The invention relates to a Taxus chinensis var.mairei seedling breeding method and belongs to the technical field of plant cultivation. The method comprises the following steps: collecting seeds, removing moisture after preparation, storing the seeds in a room, carrying out land preparation, applying a base fertilizer on the ground, sowing, shading, paying attention to watering and drainage, fertilizing and managing to obtain shoots, transplanting, digging a pit in the room, and carrying out piled storage. Stratification by digging the pit in the room is less influenced by external environment, and temperature, humidity and the like can be manually controlled. Thus, environmental conditions required by seed stratification are guaranteed, and seeds can be effectively prevented from being mildewed during the storage process.

The invention relates to the technical field of plant vegetative propagation, in particular to a taxus chinensis vegetative propagation rapidly rooting method. The method comprises the steps of building a seedbed, collecting taxus chinensis detached materials, manufacturing and processing; selecting a number one ABT rooting powder as rooting agent, manufacturing solid rooting liquid by using water-retaining agent, inserting the taxus chinensis into the seedbed, distributing the solid rooting liquid on the seedbed and managing the seedbed during growing seeding. By using a function of absorbing a hundred times of water of the water-retaining agent, the used rooting liquid is diluted into the rooting liquid with a low density, and is absorbed again to form the solid rooting liquid; and the solid rooting liquid provides the detached materials with medicine liquid in a slow and uniform mode in a whole, middle and later period in a substrate,, carries out omnibearing induced root treatment so as to promote the detached materials to grow root in a short period. The water-retaining agent absorbs and stores rich water on leaf surfaces according to the function of the water-retaining agent, and provides the rich water to the detached materials in a slow and uniform mode. The detached materials can grow in a healthy and strong way and grow up to seeding as quickly as possible.

A stereo-culture method for Camptotheca acuminata, enqlish yew and rosemary features that they are planted at different densities according to their biologic and ecological characteristics to increase their yields per unit area.

The invention provides a method for breeding and cultivating taxus mairei with a seed, and the method comprises the following steps that a taxus mairei seedling is obtained by breeding and cultivating the sexual seed; the taxus mairei seedling is transplanted and planted, and a large taxus mairei seedling and a young tree are obtained; and the cultivation area of the taxus mairei is expanded. Special cultivation management measures for the taxus mairei are adopted to establish a taxus mairei breeding and cultivation technical system, a manual way to breed the taxus mairei is opened up, so that the large-scale industrial production of the taxus mairei becomes possible, the market demand for the taxus mairei is met, and a good test system is provided for protecting endangered species of wild plant resources.

The invention relates to a method for extracting essential oil of taxus media. The method comprises the following steps of: 1, preprocessing raw materials: removing impurity from tender leaves and / or branches of fresh taxus media and crushing the tender leaves and / or branches to obtain pieces or powder of the raw materials; 2, performing steam distillation: uniformly mixing the pieces or powder of the raw materials and common salt, and placing the mixture in a distiller for steam distillation; and 3, separating oil from water: performing high-speed centrifugal separation or standing separation on the collected oil-water mixture to obtain the essential oil of the taxus media. The method of the invention has the advantages of simple process, less equipment, low cost, no pollution, and special suitability for medium- and small-size enterprises.

The invention discloses a seedling culturing method for a Chinese yew. The seedling culturing method includes the steps of seed collection, seed storage, seed processing, soil preparation and seedling, seedling management, transplantation, interplanting and the like. Firstly, seed coats of seeds are thinned through a rubbing method, then the seeds are mixed with wet sand and stored in a soil pit, in the next spring, the seeds are taken out and sequentially soaked in disinfectant and plant growth regulator, then, the seeds undergo accelerating germination in a greenhouse, and the seeds can be planted when the seeds become white. Farmyard manure is added after deep ploughing and soil preparation, the seeds are planted on a seedbed, covered by thin soil, watered and receive moisturizing processing, and 50-70% of the seeds are shaded in a seedling stage. In the process of transplantation, neutral and acidulous properly-thick soil layers with the height of 1500-3500m are selected, base fertilizer is added, roots of sprouts are soaked in wet earth containing organic fertilizer, and then the sprouts are planted in a three-dimensional growth environment in an interplanting mode, wherein the tree of overstory in the three-dimensional growth environment is pinus yunnanensis, and ground flora of the three-dimensional growth environment is fern. Tests show that according to the seedling culturing method for the Chinese yew, dormancy periods of Chinese yew seeds can be shortened greatly, bud ratios and transplantation survival rates are improved, and the Chinese yew is quick in growth, early in fruiting and suitable for being popularized and planted in a large area.
