- Abstract:
- The study was performed on the nutrients absorption and cumulation in eight types of edificatos of Seashell Islands in the Yellow River Delta. The results showed that the cumulation sequence of nitrogen in eight types of edificatos is Astragalus adsurgens>Messerschmidia sibirica>Periploca sepium>Tamarix chinensis>Setaria viridis>Limonium bicolor>Artemisia mongolica>Phragmites communis, the sequence of phosphorus in eight types of edificatos is Periploca sepium>Setaria viridis>Limonium bicolor>Messerschmidia sibirica>Artemisia mongolica>Astragalus adsurgens>Tamarix chinensis>Phragmites communis>Limonium bicolor and the sequence of potass in eight types of edificatos is Messerschmidia sibirica>Setaria viridis>Periploca sepium>Astragalus adsurgens>Artemisia mongolica>Limonium bicolor>Phragmites communis >Tamarix chinensis. There is difference of nutrition cumulation in different parts of eight plants and the basic rule of it is leaf>root>stem. The element whose nutrition cumulation is the largest one in the three parts is nitrogen and the smallest one is phosphorus. From contrasting the N/P and N/P ratios in leafs and in whole plants, we know that the ratios in leaf is bigger and which in whole plant is smaller, so we can draw a conclusion that the nutrient accumulation in leaf can better reflect the plant’s nutrient requirement than the whole plant.
