A rooting method for tissue-cultured shoots of cinnamomum camphora (L.) presl is disclosed. The method includes selecting cinnamomum camphora (L.) presl subcultured shoots after 35-40 d strong-shoot culture in conventional tissue culture, cutting single shoots robust in growth and having height not less than 2 cm from the subcultured shoots, inserting into an ascorbic acid sterile solution, soaking for pretreatment, vertically inserting the pretreated single shoots into a rooting culture medium, performing rooting culture in a specific light-temperature environment, conveying to a seedling growing house under natural environment conditions, and performing seedling hardening to obtain seedlings of the cinnamomum camphora (L.) presl. Through pretreating the subcultured shoots, the sassafras oil content in a notch is reduced, the rooting period is shortened, the rooting percentage is high, quality is good, and the survival rate of transplanting of the tissue-cultured rooted seedlings is high. Industrialized tissue-cultured seedling breeding can be achieved. High-quality seedlings can be provided for construction of a natural perfume artificial clonal plantation. The method has good economic benefit, ecological benefit and social benefit.

The invention discloses an introduction and cultivation technique of pigment marigold in a high altitude area, in particular an introduction and cultivation technique for an area at an altitude between 1,700 and 2,200 meters. The method comprises the steps of pretreatment of seeds of pigment marigold, seedling raising, transplanting, management and harvesting. The method adopts physical and chemical method to pretreat the seeds to achieve a germination percentage of the seeds of 90 percent and a uniform seedling raising means to provide high quality seedlings for large scale planting. By planting pigment marigold in a high altitude area, the yield of fresh flowers and content of xanthophylls in the fresh flower are greatly improved. The cultivation method, compared with the prior method, contributes to construction of standard pigment marigold plantations, carrying out standard planting demonstration of pigment marigold and improving the technological content of the pigment marigold, enables farmers to learn planting technologies of pigment marigold as quickly as possible and obtain high quality pigment marigold products, and greatly improves economic benefits.

The invention discloses a group of rapid marsdenia tenacissima propagation culture media. The main formula of the group of culture media is as follows: an induction medium of MS+6-BA 2.0mg / L+NAA 0.5mg / L; an enrichment medium of MS+6-BA 1.0mg / L+NAA 0.3mg / L; a sound seedling culture medium of MS+6-BA 1.0mg / L+NAA 0.3mg / L+NH4NO3 0.66g / L+NaH2PO4 0.56g / L+K2SO4 1.78g / L+banana 100g / L; and a rooting medium of 1 / 2MS+6-BA 0.5mg / L+IAA 0.2mg / L. The induction rate is over 88 percent, the proliferation rate is high, the rooting rate is over 95 percent, the tissue culture propagation period is short and is only 64-72 days, and effective and rapid vegetative propagation of the marsdenia tenacissima is realized.

The invention discloses an imitative-ecological podophyllum hexandrum seedling raising method, belongs to the field of ecological planting of medicinal plants and aims at solving the problems of low seedling raising rate, slow seedling growth, long seedling raising period, high cost and incidence rate increase of root rot, damping off and other diseases at a seedling stage of an existing method. The method comprises the steps of seed harvesting and storage, seed germination accelerating, sowing in a greenhouse holed tray, young seedling growth promotion and prevention and control of the diseases at the seedling stage, early sowing, planting and transplantation of podophyllum hexandrum holed-tray seedlings and culture and harvesting of high-quality podophyllum hexandrum seedlings. By adopting the imitative-ecological podophyllum hexandrum seedling raising method, the most suitable environment and nutrition conditions are created at different growth and development stages, the physiological conditions of the seedlings are improved, the seedling raising rate of the method is improved, seedling raising time is shortened, high-quality strong seedlings are cultured, further the reviving rate in a next year is improved, growth and development of the seedlings are promoted, the incidence rate is reduced, the cost is reduced, and the productivity is improved through intensive measures to achieve the best seedling raising effect.

A pteris wallichiana tissue culture rapid breeding method comprises the following steps: (1) taking pteris wallichiana mature spores as explants for disinfection; (2) putting the disinfected explants into a MS basic culture medium for inducing prothallium; (3) putting the prothallium into the MS basic culture medium for strong seedling culture to obtain sporozoites differentiated into plantlets; (4) putting the sporozoites differentiated into plantlets in a 1 / 2MS rooting culture medium for culture to obtain complete rooted seedlings; and (5) taking the complete rooted seedlings for hardening and then transplanting to a nursery greenhouse. Plants obtained by the method are strong and thick and high in survival rate, a lot of high-quality pteris wallichiana seedlings suitable for cultivation are provided, and the pteris wallichiana scale breeding problem can be effectively solved.
