What should be noted when cultivating garland chrysanthemum in a plastic tunnel? We also ask knowledgeable readers to help explain.Zhongdiwang has compiled the four key points for cultivating garland chrysanthemum in a plastic tunnel in autumn, listed in detail below for readers' reference.
Key point one, sowing time for garland chrysanthemum:
Generally, garland chrysanthemum seedlings emerge 3-4 days after sowing, but if within 3-4 days after sowing the weather is entirely sunny and the temperature exceeds 32°C, then seedling emergence will be relatively difficult.
Therefore, before sowing, you must check the weather forecast. It is best to ensure that after sowing garland chrysanthemum will encounter 1-2 days of cloudy weather or slightly lower temperatures, so as to ensure normal seedling emergence.
Key point two, sowing rate for garland chrysanthemum:
If the weather is cold and cool, only 6-7 jin of seed is used per mu of garland chrysanthemum, but as the temperature rises, to prevent seedling death, the sowing rate should be appropriately increased, using 8-9 jin per mu.
Key point three, watering garland chrysanthemum:
After sowing, garland chrysanthemum generally only needs three waterings before harvest. The first watering immediately follows sowing. The second watering is generally done about 10 days after seedling emergence. However, the timing of the second watering is not fixed; it depends on the market price. If the market price is good, the second watering can be done a few days earlier to bring it to market sooner; if the market is poor, it can be delayed a few days to delay marketing. The third watering is done one day before harvesting garland chrysanthemum, to help improve quality.
Key point four, pest and disease control for garland chrysanthemum:
Generally speaking, after seedling emergence garland chrysanthemum is highly susceptible to rhizoctonia rot and damping-off, so immediately after seedling emergence spray 15% hymexazol aqueous solution at 450 times dilution for control.
