Abstract

The invention discloses a graphene soil amendment and a preparation method thereof. The soil amendment comprises the following components: 1000 parts of an active liquid fertilizer base preparation, 2-7 parts of graphene, 5-12 parts of nodule bacteria, 1-3 parts of penicilliums, 12-26 parts of chitosan and 35-42 parts of amino acids. The soil amendment provided by the invention is obtained creatively through fermentation of the nodule bacteria, is safe and environmentally friendly; a strain culture prepared by microbial fermentation is combined with the penicilliums to produce a plurality of microbial bacteria, so that soil acid-base balance can be permanently improved; and the soil amendment effectively promotes growth and development of plants, and enhances root gripping force of the plants to make the plants adapt to desertified land.

Description

technical field [0001] The invention belongs to the technical field of remediation agents, more specifically, relates to a graphene soil remediation agent. Background technique [0002] At present, the soil in many places in our country is barren, which makes the land unable to grow crops and makes a large area of ​​land deserted. The comprehensive characterization of soil environment and soil physical, chemical and biological characteristics degradation, showing the decline of organic matter content, nutrient element deficiency, soil structure damage, soil erosion, soil layer thinning, soil compaction, easy to cause soil acidification and alkalization , desertification, etc. Among these characterizations, a decline in organic matter content can serve as an important indicator of soil degradation, which is linked to many soil properties. For example, the black soil newly cultivated in Northeast my country has an organic matter content of 7-10%, but within a hundred years o...
