Abstract

The invention discloses a novel graphene fertilizer and a preparation method thereof. The fertilizer is mainly prepared from graphene, expanded vermiculite powder, soybean cake, distillers' grains, barnyard manure, straw, rapeseed oil, rice bran and water. The dispersion effect of graphene is improved by conducting ball-milling on the expanded vermiculite powder and graphene; meanwhile, due to the fact that the raw materials containing plant fiber are used in the fertilizer, the loss of effective ingredients in the fertilizer is greatly reduced, and the use effect of the fertilizer is improved; in the actual usage process, the use amount of the fertilizer can reduced by 50% or above, and the yield is increased by 15%-20%.

Description

Technical field [0001] The invention relates to the technical field of fertilizers, in particular to a new type of graphene fertilizer and a preparation method thereof. Background technique [0002] Graphene is a two-dimensional crystal composed of carbon atoms with a thickness of only one layer. In 2004, physicists Andre Gaim and Konstantin Novoselov of the University of Manchester in the United Kingdom successfully separated graphene from graphite and confirmed that it can exist alone, and the two also jointly won the 2010 promise. Bell Prize in Physics. [0003] Before the discovery of boronene at the end of 2015, graphene was both the thinnest material and the strongest material, with a fracture strength 200 times higher than the best steel. At the same time, it has good elasticity, and the stretching range can reach 20% of its own size. It is currently the thinnest and strongest material in nature. If a piece of graphene with an area of ​​1 square meter is used to make a ha...
