Culture method of Rainbow Bamboo Taro

Rainbow bamboo taro, also known as red rose bamboo taro, red back bamboo taro, big peacock bamboo taro, etc., is a perennial evergreen herbaceous foliage plant of the family Amorphophallus family. It is native to Brazil and is introduced and cultivated in China. Because the plant is shade resistant, it is very suitable for family indoor decoration and beautification, greening, and has high breeding and ornamental value. Let's take a look at the breeding methods of rainbow taro.

Growth habits of Rainbow Taro

Rainbow bamboo taro like high temperature and humid environment, avoid sun exposure, not heat-resistant, avoid high temperature, not cold-resistant. Avoid drought, the suitable temperature for growth is 18-25 ℃. The plant is short and tufted, and the tillering ability is poor. The petiole is directly born on the underground stem and has no main root, so it is appropriate to choose a shallow basin with a wider pot body when potted. Slightly acidic rotten leaf soil as cultivation medium is most beneficial to rhizome growth and the formation of luxuriant plants.

Propagation method of Rainbow Bamboo Taro

1. Ramet: rainbow bamboo taro is generally propagated by ramets, which is the best when the temperature is about 20 ℃ in spring, but it can also be carried out throughout the year as long as the temperature and humidity are suitable. When propagating, use a sharp knife to cut the root mass with stem and leaf buds, a small amount of reproduction can put the cut root mass with stem, leaf and leaf bud directly in the mud basin, when propagating in large quantities, it should be placed on the seedbed, and when the temperature and humidity do not meet the requirements, the film should be covered with a thin film. Be sure to make the temperature in the film reach 20: 28 ℃ and the humidity above 80%.

2. Cuttage: cutting propagation generally uses top shoots, cuttings are 10-15 cm long, leaves are reserved 1/3 or 1/2 depending on leaf size, cuttings are treated with 500ppm NAA for 2-3 seconds, and they can also be treated with indoleacetic acid, indolebutyric acid and ABT rooting powder. After the cuttings were treated, they were inserted into the seedling bed with a row spacing of 5 × 10 cm. It is covered with thin film bow shed, and the management method is the same as ramet propagation. Cutting propagation can be carried out at any time when the temperature is not less than 20 ℃, and the cuttings take root in 30-50 days, but the survival rate of cutting is not as high as that of ramet propagation, generally about 50%.

Culture method of Rainbow Bamboo Taro

1. Soil: rainbow taro prefers well-drained, fertile, loose slightly acidic rotten leaf soil or culture soil. The basin soil should be composed of humus soil, compost and 3 river sand or sawdust, and the pH value should be 5.5-7.2.

2. Temperature: the optimum growth temperature of Rainbow Taro is 20: 25 ℃, the winter temperature is not less than 15 ℃, and the aboveground parts die gradually below 10 ℃.

3, lighting: rainbow taro avoid sun exposure, summer and autumn to shade, the sun is too strong, the leaf color is easy to show old and dry, the light is too weak, the leaf quality becomes thin and dull, loses the sense of beauty. There should be plenty of sunshine in winter.

4. Moisture: rainbow taro likes a humid environment, and the basin soil should always be kept moist during the high temperature period in summer and autumn, otherwise there will be scorched leaf edges and poor growth. In addition to watering once a day, spray should also be strengthened to keep the air relative humidity at 85-90%.

5. Fertilizer: rainbow bamboo taro is applied thin fertilizer once a week during the growing period, and the concentration is equivalent to adding 3 grams of urea per kilogram of water, and then applying 3 grams of urea plus 1 gram of potassium dihydrogen phosphate, or similar concentration of nitrogen, phosphorus and potassium compound fertilizer, it is also possible to apply mature dilution cake fertilizer water to avoid single application of nitrogen fertilizer and stop fertilization in winter.

6. Diseases and insect pests: there are not many diseases and insect pests in Rainbow Taro, which mainly include shell insects, whitefly, etc., which can be sprayed with 1000 times of 25% imidophos emulsion or 40% omethoate 1500 times. The common diseases are leaf spot and rust, which can be sprayed with 200x Bordeaux solution or 1000 times carbendazim solution for 3 times.

7. Overwintering: in addition to paying attention to heat preservation, watering should be strictly controlled when the cold winter comes. When the basin soil is too wet, it is easy to cause root rot, and the basin soil is slightly dry even if the leaves wither. When the spring warms up, new leaves will be issued again, and when the new leaves begin to germinate, they can not be watered too much, only with the increase of new leaves, the amount of water will gradually increase.
