河北省滨海盐碱地土壤与盐生植物养分特征的研究

Studies on the nutrient characteristics of soil and halophyte in coastal saline soil of Hebei Province

    摘要
  • 摘要: 对滨海盐碱地土壤和植物样品分析结果表明，生长不同盐生植物的土壤含盐量不同，以生长白剌(Nitraria sibirica Pa11．)的土壤含盐量最高，达18．5g／kg，盐地碱蓬(Suaeda salsa L．Pal1．)次之，柽柳的最低。盐生植物的生长改变了土壤养分特征，4种生长盐生植物的土壤养分含量均高于光板地，土壤有机质含量增加44％ 以上，生长木本盐生植物白刺、柽柳(Tamarix chinensis Lour．)的土壤养分含量高于生长草本盐生植物碱蓬、碱茅(Puccinellia distansJacq．Par1．)的土壤，且不同盐生植物养分特征不同，白剌、柽柳N和P含量均高于盐地碱蓬、碱茅，K含量则与植物耐盐特性有关。

     

    Abstract: Based on the field investigation，soil and plant samples are analyzed to study the nutrient characteristics of soil and halophyte in coastal saline soil in Hebei Province．The results show that the halophyte species is different with the difference of soil salt content．Nitraria sibirica Pal1．can grow in the more salinity saline soil．Because of the growth of halophytes ，the soil nutrient content is increased and it is higher in the soils with Nitraria sibirica Pall and Tamarix chinensis Lour．than that in the soils with Suaeda salsa (L.)Pall. and Puccinellia distans(L.)Par1．N，P contents in Nitraria sibirica Pall and Tamarix chinensis Lour．plants are higher than those in the plants of Suaeda salsa (L．)Pal1．and Puccinellia distans(L．)ParI.K content in the plants has the tendency to increase with the increase of soil salt content．
