Planting technology of African chrysanthemum

Sowing and raising seedlings: the seeds are watered behind the hole plate, sprayed with fungicides, and then cultivated in the greenhouse. | | colonization: the best planting time is from late March to mid-April in spring. Pay attention to the planting density. | | | cultivation management: do a good job in the management of temperature, light, water and fertilizer, thinning leaves and buds, and pest control.

Reproduction of Gerbera:

1. Ramet

It is suitable for some African chrysanthemum varieties with strong tillering ability. Ramets are mostly carried out from March to May. The new ramet must have buds and roots, so it should not be too small. When ramet, the plant was cut longitudinally along each ramet with a sharp weapon, and then the separated ramets were dug up and transplanted after the wound healed.

two。 Cuttage

It is best to do it in March or April. Strengthen the management of cuttings can blossom in the second half of the year, summer cuttings will not blossom until the following spring. The mother plant should use the plant that has grown for more than one year, dig up the strong plant, wash the mud from the root, remove the leaves, cut off the growth point, carefully retain most of the thick rhizome, and then plant the plant in the planting box. When the temperature is 22-34 ℃ and the air humidity is 70%-80%, the branches can be removed for cutting after 10-14 days. In order to speed up the rooting of cuttings, the cuttings can be slightly wet in 0.2% potassium permanganate solution (disinfection and disease prevention), and then the base can be inserted into commercially available rooting powder or 500 mg / L naphthylacetic acid solution before cutting.

3. Sowing seeds

Spring sowing from March to May and autumn sowing from September to October. The sowing method of small seeds was carried out in the laboratory, the optimum temperature for germination was 18-22 ℃, and germinated 7-10 days after sowing. After germination, the seedlings were moved to the sunny place, and the seedlings were divided after the cotyledons were fully developed. the seedlings could be planted when they grew 2 true leaves. The best time for planting was in May and June, and flowering could be seen in 2-3 months after planting.

African chrysanthemum is a plant native to Africa and is a semi-cold-tolerant plant. Everyone should pay attention to the work of preventing cold and keeping warm in winter.
