关于这种疾病
Soft rot is a condition in which the stem or caudex of a plant becomes water-soaked and decays due to bacterial infection (such as Erwinia spp.). It can progress rapidly from wounds or high-humidity conditions, making early response essential.
主要症状
- Part of the stem or caudex becomes water-soaked and soft
- The affected area turns brown to black and emits an unpleasant odor
- Symptoms spread rapidly to surrounding tissue within a few days
- Tissue around the affected area collapses and becomes sunken as it breaks down
主要原因
- Bacterial entry through wounds from pruning, pests, or physical injury
- Overwatering during hot, humid periods (rainy season and summer)
- Persistent humid, poorly ventilated growing conditions
- Long-term cultivation in poorly draining soil keeping the root zone constantly wet
预防（栽培环境与日常管理）
Allow cut surfaces from pruning or physical wounds to dry out promptly and avoid exposing them to humidity. During hot, humid periods, improve ventilation and reduce watering frequency. Regularly inspect the plant, paying close attention to the stem and caudex for any early signs of softening or discoloration.
