1. 1. Reconstructing and transplanting Sophora japonica: According to the uniform trunk height of 2.2-2.4m, select skeleton branches within the top of 20-40cm, leaving 3-4 main branches for "three directions", that is, fixing branches, positioning and orientation. Each main branch is sheared 30 ~ 40cm away from the main branch, and the base of the redundant branches is all thinned, and the balanced root-shoot ratio is divided to lay the first level for improving the survival rate. 2. Disinfection treatment: the repaired Sophora japonica is smeared or wrapped, the purchased nourishing oil is mixed with a small amount of gasoline, all of which are smeared on a saw, and the saw is basically sealed with a layer. Or use plastic bags to cut off the top of branches by 3 to 5 centimeters. Comparatively speaking, dressing is more troublesome and the progress is a bit slow. At the same time, pay attention to coating a layer on the skin. Only in this way can evaporation be significantly reduced and the survival rate be improved. 3. While doing the above work well: make unified planning according to the standard, drill holes at the distance of 6 meters from the road surface 1.2 ~ 1.4, with a width of 80 cm and a depth of 80 cm, and separate the topsoil from the raw soil, and pick up stones and construction waste for planting. 4. Hoist the restored trees: leave the roots as long as possible, trim the cut roots with fruit branches with a diameter less than 2 cm, clean them with a saw with a diameter greater than 2 cm, and then spray all the roots with 50 times carbendazim or thiophanate to promote early healing and quick rooting. 5. Transplanting: backfill the dug tree hole with 20 cm topsoil, and hang the treated tree to the center of the tree hole to form rows and columns. Backfill the raw soil into the tree hole. When the hole soil is 20 cm from the ground, the two men shake the tree a few times to make the root system closely combined with the soil, and then tamp it, taking care not to hurt the root system. Fill it and compact it, and then make it into a square hole with a height of 20 cm, ready for watering. Water will be poured twice, and the hole will be sealed in time after drainage. /kloc-once every 0/0, once every 10 to 15, depending on the rain. 6. After the trees germinate, spray water once every 1 to 2 days to accelerate the growth of new buds. And pay attention to the fact that new buds are vulnerable to aphids, and observe and spray them in time when the weather is dry. In a word, to do this work well, we need experienced professionals to give technical guidance, so as to achieve the expected results.
