breeding method
land
Potted small beautiful flowers need to choose a suitable substrate, which can be mixed with garden soil, cinder and fine sand, or add some humus soil. Spread broken tiles on the bottom of the flowerpot as a drainage layer, and then add some base fertilizer to the culture medium.
Light and temperature
The growth of small flowers needs sufficient light, and the light should not be less than 6 hours a day, and too much shading is not allowed to avoid poor growth. Direct light can be given to dahlias in spring, autumn and winter, but direct light should be avoided as much as possible in hot summer and maintained in a bright place. As far as temperature is concerned, Xiao Lihua likes cooler environment and is afraid of heat. When the weather is hot and sunny in summer, it is necessary to shade the sun or spray water to cool down. It is also not resistant to frost and cold. When the temperature drops below 10℃, it will go into hibernation. The suitable growth temperature of Dahlia is between 65438 05℃ and 28℃.
Water and fertilizer management
Small beautiful flowers have low requirements for water and fertilizer. Generally, water more in summer, less in spring and autumn, keep the soil dry and wet, avoid water accumulation in the basin, and pay attention to drainage in rainy season. When fertilizing, apply sufficient base fertilizer when planting. Apply dilute liquid fertilizer every 10- 15 days during the growth period, and apply some 1%-3% potassium dihydrogen phosphate when flowering to promote flowering.
Matters needing attention
prune
In the process of cultivating small beauty flowers, pruning can be carried out in order to control the flower pattern and promote flowering. In the growing period, frequent pinching can make small beautiful flowers more branched and dense. In the process of growth, some dead leaves and diseased leaves can be cut off to promote the healthy growth of Dahlia.
breeding method
The propagation of Dahlia mostly adopts ramet propagation and ball propagation, and cutting propagation can also be used.
Eliminate pests and diseases
Diseases and insect pests of Dahlia are not common, but there are powdery mildew, brown spot, virus disease and moth larvae, which need to be found in time and prevented in advance.
