How to cultivate the latest Bletilla striata seedlings?
Bletilla splendens is the tuber of Bletilla striata, a perennial herbaceous bulbous plant of the genus Bletilla in Orchidaceae, which has extensive medicinal and garden value. it is mainly used to stop bleeding, reduce swelling and produce muscle. ornamental can be potted indoor or decorated in a more shady flower bed, flower border or courtyard, let's take a look at how to cultivate Bletilla striata seedlings!
How to cultivate Bletilla striata seedlings?
1. Ramet: Bletilla striata is commonly used for ramet propagation. Before the new leaves germinate in spring or after the shoot withered in autumn and winter, the old plants are dug up and divided into pseudobulbs. Each plant can be divided into 3-5 plants, but the propagation cycle is long, the efficiency is low and the seed consumption is high. It is difficult to meet the needs of mass cultivation.
2. Sowing: Bletilla striata can be propagated by sowing, but the seeds of Bletilla striata are very small and only a few cells constitute an underdeveloped embryo, so it is difficult to germinate and grow under natural conditions, and the cultivation of seedlings is more difficult.
3. Tissue culture: the tissue culture technology of Bletilla striata can rapidly propagate a large number of seedlings, usually aseptic sowing on the culture medium, and clone propagation by tissue culture after seed germination, so as to realize the large-scale production of Bletilla striata seedlings.
How to choose Bletilla striata seedlings?
1. Variety identification: there are many varieties of Bletilla striata, but only five or six of these varieties are up to the standard, and only three are capable of high yield. if you do not have the ability to identify, you can only listen to the words of the seedling provider. it is entirely possible to buy inferior varieties.
2. Seed and seedling selection: the most common seedling cultivation methods of Bletilla striata are seed direct seeding, tuber propagation and tissue culture seedlings, of which the most reasonable and economical is seed direct seeding, which has high survival rate and high yield, but the cost is too high. the tissue culture seedling has the lowest survival rate.
3. Anti-hormone seedlings: there will be a difference of 1 to 3 months before and after the emergence time of Bletilla striata, but there is no lack of enterprises abusing hormones and chemical fertilizers to advance the emergence time by more than 5 months, and the seedlings that have been used growth hormone look very healthy. but it is easy to yellowing and withering after transplanting.
4. Ordering time: in theory, Bletilla striata can be planted all the year round, but the most suitable season is spring and autumn. Spring is the most suitable for domesticated seedlings, and early autumn is also suitable for domesticated seedlings. Truffles are generally purchased in late autumn and winter. Planting is generally not recommended in summer.
What are the risks of planting Bletilla striata?
1. Market risk: in addition to the traditional Yunguichuan, Bletilla striata production has been artificially planted in Shaanxi and Henan in the north, Fujian and Guangxi in the south, Jiangsu and Zhejiang in the east, and Gansu in the west. Therefore, overheating production is bound to form a certain risk to Bletilla striata cultivation.
2. Investment risk: compared with other planting projects, the investment cost of Bletilla striata planting is much higher, and the growth period is 2 to 3 years, which can not be borne by ordinary farmers at all. At the same time, it also increases the investment risk.
3. Provenance risk: the provenance confusion of Bletilla striata is famous in traditional Chinese medicine. At present, purple Trigeminal Bletilla striata is in circulation in the chemical industry, while the Pharmacopoeia mainly uses Purple Trigeminal Bletilla striata. Other yellow flowers, White Bletilla striata and so on are common articles and counterfeits.
4. Technical risk: the seedlings of Bletilla striata are usually transplanted after the introduction of provenances, tissue culture, refining seedlings and roots, but because the growth of the rhizome requires a symbiotic environment and very fine transplanting and management, the seedling death rate can usually reach 50% or more.
