The latest anti-freezing methods of citrus in winter
Citrus is widely planted in China, and it is planted in both the north and the south. It is low in winter, and citrus in many areas is vulnerable to freezing damage, resulting in economic losses. How to survive the winter safely in winter and reduce frost damage is also a concern of fruit growers. The following pro-agricultural network brings citrus anti-freezing technology in winter. Let's take a look.
1. Irrigation and anti-freezing
Irrigation can play an anti-freezing effect in winter, irrigation can increase soil specific heat capacity and air humidity, can effectively restrain ground radiation and delay the decrease of ground temperature. Generally, planting irrigation can increase the low temperature by 1-2 degrees in winter. But irrigation should also pay attention to the time method, according to the size of the plant and the dry moisture of the soil, pay attention to irrigation at dusk in the afternoon during frost, and drain the water in the early morning.
2. Smoking and anti-freezing
When the winter temperature is low, when the citrus suffers frost, you can smoke in the orchard to prevent frost, use local materials in the orchard, light the smoke in the open and ventilated place, and make the smoke cover the whole orchard, which can increase the temperature in the orchard by 2-3 degrees. But it should be noted that do not produce large-scale open fire, and there should be a certain distance from the plant, but also at the upper entrance.
3. Covering film to prevent frost
Covering a layer of film on the plant is also a good anti-freezing method, covering the film can reduce a certain amount of cold wind, reduce the evaporation consumption of plant water, and has a good heat preservation effect on the soil layer. But it also has its shortcomings, the film is close to the leaves, the permeability is poor, and the leaves are easy to burn in sunny days, so many people generally use this technology to support it, which is equivalent to building a small greenhouse.
4. Spraying antifreeze
In many areas, fruit growers choose to spray antifreeze, a foliar fertilizer containing plant hormones or trace elements. Their function is to maintain the stability of the biofilm, reduce the damage to the membrane caused by low temperature, reduce the freezing point of the cell wall, and make the plant achieve a good anti-freezing effect.
The above are the anti-freezing methods of citrus in winter brought by the pro-agricultural network, in addition to the above methods, there are other anti-freezing methods, such as adding fertilizer, making use of the characteristics of decomposition and heat dissipation of fertilizer, increasing the temperature of soil and roots to prevent frost, and plastic film mulching and so on.
