The invention discloses application of 1, 9-decanediol in inhibition of soil ammonia volatilization. The invention finds that 1, 9-decanediol has a bidirectional regulation effect, not only can significantly inhibit soil ammonia volatilization, but also can effectively inhibit the nitrification process of nitrogen, and 1, 9-decanediol, as a fat-soluble substance, has high stability in soil and is not easy to separate from a nitrogen fertilizer under the synergistic interaction effect. The 1, 9-decanediol serving as the plant root exudates also has the advantages of being green, safe and free of pollution, so that the application field of the 1, 9-decanediol is widened, and a new method and thought are provided for improving the industrial application value of the 1, 9-decanediol.
Description
technical field [0001] The invention belongs to the research field of nitrogen fertilizer synergists, and specifically relates to the application of 1,9-decanediol in inhibiting soil ammonia volatilization. Background technique [0002] When nitrogen fertilizer is applied to the soil, it will be quickly converted into ammonium nitrogen under the action of urease, ammonium nitrogen will be converted into nitrate nitrogen under the action of nitrification, and nitrate nitrogen will be converted into nitrous oxide and nitrous oxide under the action of denitrification. And nitrogen; the accumulation of ammonium nitrogen in the soil will cause the pH of the soil to rise, so that the ammonium nitrogen will be converted into ammonia and volatilized into the air. These methods make the nitrogen use efficiency of the season only 35% to 39%. Among them, the amount of ammonia volatilization loss in farmland can reach 20% to 47% of the nitrogen application rate. Therefore, reducing ammo...
