Problems solved by technology

[0003] The urease inhibitors that have been identified mainly include heavy metal ions, metal complexes, phosphoramides, hydroxamic acids, etc. However, most of the above urease inhibitors have problems such as unstable effects, high toxicity, and easy degradation, so it is difficult to It is widely used in different regions, and long-term application may cause pollution to the environment. Compared with artificial chemically synthesized urease inhibitors, extracts from plants are natural compounds and have little impact on the ecological environment. Therefore, screening New high-efficiency and low-toxicity urease inhibitor can contribute to the green development of agriculture

Abstract

The invention discloses application of farnesene in preparation of a plant-derived urease inhibitor, and belongs to the technical field of urease inhibitors. The compound can effectively inhibit the activity of concanavalin urease and soil urease, and the effect of the compound can be equivalent to that of a commercial urease inhibitor acetohydroxamic acid. The urease inhibiting substance provided by the invention is derived from plants, has the characteristic of'green 'of a natural product, is high in biological safety, simple and stable in chemical structure and remarkable in urease inhibiting effect, can solve the problems of high toxicity, easiness in degradation and poor stability of a conventional chemically synthesized urease inhibitor, and has a wide application prospect. Meanwhile, a new thought is provided for creating a biological and ecological technology for efficiently inhibiting rapid hydrolysis of farmland urea and improving the utilization rate of urea nitrogen fertilizer, and good application value and development prospects are achieved.

Description

technical field [0001] The present invention relates to the technical field of urease inhibitors, in particular to the application of farnesene in the preparation of plant-derived urease inhibitors. Background technique [0002] Urea is the most common type of nitrogen fertilizer, with high nutrients and low cost, and is widely used in agricultural production. However, the direct application of urea has the disadvantages of fast nutrient conversion and low nitrogen utilization rate. The urea applied to the soil quickly generates ammonium nitrogen under the hydrolysis of urease, and only 30% to 60% of the nitrogen is absorbed and utilized by crops. A large amount of urea Application not only causes economic and resource waste, but also leads to environmental problems such as soil acidification and compaction, water eutrophication and air pollution. Since the 1960s, all countries in the world have carried out a series of research work on delaying urea hydrolysis and nutrient ...
