Measures for preventing cold and overwintering of papaya

Papaya is a tropical fruit tree that likes high temperature, but is afraid of frost. It often suffers frost damage in the south and causes plant death in severe cases. It is very important to take anti-cold and anti-freezing during cultivation. Let's take a look at the detailed introduction with the editor below.

1. Attach importance to overwintering fertilizer

Before the advent of winter, 15-20 kg of organic fertilizer mixed with rotten human and animal manure and plant ash was applied to each plant, and an appropriate amount was added 1-2 kg. At 80-100 cm from the trunk, dig a circular ditch 20-30 cm deep and 30-40 cm wide, mix the fertilizer with the dug soil, and backfill the ditch, or a layer of fertilizer and a layer of soil. After fertilization, the tree tray should be covered with straw to increase the soil temperature and make the roots survive the winter safely.

2. Binding and whitening

Before winter comes, wrap the trunk with straw or other objects and tie it tightly with a rope to prevent the cold wind Rain Water from harming the trunk. In addition, tree trunk whitening is also a common means of cold protection, using lower concentration of lime water to whiten the tree trunk, can increase the tree trunk cold resistance, so that it is safe to survive the winter.

3. Protect the growth node

Before the cold wave in winter, use straw or plastic film to cover the top or crown of the plant, which can protect the plant's growth nodes from freezing and death, and sprout as much as possible as the temperature picks up in early spring.

4. Smoke in the garden

Many fruit growers often reduce the loss caused by freezing injury through the method of smoking and the temperature of the orchard, but smoking should pay attention to the use of rice straw, grain husk, sawdust and turf mud to make smoke in the garden on a clear and windless night. At this time, it can prevent the sinking of cold air or the formation of frost particles, and effectively protect the leaves of the plant.

5. Sprinkle water

In the morning after the formation of frost particles, spray clear water on the plants and wash them off, which can reduce the damage of frost particles to the plants, maintain a certain amount of water, increase the ground temperature, and make the plants survive the winter safely.
