安宁八街薪炭林树种营造技术的定量选择研究

STUDIES ON THE OUANTITATIVE SELECTION OF FUELWOOD SPECIES AND PLANTING METHODS IN BAJIE,ANNING COUNTY

１９９２年７月按裂区试验要求和修改后的造林设计布置了整地方式与树种选择、密度与树种选择两个田间试验，主要供试树种为：圣诞树（ＡｃａｃｉａｄｅａｌｂａｔａＬｉｎｋ），黑荆（ＡｃａｃｉａｍｅａｒｎｓｉｉＷｉｌｌｄ．），直干桉（ＥｕｃａｌｙｐｔｕｓｍａｉｄｅｎｉＦ，Ｖ，Ｍ，），蓝桉（ＥｕｃａｌｙｐｔｕｓｇｌｏｂｔｉｌｕｓＬａｂｉｌｌ．），洋槐（ＲｏｂｉｎｉａｐｓｅｕｄｏａｃａｃｉａＬ，），山樱桃（Ｃｅｒａｓｕｓｃｏｎｒａｄｉｎａｅ（Ｋｏｃｈｎｅ）ＹｕｅｔＬｉ），桤木（ＡｌｎｕｓｃｒｅｎａｓｔｏｇｙｎｅＢｕｒｋ．），藏柏（ＣｕｐｒｅｓｓｕｓｔｏｒｕｌｏｓａＤ。Ｄｏｎ），麻栎（ＱｕｅｒｃｕｓａｃｕｔｉｓｓｉｍａＣａｒｒｕｔｈ．），毛叶山合欢（Ａｌｂｉｚｉａｍｏｌｌｉｓ（Ｗａｌｌ．）Ｂｏｉｖ．）等１０种，加上其它供试的树种共计２５种。经选择，圣诞树、黑荆、桤木、直干桉、蓝桉为入选树种，用入选树种结合选择出来的造林技术，最后找出入选树种的最佳造林技术。通过对１０个供试树种的检验，并用这种方法和标准核对了在八街等地相似立地条件下生长的相应树种，符合实际，可操作。

According to the land conditions,references,planting experience and so-cial conditions of Bajie,the silvicultural design including two split-plot designs for sitepreparation and species selection,and for planting density and species selection was fin-ished in July，1992.During the trial,25 species were tested and 10 species became ma-jor selected ones which included Acacia dealbata Link．The statistic analysis on treeheight, diameter breast-height and crown width etc.shows complex quantitative se-lecting target and planting method.Acacia dealbala Link.Acacia mearnsii Willd.Alnuscrenastogyne Bur.Eucalyptus maideni F.V.M.and Eucalyptus giobulus Labill.havebeen chosen for suitable fuelwood species,and the suitable planting method for each spe-cies has also been set according to the target by referring yearly yield of9000 kg ／ hm2 that is the target of Ministry of Forestry.The results ot the trial alsoshow that the target and planting methods have fitted the cases of land condition ofBajie.
