对皖东丘陵地区麻栎人工林的生长特性和林分结构作了全面地调查研究,并结合群众生产经验,提出了有效的栽培模式和栽培技术,建立了较大规模的示范林。其中薪炭林经营模式,10 a生左右的林分,平均胸径达7~8 cm,平均高7 m以上,年生产薪材9000~10500 kg/hm2(鲜重),最高达15000 kg/hm2;而用材林经营模式,20~30 a即可培育成中小径阶用材,40~60 a可培育成胸径达24 cm以上的大径阶用材,年材积生长量6~9m3/hm2,最高可达12 m3/hm2,成为该地区的高产林分,能取得较好的生态、经济和社会效益,为该地区黑松等低效林改造提供了重要参考。 Based on the investigation of growth characteristics and stand structure of Quercus aculaea plantation in the hilly area of ​​eastern Anhui Province, the authors put forward effective cultivation models and cultivation techniques in combination with mass production experience and set up large-scale demonstration forests. Among them, the fuelwood forest management mode has an average diameter at breast height of 7 to 8 cm and an average height of 7 m or more, with an annual output of 9,000 to 10,500 kg / hm2 (fresh weight) and a maximum of 15,000 kg / hm2; The timber forest management model, 20 ~ 30 a can be bred into medium and small diameter timber, 40 ~ 60 a can be bred as a diameter of 24 cm above the large diameter timber, the annual volume growth of 6 ~ 9m3 / hm2, up to 12 m3 / hm2, becoming the high yielding stand in the area, which can achieve better ecological, economic and social benefits, which provides an important reference for the transformation of low effective forests such as Pinus thunbergii in the area.
