Background
With the rapid development of economy and the improvement of living standard of people, indoor air pollution is more and more serious, and the indoor air pollution becomes the biggest threat to the health of people. Formaldehyde is a main pollutant in indoor air, and seriously harms the health of people due to high toxicity, wide sources and long duration. In recent years, with the continuous improvement of the requirements of people on the surrounding environment, the natural ecological environment is more advocated by people, and the research on the potted plant for purifying formaldehyde in indoor air has become a research hotspot in the environmental field.
The mangrove forest is a unique woody plant community in the coastal zone of the tropical zone and the subtropical zone, is mainly distributed in the intertidal zone of estuary bay, and has important ecological function and great economic and social values. With the development of coastal socioeconomic development, the interference of forest destruction, cultivation, forest digging and catching of economic animals, seawater pollution and the like is increasingly serious, so that the originally few and scattered mangrove forest resources are increasingly reduced.
Numerous studies have shown that mangrove has high primary productivity, fixation of CO2 and release of O2 by plant photosynthesis, reduction of greenhouse effect and purification of the atmosphere, while many mangrove plants also have the function of absorbing radiation, such as roots of seedlings of avicennia marina (Avicenniamarina) Bruguiera (Bruguiera gymnifera), Acanthus ilicifolius (Acanthus ilicifolius), Kandelia obovata (Kandelia obovata) and elaeagnus corniculatus (aegerita), which can enrich 90Sr in large quantities, especially 90Sr seedlings of elaeagnus japonica, with 97.7% of the absorbed 90Sr concentrated in the roots. Meanwhile, many species of mangrove plants are shrubs, root systems are staggered and peculiar in shape, and the mangrove plants are mainly divided into pillar roots, respiratory roots, knee-shaped roots, platy roots, aerial roots and surface roots and have high aesthetic value.
CN101743887A discloses a potted plant process method of mangrove plants, which comprises the following steps: constructing a double-layer flowerpot consisting of a transparent outer flowerpot and a built-in flowerpot, filling tidal flat soil in the built-in flowerpot as a growth substrate, planting the mangrove plant seedlings or intact embryos in the growth substrate, filling artificial seawater into the flowerpot to cultivate the mangrove plant seedlings or embryos, and imitates the sea tide fluctuation rule of half-day tide, artificial seawater is filled and discharged into the flowerpot every day to cultivate and manage the planted mangrove plant pot culture, after the red tree plants grow and develop and developed respiratory roots are formed in the outer flowerpot, the respiratory roots are guided to be molded into a required shape, and the like, the invention successfully transplants the mangrove plant into the room for cultivation and develops into the potted art, combines the function of purifying the indoor air of the mangrove plant and the aesthetic value thereof, plays an important role in creating a healthy and comfortable living environment for human beings, but the survival rate of the potted mangrove plant is low.
CN107691077A discloses a mangrove plant potted seedling protection method, which comprises the planting steps: laying a grid layer at the bottom of the flowerpot, putting soil into the flowerpot, and planting the hypocotyl of the mangrove into the soil; and (3) low-temperature protection: and (4) spraying an antifreezing solution on the trunk of the mangrove seedling. The parameters in the steps of the method have synergistic effect, so that the survival rate of the mangrove in the pot culture is improved. CN102948355A discloses a potting technology for mangrove forest seedling cultivation, which comprises the following steps: 1) selecting a seedling raising land, and selecting a muddy reclamation beach with small wind wave, low salinity and fresh water supply; 2) seedling raising is carried out by a nutrition bag, a seedling raising substrate is filled in the nutrition bag, and the seedling raising is directly carried out on the viviparous mangrove plants by the nutrition bag; 3) the bagged seedlings are transferred to a pot, the bagged seedlings are cultivated for 0.5 to 1 year according to the method of the step 2), the bagged seedlings grow into small seedlings, and the small seedlings are transplanted into a plastic seedling pot for large seedling cultivation; 4) cultivating potted big seedlings, transplanting the small seedlings into a plastic pot, putting the small seedlings in a nursery land for big seedling cultivation, and enhancing water and fertilizer management, shaping and pruning and pest control in the big seedling cultivation process; 5) and (3) outplanting the big seedlings, and culturing the small seedlings transplanted in the step 4) into big seedlings of the mangrove after the small seedlings grow in the plastic nursery for 1-2 years. However, the cultivation method is complex to operate, large in occupied area and not suitable for popularization and application, and living burden of people is increased invisibly.
