Nano carbon long-acting environment friendly compound fertilizer

Abstract

The invention provides a fertilizer containing carbon, which is added with 5-200nm of carbon nanophase materials with 0.1-1 percent of weight and is preferably added with 5-100nm of carbon nanophase materials with 0.1-0.5 percent of weight as well as is added with 0.2-0.7 percent of ammonia stabilizing agents or nitratase inhibitor. The invention particularly relates to a nanometer carbon compound fertilizer of ammonium bicarbonate, which is environment-friendly for a long time and has obvious effects of carbon emission reduction and synergy.

Description

technical field [0001] The present invention relates to carbon-containing fertilizers, in particular to carbon-containing fertilizers with reduced greenhouse gas emissions. Background technique [0002] Carbon-containing fertilizers mainly refer to ammonium bicarbonate and urea, especially ammonium bicarbonate. As a chemical nitrogen fertilizer, ammonium bicarbonate fertilizer is suitable for various soils and crops. It has fast fertilizer effect and will not acidify the soil. But this fertilizer also has its disadvantages. It is easy to decompose under the condition of high temperature and moisture. Generally, the nitrogen utilization rate of this fertilizer is only 25% to 30%, and the fertilizer effect period is only 30 to 40 days. [0003] CN1053225A discloses a kind of chemical fertilizer long-acting ammonium bicarbonate and its preparation method. It is to add a small amount of dicyandiamide (DCD) in ammonium bicarbonate to form a co-crystal or a mixture. The process ...
