Four major problems of pitaya root system and their solutions

In the cultivation of dragon fruit, the root is the basis of dragon fruit, root problems that is a big problem, and dragon fruit is a shallow root crop, there is no main root, the need for water and nutrients are from the root absorption, root absorption is poor, the late yield and quality is even worse. Let's take a look at the common root problems of dragon fruit with the editor.

1. Rotten root

The root rot of dragon fruit is mainly caused by excessive soil moisture, which should control the watering times, do a good job of drainage in the rainy season, and use some bacterial fertilizer to loosen the soil and improve the rhizosphere environment. Another kind is the root rot caused by excessive acidity of the soil, which can be improved by using organic fertilizer to improve the soil and adjust the pH value of the soil.

2. Base rot

The basal rot of the seedlings is caused by the fact that the wound is not air-dried or is too deeply planted. In this case, the rotten place can be trimmed off, and after the wound is air-dried, the root system can be re-cultivated, and the cuttings only need to be inserted into about 5 cm. Because dragon fruit is a shallow root crop, it is not suitable to plant too deep. And the fruit trees that have been rotting for more than a year are caused by stagnant water in the root system. At this time, the rotten place needs to be scraped off, a little more sterilized, and then covered with mud in a mineral water bottle to let it take root again.

3. The branches are withered and shrunk.

There are two reasons for this: one is root decay, which affects the absorption of water and nutrients in dragon fruit, which makes the plant become withered; the other is the harm of root nematodes, which causes the function of root system to be destroyed after parasitizing the root system. as a result, the aboveground part of dragon fruit gradually weakens and turns yellow, and finally affects the yield. If it is the harm of root nematode, it is suggested that organic fertilizer should be applied to regulate the soil structure of root and inhibit the occurrence of root nematode.

4. Root aging

The main reason is that the root system of fruit trees is corked and aged in advance because of the selection of fertilizer and unreasonable collocation of fertilizer. Therefore, fertilization must be scientific and reasonable, at least twice a year because of organic fertilizer root adjustment, and then according to the different growth stages of fruit trees to supplement nutrients, the roots can be applied phosphorus and potassium fertilizer to promote capillary root germination, as far as possible the use of compound fertilizer with strong destructive power to the soil.

The above is the introduction of the four major problems of dragon fruit root system and their solutions. I hope I can help you. If you want to know more about it, please follow us.
