Pitaya is also known as Qinglong Fruit (Asia), Pitaya (most English-speaking areas), Pitaya (Mexico) and Red Dragon Fruit. And various trade names, such as "Xianhoney Fruit" and "Yulong Fruit", vary with the listing of commodities. Pitaya and Seleniereus Meja-lantos, belonging to cactus family, are common fruit types in Costa Rica, Guatemala, Barama, Ecuador, Cuba, Mexico and Colombia in Central America.
In Asia, this species is mainly distributed in Taiwan Province Province and Viet Nam, and was brought in by the Dutch and the French during the colonial period. Apart from the place of origin, this fruit is mainly sold to the United States and Japan. In terms of consumption concept, it is a green fruit and a nutritious food with certain curative effect.
Pitaya is a perennial vine of Fenugreek in Cactaceae, and it is a new fruit with good health care function. Native to the tropical rain forest area of Central America near the equator in the western hemisphere. This determines its biological characteristics: 1. Heat resistance and low temperature resistance. It can withstand 40-50℃, but there will be different degrees of cold damage below 8℃, and it will freeze to death below 0℃ It doesn't come from dry and hot desert, but from tropical rain forest, so "nature" doesn't like drought but likes humidity. Its roots are not resistant to water immersion, not to water, but to hypoxia. Therefore, it is decided that its cultivation characteristics should be shallow planting rather than deep planting, which is convenient for drainage. It is best to leave a loose, breathable and moist cover on the surface, such as litter or growing weeds, to imitate the growth conditions of their ancestors, so that aerial roots can meander and stretch near the surface to absorb water and fertilizer.
Due to the origin, planting environment, market sales and other factors, it should be said that there are not many pitaya in Chinese mainland. However, all major supermarkets have sales, which is more than enough to meet personal needs.
