How to increase the sweetness of the planted dragon fruit

Most of the dragon fruits on the market are big and sweet, but the fruits planted by some growers are not as good as expected. Today, let's take a brief look at how the dragon fruit is sweetened and increased.

If you want to grow dragon fruit with sweet export and huge fruit, you can improve it from the following aspects.

1. Moderate and reasonable fat gain

The demand for nutrition during the growth period of dragon fruit is relatively high, so it is necessary to ensure reasonable and effective fertilizer supply in order to make dragon fruit produce large and sweet fruit. The application of good fertilizer can ensure the healthy development of fruiting stem, which is the basis of good fruit. In fertilization, nitrogen, phosphorus and potassium are mainly used as complete fertilizer. In order to keep up with nutrition, trace elements can also be added. Circular trenches can be dug around the roots of the plant at a certain distance, fertilized or fertilized in the water and poured on the soil of the roots. Foliar spraying and fertilization can also be carried out when the dragon fruit blossoms and bears fruit to promote the accumulation of sugar in the fruit.

2. Improve the soil condition.

Before planting dragon fruit, we should first prepare the planting land, where we choose a slightly acidic soil with normal thickness and fertility, soft and suitable. If the soil quality needs to be improved, shallow ploughing can be carried out to increase the amount of microbial fertilizer.

3. Rational irrigation

Keep the soil moist during the sprouting and fruiting period of dragon fruit. However, water can not be drenched or immersed for a long time, which will cause uneven humidity and induce erythema; too much stagnant water will lead to hypoxia and death of the foundation. Water should be controlled in the garden in winter to enhance the cold resistance of the branches.

4. Adjust the temperature balance

As a tropical fruit, dragon fruit is very resistant to high temperature, but in order to produce good fruit, it needs to provide a better growth temperature. We maintain the temperature at 25: 35 ℃ during its growth period and 15 ℃ at night. Pitaya stops photosynthesis at night and begins to breathe, which consumes photosynthetic substances. The temperature difference between day and night will inhibit the respiration of dragon fruit, resulting in a decrease in its nutrient consumption and an increase in its sugar content. We can use this to increase the sweetness of the fruit.

5. Regulation of other factors

Ensure that the dragon fruit gets sufficient light and improve the overall permeability. The flower and fruit thinning of dragon fruit was carried out in the flower and fruit stage to prevent the amount of flower and fruit from exceeding the bearing range of dragon fruit plant. Get rid of all the weeds that are robbed of nutrition. Finally, do a good job in the prevention and control of diseases and insect pests.

The above are several requirements on how to increase the sweetness of dragon fruit. I hope you will take good care of the plant during the planting process, so that you can grow a good dragon fruit.
