A tree root moisture absorption method selects a glass bottle with a volume of 100 ml into a trace element nutrient solution. Dig a pit 1 meter away from the root of the fruit tree. When the roots are exposed, pick a rough 0.5–1 cm root to cut it horizontally, insert the root of the connecting trunk into the bottle, and seal the gap between the bottle mouth and the root of the tree. , The root of the tree is buried underground together with the bottle, allowing it to slowly absorb. Second, the tree trunk injection method first take two bottles with a volume of 50 ml containing trace element solution. Drill holes on the sides of the trunk 20 cm above the ground, deep to form a layer, and hung a bottle near each hole. Then twist cotton into a cotton core, insert one end into the trunk hole, and put the other end into the trunk hole. In the bottle, let it absorb slowly. 3. After the fruit trees are painted and sprouted, if a diseased branch is found, wipe the brush with a brush or a row of pens with a good trace element solution to wipe the branches for 1 to 2 years. Wipe again every 10 to 15 days. IV. After the spray method has formulated the trace element solution, the canopy is evenly sprayed with a high-pressure gun. The leaves are mainly used to allow the fruit trees to hang evenly from top to bottom. If the patient is seriously ill, spray it again 10 days later.
