Soil quality can also be improved simultaneously, to achieve the purpose that volume increase, therefore fertilizer is in the evolution of agricultural science and technology, can
Play the role of it is vital, but at present on the market used in fertilizer because be formulated unreasonable or processing technology the problems such as,
The case where during fertilising, utilization rate is poor, and there are the wastings of resources, and part fertilizer can lead to the structure for destroying soil,
So that soil is hardened, can not effectively utilize soil, and fertilizer the case where it is easy to appear fertilizer losses in use, leads
The utility to cause fat in expecting is not absorbed by crops, and to cause utilization rate of fertilizer low, and existing fertilizer will produce to ring
The harmful substance in border brings prodigious destruction to environment, does not meet the environment protection thought of modern people.
Graphene is a kind of two dimensional crystal, and the common graphite of people is the planar carbon by being arranged from level to level with honeycomb-patterned ordered
Atom stack and formed, the interlaminar action power of graphite is weaker, it is easy to mutually stripping, very thin graphite flake is formed, when stone
After ink sheet stripping is at single layer, this is exactly graphene there are one the single layer of carbon atom thickness, and the latest find of graphene is people
In terms of anticorrosion most efficient method, common polymer coating be easy to be scraped off, reduce protective value, and graphite
Alkene does protective film, has significantly delayed corrosion of metal speed, firmer antibody Monoclonal, because of this characteristic that graphene has,
To make graphene can be applied to each different field.
