查询词典 Juglans

The results indicated that the growth of 3-year-old Prunus salicina was significantly higher than that of the other species, such as 139.1% and 153.7% higher than Toona sinensis and Juglans regia in height growth, respectively. The maximum percentage of DBH more than 1.0 cm was 91.9% for P. salicina. Next were 49.5% and 48.8% for Ulmus pumila and Pteroceltis tatarinowii, respectively. The contents of total N, total P and total K ranged from 1.36% to 2.52% in the leaves of testing species. The highest content of total N and total P was found in the leaves of Catalpa bungei, while the highest content of total K was observed in P. saltcina leaves. The results indicated that P. salicina, P. tatarinowii, U. pumila had well adaptability on the Karst area both in the growth status and the improvement to the soil with the fallen leaf.

结果表明：(1)3年生冰脆李的生长量明显优于其他树种，其高生长比香椿、核桃分别大139.1%和153.7%；植株胸径大于等于1.0 cm株数的百分比以冰脆李最高达到91.9%，其次是榆树和青檀，分别是49.5%和48.8%；(2)8个树种落叶的全N、全P和全K的总含量变动为1.36%~2.52%，其中全N、全P含量以滇楸最高，全K含量以冰脆李最大；(3)从各树种落叶前后各元素含量及其转移情况看，冰脆李、青檀表现出对大部分营养元素具有较高的循环利用养分或保持养分的能力，而香椿及刺槐相对较弱。
