Problems solved by technology

[0004] The research on nitrification inhibitors in foreign countries started very early and has achieved remarkable results. There are many experiments and promotions in field applications. According to statistics, the amount of chemical fertilizer per unit area in my country is 2.7 times higher than the world's average level. The resulting ecological and environmental pressure Doubled with the day, but our research in this area is relatively backward

Abstract

The invention relates to the field of nitrification inhibitors, in particular to application of methyl cinnamate used as a nitrification inhibitor. Through pure strain cultivating and soil adding tests, the methyl cinnamate is proved to have a favorable nitrification inhibition effect, can be applied as the bio-nitrification inhibitor, and has a better nitrification inhibition effect. The invention also relates to an agricultural composition which comprises at least one nitrification inhibitor including the methyl cinnamate. After the agricultural composition is applied to soil, N element conversion can be effectively regulated and controlled.

Description

Technical field [0001] The present invention relates to the field of nitrification inhibitors, and specifically to the use of methyl cinnamate as a nitrification inhibitor. Background technique [0002] Nitrogen is an essential nutrient element for plants and the most important nutrient limiting factor for crop yield. The application of nitrogen fertilizer has become a necessary way for agricultural producers to obtain high yields. According to estimates by the Food and Agriculture Organization of the United Nations, more than 55% of the increase in grain production in developing countries is attributed to chemical fertilizers, of which nitrogen fertilizers play a crucial role. However, excessive and irrational application of fertilizer nitrogen and its rapid hydrolysis and nitrification in the soil result in generally low nitrogen utilization efficiency. At present, the average nitrogen fertilizer utilization rate in my country's agricultural production is only about 20%-3...
