In recent years, many southern orchards often suffer from continuous frost or low-temperature ice and snow conditions, which cause varying degrees of frost damage to evergreen fruit trees. Therefore, while enhancing the capacity of antifreeze and cold resistance in an orchard, it is particularly important how to do a good job of remedial care after fruit trees to reduce damage and restore tree vigor. Combining the production practices of the past few years, the author puts forward the following points of fruit tree restoration measures for reference by farmers. 1. It is advisable to spray the foliar fertilizer in time when the trees are slightly under freezing. Leaves yellowing and curling due to cold dew, morning frost, or late spring cold. The last-stage shoot-blow or declining tree vigor can be immediately selected by Green Fenwei, Green Wind 95, pp2003, Plant Antifreeze, Superphosphate Leachate, or Phthallic Acid II. Hydrogen potassium plus urea for leaf fertilizer spraying 2-3 times. Note that the application concentration should be slightly lower than the usual application concentration. 2. Trees that are permanently wilted by frozen foliage should first be rooted. Suffering from abnormally cold weather or continuous frost, the loss of water in the leaves of fruit trees is serious. When permanent wilting occurs, irrigation in orchards should be strengthened, cultivating tillage, and thick layers of straw be covered in the tree trays. At the same time, the withered leaves, lightly water-lost end dead branches were removed, and the water supply balance between the upper and lower ground areas was removed and the roots were not affected. 3, pruning after freezing should be carried out in the spring bud. Fruit trees should not be trimmed immediately after being frozen in winter so as not to increase the degree of frost damage. If branches and branches are broken by ice and snow, they should be bundled in time, and pillars or hanging sticks should be set up to keep and rescue wounded branches. Generally frozen leaves or dry branches should be postponed until the spring buds and then pruned, insisting on the principle of "heavy wounds and light injuries." Select fine weather when pruning, generally short cut should be cut to 2 cm below the healthy part. When truncated or retracted to the main branch and sub-main branch, the appropriate and proper buds shall be selected according to the condition of the crown base branches. The buds shall be sawn at 2 cm and the main branch and the sub main branch shall be re-cultured. If the trunk and the main branch of the cortex are cracked and the entire canopy freezes to death, the trunk can be sawn off at the proper position on the grafting interface, and the branches can be re-emerged to form the trunk. Saw mouth should be flat, with 75% alcohol disinfection, and then coated with Bordeaux or yellow mud cow slurry and other protective agents. After the frozen tree is pruned, the sprouts are germinating and disorderly, and the buds should be timely picked up and the crown restored as soon as possible. 4, prevent pests and diseases after freezing. After the fruit trees are debilitated after being frozen, organic fertilizers should be added to prevent floods and prevent diseases and pests. In particular, after resin, the resinous disease most likely to occur after freezing is that the diseased skin can be scraped off in mid-May and mid-September. After being washed with 75% alcohol, it is then smeared with 58% metalaxyl manganese zinc 100 times, or 80% satade, 20 times or 64% antiviral 20 times, or cow dung, yellow mud, dt agent (1:2:0.1) plus appropriate amount of hair mix, the effect is ideal. In addition, we must promptly control locusts, mites and moths and butterfly pests, and protect the smooth growth of new shoots to facilitate the restoration of tree crowns. Beeswax is obtained from the honeycombs of bees after the Honey has been removed by draining or centrifuging. The combs are melted with hot water, steam or solar heat; the melted product is filtered and cast into cakes of yellow beeswax. With detoxification, wound healing, tissue regeneration, pain relieving effect. Commonly used in the ulcer not healing, ecthyma erosion, ulceration of trauma, burn and scald.
