Fruit tree frostbite prevention and treatment method (2)
1. Adopt "warm belt" planting.
Select the "warm belt" area when building the garden. Hills and mountains avoid planting in low-lying areas to prevent frost from hitting the ground. Fruit trees planted in warm zones are generally lighter in frost.
2. Choose cold-resistant tree species or varieties.
Different tree species or varieties have different cold resistance ability, and should be selected when building the garden.
3. Increase fertilizer application.
Before and after fruit picking, the annular groove was excavated at the outer edge of the tree to apply the farmyard manure, and the appropriate amount of nitrogen, phosphorus and potassium fertilizer was applied. After fertilization, the lighter manure was poured and the soil was covered.
In the late autumn or early winter season, deciduous fruit trees, especially 1-2 year old deciduous fruit trees, can be properly trimmed or artificially decidated to reduce tree consumption, increase accumulation, and improve cold and frost resistance.
5. High replacement.
The high cold resistance of the local saplings, or the high-name, excellent, new, special and rare varieties on the cold-resistant rootstock can improve the cold resistance of the plants.
6. Painted white trunk.
At the end of autumn and winter, the trunk is painted white in combination with the Qingyuan. Firstly, 5 kg of quicklime and 1 kg of salt were melted with 20 kg of hot water respectively, and then the two liquids were mixed and stirred, and 0.5 kg of the raw material of the stone sulfur mixture and 0.1 kg of the vegetable oil were uniformly stirred to prepare a whitening agent. One is the overwintering bacteria and eggs that can kill the trunk; the second is to enhance the ability of the sun to reflect, reduce the large changes in the temperature difference between day and night, and avoid the sunburn. When drying, fill the trunk all the way until the branch of the main branch.
7. Clear snow.
When it is snowing, it is best to shake the tree in time to shake off the snow on the trunk to avoid crushing the branches and reducing frost damage.
8. Winter irrigation antifreeze.
After one and a half months of fruit picking, when the soil is “freezing and freezing”, the trenches are dug between the rows of fruit trees, and then the water is drenched along the furrows. The amount of water is better to seep before the night. It can not only achieve winter water use, prevent spring drought, promote the growth and development of fruit trees, but also store water in the water to keep the ground temperature relatively stable during the cold wave, thus reducing the freezing damage. After winter irrigation, it is best to cover the grass, but also shallow on the surface to prevent evaporation of water.
In the winter, fruit trees, especially young fruit trees, are often subjected to low-temperature freezing damage, light flower buds frostbite, heavy branches or whole plants frozen to death. The freezing damage of fruit trees should be based on prevention and supplemented by treatment. We provide high quality against frost candles for orchard managers.
