不同整地方式对油茶生长的影响

Effects of Different Site Preparing Modes on the Growth of Camellia oleifera Abel

2010年在德化县山区开展挖掘机水平梯田整地、带状锄草整地和全面劈草整地3种整地方式对油茶造林成活率、生长量、管理成本影响的比较研究。结果表明:不同整地方式造林,成活率和保存率高低均表现为全面劈草整地>带状锄草整地>挖掘机水平梯田整地;挖掘机水平梯田整地造林可显著促进造林当年油茶的生长,对3年生油茶的生长有极显著的促进作用;挖掘机水平梯田整地造林成本虽会有所增加,与全面劈草整地造林相比,造林成本提高14.5%,但与油茶产量关系最为密切的冠幅则增加71.8%。认为在交通方便、造林地坡度较小的情况下挖掘机水平梯田整地是一种可行的,效果较好的造林整地方式,可以进行推广。

Through the analysis of the effect of using excavators level of terraced land preparation ,ribbon and overall weeding prepa-ration and site preparing modes in the mountainous area ,Dehua in 2010 on the Camellia oleifera survival rate,growth,and manage-ment,the results showed that different soil preparation for afforestation ,the survival rate and survival rate showed as follows:overall weeding preparation and site preparing >banded weeding and soil preparation >excavator level terrace soil preparation;excavator level terraced soil preparation could significantly promote the afforestation annual growth ,which had a very significant role in promo-ting for 3-year-old Camellia oleifera survival;excavator level terrace soil preparation afforestation cost would be increased ,compared with the overall weeding preparation and site preparing , reforestation cost increased by 14.5%, but the crown width increased by 71.8%,which had the closest relation with Camellia oleifera output.On the conditions of convenient transportation ,and small plant-ing area slope degree , the excavator level terrace soil preparation was a feasible afforestation site preparation method with better effect,which could be promoted.
