A: After the seedbed or planted, the root surface of the pepper seedlings is rust-brown and then gradually rots. The new roots do not grow, causing the stems and leaves on the ground to turn yellow and the plants wilting and dying. This is a physiological disease. This is usually not caused by pathogenic infections, mainly due to excessive watering, insufficient ventilation, long-term ground temperature below 12°C, and poor soil ventilation. If continuous rain occurs, the disease is more likely to occur.
Control measures: 1. Regulate the management of the disease, strengthen seedbed temperature management, conditional use of nursery seedlings, pay attention to increase ventilation, reduce the humidity within the greenhouse. 2. Surface leveling, flood irrigation is forbidden, timely cultivating after pouring, and avoiding too early and too deep for root cultivation. 3. Avoid using large amounts of pesticides such as fungicides, otherwise it will increase the roots. 4. If slight rooting occurs, loose soil should be removed in time to increase ground temperature and enhance soil permeability.
Ulcers is commonly known as gastric ulcer and duodenal ulcer, the formation of ulcers is closely related with gastric acid or pepsin digestion. Ulcer disease is a chronic disease, its seizures were cyclical, episodes and remission of alternating appear, and the onset of abdominal pain has a certain rule. The main cause of ulcers include: 1. Helicobacter pylori infection 2. Bad diet 3. Mental factors 4. Drug stimulation. Many patients with gastric ulcer who have taken non-steroidal anti-inflammatory drug history, these drugs will stimulate our gastric mucosa, causing damage, then it will cause ulcer disease over time. The current anti-ulcer drug is mainly focused on reducing gastric acid and enhance the protective effect of gastric mucosa. In recent years,the research and development of anti-ulcer drug progress is faster, effective drugs have been listed, sales are also rising.
