How to plant dragon fruit trees

The suitable soil for planting dragon fruit trees is sandy loam and loam with rich organic matter and good drainage, and the pH value is 6-7.5. Then, according to the cement column line to open the ditch to make the bed, plant the seedlings at the foot of the cement column, the root is buried 3 cm to 5 cm, and tie the seedlings to the cement column with a rope. After planting, do a good job of fertilization and watering.

1. Soil: the dragon fruit tree is resistant to drought, high temperature and light, not resistant to frost and cold injury, and does not have strict requirements for soil quality. it is best to choose sandy loam and loam with rich organic matter and good drainage, and you can choose cultivated land or sunny sloping land. the soil pH value is 6-7.5, which should not be planted in areas where the temperature is lower than 8 degrees for a long time in winter.

2. Soil preparation: there are many ways of planting dragon fruit trees, including wall planting, bridge planting and shed planting, among which column planting is the most common. The so-called column type is to set up a cement column or wooden column and plant 3 or 4 dragon fruit plants around the column to let the dragon fruit plant grow upward along the cement column. According to the cement column row to open the ditch to make the border, the border surface width is 1.52m, the drainage and irrigation ditch and the working road width is 0.5m, combined with the soil preparation and burying farm manure 300kg to 500kg for soil improvement.

3. Planting: four seedlings are planted under the foot of a cement column, planted in four directions close to the foot of the cement column, and the roots are buried 3cm to 5cm, and then the seedlings are tied to the cement column with a rope. The suitable planting density is 2m × 2m row spacing, that is, 166pillars are planted per 667m2, 3 seedlings are planted around each column, and 498seedlings are needed per 667m2.

4. Fertilization: young trees (1-2 years old) mainly apply nitrogen fertilizer, while mature trees (more than 3 years old) mainly apply phosphorus and potassium fertilizer to control the amount of nitrogen fertilizer. Fertilization should be carried out in the spring shoot germination period and fruit expansion period. Fertilizer is generally formulated with withered cake dregs, chicken manure and pig manure at 1:2:7, with 25 kg organic fertilizer per plant per year.

5. Watering: water should be watered more in spring and summer to keep the soil moist. Irrigation should not be immersed for a long time, nor should it be often watered from beginning to end. Drainage should be timely in overcast and rainy weather and water should be controlled in winter. Immersion irrigation will make the root system in a state of long-term hypoxia and die, and water will cause uneven humidity and induce erythema (physiological lesions).
