Graphene-modified culture solution for indoor hydroponic plants and preparation method of graphene-modified culture solution

Abstract

The invention relates to a graphene-modified culture solution for indoor hydroponic plants and a preparation method of the graphene-modified culture solution. The graphene-modified culture solution isprepared from basic culture liquid and additives of ammonium polyphosphate-organic bentonite / graphene composite nanomaterials, wherein a preparation method of the ammonium polyphosphate-organic bentonite / graphene composite nanomaterials comprises the steps of: pouring phosphoric acid with the mass fraction of 70-85% into a reactor, performing heating and stirring, and adding urea and organic bentonite into the reactor when the temperature rises to 75-80 DEG C; adding nano graphene into the reactor when the temperature rises to 110-120 DEG C, keeping raising the temperature to 120-130 DEG C after all the materials are added into the reactor, performing a reaction with stirring for 10-20 min, then performing high temperature treatment on products at 160-180 DEG C for 3-5 h, decreasing the temperature to a room temperature, and performing nano-pulverization to obtain the ammonium polyphosphate-organic bentonite / graphene composite nanomaterials. The graphene-modified culture solution forthe indoor hydroponic plants has good dispersibility and uniformity, the difference of local concentration in the nutrient solution can be avoided, and the plants have no rotten roots, odor and smell,and can grow normally during indoor culture.

Description

technical field [0001] The invention relates to a culture solution and a preparation method thereof, in particular to a graphene-modified indoor hydroponic plant culture solution and a preparation method thereof, belonging to the technical field of soilless cultivation. Background technique [0002] Most of the indoor hydroponic plants are soilless cultivation without medium. In the absence of medium, the plants are prone to rotten roots, smelly and breeding mosquitoes. The reason is that the inevitable aggregation of macromolecular organic matter in the nutrient solution leads to poor dispersion and uniformity of various inorganic and organic nutrients in the nutrient solution, and local concentration differences in the nutrient solution affect the healthy growth of plant roots. At the same time, insufficient indoor light can easily lead to hypoxia, incomplete photosynthetic reaction of plants, and slow growth. Therefore, it is required that the nutrient solution must have...
