Preliminary Study On Growth Adaptability And Cold Resistance Of Introduced Sichuan

Dendrocalamus tibeticus Hsuch et Yi, which belong to gramineae bambusoideae negundo bamboo genera, mainly distributed in motuo county, Tibet autonomous region in China. This is about more than 40 species, distributed in Asia, tropical and subtropical area. Negundo bamboo has widely application value, negundo bamboo pole strong, smooth texture is straight, is to create a musical instrument, cultural and sports supplies, furniture, and the important material such as arts and crafts.Dendrocalamus tibeticus Hsuch et Yi as a plant chain component of ecological environment, not only to the environment with high ecological value, at the same time, because the material is good, the biomass is big, as raw material of lumber and pulp industry, has the very high economic value. This kind of distribution found in Tibet in China, yun nan province. Therefore, si chuan is clumped bamboo distribution and industrialization in China, collect more and successfully introduced germplasm resources, and make the development of the bamboo has better market prospect. In this paper, the purpose of research is to explore whether adapt to Tibet pastoral bamboo introduction sichuan PenZhou region, and its research method is based on Tibetan pastoral bamboo oneself physiology characteristic, based on the experience of the other plants in the region for introduction, mainly through the introduction to the natural conditions and Tibetan pastoral bamboo growth characteristics, physiological and ecological adaptability and adaptability to the environment under low temperature stress of the comparison research, explore negundo bamboo grow in the introduction area in the process of temperature, soil conditions, and the influence of other factors on the pastoral bamboo growth process. Especially under the low temperature stress, the pastoral bamboo could be normal growth, and the enzyme activity in the body physiological changes such as features, and for Tibet pastoral bamboo successful introduction and increase the cluster bamboo germplasm resources in sichuan has important practical significance.Experiment is the main process of sampling from Tibet ink to take off the sample back to chengdu, in chengdu area and zigong area for planting, selection of the experimental sample Honda yibin seven field respectively. Yibin peanut slope. Chengdu shiyang three typical land, then to negundo bamboo measurement analysis of the physiological indexes in the body. In accordance with the basic principle of plant introduction, methods and procedure of investigation and analysis of the introduction to the existing negundo bamboo and its application status, and in the consult literature and introduction on the basis of feasibility analysis, and finally established in sichuan province to pastoral testing scheme of bamboo species introduction, it has obtained the following main results and innovation points:in this paper, we will bamboo introduction to sichuan and Tibet pastoral area, the end result is to explore negundo bamboo introduction success, in the process of analysis of the introduction of the success of pastoral bamboo, using the related mathematics analysis, the influence of negundo bamboo and normal growth factors and pastoral bamboo in the low temperature environment, this paper analyzes the factors which influence the growth and gives different weights to the factors that will be in accordance with the relevant determination of physiological index, scores for each factor score and the scores, the results through the total score to determine whether the Tibetan pastoral bamboo in sichuan area introduction was successful. By means of mathematical analysis, weight natively related physiological index contrast analysis methods such as analysis, determines negundo bamboo in sichuan were successful, has good biological adaptability, can be the winter in sichuan region.Get through this test, for nearly two years after the introduction of negundo bamboo related data of observation and summary, and found that after introduction of pastoral bamboo growth indicators are similar to natively negundo bamboo growth index. Has good biological adaptability. Will analyze the three areas of the testbed, and prior to introduction of the pastoral bamboo bamboo the physiological indexes of physiological indexes and the introduction of negundo after comparing analysis, discovery and not introduced negundo bamboo growth index, shows that after the introduction of pastoral bamboo in sichuan province has a good adaptability, introduced successful negundo bamboo in sichuan region...
