摘要: 杨树在我国分布广范,在生态建设中发挥了重要作用,但由于自然灾害、品种退化、更新不及时等原因,造成杨树低效林在全国尤其是三北地区普遍存在。杨树伐根嫁接具有经济、节水、环保的优点,是杨树低效林更新的优选方法。分析伐根嫁接林地的生产力、经济效益、生态效益和社会效益,明确伐根嫁接更新造林优势,可带动并加快衰老低效杨树防护林更新改造速度,提高林地效益。

关键词: 杨树, 低效林, 伐根嫁接, 更新改造, 效益

Abstract: Poplar trees are widely distributed in our country. They play an important role in ecological construction,but as a result of natural disasters,variety degeneration and untimely regeneration cause inefficient poplar forest to be commonly seen across the country,especially in the three north areas.Poplar stump grafting has the advantages of economy,water saving and environmental protection,which is a preferred method for improving inefficient poplar forest. Analysis of productivity,economic benefit,ecological benefit and social benefit in stump grafting forest land and identifying of the advantages of stump grafting in reforestation can drive and speed up the upgrading aging inefficient poplar shelterbelt and improve the efficiency of the forest land.

Key words: Poplar, inefficiency forest, stump grafting, update, efficiency
