Problems solved by technology

[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 substances in the nutrient solution leads to poor dispersion and uniformity of various inorganic and organic nutrients in the culture solution, and there are differences in local concentrations in the nutrient solution, which affects 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

Abstract

The invention relates to a soilless culture liquid medium for ecological tourism agriculture and a preparation method of the soilless culture liquid medium. The soilless culture liquid medium is prepared from basic culture solution, a bactericidal agent and an ammonium polyphosphate-diatomite / graphene composite nanomaterial additive. A preparation method of the ammonium polyphosphate-diatomite / graphene composite nanomaterial includes steps: pouring phosphoric acid with the mass fraction of 70-85% into a reactor, heating, stirring, adding urea and diatomite when the temperature is 75-80 DEG C,adding nano graphene when the temperature is 110-120 DEG C, continuing heating to 120-130 DEG C after material adding, performing stirring reaction for 10-20min, subjecting a product to high-temperature treatment for 3-5h at 160-180 DEG C, cooling to the room temperature, and performing nano grinding to obtain the ammonium polyphosphate-diatomite / graphene composite nanomaterial. The soilless culture liquid medium for ecological tourism agriculture is high in dispersity and uniformity, local concentration difference is overcome, and plants are free of root rot, stink and undesirable odor and grow normally in indoor cultivation.

Description

technical field [0001] The invention relates to a culture solution and a preparation method thereof, in particular to a soilless culture liquid substrate for ecological sightseeing agriculture 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 solu...
