Evergreen (Rohdea japonica (Thunb.) Roth), alias Baihe car, is a perennial evergreen herb, native to southern China and Japan. It is an excellent ornamental plant loved by everyone. It has a long history of cultivation in China. Its Chinese name means "warm herb". Potted plants that can be planted indoors are very ornamental.

Perennial evergreen herbs, without stems above ground. The rhizome is thick and short, yellowish-white, articulate, with many slender fibrous roots on nodes. The leaves are clustered from the rhizome, thick, lanceolate or banded, 10-25 cm long and 2.5-5.5 cm wide, with the edge slightly pleated, the base narrowing to the shape of a petiole, dark green above, light green below, many parallel veins straight out, and the main vein thicker.

Scape from leaves in spring and summer, 10-20 cm long; flowers numerous, clustered at tip in short spikes; perianth 6, light green-white, ovate to triangular, head tip, base broad, lower part healed into disk; stamens 6, sessile, anthers long-elliptic; ovary globose, style short, stigma 3-lobed. The berry is globose, orange-red, containing 1 seed.

Evergreen, sexual preference for warm, humid and semi-shady environment, avoid summer glare. The key to raising evergreen is to avoid direct sunlight when the summer weather is hot and the sun is strong. Otherwise, it is easy to cause dry tip and scorched edge of leaves or even withered and yellow, affecting the ornamental effect. So evergreen is perfect for raising in the bedroom. It should be noted that the indoor temperature in winter should be between 6-18 ℃; in winter, the air should be kept moist and the soil slightly moist, the dry air in the bedroom should often spray water to the leaves, and the leaves should be sprayed and washed once a week to prevent the leaves from being polluted by smoke and dust.

Evergreen sex likes a warm, humid and semi-shady 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. Therefore, after leaving the room in early spring, it is appropriate to put it in a shaded scaffolding or under the eaves or balcony.

Evergreen for the fleshy root system, the most afraid of stagnant water, therefore, can not be watered, otherwise it is easy to cause rotten roots. The basin soil is usually irrigated with the right amount of water, so that the basin soil is not dry or irrigated, it is better to be dry than too wet. In addition to keeping the basin soil moist in summer, watering in spring and autumn should not be too frequent. But must keep the air moist, such as dry air, but also prone to dry leaves and other adverse phenomena. In summer, water should be sprinkled on the ground around the flowerpot every morning and evening to create a humid microclimate. Should also pay attention to guard against heavy rain, especially in the flowering period can not be caught in the rain, should be placed in the shade dry and ventilated place.

During the growth period, left every 20 days

The right applies a mature liquid fertilizer; the growth is more exuberant in early summer, and the liquid fertilizer can be applied once in about 10 days, and a small amount of 0.5% ammonium sulfate can be added to the topdressing, which can promote its growth better and the leaf color is dark green and bright. From June to July, 0.2% dihydrogen phosphate solution is applied every 15 days or so to promote flower bud differentiation so as to better blossom and bear fruit. In addition, a few pieces of the old leaves on the periphery of the adult plant should be cut off before and after the Beginning of Summer to facilitate the germination of new buds, new leaves and scape.

In winter, evergreen needs to be moved indoors to survive the winter, placed in a place with sufficient strong light and good ventilation, and the temperature is maintained at 6-18 ℃. If the room temperature is too high, it is easy to cause excessive growth of leaves and consume a lot of nutrients, resulting in weak growth in the following year and affecting normal flowering and fruiting. If evergreen leaves tip yellow coke in winter, or even the whole plant wilt phenomenon, mainly because the roots can not absorb water, affecting the growth. Therefore, in winter, it is also necessary to keep the air moist and the basin soil slightly moist, generally watering 1-2 times a week. In addition, the leaves need to be sprayed with warm water once a week to prevent the leaves from being polluted by smoke and dust, so as to keep the stems and leaves fresh green and green in four seasons.

Evergreen leaves are evergreen all the year round, hence the name. Evergreen is also popular among indoor plants, so how to raise it? Let's learn about the breeding methods and precautions of evergreen as well as the pictures.

I. the culture method of evergreen

1. Soil: evergreen should be placed in spring as far as possible when turning soil and changing pots. Evergreen cultivation is not very demanding on the soil, but it is most afraid of stagnant water, no matter when choosing land or potted plants, the most taboo is clay or alkaline soil. Most of the potted plants are planted with rotten leaf soil mixed with Gaza, and the soil is also divided into different areas. the south can choose potted or open field cultivation, while the north needs to be cultivated in the greenhouse, changing the new soil once a year and changing the pot once every year. When changing the basin, add new fertile soil appropriately.

two。 Light and temperature: evergreen is suitable for semi-overcast environment, afraid of direct sun in summer. If it is a greenhouse cultivation, it should be shaded by more than 60% in spring, summer and autumn, and 40% shade in winter. The light is too strong to be burned, and the light is too weak to blossom and bear fruit. Adapt to the environment where the temperature is 15-18 ℃. Winter is a dormant period. You can put it indoors and put it in a sunny place. The temperature can be kept above 10 ℃, and the lowest temperature can not be lower than 5 ℃. The Yangtze River valley can be cultivated in the open field for the winter, and the leaves may freeze bad, but new green leaves can still be shown again in the coming year.

