Gerberajamesonii, a member of the genus Gerbera of the Compositae, is a perennial herb that is known as "gerbera" because it is native to Africa. The leaves are deeply feathered and clustered at the base of the plant, a bit like a dandelion. Pedicel above the leaf surface, a stem only open a single flower, is a flower head. Petals resemble the long tongues of a bird. They are born around the flower's core. They are as big as a cup, and they resemble a radiant sun. The shorter plants, about 30 cm in height, are the latest high-quality potted plants. Their varieties are novel and have great market potential. It also allows growers to obtain greater profit margins. Its rich colors are rose, yellow, dark rose, pink, orange, bright yellow and other colors. Each plant can open 4-8 at the same time, each flowering flower is 7-10 days. The Jaguar is a novel potted variety with high uniformity, large flowers and stout stems. Gerbera seeds are larger, about 300 grains per gram. Seedling trays can be used for sowing. The sowing medium should be light and loose culture soil with a pH of 5.5-6.5. After sowing, less soil is needed to keep the soil moist. It needs to maintain for about 20 days and it takes 7-10 days to emerge. Seedlings need to be sprayed with fungicides to prevent diseases and ensure the healthy growth of seedlings. Seedlings can be transplanted into seedling trays 2-4 weeks after seedling emergence. According to seedling plate size, planting density is about 400 strains per square meter. After the transplanted seedlings, the pots can be put on 4-5 weeks. 13-15 cm diameter pots can be used, and the soil used in the upper pot should be light and well drained. Too heavy soil can cause root growth to be blocked. Suitable formulas are: 25% peat; 35% peat; 20% coarse perlite; 20% coarse (1-2 cm) peat; sometimes you can add some garden soil, not too much. The pH of the soil is 5.0-5.5 and it needs to be supplemented with trace elements. Gerbera is very sensitive to iron deficiency. The temperature of the seedlings during the growth period is 20-22 °C. When the plants are put on the pot, the growth temperature can be adjusted to the temperature of 18 °C and the night temperature of 15 °C. The temperature difference between day and night has great influence on the formation of flower buds. Do not appear negative temperature difference between day and night during temperature adjustment, otherwise it will delay flowering. Temperatures below 10°C stop growing; at temperatures above 24°C, the plants grow longer and flowering is postponed. Gerbera flowers need strong light, such as insufficient or weak light, can cause excessive elongation of the stem, affecting the type of plant, if there is a lack of light caused by the stem is too long, can not use chlormequat, chlormequat only It can be used before flowering stems are formed at the seedling stage. During the cultivation process, special attention should be paid to drainage to avoid water in pots and soils. Excessive water can cause root diseases and it is advisable to keep the soil relatively dry. Watering management should be carried out in the morning so as to prevent the plants from being in wet soil in the dark night. The air humidity is 70-80% and cannot be higher than 80%. Gerbera is a very hilarious flower, especially for potash. Excessive nitrogen fertilizer will delay flowering and reduce flowering. Gerbera grows in accordance with standard environmental conditions and takes 4-5 months from budding to flowering. During the cultivation and management process, the following common problems are encountered: abnormal flower type due to excessive temperature; young leaves appear regular dark purple; only main veins are green, often due to calcium deficiency; their seedling growth is retarded, and the seedlings are tender and purple. Often due to nitrogen deficiency; there are anthrax along the leaf margins, chloasma on the leaf blade, lighter, chlorosis, or brown in the old leaves; lack of potassium in the presence of short stems and small flowers; iron-deficient leaves Yellow, pay attention to the lack of iron in the soil from the seedling stage. Gerbera flower color is rich, decorative, potted performance is good, large flowers, short stems, early flowers, welcomed by the majority of customers.
