Propagation method of plantain
The propagation methods of plantain can be divided into cutting propagation, layering propagation and sowing propagation p>
Cutting propagation
The branching ability of plantain is relatively poor, so it is necessary to cultivate cutting mother plants. From June to October, cut the top branches of plantain, about 8 ~ 10cm long, with 5 ~ 6 leaves. After cutting them short, insert them into the sand bed and keep them moist. The appropriate temperature range is 24 ~ 27 ℃, not lower than 20 ℃. About 30 ~ 40 days after sowing, the roots will sprout and potted when the new branches grow to 4 ~ 5cm. Cuttings need to be treated with 0.2% indole butyric acid for 2 seconds, which can improve the rooting rate and shorten the rooting days p>
Strip propagation
From May to June, the method of high-altitude strip pressing is usually used for breeding. Select the strong main stem, peel it in a ring 20 cm away from the top, 1 cm wide, cover it with wet moss, and then wrap it with plastic film. The indoor temperature needs to be kept above 20 ℃, root in about 40 days, and cut the potted plant after 60 days p>
Sowing and propagation
The seeds of plantain mature in September. Its seeds are relatively large. They are generally sown in shallow pots. The appropriate temperature for seed germination is 24 ~ 27 ℃. After sowing for 2 weeks, they germinate. When the seedling height is 4 ~ 5 cm, they are transplanted in 4 cm pots< span>
