摘  要:
笔者研究了连栽对江汉平原杨树人工林林分生长量的影响,结果表明:连栽条件下,前4年对杨树生长影响并不明显,但从第5~9年,第2代林较第1代林胸径减少0.70%~12.05%,树高减少7.28%~20.41%,材积减少17.78%~27.83%,单株生物量减少7.26%~32.42%;但通过施肥、间作等合理的抚育措施可以有效减小连栽对林分生长量的负面影响。

摘  要:
The effects of continuously plantation on stand growth of Populus L.plantations were studied by authors in Jianghan Plain.The results showed that compared with the first generation forests,the influence of continuously plantation on poplar growth was not significant in the previous four years,the DBH,height,volume and individual biomass decreased by 0.70%~12.05%,7.28%~20.41%,17.78%~27.83% and 7.26%~32.42% respectively in second generation forests from the fifth to the ninth year.The negative influence of continuously plantation on stand growth will be reduced obviously by fertilizing,intercropping and others reasonable tending measures.
