Does your fruit tree prepare to against spring frost?
Time flies, in a blink of an eye, we have enjoyed the summer fruits, the autumn yellow leaves, the winter snow, and will soon welcome the spring flowers. Do you remember the winter? Winter is a cold season, we will wear thick cotton coats, and how should trees exposed in nature be cold? How deadly damage will winter bring to them?
Most of the fruit trees in the north are deciduous in winter, and they are protected from the cold with naked trunks. Although the leaves of the southern fruit trees still exist, they still can not withstand the low temperature damage, so the management of fruit trees to prevent freezing damage should be placed at the top of the list. What is the situation of fruit tree freezing damage? What impact will it have?
According to a long-term investigation by the Henan Jiafa Crop Research Institute, the freezing damage of fruit trees and ornamental trees means that when the temperature is lowered to a certain extent, the freezing of water in the plant body fluid causes the water to freeze between the cells, causing the water potential to drop, resulting in the loss of water inside the cells. A process in which the cytoplasm concentration becomes high and the cell volume shrinks, leading to the gradual death of cells and tissues.
The main damages of trees are
1. The leaf is the main part of the plant photosynthesis. After freezing, the leaves are stiff, hard and the leaves become smaller. The leaves are large and thin and are susceptible to freezing. The leaves are small and the waxy layer is not easily frozen. The young leaves with sufficient leaf moisture are easily frozen. The leaves around the trees are more susceptible to freezing than the inner leaves.
2. Flower buds are important organs for tree differentiation and the weakest part of frost resistance. It is generally damaged by freezing in early spring, and the top flower buds are most seriously damaged by freezing.
3. The damage of the branches is generally caused by local damage. The mature branches are in the dormant period to form the layer which is most resistant to cold and skin, while the xylem and pith are the least resistant to cold. Generally, the late-ripening branches are poor in cold resistance, and the branches that are damaged by freezing are generally not easy to find. It is found that the phloem becomes brown with a knife and the phloem becomes brown. The new shoots at the top are most likely to cause freezing damage.
4. The trunk will generally appear longitudinal cracks, also known as freezing cracks, which means that the bark is lumpyly separated from the xylem or rolled outward along the crack. The reason for the freezing crack is that the temperature suddenly drops to zero, the bark Rapid cooling and shrinkage, resulting in uneven internal and external tension of the main tissue, and thus cracked from the outside to the inside, or the bark from the xylem. The freezing crack of the trunk often occurs at night, and as the temperature warms, the frozen crack can gradually heal. The parts that form frost damage are most prone to decay in the coming year.
Impact of freezing damage
The above describes the frozen part of the tree, we can imagine the harm of the coming year? Any part of the tree is the key to harvest, such as: leaf freezing damage, affecting photosynthesis, and affecting the transportation of nutrients and water. Flower buds are directly related to the number of flowers, and where are the fruits that come from? The branches are frozen, and the nutrients can be transported to the fruit without deformed fruit and small fruit. As the saying goes: the branches and leaves are flourishing, only the branches, leaves and flowers are protected, and the yield is only in the coming year. The main damage is not much and will heal as the temperature rises, but if you don't pay attention to it, causing decay in the coming year is a major threat to the production and the life of the tree!
Although the impact of freezing damage is relatively large, but the technology is constantly developing and progressing, you can place anti-freeze candles between the fruit trees. The antifreeze candles we provide can burn for up to 8 hours to improve the cold resistance of the fruit trees. This is a first aid method to prevent freezing damage. Finally, I hope that when you are looking for a reliable orchards antifreeze candle wholesaler, you can think of Tabo, a professional antifreeze candle manufacturer.
