1. The pitaya flower is not only ornamental, but also edible. It can be used for making tea, cold salad and soup, and has the effects of clearing away heat, moistening lung and nourishing nutrition. This is Vietnam's dragon tea, and the red dragon fruit planted here is world-famous. The propagation of pitaya generally adopts the method of cutting, and the cutting time is the most suitable in spring. The cut wound is air-dried and inserted into soft and breathable soil, which can take root in about one month, and the seedbed can be transplanted when the root grows to four centimeters. Pitaya is suitable for growing in sunny environment. After two years of exposure and careful care by fruit farmers, it can blossom and bear fruit. This is the flowering flower of pitaya.

Secondly, the flowering time of pitaya is very short, only one night, and it blooms in the evening, and the stem is the largest at 1 o in the morning. The flower of pitaya is big, white and fragrant, in order to attract bees to pick honey trees, and then the flower will wither in the morning and grow fruit. The fruit of the dragon can blossom and bear fruit all year round, and it can bloom ten to 15 times a year. In autumn and winter, the nights get longer. In order to make the pitaya blossom normally, it needs more than 12 hours of light every day, so the farm adopts standard lighting equipment at night to ensure its full photosynthesis, so that it can grow better and the pitaya will grow sweeter.

3. Fruits mature 30 to 40 days after flowering, and the weight of three fruits is 500 to 1 kg. In the second year after planting, there are more than 20 fruits per plant, and in the third year, the fruits are in full bloom, and the yield per mu reaches more than 2500 kg. Fruit farmers will pick ripe pitaya with scissors, put them neatly in baskets, and then send them to processing plants, which can be wrapped and sold after cleaning. Some pitaya will be made into dried pitaya. First, wash the pitaya with clear water. Workers will peel off the shell of each pitaya and put it in the machine. The knife in the machine will cut the pitaya into pieces, then put the cut pitaya in the oven to dry the water, and then put the dried pitaya in the packaging bag to seal it, thus making it into dried pitaya.
