Propagation methods of Bletilla striata

Bletilla prefers warm, humid environment, such as wild valley forest, slightly cold-tolerant, open field cultivation in the middle and lower reaches of the Yangtze River, strong shade tolerance, avoid direct light, high temperature and drought in summer, leaves are easy to wither and yellow, and should be well drained from sandy loam soil with a lot of humus. Bletilla striata reproduction methods are mainly ramet reproduction and sowing reproduction, let's take a look at it!

Ramet propagation of Bletilla striata

Bletilla splendens is often propagated by ramets. Before the new leaves germinate in spring or after the shoot withered in autumn and winter, the old plants are dug up and the pseudobulbs are divided into 5 plants, each plant can be divided into 5 plants with terminal buds. Traditional cultivation mainly depends on ramet propagation.

However, due to the long propagation cycle, low reproduction efficiency and high seed consumption, it is difficult to meet the needs of mass cultivation.

Sowing and propagation of Bletilla striata

Bletilla striata can also be propagated by sowing, but the seeds of Bletilla striata are very small and without endosperm, so it is difficult to germinate and grow under natural conditions, and the cultivation of seedlings is more difficult.

Tissue culture technology can rapidly propagate a large number of seedlings, sow aseptic seeds on different media, and propagate clones by tissue culture after seed germination, so as to realize large-scale production of Bletilla striata seedlings and explore effective rapid propagation techniques.

Pest control of Bletilla striata

Black spot disease often occurs and is sprayed with 1000 times of thiophanate methyl wet powder. Sometimes root-knot nematode disease is harmful, and 3% carbofuran granules are used to irrigate the basin soil.
