Breeding | about a beautiful African chrysanthemum

Soil

Gerbera is sensitive to water and should use a medium with good permeability and drainage, preferably a mixture of peat and perlite. The pH value is 5.5-6.0 and the EC value is 0.7-1.0, which is beneficial to the absorption of trace elements.

Watering

Potted gerbera is very sensitive to water, so it must be watered at the right time, in the morning or evening, and at night to make the plant relatively dry. When the plant begins to grow roots, it must be watered from the bottom, which can be infiltrated at the bottom; it can be watered from the top of the plant during high temperature, but care should be taken to prevent fungal mildew from the center of the plant.

Sunshine

The most suitable sunshine length during the growth of African chrysanthemum is 11-13 hours, so it can be replenished by artificial light in low light. The general requirement of artificial supplementary light is 3500 to 4000 lux per square meter.

Temperature

The most suitable temperature for the growth of African chrysanthemum is between 15 ℃-25 ℃, the highest is not higher than 30 ℃ and the lowest is not less than 13 ℃. High temperature will affect the normal flower bud differentiation, and low temperature will cause plant death.

Fertilizer application

African chrysanthemum is a perennial flower that likes fertilizer. There is a great demand for fertilizer. The proportion of nitrogen, phosphorus and potassium is 15:18:25. Special attention should be paid to the supplement of potash fertilizer. 2.5 kilograms of potassium acid and 1.2 kilograms of ammonium nitrate or ammonium phosphate per mu, once every 5-6 days, once every 10 days. If the plant is semi-dormant caused by high temperature or low temperature, fertilization will be stopped.

Insect pest

The diseases of African chrysanthemum include leaf spot, powdery mildew and virus. Leaf spot disease was sprayed with 1000 times of 70% methyl topiramate wettable powder or 50% carbendazim wettable powder. Powdery mildew was prevented and treated with 1500 times of thiophanate methyl or 1000-1200 times of wettable powder, once every 7-10 days, and sprayed 2-3 times continuously.

Pruning

The lower leaves of the basal leaf clusters of African chrysanthemum are easy to wither, yellow and senile, which should be removed in time, which is not only beneficial to the germination of new leaves and flower buds, but also conducive to ventilation and enhance plant growth. In addition, if the branches and leaves of the plant are too luxuriant to cover each other, some of the leaves can be removed properly.
