1. Temperature control
Garland chrysanthemum is a warmth-loving crop. The suitable temperature range for its growth is around 18 degrees, but garland chrysanthemum is generally planted after the Beginning of Spring, when temperatures have not yet fully risen. So if temperature control is not handled well, a late cold spell can easily occur, leading to weak seedlings or even dead seedlings. Therefore, after sowing, we should promptly cover the sowing surface with plastic film, press the film down firmly, and take good measures to protect against cold and preserve warmth to promote seed germination and seedling emergence. Wait until the temperature gradually rises, then uncover the plastic film, but when the temperature is too high, also pay attention to cooling it down in time.
2. Thinning seedlings and weeding
After the seedlings emerge, observe the growth of all seedlings. If weak or dead seedlings are found, replant them in time. Then, when the seedlings grow to about 9-11 cm, do the thinning work well. Determine the thinning spacing according to the different varieties. When thinning, remove excess weeds in the field, because weeds have far stronger growth ability than seedlings, and weed growth also requires a large amount of nutrients and water. If weeds are not removed in time, the nutrients will all be snatched by the weeds, causing the growth of the seedlings to be hindered.
3. Water and fertilizer management
Water and fertilizer are indispensable for the growth of garland chrysanthemum. Strengthening water and fertilizer management can increase its growth speed and resistance. After the seedlings emerge, water them in time to promote water absorption by the seedlings. The frequency and timing of watering should be determined according to the growth condition of the seedlings, keeping the soil moist and providing sufficient water for the seedlings. Then observe the soil fertility and the growth stage of garland chrysanthemum, and apply additional fertilizer at the appropriate time. Generally, about two weeks before harvest, apply a quick-acting nitrogen fertilizer once. The amount used depends on the planting area. When fertilizing, pay attention to the use of nitrogen fertilizer and do not use too much, to prevent excessive vegetative growth of garland chrysanthemum.
4. Pest and disease control
Pest and disease control is work that must be done well throughout the entire growth period of garland chrysanthemum. The harm caused by pests and diseases to garland chrysanthemum is by no means slight; in severe cases, it can cause total crop loss. The more common diseases include damping-off and leaf spot, while pests include cabbage webworm and aphids. Therefore, field management should be strengthened, and preventive measures for various pests and diseases should be done well. When signs of pests or diseases are found, immediately identify the specific pest or disease, then carry out corresponding treatment measures, and reasonably use various agents and insecticides. However, pay attention to the dosage, because excessively high drug concentration can also inhibit the growth of garland chrysanthemum.
