Problems solved by technology

[0002] my country is a country with a large population and a large agriculture. Food security is the country's primary issue. Fertilizer is an important means of agricultural production. The production and consumption of chemical fertilizers in my country rank first in the world, contributing more than 50% to food production. While ensuring high agricultural production, the amount of chemical fertilizer application has also brought problems that cannot be ignored. First, the low utilization rate of chemical fertilizers has led to excessive consumption of chemical fertilizer resources and at the same time caused environmental pollution.
Secondly, the excessive application of chemical fertilizers will increase the input of agricultural costs

Abstract

The invention relates to synergistic urea enveloped by compound plant oil and a method for producing the synergistic urea. The synergistic urea enveloped by the compound plant oil comprises granular urea and compound plant oil enveloped layers. The compound plant oil enveloped layers comprise chinaberry oil, plant oil and paraffin. The synergistic urea enveloped by the compound plant oil and the method have the advantages that the synergistic urea is good in urea sustained-release performance, the nitrification inhibition rate is 20%-50% and is more than three times higher than the nitrification inhibition rate specified by national chemical industry standards, and accordingly the fertilizer application rates can be reduced; the synergistic urea contains the chinaberry seed oil, accordingly, pesticide consumption can be reduced, and the synergistic urea completely conforms to national fertilizer and pesticide double-decrease policy.
