来端 摘 要:通过不同剪顶时间和剪顶高度对火炬松、湿地松和马尾松的萌条数量、长度和径粗的影响研究.结果表明:不同树种由于其生物学特性不同,适宜的截顶时间、截顶高度表现不一致.火炬松适宜的截顶时间为8月20日至8月25日,截顶高度以15cm为最宜;马尾松适宜的截顶时间为7月30日,截顶高度为8cm;湿地松适宜的截顶时间为8月15日至8月20日,截顶高度为15cm. Building Techniques of Cuttings Orchard of Pinus taeda,Pinus elliottii and Pinus massoniana LAI Duan(The Popularizing Centre of
Forestry Science and Technology in Shaowu City,Shaowu 354000,China) Abstract:In this paper,the effect of time and retention hei ght of topping on
quantity,length and basal diameter of coppice shoot of Pinus taeda,Pinus
elliottii and Pinus massonian a has been studied.The results showed that because
of difference of b iological properties among three tree species, suitable time
and retention heigh t of topping among three tree species are different.The
suitable topping time o f Pinus taeda is August 20 to August 25,the best
retention height of topping is 15 cm; The suitable topping time of Pinus masson
iana is July 30, the best retention height of topping is 8 cm; The su itable
topping time of Pinus elliottii is August 15 to Aug ust 20,the best retention
height of topping is 15 cm. |
