Morphological characteristics:
Plants have no main roots, and lateral roots are widely distributed in shallow soil. At the same time, there are many aerial roots to climb and grow. Rhizomes are dark green, stout, 7 meters long, 10- 12 cm thick, and have three edges. The edge is flat and the edge is wavy. Climbing roots grow on stem nodes, which can climb on other plants. There are three edges, and there are small thorns in the depression of each stem node. ?
Pitaya branches and leaves:
Because of its long-term growth in tropical desert areas, its leaves have degenerated, and its photosynthetic function is borne by its stems. Inside the stem is a large number of parenchyma cells filled with viscous liquid, which is beneficial to absorb as much water as possible in rainy season.
