Jin Chahua is an ornamental plant, which is often used for greening and garden decoration. How to cultivate it in Jin Chahua will be introduced in detail.

Jin Chahua is a traditional famous flower in China, and also a world-famous ornamental plant, which belongs to the rare flowers and trees under national first-class protection. It is distributed in Guangxi and other places, generally growing in evergreen forests in mountainous areas, and the soil has no lime. Besides high ornamental value, it can also be used to treat diseases.

Camellia belongs to Camellia of Theaceae, and is a twin sister with tea, camellia, Nanshan tea, camellia oleifera and camellia. The flowers of Camellia chrysantha are golden and dazzling, as if coated with wax, glittering and translucent and oily. Camellia is born alone in the axils of leaves. When flowering, it is cup-shaped, pot-shaped or bowl-shaped, which is beautiful and generous. In the past, people have never seen a golden variety. 1960, Chinese scientists first discovered a camellia, named camellia, in Nanning, Guangxi. Foreign countries call it the magical oriental tea, and it is known as the giant panda in the plant world and the queen of the tea family.

Potted camellia:

1. The size of the pot should be adapted to the proportion of seedlings. It is best to add pine needles cut by l/2-l/3 Igf into the garden soil, and then apply them after 1 year decay, and the effect is better.

2. The pot feeding time is winter 165438+ 10 or February-March in early spring. Pot feeding should be stopped near germination stage and avoided in high temperature season.

3. When the seedlings are newly put into the pot, the water should be poured enough and the bottom of the pot should be permeable. Drink water in moderation at ordinary times.

4. Shading and cold protection: Camellia likes to be warm and humid, and supercooling and overheating are not conducive to its growth and development. Generally, greenhouse cultivation is not needed. Sufficient sunshine should be given in spring and rainy season, otherwise the branches will grow thirsty, which will easily cause black spot disease and scale insect damage, and the branches will also be prone to moss medicine, leading to plant aging and death. In summer and autumn, it is necessary to shade and cool down in time. In winter, the natural cooling of mules or long-term low temperature will cause the basin soil to freeze and the plants to freeze to death, so anti-freezing measures must be taken in time. If potted plants overwinter indoors, it is advisable to keep them at 3-4℃. If the temperature exceeds 16℃, it will promote early germination, and even cause defoliation and bud drop in severe cases. The fertilization, pruning and pest control of potted camellia are basically the same as those of open field cultivation.
