The invention discloses a fast asexual propagation method for maca hybrid. The method comprises the following steps: inoculating a sterilized maca hybrid explant into a callus inducing medium, generating callus, and the generated callus into a clump seedling generating and breeding medium to cultivate; when clump seedlings are generated and bred to a certain quantity, carrying out subculture multiplication in the breeding medium; when the quantity of the bred seedlings reaches the rooting requirements, transferring healthy main seedlings in the clump seedlings into a rooting medium to cultivate; and when the seedlings are healthy and the roots are thick, carrying out hardening-seedling for 3 days according to a conventional method, and transplanting into a floating plate with disinfection humus and cultivating for 60 days so as to obtain the healthy maca hybrid clonal seedlings. The production technology of the maca hybrid clonal seedlings is optimized and adjusted; after the callus and the clump seedlings are obtained, MS with high NH<4+> and B5 with low NH<4+> are adopted as basic culture mediums for alternative use in enrichment culture; the phenomena that a maca test-tube plantlet is easy to age and yellow are thoroughly solved; the asexual propagation cycle is shortened; the breeding efficiency is improved; and an effective way is provided for breeding of F1 generation of high-quality seedlings of the maca hybrid.

The invention provides a tissue cultivation method of vetiveria zizanioides transplants. The method comprises steps that: sterilizated vetiveria zizanioides explants are placed in induction and proliferation culture media; inducting and proliferation cultivating are carried out concurrently until explants are differentiated and young buds are germinated; times of subcultures are carried out untila required number of seedlings are obtained; the seedlings are transplanted into cultivation media to be cultivated until 3 to 5 roots appear; the seedlings are then transplanted into cultivation bags; routine managements of watering and fertilizing are carried out, and vetiveria zizanioides transplants can be obtained after 40 days of growth. With the method provided by the present invention, usage amounts of drugs can be reduced. Through the concurrent inducting and proliferation cultivating, appearances of variants can be efficiently controlled, tissue cultivating processes can be simplified, propagation periods can be shortened, production cost can be reduced, and merits of vetiveria zizanioides varieties can be kept fast and stably. With the method provided by the present invention, problems in methods with common propagation systems, such as complex parent resources, unstable seedling qualities and slow seedling propagations, can be solved.

A provided dendrobium aphyllum tissue-culture quick propagation method comprises: germination of cracked mature seeds obtained by inbred of dendrobium aphyllum, forming and differentiation of protocorms, rooting culture, culture of complete plants, transplanting and surviving. Compared with conventional propagation methods such as high-position bud cutting or strain segregating, the method provided by the invention employs tissue culture technology for propagation of dendrobium aphyllum, and the tissue culture of dendrobium aphyllum is performed by employing protocorms, so that the propagation speed is fast, a large number of seedlings are obtained and grow well, and thus a large number of dendrobium aphyllum seedlings with same properties are cultured in a short period, the transplanting survival rate is high, the market demand is satisfied, and the method has various advantages such as low cost, short period, high yield and the like.

The invention provides a method for polyploid induction of red fruit ginseng and an efficient artificial seedling cultivation method for polyploid plants, comprising the following steps: (1) inoculating the sterilized seeds in medium A for aseptic germination; (2) Get sterile seedlings with leafy stem tips and soak them in sterilized colchicine solution, then transfer them to medium C after cultivating them in medium B; (3) polyploid plants are grown in medium C Proliferation and rooting can be completed in one step. The invention optimizes and adjusts the process of in vitro rapid propagation of polyploid plants of red ginseng, synchronously multiplies and takes root, simplifies the tissue culture process, and carries out the whole culture process in one culture medium at the same time, greatly improving the artificial in vitro propagation efficiency. In addition, the present invention establishes a red fruit ginseng autopolyploid induction system; in the case of delayed polyploid growth, the direct organogenesis method is adopted to proliferate, while maintaining a high reproduction coefficient, greatly shortening the culture period, and reducing the cost. Low cost, short cycle time, high quality and high survival rate.

The invention provides a pararuellia delavayana reproduction method. The method comprises the steps that a disinfected and sterilized pararuellia delavayana explant is inoculated into different culture media successively for callus induction, bud production and reproduction synchronous culture. According to the pararuellia delavayana reproduction method, the common vitrification phenomenon produced during rapid asexual propagation is avoided, the cost is low, time is short, and the quality and survival rate are high.

The present invention innovatively utilizes tidal bioreactors to rapidly propagate lily transplanted seed balls, by cultivating and growing lily seed balls with a diameter of 0.2 to 0.4 cm in conventional solid propagation medium as explants and inserting them into tidal bioreactors. In the bioreactor, the liquid medium formula was replaced during the 50-day cultivation process, and the pollution was controlled by adding drugs, and the seed balls were gradually expanded and rooted. After the seed balls were released from the bottle, the lily seed balls were vernalized, transplanted, Planting methods are managed. The present invention can simplify the tissue culture procedure by gradually carrying out seed ball expansion and rooting culture, greatly reduce the labor cost in conventional solid tissue culture, and can effectively control pollution and the generation of mutant strains, shorten the lily breeding cycle, and save The cost of production can quickly fix and maintain the excellent characters of new lily varieties, and solve the problems of slow breeding speed, mixed provenance and unstable quality of seed balls produced by conventional lily breeding systems.

The invention discloses a method for artificial high-efficiency propagation of Swertia variegata. In the same medium, callus induction and basal shoot cluster formation can be carried out at the same time, and basal tube cluster bud formation and multiplication culture can be carried out simultaneously. The culture procedure is simplified to three steps; the entire rapid propagation process only needs three kinds of medium to solve the problems of callus, basal shoot clustering bud generation and proliferation, overcoming browning and vitrification, and rooting, saving inoculation procedures and The cultivation space is conducive to the arrangement of production plans; in addition, because the number of inoculations is reduced, the possibility of contamination is reduced, and the medium for callus induction and proliferation culture has the function of basal shoot clustering, which makes the biological material replace the medium It is easier to adapt, thereby improving the success rate of tissue culture of biological materials, and greatly improving the reproduction coefficient.
