Indications: sore throat, common cold, fever, abdominal pain, stomachache, acute and chronic hepatitis, diarrhea, enteritis, heatstroke, abdominal pain and rheumatoid arthritis. External treatment of scald, traumatic injury, furuncle and neurodermatitis. When transplanting big trees, root treatment generally includes three aspects: root pruning, determination of root soil ball size and root topdressing.
First, root pruning
Transplanting with soil balls is generally advocated. In order to ensure the survival of trees and promote the growth of fibrous roots of trees, the roots are generally treated in advance 1~2 years before transplanting (depending on the actual situation), and the roots can be cut off in advance and the lateral roots around the trees can be cut off in different years. Root cutting time should be carried out in spring and autumn, and the range of root cutting is five times that of DBH, so as to promote the germination of new roots and benefit the survival rate of big tree transplantation.
Second, the soil ball size
The size of the ball dug from a big tree is generally 4~7 times that of the DBH of the tree. If possible, try to increase the soil ball to ensure that it is complete and not loose. In the process of excavation, in order to prevent loose balls, the thick roots should be sawed off or cut off with sharp branches, and it is forbidden to dig hard with a hard shovel.
Thirdly, the root surface is trimmed
After the trees are dug, the root balls should be packed in time. Straw curtain and straw rope are good packaging materials, which are economical and rich in resources. Generally, if the diameter of trees is less than 15cm, and the excavated soil balls are round dense soil, they can be packed with cloth bags, woven bags, straw ropes, etc. For trees with large DBH, it is best to dig a square soil platform and pack it in existing wooden boxes.
When transplanting, it is best to use vitality or rooting agent to ensure survival. At the initial stage of transplanting, the root system has low fertilizer absorption capacity, so it is appropriate to apply fertilizer outside the root, generally every 15 days 1 time. The fertilizer can be quick-acting fertilizer, such as urea, ammonium sulfate, potassium dihydrogen phosphate, etc. , prepared into a liquid fertilizer with a concentration of 0.5%~ 1.0%. They should be sprayed on the leaves in the morning and evening or on cloudy days, and sprayed again 1 time in rainy days. After the roots germinate, soil fertilization can be carried out, which needs to be applied thinly, and care should be taken to prevent the roots from being damaged.
