摘　　要：以青山杨(Populus pseudo-cathayana×P.deltoides)和黑青杨(P.euramericana‘N3016’×P.ussuriensis)为研究对象,开展了青杨类大径材杨树水肥调控试验。结果表明:在土地较瘠薄的龙江县错海林场,对14年生青山杨林分进行施肥效果较好;在讷河市境内新江实验林场8年生黑青杨林分进行施肥、灌水对其树高有显著影响,对胸径及材积生长量均无显著影响。对青杨类杨树的水肥调控,应多关注土壤较瘠薄的地块,并以施用磷肥为佳。In this paper, Populus pseudo-cathayana × P. deltoides and P. euramericana ‘N3016’ × P. ussuriensis were the research objects, and experiments on the water and fertilizer regulation of Populus cathayana trees species with large diameter material were carried out. The results showed as follows: effect of fertilization on the 14-year-old Populus pseudo-cathayana × P. deltoides was better in the barren Cuohai Forest Farm of Longjiang County;fertilization and irrigation had a significant effect on the height of P. euramericana ‘N3016’ × P. ussuriensis in Xinjiang Experimental Forest Farm of Nehe City, and it had no significant effect on DBH growth and volume growth. Therefore, it is better to pay more attention to poor soil and apply phosphate fertilizer.
