Technical points of cold water flower cultivation
Technical points of cold water flower cultivation:
Cold water is warm and humid, and it is suitable for loose and fertile sand. The growth is suitable for 15 °C to 25 °C, and the winter temperature should not be lower than 5 °C.
Its specific management:
First, the light management cold water flower is a kind of indoor flower with beautiful leaf color, very resistant to yin, but prefers sufficient light, and should avoid direct sunlight. Summer pots are placed in the north window, and winter is placed in the south window. The light is too dark, the color of the leaves will fade; if the sun is too strong, the leaves will be burned.
Second, the management of fertilizer and water masters the principle of wet management, the basin soil remains dry without cracking, and it is better to run without wet. In summer, the water is often sprayed onto the foliage to keep the leaves clean and shiny. In winter, there is less water spray on the leaves, otherwise black spots will appear on the leaves, and even black rot will occur. The growth period is about two or eighty percent of water, and that the plant is robust. After the autumn, phosphorus and potassium fertilizers should be added to strengthen the stems and prevent lodging.
Third, breeding multi-use cutting method, can be carried out in spring and autumn. The amount of the family is less than that in May, the top of the stem is used for the ear, and the medium is made of river sand or vermiculite. Under suitable temperature conditions (20 ° C to 25 ° C), the roots are rooted for about 10 days. When the shoots are extended by 3 cm to 5 cm, use a sandy pot. Pour the root water and transfer it to normal management.
It is usually propagated by cuttings, and it can also be propagated by ramets.
1. Cutting propagation: cuttings can be carried out in spring and summer. Summer high temperature season is not suitable for cutting, winter cuttings grow slowly. Select the growing and fulling branches, cut the apex of the stem 5 to 8 cm long as the cuttings, retain the apex of several leaves, directly insert into the sand bed with vermiculite or plain sand as the substrate, or insert the potting soil mixed with peat and soil. In the middle, the depth of the soil should not exceed 2 cm. Placed in the semi-shade, the soil temperature is maintained at 18 ~ 20 ° C, spray water with a watering can when drying, rooting can take about 2 to 3 weeks, after 1 to 2 months can be transplanted or above the basin.
2, ramets breeding: cold water flower cluster is very strong, can be combined with the turn basin for soil, the whole pier column plexus is divided into several separate upper basin, while the old stem is short cut, retaining stem base 2 to 3 knots, survive After the axillary buds can germinate quickly and new collaterals are produced.
Water: Hi moist, keep the soil moist in the summer, spray the leaves and water every day to keep the leaves bright.
Fertilizer: 4-9 months, fertilize once every half month.
Soil: Loose soil with good drainage and can be mixed with loam, river sand and humus soil.
Warm: Hi warm, grow at a suitable temperature of 15-25 ° C. Winter in winter, the temperature is around 5 °C.
Light: more resistant to yin, avoid the sun, hi scattering light.
Fourth, other management will change the basin once a year. When the old plants are scattered and the ornamental value is reduced, the seedlings are regenerated by cuttings to enhance the ornamental value. At the same time, it can also reduce pests and diseases. In the case of poor ventilation, it is vulnerable to mites. When the potting soil is muddy for a long time, the roots often rot, so care should be taken to properly control the water and soil.
