First, tree species selection
Planting trees in the yard is dispensable. According to geomantic omen, plants can be divided into two categories: bad luck and bad luck. There are two criteria for dividing the perpetrators: one is based on whether there is poisonous gas or venom, which has certain scientific basis. For example, some scholars believe that cordate telosma will emit a large number of particles that strongly stimulate the sense of smell at night, which has adverse effects on patients with heart disease and hypertension. The flowers of oleander are poisonous, and the fragrance of flowers makes people sleepy and reduces human function. Tulip flowers have soil alkali, which is easy to fall off when exposed to hair too much. This is a fierce tree and should not be planted in the yard. The other is the shape of the tree, such as "the tree is strange, and its name is ruined by anger", "the tree is hunched over, and its wealth is exhausted", "the tree is like an ox, and it is ill" and so on. All ugly, dignified and abnormally developed trees are fierce. I'm afraid this is a psychological effect or a traditional humanistic aesthetic concept at work. As for auspicious tree, it is determined according to plant characteristics, meanings and even homophones, and people tend to hold this view in real life. For example, Feng Shui scholars believe that 65,438+03 plants such as palm, citrus, bamboo, Toona sinensis, Sophora japonica, Ganoderma lucidum, plum, Ficus microcarpa, jujube, pomegranate, grape and begonia are auspicious plants, while peach, willow, wormwood, ginkgo and cypress are auspicious plants.
Second, about planting orientation
Ancient geomantic classics have some conclusions about this: "Peach poplars are planted in the east, plum dates are planted in the south, elms are planted in the west and plums are planted in the north", "It is unlucky to hang willows in front of the door", "Sophora japonica is in the middle of the door, and there are ghosts behind the house", "Double dates are planted in front of the door" and "bamboo and wood are green in front of the house to make money". From the above conclusions, combined with modern scientific knowledge, we think that some conclusions contain natural scientific knowledge, while others are a psychological need to avoid misfortune. For example, peach trees are planted in the east because the sunrise is the first in the east, willow trees germinate earlier, and peach blossoms are one of the earliest flowering plants in spring, so it is more reasonable to plant them in the east, elm trees are wet plants, and it is more appropriate to plant them in the west when the sun is not afraid. As for the saying that locust trees attract wealth and elm trees exorcise ghosts, there are probably many superstitious elements. Willow should not be planted in front of the main gate, which may refer to willow "easy virtue", which is psychologically unacceptable. For reference, I hope it can be adopted.