3. Fertilization and watering: evergreen growth season every 10 murals 15 days to apply fertilizer, preferably liquid fertilizer, summer to strengthen ventilation, heat prevention and cooling, is the need for adequate water supply period, often maintain the moist basin soil and the surrounding environment air humidity, summer should be watered twice a day, in winter is to reduce watering frequency, stop fertilization.

4. Pruning: the purpose of evergreen pruning and shaping is mainly to maintain the good shape of the plant and make it pleasing to the eye. with the growth of the plant, if yellow leaves and residual leaves appear in the lower part of the plant, some masters should be pruned in time. When raising in the family pot, you can wipe the leaves with some beer on the reef with a soft cloth, which can not only remove the dust, but also add nutrition to the leaves and keep the leaves bright green and clean.

II. Matters needing attention in evergreen culture

1. Evergreen is a kind of flower that likes to be warm and humid, resistant to shade and afraid of cold. Keep it outdoors in summer and need to build a shed for shade. With strong sunlight, the leaves are easy to turn green and white, and the edges of the leaves are also easy to zoom. The optimum temperature for the growth of evergreen is 20 ℃ 30 ℃. In winter, the indoor temperature should be kept between 12 ℃ and 15 ℃, and the lowest temperature should not be lower than 7 Mel. The leaves below 7 Mel should be yellowed and shedding, and the whole plant would die in severe cases.

2. During the growing season, evergreen would rather be wet than dry. If the temperature is above 25 ℃, spray water to the leaves frequently. After autumn, watering should be controlled so that it is suitable to see dry and wet. In winter, it is appropriate to dry.

3. Evergreen has strong fertilizer tolerance and appropriate amount of fertilizer. During the growing season, 20% cake fertilizer water or 1% compound fertilizer solution should be applied once every 15 murals for 20 days, and fertilization should be stopped in winter. It should be shaded at noon in spring, autumn and summer, and put it in a bright place when growing indoors. But keep plenty of light in winter.

The above is the introduction of evergreen breeding methods and matters needing attention, everyone hurriedly to plant a few pots, put at home can not only watch, but also purify the air.

Breeding methods and points for attention of evergreen how to raise evergreen

Evergreen, Silver Queen, famous Jian, open throat sword, winter does not wither, winter does not wither grass, thousand years of grass, and so on, are perennial herbs. How to raise evergreen? Next, let's talk about the breeding methods and matters needing attention of evergreen.

The culture method of evergreen:

1. Planting: planting in spring or turning over the basin to change soil. Not strict with the soil, but afraid of stagnant water, avoid hard clay and alkaline soil when planting or potted. Pots are generally planted with rotten leaf soil and mixed soil from Gaza.

2. Light and temperature: 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. Huawang No. 3 can be used to promote flower bud differentiation, more flowering and more fruit. 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.

3. Watering and fertilization: when liquid fertilizer is applied every 10-15 days in the growing season, combined with spraying new high-fat film to enhance fertilizer efficiency, the flowers and leaves will flourish and be brilliant. 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. Water 1-2 times a day in summer. Reduce watering and stop fertilizing in winter.

4. Shaping and pruning: 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. The cut should be smeared with callus preservative film to prevent bacterial infection and still sprout new branches and blossom again in late autumn. When raising in the family pot, you can wipe the leaves with a soft cloth dipped in beer and spray Zhuangtuanling, which can not only remove the dust, but also add nutrition to the leaves, making the leaves bright green and clean.

Matters needing attention in evergreen culture:

1, pay attention to when turning the soil, we should pay attention to the early transplanting, water can not be watered too much, otherwise the root will die because of too much water. Potted soil is best to use corrosive soil, which is suitable for warm cultivation. Be sure to remember that you can change the soil every 2 years.

2. Evergreen is a semi-shade plant, the demand for light is not high, but can not be without light, especially in summer can not have too much light. In winter, you should pay attention to basking in the sun, but the temperature should not be lower than 10 degrees Celsius. Otherwise, the flowers are prone to frostbite.

3. Evergreen if the leaves turn yellow or the edges of the leaves are curled, it may be caused by lack of water or no light.
