Planting advantages Compared with many tropical and subtropical fruits, dragon fruit has very obvious advantages, good market prospects and high economic benefits. It will become a sunrise industry that boosts the development of characteristic agriculture and promotes farmers' income. Representative of green fruit. The dragon fruit has gradually become popular with the good image of green fruits, thus stimulating market consumption. It turns out that dragon fruit is a pollution-free, environmentally friendly fruit that is ideal for green cultivation. Pitaya skin has a layer of waxy, protective effect. After being stored at room temperature for 1 month, the flavor does not change. If stored under refrigeration, the shelf life is as long as 2 months. These characteristics have determined that dragon fruit is a fruit that is extremely resistant to storage and transport. The advantages of Nanguo Beiyun are more obvious than litchi, longan, and mango. Most fruits only have a fruity fruit once a year, and they are concentrated on the market, but the dragon fruit is the opposite and the production period is very scattered. From May to November, 6 to 8 times of flowering, 6 to 8 batches of fruits, only 35 days from pollination to maturity, listing for up to six months, is very conducive to a balanced listing. Suitable for sightseeing and cultivation. Dragon fruit is not only a unique fruit shape, but also huge flowers, length 20 to 30 cm, corolla diameter of about 20 cm, commonly known as "Overlord Flower." Every year from May to November, dragon fruit blooms in full bloom at night, and the white and huge flowers make the orchard a sea of ​​flowers. The dragon's fleshy stem has no leaves, and the green fleshy stem has red and red spherical fruit. The unique horticultural appreciation is unmatched by other fruit trees. Dragon fruit can also be planted in flower pots, becoming a newcomer to the family's balcony for flower cultivation and fruit appreciation. Rich in nutrition. Dragon fruit is one of the most striking species in the cactus fruit family, with a peculiar appearance, bright and attractive skin, nutritious fruit nutrition. Studies have shown that vitamin C and anthocyanins in pitaya have the effect of anti-aging and reducing the incidence of heart disease and cancer; the fruits, flowers and stems of dragon fruit are rich in high-quality vegetable protein and heavy metals in the human body. Pollution has a clear detoxification function; medical experts also found that pitaya has hypoglycemic, hypoglycemic, lower blood pressure, prevent arteriosclerosis and other health effects; In addition pitaya rich in water-soluble dietary fiber also has laxative effect . The dragon fruit flower not only has a high ornamental value, but also is a kind of heat and detoxification diet. Rack and plant management The planting density of dragon fruit is closely related to the scaffolding method. The density of different scaffolding methods is not the same. The majority of farmers can choose according to local conditions. Single column cultivation method. Column 1.95 meters high, 0.4 meters into the ground, 1.55 meters away from the ground, 5 cm away from the top of the column set aside two holes for interspersed with 12 mm steel bars, forming a cross-support round frame, used to support dragon fruit tied on the shelves Backwards sagging stems around the circular support. Pillar spacing is 1.72.3 meters, and 170 acres are planted. Three to four seedlings are planted under each pillar and 510 seedlings or 680 mu are required. It is the best cultivation method at present. Horizontal scaffolding method. Height 1.6 meters, width 1 to 1.5 meters, distance between scaffolds 1 meter, on both sides of the scaffold every 0.6 to 0.8 meters a bamboo bar used to support the binding of the stems on the shelves, with wire or bamboo rack Build a horizontal scaffolding. Mu planting 666 ~ 888 strains. Single line support colonization method. A support line was set up with steel ropes or steel pipes and bamboo woods. The planting seedlings were planted under the line. The plant spacing was 0.4-0.6 meters, spacing was 2.3 meters, and 580 acres were planted. Planting pays attention to several issues. One is improper planting. After the dragon fruit seedlings were planted, the soil was buried too deeply, causing the roots to be air-tight, which made the dragon fruit grow slowly or die out. The correct method is to plant a shallow plant and cover the roots with crop straw, plant grasses or plant weeds for green coverage in the whole park. The second is unreasonable scaffolding and extensive management. Due to the lack of management and inspection of growers and random arrangement, the pruning of dragon fruit after being put on shelves is unreasonable, resulting in excessive germination, excess nutrient growth, and reduced fruiting rate. The correct method should be a single-column method of planting, so that the meat stem of dragon fruit after the stent droop naturally, inhibiting its vertical growth advantage, can promote fruiting. At the same time, only 8 to 10 branches per plant are removed, excess shoots are removed, and good plastic trimming is a guarantee of high yield. The third is the lack of artificial pollination technology. Dragon fruit self-flowering rate is not high or unstable, must be matched with pollination varieties, artificial pollination, dragon fruit blossoming and full guarantee. Flower and fruit management techniques. In addition to corolla and stigma. After 3 to 6 days of flowering, there will be a distinct isolation zone between the fruit and the corolla. The corolla and stigma should be removed in time. Otherwise, the corolla rot will affect the fruit growth. The rot of the stigma root will cause worms in the umbilicus and the color will be dull. (Normal is lavender). The method is to hold the fruit in one hand, and the other hand to hold the sagging crown to force the next fold, the corolla and the fruit will break open, and then use the same method to remove the stigma. Fruit bagging. Bagging can not only reduce pests and diseases, prevent pesticide and dust pollution, but also prevent bird damage, increase fruit brightness, and increase sales. It is best to use a colorless, transparent plastic bag for fruit bags, and to bag when the fruit begins to turn red.
