摘要:
为了解余姚市杭州湾沿岸基干林带建设情况,于2018 年10-11 月对各基干林带的生长状况和土壤改良情况进行调查和研究。结果表明,基干林带整体造林保存率达85%,林分平均郁闭度 > 0.65,造林总体质量良好。2010 年造林林带的平均蓄积量和平均生物量最高,2010 年和2013 年造林林带生长最快,其中以35 杨Populus sp.,竹柳Salix fragilis,水杉Metasequoia glyptostroboides 的生长最快。竹柳,木麻黄Casuarina equisetifolia 以及部分臭椿Ailanthus altissima 和35 杨长势较差,其他树种长势良好。造林可提高土壤总氮和有机质含量,并可有效降低含盐量。不同造林树种均可有效提高根际土壤总氮和有机质含量,并可显著降低土壤含盐量;乌桕Sapiumsebiferum 可有效提高根际土壤总磷水平。综上分析,35 杨,乌桕,黄连木Pistacia chinensis,夹竹桃Nerium indicum等可作为余姚市杭州湾沿岸基干林带的适宜树种优先选用。
Abstract:
Investigations were carried out in October and November of 2018 on growth and soil improvement in coastal backbone shelterbelt constructed from 2007 to 2015 in Yuyao city, Zhejiang province.The results showed that conservation rate of surveyed forest was up to 85%, and the average canopy density was over 0.65.The mean stand volume and biomass of the shelterbelt built in 2010 were the highest, and that in 2010 and 2013 had the fastest growth.Among planted tree species, Populus sp., Salix fragilis and Metasequoia glyptostroboides had the fastest growth, but Casuarina equisetifolia and Ailanthus altissima slower.The investigation indicated that afforestation could increase the content of soil total nitrogen and organic matter, and could effectively reduce salt content.Each tree species could effectively increase the content of total nitrogen and organic matter in rhizosphere soil, and significantly reduce the content of soil salt.Sapium sebiferum could effectively increase the total phosphorus content in rhizosphere soil.Comprehensive analysis demonstrated that P.sp., S.sebiferum, Pistacia chinensi and Nerium indicum could be selected for afforestation of coastal shelterbelt.
