Background
Horticulture therapy is an adjuvant therapy method that involves the physical contact and use of horticultural materials to maintain plants or potted plants and gardens and to contact the natural environment to relieve stress and restore mental well-being. Horticulture therapy is currently used in medicine for care and rehabilitation, such as in psychiatric institutions, nursing home institutions, centres for elderly and children, medical institutions or communities.
With the development of horticultural therapies, the research on the influence of plant volatiles on human has been extensively and deeply studied. It has been shown that plant volatiles can improve the physical and mental health of humans. Wherein, the short plants have relatively low requirements on the cultivation environment, and can be widely planted in indoor balconies, workplaces, rehabilitation environments, spacecraft and submarines and other places. The aroma of some medicinal and edible dwarf plants has been shown to have the potential to improve mood or sleep, such as rosemary, lavender, and the like.
However, the generation and release of plant volatile matters are greatly influenced by the surrounding environment, and the release of the plant volatile matters can be influenced by the change of environmental factors such as temperature and humidity, so that the effect of the horticultural therapy is influenced. Meanwhile, the collection of the volatile matters of the experimental plants is difficult, the plants are difficult to be ensured to keep the same volatile matter release state in the actual variable environment, and the experimental results are possibly influenced greatly. Therefore, it is necessary to ensure that the short plants are in a proper and stable growing environment, so as to ensure the normal growth of the plants, promote the stable release of plant volatile matters, and simultaneously carry out gardening intervention and sampling collection based on olfactory stimulation.
