摘要
2019年在福建省建宁国有林场对香椿、多穗柯单一经营模式和香椿、多穗柯复合经营模式的8年生林分的生长效应和水源涵养能力进行测定分析。结果表明,香椿、多穗柯经合理配置和人工调节可以形成复合林分,无论是香椿,还是多穗柯生长状况良好。8年生复合林分,香椿单株材积可达0.0403 m^(3),多穗柯嫩叶、嫩枝鲜质量平均达2.54 kg·株^(-1)·a^(-1);土壤水分物理性质均比香椿、多穗柯单一经营模式得到改善;具有较高的水源涵养能力,总涵养量为296.77 t·hm^(-2)。
In 2019,the growth effect and water conservation capacity of 8-year-old stands of Toona sinensis and Lithocarpus polystachyus under single management mode and compound management mode were measured and analyzed in Jianning State-owned Forest Farm of Fujian Province.The results show that compound stand can be formed by rational allocation and artificial adjustment during tree growth process.Tree growth is robust in the compound stand for both Toona sinensis and Lithocarpus polystachyus species.In the 8-year compound stand,the individual tree volume for Toona sinensis is up to 0.0403 m^(3);the average fresh mass of leaves and shoots for Lithocarpus polystachyus is up to 2.54 kg·plant^(-1)per year;the physical properties of soil water have been improved and the total water holding capacity is 296.77 t·hm^(-2),which is significantly higher than the monoculture of Toona sinensis and Lithocarpus polystachyus.
