Diagnostic Guidelines for Root Rot Crisis 1.1 Identification and Observation of Typical Symptoms The plants showed the characteristics of "three yellows and one softness": yellowing of new leaves, scorched yellow edges of old leaves, yellowing of intervein patches, and softening of the base of branches. When roots are severely rotten, brown mucus can be seen seeping out, and tapping the tree trunk makes a hollow sound. 1.2 Pathological traceability analysis 80% of rot is caused by excessive watering, and 20% is caused by soil hardening or low-temperature freezing damage. It can be judged by checking the humidity of the basin soil: take deep soil and knead it. If it stays in a lump and gives off a musty smell, there is a risk of water accumulation. Second and Four-Step First Aid Operation Manual 2.1 Surgical debridement uses alcohol-disinfected gardening scissors to remove decaying tissue at a 45° angle until healthy white-green woody parts are exposed. Pay attention to retaining 2- 3 cm of healthy cortex to form a callus growth area. 2.2 Deep sterilization treatment is prepared with hydrogen peroxide (3%) or carbendazim (800 times solution) to soak for 30 minutes, focusing on treating the incision site. Avoid direct sunlight when drying and place in a ventilated and cool place for 72 hours to form a protective film. 3. Cultivation plan for sawing and rebirth 3.1 Stem cutting and root promotion technology, keep the main trunk 15-20cm, apply rooting powder to the incision, and use river sand + perlite (1:1) substrate for cuttage. Keep the temperature at 25-28 ° C and use a transparent cover to create an 80% humidity environment. New roots can germinate for about 20 days. 3.2 At the beginning of hydroponics and soil culture techniques, root systems can be induced by hydroponics, and then 3cm white new roots can be transformed into soil culture. Keep the substrate moist during the transition period and supplement HB-101 plant vitality every week to increase the survival rate to more than 90%.
