Ramet method

Ramet is the most commonly used breeding method of double line taro, which is generally carried out when the temperature reaches about 20 ℃ in spring

The soil of flowerpot or seedbed shall be slightly acidic soil rich in humus, which is generally mixed with rotten leaf soil and peat soil; It can also be mixed with pond mud, peat and perlite in the ratio of 2:3:1; Or it is made of loose rotten leaf soil rich in organic matter, 1 / 3 perlite and a small amount of base fertilizer

First, use a sharp blade to cut the root block with stem, leaf or leaf bud. If it is family breeding and the quantity demand is small, you can directly place the cut root block with stem, leaf and leaf bud directly in the flower pot; If it is mass breeding, it should be placed in the seedbed

To keep the ambient temperature at 20 ℃ - 28 ℃ and the relative humidity above 80%, if the temperature and humidity cannot be reached, it is necessary to cover a layer of film on the flowerpot or seedbed

Cutting method

Cutting is generally carried out when the temperature is not lower than 20 ℃, which can be carried out in any season

The cutting of double line bamboo taro generally uses the top tender shoot, and the length of the cuttings should be 10-15 cm. If the leaves grow vigorously, one third of the leaves need to be retained. If the leaves grow weakly and small, one half of the leaves need to be retained

Before cutting, soak the cuttings in 500 ppm Nai acetic acid solution for 2-3 seconds, or treat them with indole acetic acid, indole butyric acid and ABT rooting powder

After treatment, the cuttings will be inserted obliquely into the seedbed or flowerpot. If mass reproduction is carried out, the plant row spacing of double-line bamboo taro should be less than 5 × About 10 cm, so as to ensure the normal growth of the plant

After cutting, cover with film, control the temperature at 20 ℃ - 30 ℃, and the air relative humidity at 75% - 85%

The survival rate of cutting is lower than that of plant propagation, about 50%, so it is best to adopt the mode of plant propagation in general family breeding
