What are the cold-protection and overwintering measures for papaya? A full analysis of the latest methods

Papaya is a tropical fruit tree that likes high temperatures but fears cold frost. In southern regions it often suffers freeze damage, and in severe cases the plants die. Therefore, adopting cold-protection and freeze-resistance measures during cultivation is extremely important. Now let's take a look at the detailed introduction below.

1. Pay attention to overwintering fertilizer

Before winter arrives, apply 15-20 kg of organic fertilizer mixed with decomposed human and livestock manure and plant ash to each plant, with an appropriate addition of 1-2 kg. At a distance of 80-100 cm from the main trunk, dig a ring-shaped trench 20-30 cm deep and 30-40 cm wide, mix the fertilizer with the soil that was dug out, and backfill it into the trench, or use the method of one layer of fertilizer and one layer of soil. After fertilizing, cover the tree disk with rice straw to raise the ground temperature so the root system can overwinter safely.

2. Bundling and whitewashing

Before winter arrives, wrap the trunk with rice straw or other materials, then tie it tightly with rope to prevent cold wind and rain from damaging the trunk. In addition, whitewashing the trunk is also a commonly used cold-protection method. Using a lower-concentration lime solution to whitewash the trunk can increase the trunk's cold-protection and freeze-resistance ability so it can overwinter safely.

3. Protect the growing nodes

Before the winter cold wave arrives, wrap the top of the plant or the crown with rice straw or plastic film. This can protect the plant's growing nodes from freezing to death, and in early spring of the following year, as the temperature rises, new buds can sprout as much as possible.

4. Smoking in the orchard

Many fruit growers often use the smoking method to raise the orchard temperature and reduce the losses caused by freeze damage. However, when smoking, pay attention to doing it on a clear and windless night. Rice straw, rice husks, sawdust, turf mud, etc. can be used to make a fire and produce smoke in the orchard. At this time, it can prevent cold air from sinking or frost particles from forming, effectively protecting the plant's leaves.

5. Sprinkling water

In the morning after frost particles form, spray clean water on the plants to wash off the frost particles. This can reduce the damage caused by frost particles to the plants, and can also maintain a certain amount of moisture and increase the ground temperature, so the plants can overwinter safely.
