摘要
本文研究隆安县不同地层的土壤元素含量对荔枝生产的影响。通过分析地层的岩石、土壤、荔枝叶矿物元素含量及其与产量的相关性,确定隆安县荔枝适生地层。提出可能促进隆安县荔枝高产的有SiO2和Mg元素;隆安荔枝生产中,土壤的Zn、B及N、P、K均感不足;引起荔枝中毒造成地层劣势可能是因为Al、Cu、As和Mn含量过高;荔枝含硫量很低,可能为低硫植物。在上述基础上,进行隆安县荔枝生产布局和管理建议。
The different mineral contents may affect the production of Litchi.In this study the mineral element contents in rocks,soils,leaves of Litchi on strata where Litchi grows,and their relationship with yield of Litchi in Longan County.The results showed that SiO2 and Mg can increase the Litchi production,Zn and S are lacking in soil to Litchi growth,and more contents of Al,Cu,As,Mn could poison Litchi,S is so few in Litchi that it may likely be a low S-content plant. With this reasults,we propose the rationally distribution of patterns of Litchi cultivation and the way to manage Litchi production in Longan County.
