I believe everyone knows that if the fruit trees we planted do not have antifreeze measures in the winter season, they will be easily affected by the freezing damage. So everyone knows which parts of the fruit trees are susceptible to freezing damage during the winter? Only those who know these We will be able to carry out anti-freezing measures more specifically. Then let Xiaobian explain it.
First, the branches of the fruit trees
1. The delicate branches of fruit trees
Because the period when the fruit tree stops growing is relatively late, if it is not yet mature, it is not able to withstand the low temperature of winter.
2. Branches of fruit trees
Even the branches that grow normally in fruit trees are susceptible to freezing damage when the temperature is very low in winter. Some branches may be very normal in appearance, but may have been frostbitten in the xylem of the branches. Even if the frozen branches do not die immediately, they will hinder the transmission of nutrients and affect the overall growth of the fruit trees.
Second, the root and neck of the fruit tree
The root and neck of the fruit tree is relatively late in the dormancy period. The soil temperature is generally low near the ground, so the root neck of the fruit tree is also particularly vulnerable to winter frost damage, and even in severe cases, the death of the whole fruit tree can be caused. .
Third, the flower buds of the fruit trees
The flower buds of fruit trees are mainly affected by the high and low temperature of the air temperature, which makes the resistance of the flower buds of the fruit trees weaken, so that the cold weather in winter invades and thus suffers from freezing damage.
Fourth, the root system of the fruit tree
The root system of the fruit tree is present in the soil layer. If the root system is floating up in the soil layer because of the large number, or the soil planted by the fruit tree is too loose, the winter cold will take the opportunity to invade, causing the root of the fruit tree. Frost damage. The main manifestation of frost damage in the roots of fruit trees is that the spring buds of the fruit trees sprout too late or not.
The above is the introduction of the fruit trees that are susceptible to frost damage in the winter. Knowing this knowledge, all the growers and friends can take appropriate measures to prevent freezing in the anti-freezing of fruit trees. When the fruit trees are frozen, the problem can be judged more accurately. .
