马尾松与黄花倒水莲复合经营技术研究

Study on the Compound Management Technology of Pinus massoniana and Polygala fallax

研究在现有马尾松林中采取间伐方式释放空间,在林内套种黄花倒水莲经营技术。试验结果表明,培育马尾松大径材的同时,兼营黄花倒水莲的主要技术是保留上层马尾松450~750株/hm^2,选择较高立地等级的林地,采取块状整地,适当使用基肥,加强抚育管理,可以提高黄花倒水莲生长量,而且马尾松单株增长量明显提高,生长环境适宜培育大径材。

This paper reported the management technology of interplanting Polygala fallax with thinning to release space in existing Pinus massoniana forests.The test results showed that,while cultivating large-diameter timber of P.massoniana,the main technique of concurrently operating P.fallax was to retain 450~750 plants/hm^2 upper P.massoniana,select higher site forest land,adopt block preparation,and use appropriate base fertilizers,strengthen parenting management.In this way,the growth of P.fallax and P.massoniana per plant increased significantly,and the growth environment adopted to cultivate large-diameter timber of P.massoniana.
