Physical diseases can only prevent it from happening. It is possible to improve cultivation conditions, strengthen ventilation and light transmission, and avoid excessive humidity. In particular, some fish tank-type cultivation boxes should be regularly taken out of the plant to be loosened, and the sunlight should be allowed to stand in the bottom of the box for a while. Other measures include not using excessive nitrogenous fertilizers, often turning pots and changing soil, not spraying plants with low-temperature water, and avoiding sharp drop in temperature at the cultivation site.
Physiological disease prevention
Physiological diseases refer to the gradual growth of yellow-brown rust or cork patches caused by poor plant growth, poor plant growth, detachment of young stems, dark gray leaves, irregular stem segments or spheres due to poor environmental conditions and improper cultivation practices. It may also produce dark green translucent spots on the stem nodes and gradually break. This morbidity manifests itself as affecting the normal growth and viewing of plants, but it can also be fatal. However, there are several differences in rot disease that are commonly referred to: 1. It does not necessarily cause death soon; 2. It often occurs in large areas; 3. No significant effects are caused by spraying.
