Plant water-culture device for purifying indoor formaldehyde and water-culture method using device

Abstract

The invention relates to a plant water-culture device and a water-culture method by using the device, particularly a plant water-culture device for purifying indoor formaldehyde and a water-culture method by using the device. The device comprises a main box body made of stainless steel or glass, a water outlet tap, canework covers and a pedestal, wherein upper openings of the box body with openings in the upper end have different heights, and the height of the opening of one half is 3-5cm higher than that of the other half; the canework covers are arranged on the upper part of the box body; holes are formed in the canework covers and used for arranging plants; gravel is arranged in the box body and used for fixing aloes and chlorophytum comosum; the lower end of the box body is provided with the water outlet tap; the whole box body is installed on the pedestal; and the pedestal is composed of a wood board and four pulleys. By using the characteristic that the chlorophytum comosum and aloes can absorb formaldehyde, the simple experimental device is adopted to promote the interactions of root exudates of the chlorophytum comosum and aloes, thereby being beneficial to plant growth and enhancing the formaldehyde absorptivity. Meanwhile, a reasonable culture method and a nutrient solution are utilized to promote the plant growth and enhance the formaldehyde absorptivity of the plants.

Description

technical field [0001] The invention relates to a plant cultivation device and a method thereof, in particular to a plant hydroponic device and a hydroponic method for purifying indoor formaldehyde. Background technique [0002] Through the environmental testing of many well-decorated houses, the structure shows that the concentration of formaldehyde generally exceeds the standard. If control measures are not taken, it will bring great harm to human health: direct contact with formaldehyde on the skin can cause allergic dermatitis, stains, necrosis , inhalation of high concentrations of formaldehyde can induce bronchial asthma; formaldehyde is a protoplasmic toxic substance that can be combined with proteins, and severe respiratory tract irritation, edema, eye irritation, and headaches occur when inhaled at high concentrations; experimental animals are inhaled at high concentrations in the laboratory. Formaldehyde can cause nasopharyngeal tumors; at the same time, formaldehy...

AI Technical Summary

Problems solved by technology

Someone tested the ability of ivy, spider plant, aloe, pothos, and clivia to absorb formaldehyde through fumigation experiments. The results showed that ivy and pothos had strong ability to absorb formaldehyde, but the resistance after absorption was weak, while Chlorophytum and aloe had strong ability to absorb formaldehyde.
