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

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．
