The Growth Effect Assessment Of Different Management Measures On Young Forest Growth Of Huge End Eucalyptus

Huge end eucalyptus (Eucalyptus grandis X E.urophyll) is one of the excellent fast-growing economy of the introduction of trees, with a high economic value. After the introduction, several southern provinces in the country have grown. To ensure huge end eucalyptus can play the best economic benefits, in plantation management, the need to adopt a different management methods for their growth characteristics and needs. For this reason, many scholars in all aspects huge end eucalyptus planted research and exploration. This paper attempts to carry out research from the management measures, such as in terms of ground clearance, forest land preparation methods, forest soil fertilizer and different way of tending measures, through the analysis of the effects of different management measures on huge end eucalyptus young forest produce, to find the most suitable management measures for the young plantation of the huge end eucalyptus.The author carried out the experiment in2006, to try to grow clones of the1st Mohs huge end eucalyptus in the YunXiao YuanLing Woodland. Slash by comparing experimental and not controlled burning, different planting densities, chemical weed control and manual weeding, fertilizing different ways of comparing different thinning intensities, verifying rational and efficient cultivation methods. Experimental result shows five aspects. One, slash faster than without soil, removing weeds, low cost, easy to operate. The benefits of two, initial planting density of about1650/hm2for huge end eucalyptus woodland tree height growth is more obvious. Three, chemical weed control efficacy for a long time, the effect is obvious, absorption, does not destroy the soil, but also remove some of the difficult excavation of weed. Chemical weed control also help to increase the porosity, is conducive to the development of eucalyptus roots. Four, full forest economy, with the use of organic manure and chemical fertilizers applied, can improve the fertilization effect. Five, forest thinning on tree height, diameter significantly affected first thinning intensity0.6is appropriate to retain the number of trees in the950to1250/hm2, secondary thinning to determine the actual situation. Rational forest thinning can increase wind resistance, promote tree growth, and increase economic efficiency.Huge end eucalyptus plantation as higher raw power of economic interests of people planting, in order to create the ideal excellent woodland, to obtain a higher growth, more efforts must be made to determine the actual situation and the economic capacity moderate eucalyptus tending to select varieties of quality planting seedlings become the basis and reasonable ground clearance, forest site preparation, forest fertilization. Thinning and other necessary means to become huge end eucalyptus woodland of high growth. We should also protect the environment while pursuing high economic efficiency, not to blindly pursue economic benefits to the detriment of the legitimate rights and interests of future generations in exchange. We must protect at the same time to achieve results of our living environment. Therefore, based on scientific and rational management of woodland and reasonable afforestation, so that take full advantage of the growth huge end eucalyptus law, in line with the corresponding scientific management, to make huge end eucalyptus harvest yield. Hope this research will help farmers find a suitable planting of Young huge end eucalyptus scientific approach to maximize economic benefits.
