.47%, 13.83%, 13.00% and 16.39%, which shows that the poly-gamma-glutamic acid is remarkably inhibited and reduced in the Urease activity in the acid brown soil and has remarkable Urease inhibiting effect.
Meanwhile, the determination result of the real-time fluorescent quantitative PCR method shows that the absolute abundance (copy number) of the ureC of the functional gene encoding urease in the soil in the verification test is reduced by 34.50-175.18%, and the addition of poly-gamma-glutamic acid is proved to obviously inhibit the activity of the urease. The results of high throughput sequencing showed unclassified _ d _ Bacteria (19.95%), bradyrhizobium (11.11%), mesorhizobium (5.10%), rhodopseudomonas (2.99%) were the dominant species in soil, PCoA Analysis (ANOSIM) found to verify that the ureC functional gene microbial communities in the test soil (UP) and the comparative test soil (U) could be clearly distinguished (R =1.00, p =0.098, fig. 2), verifying that the relative abundance of Bradyrhizobium, rhodopseudomonas, leptrix R _ ror, pseudomonas brot, caballeronia, stella, variovax in the test soil was significantly reduced (p <0.01, fig. 3). Thus, the assay results of high throughput sequencing indicate that poly-gamma-glutamate addition causes significant changes in the composition of the ureC functional gene microbial community and significantly reduces the relative abundance (genus level) of the dominant species of Bradyrhizobium and Rhodopseudomonas.
Example 2 inhibitory effect of poly-gamma-glutamic acid on urease in neutral brown soil:

Uniformly mixing poly-gamma-glutamic acid with urea, calcium superphosphate monohydrate and potassium sulfate, dissolving the mixture in an aqueous solution, and injecting the solution into soil without applying other fertilizers in the later stage. Soil was collected on days 1,3,7, 15, 30, 45 and 60 after fertilization for urease activity.
2. And (3) comparison test:
