Cultivation techniques of dragon fruit

Dragon fruit is a long-lived plant, it can survive hundreds or even thousands of years. And dragon fruit taste sweet, high output, sales are also very good. So as such a popular fruit, how is it cultivated? What do you need to pay attention to? Let's take a look at it together.

Cultivation techniques of dragon fruit

The main results are as follows: 1. Pitaya is a tropical plant, which likes light and shade, fertilizer and barren. its stem can also grow on rocks, and the plant is extremely resistant to wind. As long as the bracket is firm, it can resist typhoon, generally planting about 300 plants per mu. There is a cement column 15 cm square and 2 meters high in the middle of every three trees as a support, that is to say, three trees are planted around a cement column.

2. The row spacing of the cement column is 2.2 meters × 2.2 meters on the hillside and 2.5 meters × 2.5 meters on the flat ground. Fire dragon fruit to farm manure-based, try not to apply chemical fertilizer, before planting, each plant is about a load of rotten pig and cow manure, mix well with the soil and then plant. First plant the cement column, and then plant the seedling, which is about 10 cm apart from the column, so that it grows up next to the column.

3. Pitaya can be adapted to all kinds of soil, and the soil with high salt content can also be planted, but it is better to use neutral soil and weakly acidic soil with more humus, water and fertilizer. In order to make it grow vigorously after planting, calcium magnesium phosphate fertilizer and compound fertilizer should be applied in the later stage. The amount is determined according to the plant size. The cement column is 2 meters high, 40 centimeters into the ground and about 1.6 meters high. When making the cement column, cross-punch at the top 10 centimeters of the column for use.

4. After the column, two steel bars about 70 cm long are pierced into a cross, and the tires of the old bicycle are placed on the cross steel bar. When the dragon fruit plant grows to be parallel to the cement column, the head is cut off. At this time, the plant will not grow up. A lot of horizontal branches and stems will be sent out laterally, drooping down, and the cross tire is used to support the drooping leaf stem and fruit. If used for bonsai, the columns are short, with corrosion-resistant wooden columns or steel bars, etc.

Fertilization skills of dragon fruit

1. The fertilization of dragon fruit should be based on the principle of sufficient, small amount and multiple times. Young trees mainly apply nitrogen fertilizer, so as to promote the growth of trees. Adult trees mainly apply phosphorus and potassium fertilizer to control the amount of nitrogen fertilizer.

2. Fertilization should be carried out in the period of shoot germination and fruit expansion in spring. the fertilizer is generally formulated with withered cake residue, chicken manure and pig manure at 1:2:7, with 25 kg organic fertilizer per plant per year. Or in July, October and March of each year, 1.2 kg of cow manure compost and 200 g of compound fertilizer were applied to each plant.

3. After each batch of young fruit was formed, 0.3% magnesium sulfate, 0.2% borax, 0.3% potassium dihydrogen phosphate was sprayed outside the root to improve the fruit quality. Due to the long harvest time of dragon fruit, organic matter fertilizer should be re-applied, and nitrogen, phosphorus and potassium compound fertilizer should be applied evenly for a long time.

4. Completely use fertilizers with high nitrogen content in pig and chicken manure to make the branches thicker, dark green and brittle, easy to break in strong wind, large and heavy fruit, poor quality, low sweetness, and even sour or salty taste. Therefore, potassium fertilizer, magnesium fertilizer and bone powder should be applied during flowering and fruiting period to promote fruit sugar accumulation and improve fruit quality.

Water management of dragon fruit

The dragon fruit grows rapidly in a warm, moist, well-lit environment. The soil moisture of the whole garden should be kept during the seedling growth period. The root system should be watered more in spring and summer to keep its root system growing vigorously. During the period of fruit expansion, the soil should be kept moist to facilitate fruit growth. Irrigation must not be immersed for a long time, and do not often drench water from beginning to end. Immersion irrigation will make the roots in a long-term anoxic state and die, and watering will cause uneven humidity and induce erythema. Drainage should be carried out in time in rainy weather so as not to cause stem and flesh rot caused by germs. Water should be controlled in the garden in winter to enhance the cold resistance of the branches.

The whole pruning technique of dragon fruit

The main results are as follows: 1. after the pruning and planting at the seedling stage survived, the plant climbed along the cement column. at this time, the side branches sprouted during the seedling growth, one strong upward branch should be retained, and the other side branches should be cut off in time, which is beneficial to concentrate nutrients for the strong branches to climb up quickly.

2. When the plant grows to 1.5 meters high, it can divide more than 3 natural drooping branches, and when the branches are mature and in the period from April to November, these drooping branches will have a chance to blossom and bear fruit. The growth potential of the upper branch is usually larger than that of the middle and lower branches, which may be caused by the top advantage, but the upper branch is not easy to be bound because of its high position, although its growth potential is strong, but the tissue mechanical strength is poor, and it is often easy to be broken by the wind. The upper branches can gradually adopt the methods of bracing, pulling, hanging and binding, and gradually let them droop to reduce wind damage after the branches mature and begin to blossom.

3. After fruiting, each plant can arrange the branches of 2 to 3 as fruiting branches, and the other branches of 1 to 3 can erase the buds or flowers, reduce the growth angle of branches, promote their actual vegetative growth, and cultivate them as strong preparatory fruiting branches.

After reading the article sorted out by the editor above, I believe you have a certain understanding of the cultivation techniques and matters needing attention of dragon fruit. When planting dragon fruit, we must pay attention to its soil environment, so as to ensure its later rising trend. Fire dragon fruit as a high-yield fruit, as long as we take good care of it, I believe it will bring good benefits.
