Pitaya is a perennial climbing succulent shrub, also known as Lady Enforcers, Fenugreek, Fenugreek and Bawangbian. Its branches are mostly wavy or crenate, dark green to light blue-green, hairless, bony, prickly cones, red rectangular berries, small umbilicus, white pulp and seeds.
Because it has a red coat, the protrusion on the coat is like a flame, which reminds people of Longlin. Therefore, it is named pitaya, which is distributed from Central America to northern South America and widely cultivated all over the world. Hawaii and eastern Australia also have wild ones. It was introduced to China on 1645 and widely cultivated everywhere. There are also wild species in Fujian, Guangdong, Hainan, Taiwan Province and Guangxi, which climb up tree trunks, rocks or walls by air roots.
growing environment
Pitaya is suitable for growing in tropical areas, and it is a tropical and subtropical fruit, which likes light and shade, heat and drought, fat and barren. It grows rapidly in a warm, humid and sunny environment. When cultivated in the open field in spring and summer, it is necessary to water more to keep its roots in a vigorous growth state. Rainy weather should be drained in time to avoid stem meat rot caused by infection with germs. Pitaya can tolerate low temperature of 0℃ and high temperature of 40℃, and the optimum growth temperature is 25-35℃.
Pitaya can adapt to a variety of soils, but it is best to choose neutral soil and weak acid soil rich in humus, which can preserve water and fertilizer. Its stems can also grow on rocks, and its plants are very wind-resistant. As long as they are firmly supported and can resist typhoons, they climb on trunks, rocks or walls by air roots, and are often born at an altitude of 3-300 meters.
