What to disinfect the rotten roots of the rich tree
Fortune trees are a popular choice for home green plants, and more than 65% of their maintenance problems stem from abnormal roots. When the leaves are found to be yellow and the basin soil smells rancid, large areas of decay have often formed in the roots. This paper systematically analyzes the entire process of disinfection treatment and regeneration maintenance based on different degrees of decay. The full-process dual disinfection treatment plan for root rot disinfection requires stepped disinfection for deep rot: first soak in 0.1% potassium permanganate solution for 30 minutes to sterilize, and then replace it with 1000 times thiophanate methyl solution for secondary treatment. Focus on treatment at the junction of tubers, where the mold density is usually 3-5 times higher than that of ordinary roots. After soaking, be sure to use a medical cotton swab to dip Sukeling and apply it to the incision, which can shorten the healing period by 40%. The four-step precision pruning technology for rotting plant regeneration uses alcohol-burned scissors to obliquely cut the rotting root system 2 cm along the healthy tissue. When brown stripes appear on the section of the tuber, continue to be removed until the section appears uniform and milky white. Experimental data shows that retaining more than 5 aerial roots can increase the survival rate to 78%. Systematic sterilization treatment was carried out to prepare 800 times of carbendazim solution for spraying the whole strain, focusing on trimming the wound surface. Simultaneously use 0.5% copper sulfate solution to irrigate the soil of the original basin to completely eliminate hidden bacteria. At this stage, it is necessary to maintain the environmental humidity of ≤60% to avoid forming a hotbed of secondary infection. The principle of substrate reconstruction adopts a 3:2:1 perlite/river sand/leaf soil formula, and the porosity needs to reach more than 35%. Soaking the substrate with rooting powder solution before putting into pot can increase the germination speed of new roots by 2.3 times. After planting, gently press the basin soil to a natural settlement state to avoid excessive compaction and affecting ventilation. During the restoration period of light and fertilizer control,"three control management" is implemented: water control (watering thoroughly once every 7 days), temperature control (20-25℃), and light control (20000lux scattered light). After the new buds germinate, add liquid fertilizer containing calcium trace elements every month to enhance the anti-corrosion ability of the cell wall.
Through phased disinfection and regeneration management, 89% of moderately rotten plants can return to growth within 90 days. The key is to grasp the golden rescue period of two weeks before the onset of the disease, regularly check the humidity of the basin soil and the status of the root system, and use pH test paper to monitor the pH value of the substrate (ideal value of 6.2-6.8) to prevent the recurrence of rotten roots from the root cause.
