Heilongjiang Province, Mainly Fast-growing Poplar Tree Growth And Stress Resistance Evaluation

Heilongjiang Province is located in the Alpine region. For its cold weather, tree growth is slow. To breeding a new fast and strong resistance varieties of poplar is important to solving the shortage of wood, poplar decline in quality, the lack of new varieties. In this paper, poplar trees in Heilongjiang Province to carry out its evaluation of growth traits and resistance-like, to acquire all varieties of poplar tree growth characteristics, physiological and biochemical characteristics and ecological features of Heilongjiang Province for the cultivation of poplar zoning and use of scientific and rational provide the basis species.Through the Rating by test, filter out all regions of Heilongjiang's fast-growing species suitable for cultivation.In Daqing in Heilongjiang Province as the center of the western region, it is laid Zhaozhou test ratings forest and forest appraisal of the fast-growing varieties of poplar growth and resistance evaluation. The results show that: the Netherlands 3930 and A5 excellent growth in the region, showing strong disease resistance, insect resistance, cold and other characteristic. It can be in the region to promote large-scale cultivation.In the central region of Heilongjiang Province in the Maoer Mountain area and Yabuli area, It is established an experimental forest to evaluate the fast-growing varieties of poplar growth and resistance evaluation. The results indicate that the species existing Poplar trees can be normal in the region growth, growth index was significantly higher than the control Populus, and no frost damage occurs, but the frequent occurrence of pests and diseases, particularly serious leaf-eating pests.In Shuangyashan in the eastern part of Heilongjiang Province, Fujin, Dongfanghong and Baoquanling region, it is established pilot rating Forest and other places of the fast-growing poplar varieties resistant to the growth and evaluation. The results show that A5, B6, black 14, A43 such as the growth of poplar trees in the eastern region, and good index of freezing injury and disease and insect pests were no significant differences and no apparent frost damage occurs. And the above Species can be selected as the fast grow species in those regions.
