It is now the last month of 2018, and the temperature is getting colder and colder. Many growers are also in the busiest season of the year, and dragon fruit is one of them. This period of time is also the harvest time of the last batch of dragon fruit, and it is also a time when we need to focus on management. So how to plant dragon fruit in winter? The following editor brings the key points of winter management of dragon fruit, let's have a look!

1. Build the shed in time

The dragon fruit planted in the greenhouse must be well covered in winter. Mainly according to the temperature, when the average temperature of day and night is less than 20 degrees, it is necessary to build the shed in time. To prevent the temperature is too low to cause harm to the growth of dragon fruit, especially for some fresh shoots, serious can lead to death. Covering the shed can effectively improve the surrounding temperature, which is conducive to the development of young shoots and the harvest of the last batch of fruits, but we should also pay attention to the humidity in the shed and open the shed for ventilation on sunny days.

2. Apply overwintering fertilizer

After harvesting the fruit, spray the overwintering fertilizer in time to improve the soil fertility, supplement nutrition for the dragon fruit tree and restore the growth of the fruit tree. Ensure that the dragon fruit trees have sufficient nutrition accumulation to promote the sprouting of fruit trees in the second year. It can also improve the resistance of fruit trees, enhance the ability of cold resistance, and promote successful overwintering. When applying overwintering fertilizer, we should pay attention to control the application amount according to the planting area, ensure adequate nutrition and prevent fertilizer damage to fruit trees at the same time.

3. Clear the garden in time

After harvest and fertilization, the weak growth and pest branches of the fruit trees should be cut off, and then the branches and fallen flowers and fruits should be taken out of the orchard for burning and deep burial treatment. Then the whole garden was sprayed with disinfection insecticides to destroy the overwintering places of diseases and insect pests, reduce the number of pathogens and eggs, and reduce the incidence of diseases and insect pests. Finally, the fruit trees were smeared with Songer film and other substances to improve the disease resistance and cold resistance of fruit trees. Prevent diseases and insect pests from harming the lower stem of the plant.

4. Postpone pruning

It is not suitable for pruning in winter. We should try our best to do pruning in early spring. Because of the low temperature in winter, the new buds may be damaged by low temperature after pruning. And delaying the pruning time can also improve the nutrient accumulation of the tree and help to avoid diseases and insect pests caused by wound infection due to pruning. Therefore, we should prevent mechanical wounds in the trees in winter, affecting the growth of dragon fruit trees.

5. Pest control

The above four points have the effect of pest control, although the winter temperature is low, but poor management, there will be a variety of diseases and insect pests. Therefore, in winter, we also need to do a good job in the prevention and control of various diseases and insect pests to prevent diseases and insect pests from affecting the overwintering of dragon fruit, resulting in reducing the economic benefits of planting. In addition to strengthening the management, it is also necessary to spray and disinfect the orchard regularly, and corresponding measures should be taken in time to prevent the spread of the disease and expand the affected area.
