來端 摘 要:通過不同剪頂時(shí)間和剪頂高度對(duì)火炬松、濕地松和馬尾松的萌條數(shù)量、長(zhǎng)度和徑粗的影響研究.結(jié)果表明:不同樹種由于其生物學(xué)特性不同,適宜的截頂時(shí)間、截頂高度表現(xiàn)不一致.火炬松適宜的截頂時(shí)間為8月20日至8月25日,截頂高度以15cm為最宜;馬尾松適宜的截頂時(shí)間為7月30日,截頂高度為8cm;濕地松適宜的截頂時(shí)間為8月15日至8月20日,截頂高度為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. |
