The latest breeding methods and matters needing attention of evergreen

Wannianqing, also known as open throat sword, Jiujie lotus, winter not withered, etc., is a perennial evergreen herb of the family Pseudophyllaceae, native to southern China and Japan, and has a long history of cultivation in China. Its Chinese name is "warm herb". It means "warm herb". Potted plants that can be planted indoors are very ornamental. Let's take a look at the breeding methods and matters needing attention of evergreen.

The growth habits of evergreen

Evergreen is widely distributed in China, including East China, Central China and Southwest China, and the main producing areas are Zhejiang, Jiangxi and Hubei. They like to grow in humid places or grasslands under the forest, and like semi-shade, warm, humid and well-ventilated environment. They are not drought-resistant, slightly cold-tolerant, avoid direct sunlight and stagnant water, and can be cultivated in general garden soil, but the slightly acidic sandy loam soil rich in humus, loose and permeable is the best.

The breeding method of evergreen

The main results are as follows: 1. split method: the underground stem of evergreen has strong sprouting power, and the new sprouting and lateral roots of the rhizome can be cut off with a sharp knife in spring and autumn. the wound is smeared with plant ash, planted in a basin, slightly watered, placed in the shade and watered thoroughly after 1 or 2 days. The whole plant can also be poured out of the pot, depending on the size of the plant, divided into several parts, waiting for the wound to dry for a day or coated with plant ash, and the pot can be managed as mentioned above.

2. Sowing method: sub-sowing is usually carried out from March to April. Sow it in the flowerpot containing the culture soil, put it in the shade place temporarily after watering, keep it moist, and germinate in about 25 days under the condition of 25-30 ℃.

3. Cutting method: evergreen can also be propagated by cutting. Cut off the small plant from the base of the plant from April to May in spring, dry the wound slightly, or touch the wound with plant ash and insert it into plain sandy soil. pay attention to shading and moisturizing, and it can take root in about 1 month.

The culture method of evergreen

1. Potted soil: potted Wannianqing used 2 parts of rotten leaf soil, 1 part of garden soil, 1 part of river sand and a small amount of rotten basic fertilizer as culture soil. In order to keep the basin soil moist in the growing season, it should be watered more, rather wet than dry, supplemented by foliar spraying. Control moisture in autumn, wet between dryness and dryness, pay attention to make the basin soil dry in winter, fertilize once a month during the growing period, usually prevent direct sunlight and give shade, change the basin once a year in spring, and the overwintering temperature in winter should not be lower than 10 ℃.

2. Illumination: evergreen likes semi-overcast environment and is afraid of direct sun in summer. For greenhouse cultivation, more than 60% should be shaded in spring, summer and autumn, and 40% in winter. The light is too strong to be burned by the sun, and the light is too weak to blossom and bear fruit.

3. Temperature: the suitable growth temperature of evergreen is 15: 18 ℃. Dormant in winter into the greenhouse, put in the sunny place, the temperature is kept above 10 ℃, the lowest temperature can not be lower than 5 ℃. The Yangtze River basin can overwinter in the open field, and although the leaves have frost damage, they can still sprout new leaves the following year.

4. Fertilizer and water: liquid fertilizer is applied every 10 to 15 days in the growing season. In summer, we should strengthen ventilation, prevent heat and cool down, and provide adequate water supply, and often keep the basin soil moist and the air humidity of the surrounding environment. It should be watered once or twice a day in summer. Reduce watering and stop fertilizing in winter.

5. Plastic surgery: in order to maintain the good shape of the plant and improve the ornamental value, the lower yellow leaves, residual leaves and some old leaves should be pruned in time with the growth of the plant. When raising in the family pot, you can wipe the leaves with a soft cloth dipped in beer, which can not only remove the dust, but also increase the nutrition to the leaves, making the leaves bright green and clean.

Matters needing attention in evergreen culture

1. Evergreen is a fleshy root plant, stagnant water is easy to cause waterlogging, watering too much, easy to cause rotten roots.

2. If the leaf tip is yellow and scorched, or even the whole plant wilts in winter, it is mainly caused by the inability of the roots to absorb water and affect the growth.

3. Keep the evergreen in a warm, moist and semi-overcast environment. The summer growth is exuberant, should be placed in the shade place, lest the strong light irradiates, otherwise, easy to cause the leaf dry tip scorched edge, affects the ornamental effect.
