不同坡向对旱冬瓜和西南桦造林影响的研究

Effect of Different Slope Directions on Aluns nepalensis and Betula alnoides Afforestation

  • 摘要: 以"云旱1号"、"云旱2号"和"普桦1号"为种子来源,在德宏州盈江县芒璋乡开展旱冬瓜、西南桦苗木培育及营造27 hm2技术推广示范林。在造林试验地内,同一海拔的不同坡向设置调查样地,重复3次,进行不同坡向对"云旱1号"、"云旱2号"和"普桦1号"生长的影响试验。造林1 a后,测量树高和地径,并采用多重比较法。结果显示,坡向对各个树种的树高和地径均有显著影响。在苗木生长初期,阴坡的生长状况优于阳坡。

     

    Abstract: Researches on developing seedling raising cultivation of Alnus nepalensis and Betula alnoides and establishing of 27 hm2 hectares of demonstration forest were conducted by using "Aluns nepalensis of Yunnan No. 1", "Aluns nepalensis of Yunnan No. 2" and "Betula alnoides of Pu,er No 1" as the seed source in Mangzhang township of Yingjiang County of Dehong Prefecture. In planting experiment fields, sample plots were set on the different slopes at the same elevation and the work was repeated 3 times,and researches were conducted on the effect of the different slope directions on the growth of "Aluns nepalensis of Yunnan No. 1", "Aluns nepalensis of Yunnan No. 2" and "Betula alnoides of Pu,er No 1". The tree height and diameter were measured after one year of afforestation,and the multiple comparison method was used. The results showed that the slope direction had a significant effect on the tree height and diameter of each species. In the seedling growth period,the growth on the shady slope was better than that on the sunny slope.
