Through the analysis of the effect of Casuarina equisetifolia protection forest regeneratd by Acacia tree species on chemical properties of soil,the results showed that compared with stand of Casuarina equisetifolia the water-soluble Cl~-and Na~+ in sandy land were reduced by using Acacia tree species,the content of the water-soluble Ca~(2+)in topsoil was increased.
通过对相思树种更新木麻黄防护林对沿海沙地土壤化学性质的分析,结果表明:与木麻黄林分相比,在沿海沙地后沿应用相思树种造林使沙地土壤中水溶性C l-和Na+含量降低,而使表层土壤中的水溶性Ca2+含量升高;相思树种能明显地改善沙地土壤中有效养分的供给,然而,对不同的相思树种来说,其改善程度有所差异;相思树种明显地增加了沿海沙地土壤中全氮和全碳的含量,且增加的量以沙地土壤的表层最为显著。

补充资料:相思极(一作长相思)
【诗文】:
妾颜与日空,君心与日新。三年得一书,犹在湘之滨。
料君相轻意,知妾无至亲。况当受明礼,不令再嫁人。
愿君从此日,化质为妾身。
