| Abstract: | This article analyses annual growth and young tree growth aboutPopulusבLinxia-85’at age of 12 years using P.cathayana Rehd as check the PopulusבLinxia-85’has some characteristics: ①Growth season put off 10～15 d. Growth period for every year prolong 20 d. ②It is sensitive to the change of outside environment. It can make full use of summer-autumn rainwater in the locality. To accelerate growth, it utilizes water, light and heat coordinatly. ③The volume growth of the young-tree improves 88.98 % than the check.The mature period of quantity is twenty-two years. ④The quick growth period is longer than the check.Middle-big diametertree and bumper crop cultivation is fit for it. |
