| Abstract: | DBH,tree height,volume growth of Populus×euramiricana ’Neva’ were analyzed.Result shows that afforestation of Populus×euramiricana ’Neva’ with grafting method for afforestation compared with the conventional method for afforestation,growth has obvious advantages;grafting method for afforestation compared to the conventional method for afforestation,the mean DBH differences for 3,7&11-year-old Populus×euramiricana ’Neva’are 6.2,11.2,8.7 cm,the differences being above 50%;the mean tree height differences are 6,10,6.3 m;differences in rates of mean tree height are above 100% in the 3rd & the 7th year;differences in rates of volume are more than 100% in the 7th & the 11th year,and the differences are significant. |
