Velvet bamboo taro is also known as zebra bamboo taro. It is named "velvet" because its leaf shape is very similar to the velvet of swan. With wide green leaves and zebra shaped dark green stripes, it is a very beautiful foliage plant with high ornamental value. It is very suitable for potted plants in families, hotels and public places. So, how is goose down cultivated? What matters should we pay attention to when raising goose down? Please read down with me with your questions!
Breeding methods of velvet: the best breeding time: the breeding of velvet is usually carried out in April to may in spring or at the end of autumn;
The best growing soil: the best growing soil for goose down is rotten leaf soil or peat soil with good fertility and drainage;
Requirements for growth and humidity: Goose's long life requires higher air humidity, preferably humidity of more than 80%, spray several times in the morning and evening, but the pot soil should not be too wet, otherwise it will easily damage the roots.
The optimum growth temperature was 18-25 ℃, 21-27 ℃ from March to September, and 18-21 ℃ from September to next March. The winter temperature should not be lower than 13 ℃ and the summer temperature should be higher than 35 ℃. Otherwise, the growth of the stem and leaf would stop or freeze to death.
The best growth light: the light should not be too strong, a little shade in summer, semi shade environment is better, the leaf color is fresh.
The cultivation method of velvety bamboo taro the precautions of raising velvety: watering points: the reaction of velvety to water is very sensitive. In the growing season, the basin soil must be watered sufficiently to keep it moist. However, if the soil is too wet, it will cause root rot or even death, which should be paid special attention to.
At the same time, if the air humidity is small, the leaves curl immediately, and the response is very sensitive. Indoor cultivation, air humidity must be maintained at 70% - 80%. In winter, the leaves were kept a little dry, and the leaves were easy to turn yellow and wither if they were too wet.
Fertilizer application: fertilize once every half a month during the growing period, and properly add phosphate fertilizer.
Basin soil replacement: goose down is changed every autumn. The basin soil can be mixed with culture soil, peat soil and coarse sand.
Breeding points: goose down is mainly propagated by ramet method and tissue culture method.
Vigorous plants can be divided once every 1-2 years. When changing pots, the plants should not be planted too deep. The roots should be planted into the soil, otherwise the growth of new buds will be affected. Tissue culture is generally used in large-scale propagation.
1. Ramet propagation: from April to may in spring or at the end of autumn. During the operation, the over dense plants are lifted out from the basin, the healthy and neat plants are separated, potted separately, watered fully, and maintained in the shade. But it is easy to damage the root in early spring, which affects the survival rate. Generally, ramets should not be carried out too early, and it is more appropriate to do so when the temperature is relatively stable. Each plant should have more than 3-4 small plants, and try to retain a certain amount of original soil, so as not to affect the growth and formation of plants. The cultivation soil was composed of loose rotten leaf soil or peat soil, 1 / 3 perlite and a little sand.
2. Tissue culture propagation: petioles of tender stems or undeveloped leaves are often used as explants. After regular disinfection, petioles and young stems were cut into 3 mm segments and 3 mm segments under aseptic conditions, and inoculated on MS medium supplemented with 5 mg / L 6-BA and 0.02 mg / L NAA to induce callus and adventitious buds. Adventitious buds could differentiate into adventitious roots on MS medium supplemented with 0.5 mg / L NAA. The survival rate of rooting seedlings was more than 95% when they were transplanted in peat and perlite medium with high air humidity.
Pest control:
Goose down is mainly damaged by leaf spot and leaf blight; It can be prevented by spraying the same amount of Bordeaux solution with lime.
The main pests of goose down are: whitefly, spray with 25% imidiphos EC 1000 times.
Calathea zebrine
