采用立体经营模式对现有油茶林进行改造,能够改善油茶林地的土壤水分状况和温度状况,起保水稳温作用,减轻油茶林的冻害与旱害;同时能够改善油茶林地土壤的养分状况,研究结果表明,采用二层结构模式和三层结构模式可使土壤有机质含量的平均值分别提高0.55%和1.57%,全氮、全磷、碱解氮、速效磷含量也有不同程度提高。此外,采用立体经营模式改造油茶林能够明显提高油茶产量,并可收获大量林下植物产品,取得较大的经济效益。本文研究结果,对于合理开发利用本省乃致长江以南各省油茶林资源具有重大意义。
Stereoscopic management model of the existing transformation of Camellia oleifera forest can improve the status of Camellia oleifera forest soil moisture and temperature conditions, play a role in water and temperature stability, to reduce the freezing injury and drought of Camellia oleifera forest; at the same time can improve the status of Camellia oleifera forest soil nutrients, research The results showed that the average content of organic matter in soil increased by 0.55% and 1.57%, respectively. The content of total nitrogen, total phosphorus, available nitrogen and available phosphorus also increased to some extent by adopting two-layer structure model and three-layer structure model. In addition, the use of three-dimensional management model to transform Camellia oleifera can significantly improve the yield of Camellia, and can harvest a large number of undergrowth products, and achieved greater economic benefits. The results of this study are of great significance for the rational exploitation and utilization of the province’s Camellia forests resources to the provinces south of the Yangtze River.
