Research On The Qilian Juniper Nursery Afforestation Technology

Qilian Juniper (Sabina przewaIskii Kom) is one of the good native trees for afforestation in the dry land of Qinghai, for a long time because of low seed germination rate, long breeding cycle, seriously restricting seedling production and reforestation. Qilian Juniper breeding technology to promote reforestation projects on the basis of research conducted by Qinghai Forestry Institute which will be closely integrated with production forestry, mother tree nursery, the establishment of colonization breeding nursery, containers cutting, and create a model-promotion, will be assembled a number of technical support, testing and demonstration push wide application of the original results of further upgrading and improvement of the Qilian juniper tree-cutting scissors and pharmaceutical processing technology, production control technology external conditions, promote root-conversion technology and the ratio of matrix containers in key technology to improve and mature. A particular application is to sum up the net bag light matrix composite matrix for the spring and summer and winter quarters containers cutting, cutting the vessel into the outcome of the possible.The results of expert opinion: (1) Project targeted to different containers and matrix, different cutting season asexual comparative test. Summing up the following conclusions: Matrix net bag and light peat+ Perlite+Sheep Dung (6:3:1) matrix formula of combining the best nursery; temperature control in the wet equipment shed and greenhouse conditions, the spring and summer to winter quarters are cutting propagation, rooting of cuttings in summer maximum; cutting Trees used the best age for 7-8 years. (2) For the first time in a large area of containers cuttings reforestation test, summed up the different site conditions, different soil preparation, planting density of different models and technology to promote reforestation. Among them, Matrix Net Bag Light reforestation seedling survival rate was over 88%.(3) project will be effective in scientific research and production reality, the assembly adopted a number of technical support and application so that the original results of further upgrading and improvement. Qilian Juniper for future large-scale afforestation asexual reproduction and provide easy-to-use technical basis. The overall project on the domestic level to advanced.Through the project construction, infrastructure has been a greater change, production equipment usages greatly enhanced the production process light, temperature, humidity and other indicators of effective control and resolve the massive cultivation conditions, and technical indicators not control, seedling survival rate instability problems. For the future of the Qilian juniper-scale afforestation and asexual provide workable technical basis.The project implementation, production and management techniques to become more perfect technical indicators more clearly and effectively to promote the research and production of convergence to accelerate the transformation of scientific research, more systematic study summarized Qilian juniper cutting breeding and afforestation technology system, cutting through breeding, than conventional planting shortening the breeding cycle two to three years breeding, economic efficiency significantly.The implementations of projects to improve regional water conservation and soil conservation capacity have important practical significance. The technological achievements of the application area. The technological achievements of large scale applications, reduce breeding cycle and improve sustainable development of forestry, increase in forestry science and technology is of great realistic significance.
