Mud control
Take fresh soil and mix well with water. The degree of wetting can be adhered to the bark by hand, and 3-5 cm on the fruit tree disease, then tightly wrapped with plastic film to prevent evaporation and soil loss. After 1 year, the plastic film and mud were removed. In this way, the aerobic bacteria will suffocate and die due to chronic hypoxia. The cure rate of this method is above 90%.
Salt water impregnation
Use 1 kg of salt and 40 kg of water to make a 1:40 light salt water, boil and let cool. Scrape the fruit tree rot and use a brush or brush to apply the salt water to the diseased sputum and damp it into the bark to disinfect and disinfect. Apply again 2 weeks later. The cure rate of this method is above 80%.

The edible base and water were made into an alkali solution in a ratio of 1:5. Scrape the diseased sputum, and apply the alkaline water to the wound of the disease with a small brush. The surrounding area is about 5 cm beyond the disease, so that the alkali solution can be fully impregnated into the bark. Then, use a plastic film to tightly tie it. It is carried out once more after 10 days, and the plastic film is usually released after half a year. The cure rate of this method is above 85%.
Garlic sterilization
Garlic is chopped into garlic, and 10% saline is added in a ratio of 1:1 to prepare garlic. When using, first scrape the disease, use a small brush or a brush to spread the garlic on the wound of the disease, and the surrounding area should be 3 to 5 cm beyond the disease.

Chili wine sterilization
50 grams of pointed red pepper (better fresh pepper), chopped into 500 grams of white wine, sealed for half a month after use.

Traditional Chinese medicine preparation
After scraping the lesion, apply it with the septic liquid. Apply a small brush or a brush to the wound of the disease. The surrounding area should be 3 to 5 cm beyond the disease, and the interval should be repeated once every 7 days. Sterilization, the most important role is to heal the wound. The tree has a healing width of more than 1 cm and does not recur.
Diamond Wire Saw (referred to as wire saw) is formed by sintering and electroplating. The artificial diamond particles are consolidated on the metal steel body to make diamond beads, and then the beads are strung on the Steel Wire Rope. Through special molds and equipment, glue injection, injection molding, and fixation are performed to manufacture strip-shaped flexible diamond cutting tools. The emergence of Diamond Wire saw mining technology in stone mines is undoubtedly a revolution in stone mining. The technology for stone mining has wide adaptability, strong function, high efficiency, deep mining depth, and can be cut in various directions such as vertical, horizontal, and inclined planes, high yield, low comprehensive cost, safety and environmental protection, and no noise in wire saw mining. No dust and other advantages.
