Application of 1,9-decanediol in inhibiting soil ammonia volatilization

Abstract

Application of 1,9-decanediol in inhibiting soil ammonia volatilization. It was found that 1,9-decanediol has a two-way regulation effect, which can not only significantly inhibit the volatilization of soil ammonia, but also effectively inhibit the nitrification process of nitrogen, and play a synergistic role. As a fat-soluble substance, 1,9-decanediol, It has high stability in the soil and is not easy to separate from nitrogen fertilizer. As a plant root exudate, 1,9-decanediol also has the advantages of being green, safe and pollution-free, which broadens the application field of 1,9-decanediol and improves the industrial application value of 1,9-decanediol. methods and ideas.

Description

technical field [0001] The invention belongs to the research field of nitrogen fertilizer synergists, in particular 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 rapidly converted into ammonium nitrogen under the action of urease, ammonium nitrogen will be transformed into nitrate nitrogen under the action of nitrification, and nitrate nitrogen will be transformed into nitrous oxide and nitrous oxide under the action of denitrification. and nitrogen; the accumulation of ammonium nitrogen in the soil will cause the soil pH to rise, so that the ammonium nitrogen is converted into ammonia and volatilized into the air. These methods make the nitrogen fertilizer utilization rate in the current season only 35% to 39%. Among them, the loss of ammonia volatilization in farmland can reach 20% to 47% of the nitrogen application amount. Therefore, reducing ammonia...
