In the northern regions, daisies are generally sown at the end of August to the beginning of September; in southern regions such as Jiangsu and Zhejiang, they can be sown in late July. As a commonly used flower arrangement in flowerbeds, daisies have relatively high lighting requirements, and weak lighting may lead to leggy plants. Therefore, special attention is required in production.
According to Bao Qingsong, a technical staff of Beijing Huamu Company, from the daisies sowing stage, special attention must be paid to the control of lighting, even in the summer. Daisies do not need to cover the soil when planting, but the light can not be too strong, need to be properly shaded, can be covered with a thin layer of vermiculite; germination temperature needs to be maintained at 18 °C; substrate humidity is maintained between 80% to 90%, relative air Humidity requires 100%; the pH should be between 5.5 and 6.2, with no need for fertilization. In July and August, the greenhouse environment is mostly in a state of high temperature and high humidity. It is necessary to use the shading nets, fans, wet curtains and other facilities for cooling and cooling.
After plants grow true leaves, the air humidity should be reduced to prevent the substrate from being overly moist and the substrate should have a dry process during the watering interval. When the seedlings have 2 to 3 pairs of true leaves and roots are completed, they can be seedlings.
Moisture control is particularly important at the seedling stage, otherwise seedlings tend to be extremely long. Bao Qingsong said that in order to avoid leggy, first of all to ensure adequate lighting, under the premise of not more than 50,000 lux, the stronger the better, to ensure no less than 10,000 lux. At the same time, it is necessary to strengthen ventilation, control temperature and humidity, and use growth regulators to suppress leggy.
The seedlings can be transplanted onto the pot after the hardening stage. The bowl is made of 12-centimeter nutrient bowls or flowerpots. The matrix requires looseness, good drainage and air permeability, iron chelates and micronutrients, clay content between 15% and 30%, and pH 5.5. 6.2, the EC value is 0.5 to 0.75. After daisies on the basin, the light should be more abundant, at least to ensure 50,000 to 100,000 luxes in winter. In the finished flower production process, top dressing can be performed once a week.
Daisy is susceptible to germs, so when planting, avoid dense planting and keep the environment ventilated and breathable. When disease occurs, 800 to 1000 times of chlorothalonil and 1,000 to 1,500 times of metalaxyl can be used for prevention and treatment; in case of insect pests such as aphids, the infected plants or leaves should be promptly removed.
