【摘要】 在安徽霍山县开展了林地垦复和砍灌措施对毛竹林生长和竹林结构影响的试验研究。连续3年监测结果表明:垦复处理的林分平均胸径、1~2年生竹胸径、1~2年生竹比例、立竹度等指标分别为9.88 cm、9.96 cm、44.30%、2 918株/hm~2,分别比对照提高3.67%、5.29%、8.45%、450株/hm~2;砍灌处理的林分平均胸径、1~2年生竹胸径、1~2年生竹比例、立竹度等指标分别为9.82 cm、10.67 cm、27.26%、3 293株/hm~2,分别比对照提高3.81%、6.17%、23.29%、475株/hm~2。研究表明,抚育措施可促进毛竹林生长,优化竹林结构。更多还原

【Abstract】 The effects of reclamation and shrub cutting on the growth and structure of Phyllostachys pubescens were experimented and tested in Huoshan County,Anhui Province. The 3-year-long monitoring results showed that the average DBH,DBH of 1-and 2-year-old bamboo,the ratio of 1-and 2-year-old bamboo,and the bamboo density in the reclaimed stand of Ph. pubescens were 9. 88 cm,9. 96 cm,44. 30% and 2 918/ha,respectively,which increased by3. 67%,5. 29%,8. 45% and 450/ha compared with the control; the same indexes as above in the shrub cutting stand of Ph. pubescens were 9. 82 cm,10. 67 cm,27. 26% and 3 293/ha,respectively,which increased by 3. 81%,6. 17%,23. 29% and 475/ha compared with the control. The cultivation measures could facilitate the growth and the structure adjustment of Ph. pubescens stand.更多还原
