整地对尾巨桉人工林及林下植被生长的动态影响
Dynamic effects of site preparation on the growth of E.wrophylla× E.grandis plantation and understory vegetation
摘要
Abstract
In order to explore the most suitable site preparation modes for the growth of Eucalyptus plantation and understory vegetation,we chose E.wrophylla×E.grandis plantation in the Xipi state-owned forest farm of Hua'an County in Fujian Province that used different site preparation modes(total reclamation soil preparation,furrowing soil preparation and digging hole soil preparation)to carry out 3 years' orientation observation.The results showed that: different site preparation modes had a signifi-cant impact on the tree height,DBH and individual volume of Eucalyptus plantation.After six months of afforestation,the growth of Eucalyptus plantation in the mode of total reclamation soil preparation was obviously better than that of the other two site preparation modes,and the difference had reached a significant level.In the first year of afforestation,the growth of Eucalyptus plantation that had been fur-rowing soil preparation reached the highest level.The results were as follows: furrowing soil prepara-tion＞digging hole soil preparation＞total reclamation soil preparation.In the 1.5 to 3 years of afforest-ation,the growth advantages of the growth of Eucalyptus plantation in the digging hole soil preparation were obvious.The results were as follows: digging hole soil preparation＞furrowing soil preparation＞total reclamation soil preparation.There were differences in undergrowth vegetation of Eucalyptus plan-tations under different site preparation modes,and the digging hole soil preparation and furrowing soil preparation had great advantages in increasing the number of understory vegetation.In the 1.5 to 3 years of afforestation,the vegetation richness index was the highest under the digging hole soil prepara-tion,and that of the furrowing soil preparation comes second,with that of the total reclamation soil preparation the worst.However,community coverage,Shannon-Wiener diversity index,Simpson di-versity index and Pielou evenness index were the highest under the furrowing soil preparation,followed by digging hole soil preparation,with total reclamation soil preparation the worst.Therefore,when the growth factor is the main factor,it is better to use the digging hole soil preparation; with underforest vegetation as the main factor,it is better to use the furrowing soil preparation.关键词
