What should I do if my son is rotten?
As an expert in the meat of Crassulaceae, Zi Chinianhua is deeply loved by meat friends for its unique rosette shape. However, many novices often encounter the crisis of rotten roots during the maintenance process. This article will start from the three major root causes of the disease and systematically analyze the prevention and treatment plans for rotten roots in the past. The three major culprits of rotten roots in Zi Zhi 'an analyzed excessive intervention: the invisible killer of root damage. 70% of root rot cases stem from improper operation: frequent pot removal inspections, violent plant separation and other behaviors lead to root damage. Newborn root hair is as fragile as capillaries, and every time it is forcibly removed, it will cause irreversible damage. It is recommended to use a transparent seedling pot to observe the root system, and only need to check the root system status of the vent holes in the bottom of the basin every month. Misoperation during hibernation period: Changing pots in winter is contraindicated. During hibernation in winter, metabolism drops to freezing point. Changing pots at this time is equivalent to performing thoracotomy on plants. The data shows that the mortality rate of plants after changing pots during the dormant period is as high as 82%. The correct approach should be to change pots during the spring and autumn growing season (15-25℃), and 1/3 of the original soil should be retained to protect the root system. Imbalanced medium ratio: The ideal cultivation substrate for the root death trap should contain 60% particulate soil (red jade soil + volcanic rock)+30% nutrient soil +10% vermiculite. When the soil is too viscous, for every 10% decrease in root oxygen supply, the risk of root rot increases threefold. Moisture can be detected by inserting bamboo sticks, and water needs to be controlled when the bamboo sticks are carried out of the soil. Five-step rescue and accurate diagnosis of rotten roots: grading the degree of rotten roots, what should I do if I have rotten roots?
Level 1 rotten roots (black root tips): Cut off the diseased roots, soak in carbendazim (1:1000) for 30 minutes, dry the roots for 3 days, and replant them in humid soil. Second-level rotten roots (main root lesions): Keep healthy stems for cuttage, and place the mother plant in a ventilated place to induce new roots. Level three rotten roots (whole plant rot): Remove complete leaves for leaf insertion and propagation. Scientific cuttage: Select a walking stem with air roots in the walking stem regeneration technique, apply rooting powder to the incision and lay it on the surface of perlite. Keep the environmental humidity of 70% and the temperature of 18-22℃, and new roots can germinate in 7-10 days. Key points: Water was completely cut off in the first 3 days, and spray water supply method was used in the subsequent period. Golden rule of maintenance: Three control tips to control water: water is permeable every time in spring and autumn, and water is supplied along the basin every time in summer 15 days. Temperature control: Keep the temperature above 5℃ in winter, and control the temperature below 30℃ in summer. Fertilizer control: Add 2000 times diluted liquid fertilizer once a month during the growth period.
Through scientific diagnosis and precise rescue, 85% of the rotten people can be reborn while they are old. The key is to grasp the nine-character policy of "early detection, rapid processing, and intensive maintenance", and cooperate with the correct medium ratio and environmental control to ensure that your child's years of survival will be restored to vitality.
