Study On Technique Of Broadleaved-oriented Transformation Of Coniferous Forest Of CaoE River Upstream

The study focused on the establishment technique of coniferous broad-leaved forest to different forest types. The results shows:(1)establishment technique was employed to masson pine Pinus massoniana Lamb open forest that is below 0.2 crown density with rare broad-leaved tree. There were more than 10 species of trees, Schima superba, Elaeocarpus sylvestris, Cinnamomum camphora, Ligustrum lucidum, Machilus thunbergii, Michelia foveolata, Manglietia insignis, Photinia serrulata, Magnolia gradiflora, Quercus virginiana suitable for broadleaved-oriented restructure currently; (2)The hinning and the enclosed measure to masson pine pure forest and coniferous and broad-leaved mixed forest crown density above 0.5 with the renewal layers suitable for oriented cultivation. The same technique to coniferous and broad-leaved mixed forest and Mixed Broadleaved Forest that are mainly broad-leaved tree with above 0.9 crown density. The fixed standard plot by thinning the volume of forest before 6.1482 m3 improved to the three years after thinning 7.3846 m3, increment by thinning the percentage before three years later raised to 25.7%30.97%of simvastatin, closing hillsides to facilitate afforestation technology, stand had been improved productivity and quality; (3)Cuts to fire, after splitting fondle stand measures such as fire, splitting of pinus massoniana, except for closing hillsides, facilitated afforestation construction technology. The years of closing hillsides facilitated afforestation tree layer stand growth, the average height shrub layer species, average coverage, relative abundance.;(4)Test with broad-leaved construction quality assessment system to implement area, based on calculation of forest resources, thinning enclosure construction technology measures and evaluate transformation achievements on YanXiBao, fairy up in the village, the king king up 1, three recruit and bay 1, three recruit and 2, these five pieces of standard bay to score in the comprehensive were 80-90 points between, quality rating for the better, up 2, king of wang wang up 1,2 and three Yaoao up 4 sample in 80 points were comprehensive score below, showed quality needs to improve.
