Sharing Techniques of Growing Dragon Fruit Brings a Good Harvest

Dragon fruit has contributed significantly to Vietnam’s fresh fruit export turnover in recent years. Here, I would like to introduce to you Technique of planting dragon fruit trees as well as how to take care of the tree to stay healthy. Farmers do not rush to ignore this article.

Technique of planting dragon fruit trees

Things to know before planting dragon fruit.

Dragon fruit belongs to state-rooted plants, eats dry and loves light, so the tree should not be blocked by more than 30% of sunlight, and the area for planting must be well ventilated and not flooded. Irrigation water must not be contaminated with salt or alum.

To prepare the soil for planting we need to pay attention to what kind of soil we have, whether it is high or low land. and for each type of soil, we prepare as follows:

– For high soil: This type of soil is relatively simple to prepare: Measure the size and dig a hole into the pillar (how to dig, see below). After burying the pillar, dig around the pillar 10 – 20 cm deep, 1.5 m in diameter, fertilize with rotting manure, phosphate and if necessary, add Trico and then cover with top soil after 1 to 2 week then order hom.

– For low land: As the type of soil close to the water level, we need to dig ditches. The soil that is accreted when planting must be at least 40 cm above the water surface in the ditch when the water level is highest. Because when the water level is not carefully prepared, the plants will be waterlogged, causing yellowing, leading to no yield.

Density of planting dragon fruit trees

It is recommended to plant dragon fruit with an amount of 1,100 pillars/ha, equivalent to about 3 mx 3 m/tree. As for why it should look like a dragon fruit with such a distance, it is the same as above. It is a light-loving plant, so when planted thickly, the lack of light will result in small, unsightly fruits leading to poor yield, low cost… in general, there are many consequences.

Place 3 – 4 cuttings around the support tree (pillars), attention should be paid to: Place cuttings 0 – 5 cm shallow to avoid root rot due to moist soil. Put the flat part of the cutting against the edge of the pillar so that the cuttings will take root and quickly cling to the post.

Choose a pillar to plant a dragon fruit

Why you need to choose the pillar, you probably already know. Because it is a tree that needs to be attached to a pillar, the selection of a pillar needs to be considered first. Besides, the cost of the pillar accounts for the highest percentage initially.

The pillar is usually 2.5 – 2.7m long, with a diameter of about 25cm, after being buried, the height is about 2m. Currently, the trend of people is to lower the pole, the height of the pole is about 1.6 m to 1.8 m, the diameter is about 15cm for convenient care and harvesting, especially to support expenses. initial fee. People can choose concrete or wooden piles depending on which is more convenient. If you choose wood, you must choose a wood that can withstand the sun and rain, not rot, for example: Xylia dolabriformis Benth, Lien Xyle, Ca Coc, Black Star …

Preparation of cuttings of Thanh Long varieties

Currently, the most effective method is planting by cuttings. Every year, pruning creates an abundant source of cuttings, but for good growth, it is necessary to choose branches with the following standards:

The cuttings are 40-60cm long, choose straight, big, strong branches, no pests and diseases, The thorny eyes must be good, slim, good budding ability, about 1 year old branches are the best. The bottom of the cuttings (3 to 5cm long) cut off the outer flesh, leaving the core, the purpose is to avoid rotten cuttings. We should take cuttings before planting in the shaded area until the branches take root and sprout new shoots, then plant them to choose the best trees and, importantly, later your dragon fruit will be. 100 plants like 1. And to keep the cuttings up evenly, people should dip the cuttings in a fungicide solution, such as Benlate C, concentration of 0.1% within 5 minutes.

Time to plant dragon fruit

Dragon fruit can be grown all year round, but we should plant it in April-May or in October-November of the solar calendar. Each time has different advantages and disadvantages:

Planted in October-November, the source of cuttings is abundant due to the time of pruning. The advantages of this stage are: For lowland areas, the risk of flooding is avoided. However, the downside is that it is necessary to pay attention to watering and moisturizing the tree in the next sunny season because the tree is not large enough to be able to withstand drought.

The most suitable time to plant dragon fruit is in the last months of the year

Planting in April-May, the downside is that during this time, dragon fruit is flowering season, so cuttings are lacking. However, this is the beginning of the rainy season, so the tree is easy to grow. In areas with a lack of irrigation water should be planted at this stage.

How to Fertilize the Dragon fruit every year

For the dragon fruit tree to grow well, we can fertilize in 2 ways

Fertilize in batches 3-4 times a year (Suitable for business plants).

Fertilizer divided into several times (High efficiency with builder),

In the first year, chemical fertilizers are mixed with water and irrigated or sprayed on the whole stem for rapid growth. In the following years, spread fertilizer around the base and then lightly water the fertilizer to dissolve and soak into the ground with the following formula.

When dragon fruit trees are young (under 3 months) after 2 weeks of planting (with fully rooted plants) can use DAP + Urea or NPK 20-20-15 or 16-16-8 watering, dose 20 -30g/head, Watering 10 days/time

With plants 3-12 months, people use Urea + DAP or NPK 16-16-8 or 20-20-15 water 30-50g/pillar, 15 days/time depending on the type of soil and increase with the age of the tree.

The basic construction phase: lasts only 1 to 2 years. The total amount of fertilizer commonly applied is 30 kg Urea + 20 kg NPK (16-16-8)/100 cylinders/year.

In addition, it is necessary to add micronutrients by spraying or applying root fertilizer so that the seedlings will grow very strongly at the early stage and will give fruit soon.

Business stage: from the 3rd year onwards, when the tree has begun to give stable fruit, people need to pay attention to the amount of potassium to make the fruit more juicy and firm and shiny. Should be divided into 4 times of fertilizing plants in the months of November- 2-5-8, the amount of fertilizer is about 350-500g/plant and provides 15-50 kg of manure.

Each stage of dragon fruit development will have its own requirements for the ratio of fertilizers

Particularly, manure only needs to be applied once after pruning (November) to add organic matter and keep the soil moist.

1st time: October – 11: This period needs to focus on the amount of nitrogen and phosphorus for the plant to grow and flower for the next crop.

2nd time: February 2-3 This stage is similar to phase 1 but we should add more potassium but less. In order to stimulate dragon fruit to flower quickly, increase the gloss of the peel, size and hardness of the left ear, farmers can use foliar fertilizers sold on the market such as 10-60-10….

3rd time: May-June We should choose NPK fertilizer lines with content such as 20-20-15, 15-15-15, 16-16-16…or a single fertilizer with equivalent ratio.

The 4th time: August-September This period we pay attention to applying high amounts of potassium such as 15-5-20, 15-5-25… if you can add potassium sulphate, the better.

Watering the dragon fruit tree

Dragon fruit is a good drought-loving and hot-loving species, but prolonged drought will make the tree lose strength and reduce the ability to flower and fruit because the formation of new branches is less, prone to atrophy and yellowing of branches. Especially if the fruit has beans, it is also small and not beautiful.

Dragon fruit is a fruit tree with very good drought tolerance, but people still need to provide the necessary moisture for good growth.

Depending on soil moisture, the irrigation time is changed from 3 to 10 days/time. If planting dragon fruit with flower treatment with lights, they have to actively water in the dry season, usually watering in the morning according to the above time.

Hopefully with the information we have gathered in this article. Planting and taking care of dragon fruit trees is no longer a difficult thing for farmers. Thank you for your interest in following the article.
