Cactus, Jin Hu.

English name is Golden barrel, golden cactus.

Origin and habit:

Jinhu originated in the desert area of Mexico and has been introduced and cultivated in the north and south of China. Jinhu likes sunny days and fertile sandy loam with good permeability. In hot summer, it is necessary to properly shade the light to prevent the sphere from being burned by strong light. Sunlight is needed after planting, but it can still be properly shaded in summer. The overwintering temperature is kept at 8- 10℃, and the basin soil is kept dry. It grows faster in fertile soil and where air circulates. It is advisable to change pots once a year in cultivation. It is easier to germinate by sowing and breeding.

Cactus and succulent plants have their own names-"lazy plants". This kind of plant cultivation does not need much care and nursing, and hydroponic cactus is easier to maintain. Because cactus grows in strong sunlight, it is particularly resistant to ultraviolet rays.

Cactus known as the "oxygen bar" at night. Most cacti breathe in cool and humid nights. When breathing, inhale carbon dioxide and release oxygen. Therefore, putting a fairy grass indoors is tantamount to adding an air freshener, which can purify indoor air. Therefore, it is also an ideal flower for indoor night decoration.

Jinhu is a good radiation absorption plant, and it also has a good absorption effect on xylene and toluene released by computer monitors and printers.

Jinhu is rich in symbolic meaning and cultural connotation: First, the sphere of Jinhu is green, covered with golden thorns, with golden wool at the top, which is very beautiful and rich. Cultivate into a large specimen ball to show the emperor's spirit, and use it to decorate hotels, shopping malls, homes and other places, showing resplendence. Second, Hu Jin can ward off evil spirits. In Japanese, the original "Goldfish Tiger" and "Fish Tiger" of "Jin Hu" refer to a fierce sea crystal "anti-halberd bird". Fishermen go out to sea, ships will crash and people will die. Out of fear, people gradually upgraded the "fish tiger" to a totem, and its patterns can often be seen in Japanese temples. "Jin Hu" is also regarded as "fierce" because of its prickliness and hardness, so it is "fierce"
