Matters needing attention in the cultivation of Daisy

Matters needing attention in the sowing stage of daisy

Special attention should be paid to the control of lighting, even in summer.

When sowing daisies, there is no need to cover the soil, but the light should not be too strong, and a thin layer of vermiculite can be covered with vermiculite; the germination temperature should be kept at 18 ℃; the humidity of the substrate should be kept between 80% and 90%, and the relative humidity of the air should be 100%; the pH value should be between 5.5 and 6.2, during which no fertilization is needed.

In July and August, the greenhouse environment is mostly in a state of high temperature and humidity, so it is necessary to use shade nets, fans, wet curtains and other facilities to ventilate and cool down.

True leaf stage of plant

The air humidity should be reduced to prevent the matrix from getting too wet, and the substrate should be allowed to dry out during the watering interval. Seedling refinement can be carried out when the seedling has 2 to 3 pairs of true leaves and the root system is developed.

Matters needing attention in seedling refining stage

Moisture control is particularly important, otherwise it is easy to grow seedlings. In order to avoid apprenticeship, first of all to ensure adequate light, in the premise of not more than 50,000 lux, the stronger the better, to ensure that not less than 10,000 lux. At the same time, it is necessary to strengthen ventilation, control temperature and humidity, and use growth regulators to inhibit overgrowth.

Matters needing attention in transplanting upper basin

Most of the pots use 12-meter diameter nutrition bowls or flowerpots, with loose matrix, good drainage and air permeability, iron chelates and micronutrient elements, clay content between 15% and 30%, pH value from 5.5 to 6.2, EC value from 0.5 to 0.75. After the daisy is on the pot, the light should be more sufficient, ensuring at least 50 to 100000 lux in winter. In the process of producing finished flowers, topdressing can be done once a week.

Pay attention to the control of diseases and insect pests

Daisies are easy to infect germs, so close planting should be avoided and the environment should be ventilated. When aphids and other pests occur, infected plants or diseased leaves should be removed in time.
