If you are in a place like Hainan where the climate is warm and there is no need for insulation, the cost per acre will be less than 15,000 yuan.
Planting technology
1. Requirements for environment, soil quality, and temperature
Dragon fruit is a tropical and subtropical plant, resistant to drought and high temperature, and requires soil quality Not high, it can be planted on flat land, hillside, or sandy land, but it is best to choose sandy loam soil with rich organic matter and good drainage performance for planting. Areas where the temperature in winter is lower than 8℃ for a long time are generally not suitable for planting. 2. Planting methods
There are many ways to plant pitaya, some climbing walls and some under sheds, but column cultivation is the most common, with low production costs and high land utilization. The so-called pillar style is to erect a cement pillar or wooden pillar, plant 3 to 4 dragon fruit plants around the pillar, and let the dragon fruit plants grow upward along the cement pillar.
3. Planting specifications and seasons
110 columns (specification 2.5 meters × 2.5 meters) can be established per mu of land. If 4 fruit seedlings are planted in each column, 400 trees can be planted per mu. Multiple plants can greatly improve land utilization. Dragon fruit can be planted all year round. Because its root system likes to be breathable, it should not be planted too deep (generally covering about 3 cm of soil). The soil should be kept moist in the early stage, otherwise it will not be conducive to its growth.
IV. Field Cultivation and Management
Pytaya begins to flower and bear fruit about 14 months after planting. It is a high-efficiency crop that flowers and bears fruit at the same time. Fruit production occurs from April to November every year. It can be harvested 30 to 40 days after flowering. The weight of a single fruit is generally 500 to 1,000 grams. The plant produces more than 5 fruits every year and enters the fruit-rich period in the third year.
1 Fertilizer should be applied frequently and lightly: Due to the long harvest period of pitaya, organic fertilizers must be applied heavily, and nitrogen, phosphorus, and potassium compound fertilizers must be applied in a balanced and long-term manner. During the flowering and fruiting period, additional potassium and magnesium fertilizers should be applied to promote the accumulation of sugar in the fruits and improve the quality and sugar content.
2 Timely topping: When the branches grow to about 1.3 to 1.4 meters, they should be topping to promote branching and allow the branches to droop naturally, accumulate nutrients, and bloom and bear fruit early.
3 Prune branches: Branches that have produced fruit should be cut off after harvesting each year to allow them to grow new branches to ensure fruit production in the coming year.
4 Prevention and control of pests and diseases: It has been observed that dragon fruit basically has no special pests, but it is susceptible to damage from snails and ants in the seedling stage, which can be prevented and treated with insecticides; in high-temperature and high-humidity seasons, it is susceptible to diseases and branch plants appear. If the tissue is partially necrotic and has mildew, the use of fungicidal pesticides can achieve good results.
