Embodiment Construction
[0020] The present invention will be further described below in conjunction with specific examples.
[0021] The area of the test site is 23.4m 2 , 4.2m high, total volume 98.28m 3 , about 100m 3 .
[0022] For the test, yew potted plants cultivated in vermicompost substrate with high-efficiency absorption of indoor formaldehyde. The flowerpot is made of ceramics, with a height of 35cm, a lower diameter of 30cm, an upper diameter of 40cm, and a porous bottom; 16 layers of gauze are placed on the bottom of the flowerpot, and then filled with vermicompost The substrate is up to 20cm high, and a 3-year-old Mandia yew plant is planted, covered with 5cm thick pure vermicompost.
[0023] The vermicompost matrix contains, by volume percentage: 55% of cow dung vermicompost, 20% of vermiculite particles, and 25% of perlite particles, which are fully mixed. In the vermicompost matrix, the diameter of cow dung and vermicompost particles is 1-4mm, the diameter of vermiculite particl...

Abstract
The invention relates to taxus chinensis potted plants with the function of efficiently absorbing indoor formaldehyde cultivated by an earthworm dejecta substrate and a preparation method thereof and application. The potted plants comprise flowerpots planted with taxus chinensis plants and filled with the earthworm dejecta substrate and pure wormcast. The earthworm dejecta substrate is formed by full mixing of 55% of cow dung wormcast, 20% of vermiculite granules, 25% of perlite perlite based on volume percentage. Pure wormcast is a product of earthworm resolution and is cow dung and wormcast.The taxus chinensis potted plants with function of efficiently absorbing indoor formaldehyde cultivated by the earthworm dejecta substrate and the preparation method thereof and the application have following beneficial effects: the technological difficulties for continuous and rapid elimination of indoor formaldehyde on the condition of low cost are solved; wormcast is loose and porous and shows greater adsorptive property than activated carbon; taxus chinensis plants can absorb indoor formaldehyde and methylbenzene and other gases; meanwhile, wormcast has good porosity, vent ability, water permeability and higher water-holding capacity; due to high organic matter and nutrient content, growth of taxus chinensis is significantly prompted so that the taxus chinensis exerts its effect of absorbing and purifying indoor formaldehyde.
Description
technical field [0001] The invention relates to a vermicompost-based yew potted plant and a preparation and application method thereof, in particular to a vermicompost-based yew potted plant suitable for formaldehyde-polluted indoors and capable of efficiently absorbing indoor formaldehyde, and a preparation method and application thereof. Background technique [0002] Formaldehyde has been classified as "a class of carcinogens and teratogenic substances" by the World Health Organization, and excessive formaldehyde is quite common. Especially under high temperature conditions, the volatilization of formaldehyde will double. Before the present invention is made, the simple method that can generally adopt to eliminate indoor formaldehyde is: (1) plant purification technology, green plants can absorb various indoor gaseous pollutants, mainly comprise benzene, toluene, ethylbenzene, xylene, acetone, three Common indoor gas pollutants such as vinyl chloride, formaldehyde, and am...
