Detailed measures for cold protection and overwintering of papaya to ensure the plants survive the winter safely

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

1. Pay attention to the 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, adding 1-2 kg in appropriate amounts. At 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 excavated soil, 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. Binding 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 and frost resistance, helping it overwinter safely.

3. Protect the growth nodes

Before the winter cold wave arrives, wrap the top or canopy of the plant with rice straw or plastic film. This can protect the plant's growth 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, attention should be paid to choosing a clear and windless night. Rice straw, rice husks, sawdust, turf mud, etc. can be used to make fires and produce smoke in the orchard. This 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 have formed, spray clean water on the plants to wash off the frost particles. This can reduce the damage of frost particles to the plants, and can also maintain a certain amount of moisture, increase the ground temperature, and help the plants overwinter safely.
