Since mid-January, the temperature in the Yangtze River valley has plummeted. The minimum temperature is below minus 4 degrees Celsius, and the frozen weather in rain and snow is maintained, causing severe frost damage to the citrus, especially when the drought is dry and drizzle, resulting in the effect of dry freezing on the tree. Even bigger, if we do not take timely measures to restore the post-frozen tree vigor, it will cause a significant reduction in citrus production this year. The main measures for post-freezing management include the following: Water spray to wash shade When it is sunny and clear after being frozen, spraying water, spraying or sprinkling the water to wash the tree can prevent the temperature from rising rapidly, reduce the thawing speed of the tree, and reduce the evaporation of the water in the leaves, so as to reduce the freezing damage. After the weather is fine, the canopy can be covered with rice straw or other covering materials to minimize direct sunlight and prevent the temperature from rising rapidly after turning fine. Let it thaw slowly. Soil insulation Immediately after thawing, the soil is thawed under a frozen orange orchard, with a depth of 10 to 15 cm. By cultivating loose soil, the soil is loosened and ventilated, the temperature rises, root activity is promoted, and vitality is restored to achieve the objective of raising the roots and protecting the leaves; The dried orange orchard needs more water to supplement the roots and trees. It can be sunny and sunny in sunny days, and it can reduce the freezing degree of citrus. Fertilization After freezing, the function of the tree is significantly weakened. If the damage to the canopy after freezing is serious, it must be fertilized as soon as possible to promote the development of more shoots and strong new shoots to promote the restoration of tree vigor; the top-dressing fertilizer should be quick-acting nitrogen fertilizer and water-belt fertilizer. , Diligent application of thin application; combined with cultivator loose soil, per plant manure excrement 10-25 kg, or urea 0.5-1.5 kg; also according to the extent of frost damage, every 10 to 15 days foliar spray Urea, zinc fertilizer, boron fertilizer mixture 2 ~ 3 times, promote its recovery as soon as possible. Properly trimmed Post-freezing pruning can be combined with spring pruning, generally starting in mid-March and adopting different pruning methods according to the severity of the degree of frost damage; freezing and less light should be cut or not cut, try to protect the leaves for stable production in the year; moderate freezing damage The tree body must be cut off the dead branches to promote their germination, quickly restore the tree vigor, and strive to achieve the results of the year; severe freezing damage to the tree body, to saw the frozen main branch or stem, the incision with paraffin or other fungicides (Bordeaux solution Or carbendazim) seal disinfection, so that the incision site germination of new shoots, and timely plastic surgery, expand the crown, sorting the tree of orange trees, but cut not too much, try to retain the green branches, in order to facilitate the restoration of tree vigor. Pest control Damaged branches and leaves of the orange orchard after freezing are susceptible to pests and diseases; Resinous disease (also known as fluidic disease) is most likely to occur after freezing, and emphasis must be placed on prevention and treatment; water tar (5 for asphalt, 1 for diesel and 4 for water) Gadopentine 0.2 parts, smear lesions, have a good control effect, pay attention to scraping before the application of plastic materials on the lesions; in addition, we must pay special attention to control anthrax and spider mites and other harmful leaves Pests, to promote the growth of leaves, shoots; on the frozen citrus trees, in the summer, branches, dry white, prevent sunburn caused by trees, dry skin, and prevent resin disease; coated with lime water to join The amount of yellow mud and cow dung is better.
