When spring comes, choose to dig up its old roots before the germination of new leaves or after the withering of the upper part of the ground in autumn and winter, and divide it into fake bulbs. Generally, each plant can be divided into about 4 plants, but it must take a little top bud, so that it can survive more easily.
Generally, the traditional cultivation tries to choose the way of Plant Division for propagation, but this method is too long for propagation, and the efficiency is not high, because it needs to consume more seeds, so it will be difficult to meet the needs of a large number of cultivation with this method.
Of course, Bletilla can also be propagated by sowing seeds, but the seeds of Bletilla are relatively small and have no endosperm, so it is generally not easy to germinate and grow under natural conditions, and it is difficult to grow seedlings. But our country has also carried out a series of research on this phenomenon, and then through some experimental seeding and tube seedling methods, we found that it can improve the survival rate of seeding. Then the tissue culture technology can be used for rapid propagation, aseptic propagation on different media.
When the seed germinates, it can be propagated asexually by means of tissue culture, and then this method can make the seedlings of Bletilla striata produce on a large scale, and it can also be propagated rapidly. The method of adopting this technology can survive a lot, meet the needs of production, and save a lot of time, so now the general artificial propagation If the amount of colonization is large, this method will be chosen, and the cost is not very much, and the probability of survival is also relatively large
