Detailed Explanation of Disease Prevention and Control Techniques for Ceylon Spinach
The main diseases of Ceylon spinach (Malabar spinach) include brown spot disease (also known as fish-eye disease), red spot disease, snake-eye disease, and sun scald, among others.

Infected leaves initially show small, sunken, purplish-red, water-soaked round spots, which gradually expand. In severe cases, the spots can number more than a hundred, merge with one another into large lesions, and cause premature leaf aging.

Methods for Raising Seedlings and Transplanting Ceylon Spinach (Malabar Spinach) and Key Technical Points
Prepare the seedbed well, sow dry seeds, and seedlings emerge in 3 to 5 days at a suitable temperature of around 28°C; if the soil temperature is on the low side, the seeds should be pre-germinated before sowing. During the seedling stage, keep the temperature appropriately low, and transplant when the plants have 4 to 5 true leaves. For harvesting tender shoots, use a row spacing of 20 to 25 cm and a plant spacing of 15 to 20 cm; for growing on trellises to harvest tender leaves, use a row spacing of 60 cm and a plant spacing of 25 to 35 cm, keeping...
