不同林药复合经营模式对锥栗林下物种多样性的影响
|
摘要
为研究不同整地强度、不同覆盖物、不同药材对2003年建立的锥栗Castaneahenryi林下物种多样性的影响,于2016年6月采用3因素3水平田间正交试验和对角线调查方法,调查统计分析林下物种多样性,并根据Shannon-Wiener物种多样性指数、Margalef物种丰富度指数、Pielou物种均匀度指数、物种重要值4个指标对处理的物种多样性综合指数进行分析和评价。结果表明,影响物种多样性综合指数的次序为:套种作物>覆盖物>整地强度。整地强度60%、覆盖竹屑2 cm厚、套种多花黄精Polygonatum cyrtonema模式,多花黄精生长良好,多样性综合物种指数最高,套种一年林下物种数平均达12种,是不整地、不套种、不覆盖处理平均物种数的4倍。
Experiments were implemented with different interplantation of different Chinese herbals, different soil preparation intension and different coverage for studying their effect on species diversity in the Castanea henryi stands planted in 2003. Investigation on species under C. henryi with different treatments was carried out in June of 2016. Comprehensive evaluation on species diversity was analyzed by Shannon-Wiener diversity index, Margalef richness index, Pielou evenness index and important value index. The results showed that the treatment of interplanting P. cyrtonema with 60% of soil preparation and covered with bamboo saw dust had the highest comprehensive species index. The order of factors influencing species diversity index was interplantation > coverage > soil preparation intension. The experiments showed that the optimal treatment was interplanting P. cyrtonema with soil preparation intension of 60%, covered with 2 cm bamboo saw dust. It had 12 different species of plant under C. henryi.
