Anti-freeze measures for frost-falling trees
Before the soil is frozen, pour the antifreeze water once and pour it through; after freezing, it is not suitable to refill the water to avoid freezing damage. The tree body fully absorbs and stores a large amount of water, which can slow the transpiration of water in the winter tree. Increased soil moisture, improved orchard microclimate, reduced or avoided sapling, pumping or death. For mature trees, pouring anti-freezing water is good for germination, leaf and flower bud differentiation, flowering, and fruiting. Measure 2: burying the soil and preventing cold Before the soil is frozen, the young trees with poor cold resistance should be trimmed, dropped, trenched, and buried. The depth, width and length of the ditch are determined by the size of the tree. Generally, the depth and width are 30-50 cm, and the thickness of the surface layer is 15-20 cm. The young seedlings are large or adult fruit trees, and the branches are hard and can not be pressed down. That is, the soil is piled up with the base of the tidal soil, and the soil pile is 30-40 cm above the ground, and the root neck is cultivated. Note that when the soil is buried, the surface of the soil should be smooth and tight, and the wind will not leak. Measure three: trunk binding Before entering the winter, the trunk or main branch is wrapped with straw rope, which can prevent the cold wind from invading and reduce the loss of trunk water. Before winding, it is best to immerse the entangled material in lime water for 1-2 days to prevent the pests from invading the fruit trees. Measure 4: Smoke smoke warming Smoke should be carried out in the cold winter night. The fuel is ignited at around 12 o'clock at night with sawdust and firewood. It is necessary to control the fire. It is better to use dark fire and smoke. It is not possible to use an open flame to prevent fire. Generally no less than 3-4 fire points per acre. The fumigation method can increase the temperature of the orchard by 3 °C - 4 °C. Measure 5: Trunk painted white Beginning in the middle and late October, combined with the Qingyuan, a layer of white protective agent is generally applied to the trunk and main branches of the fruit trees. Enhance the ability to reflect sunlight, make the temperature difference between day and night smaller, prevent or reduce the sudden freezing of the trunk and main branches, causing "frozen wounds"; killing the pathogens and eggs on the trunks and branches over the winter, and preventing the wintering pests and diseases.
