How to manage the dragon fruit field?

The dragon fruit begins to blossom and bear fruit about 14 months after planting, and can blossom 15 times a year. The fruit period is from April to November, and the fruit can be harvested in 40 days after Xie Hua. The weight of a single fruit is generally 500ml / 1000 g. In the second year after planting, there were more than 20 fruits per column, and the third year entered the full fruit period. if the management level was high, the yield of 667m2 could reach more than 2500 kg, and the early fruit yield was good. Due to the long harvest time of fruit, organic fertilizer should be re-applied every year, and nitrogen, phosphorus and potassium compound fertilizer should be applied evenly for a long time. Potassium and magnesium fertilizers should be added during flowering and fruiting period to promote sugar accumulation and improve fruit quality. Keep the soil moist during the fruiting period, and the tree plate is covered with grass or mushroom residue. When the weather is dry, irrigate once every 3-4 days. The fixed pruning branch should maintain single branch growth before climbing to the top of the cement column, and after growing to the top of the column (1.3-1.4 meters), it should be coring, promote branching, and let the branches droop naturally, accumulate nutrients, and blossom and bear fruit early. The natural germination power of dragon fruit with good growth is higher, generally 5 new branches can be produced from each branch, in order to increase or decrease the strong fruit branches, during the vegetative growth period every year, each branch can leave 3 branches with strong growth according to the growth situation; during the reproductive growth period, in order to ensure the nutritional requirements of fruit development, all the newly germinated branches should be removed. When interplanting and artificial pollination to grow red meat type dragon fruit, it is necessary to plant about 10% of white meat type dragon fruit. Mutual pollination among varieties can significantly improve the seed setting rate. Artificial pollination should be carried out in cloudy and rainy weather. Before the flowers bloom in the evening or before the flowers are closed in the morning, the pollen can be directly applied to the female flower stigma with a writing brush to increase the fruit setting rate. Huolongguo has a long flowering period and strong flowering ability. It will blossom from May to October, with an average of 2.7 buds per flowering season. After pollination and fertilization is normal, the withered flowers can be cut off by ring carving (retain the sepals below the stigma and ovary). Fruit thinning began when the transverse diameter of the young check reached about 2 cm. Each branch left a young fruit with full development, bright green color, no damage and deformity, and a certain growth space, and the rest were thinned to concentrate nutrients and promote fruit growth. Fruit bagging should be bagged with waste newspapers or Kraft paper bags before the pericarp changes color, so as to keep the pericarp evenly colored and prevent birds, wasps and other bites, wind scraping and sun exposure, so as to improve the commodity value. The growth period of timely harvested fruit varies with production season, buried location and variety. Generally, it can be harvested about 45 days after flowering. Harvesting too late will not only cause fruit cracking, but also cause the local color of the pericarp to blacken, affecting the commodity value. Fruits that need to be stored for a long time or transported over a long distance should be harvested before softening and darkening. Click to see more dragon fruit planting techniques
