| 摘 要： | 樟子松造林后第4年进行摘芽试验,结果表明,摘芽与不摘芽的高生长和胸径生长存在明显差异,摘芽处理的高生长较不摘芽处理高出13.9%,胸径生长高出9.49%;摘芽处理树干无节高度平均为5.0 m,无节处直径与根径相差2.7 cm,而未摘芽的直径与根径相差5.4 cm,树干圆满度显著提高,经济效益明显。

| Abstract: | The bud picking and pruning test of Pinus sylvestnis var.mongolia Litv.had been conducted,and it turned out that,high growth and DBH growth of the Pinus sylvestnis var.mongolia Litv.planted forest had obvious differences between bud picking or not,the high growth of bud picking forest were 13.9% higher than that without bud picking,and the DBH growth was more than 9.49%;the average height of bud picking trunk without knot was 5.0 m,the differences between diameter and root diameter was 2.7 cm at the places without knot.Among the forest without bud picking,the differences between diameter and root diameter was 5.4 cm,stem fullness striking improved,and the economic benefit was obvious. |
