用硫酸过氧化氢和硝酸高氯酸分别对有机无机复混肥料进行消化处理，然后进行总钾含量的测定。 |
| 9. | The content of total nitrogen and total potassium and total phosphorus in seven study sites was ranged from 10 . 04g kg - 1 to 0 . 40 g kg - 1 . 60 . 63 g kg - 1 to 22 . 23 g kg " and 6 . 27 g kg - 1 to 0 . 66 g kg - 1 , respectively
在相同条件一f ，其分解过程中养分浓度的变化没有明显的规津性，可能的原因是，第一，王朗自然保护区内降雨量较少，年平均温度软低，凋落物分解较漫，暂时还没有显示出明显的规律性。 |
| 10. | Organic matter , total nitrogen , total phosphorus and total potassium content was higher than barren sand , increasing by 1 . 78 , 1 . 97 , 1 . 64 , 1 . 14 times , it showed salix psammophila checkerboard improved fertility condition of soil
设置沙柳沙障后沙丘土壤有机质含量是对照地的1 . 78倍，全氮含量是对照地的1 . 97倍，全磷含量是对照地的1 . 64倍，全钾含量是对照地的1 . 14倍，说明设置沙柳沙障能够改善沙丘土壤的养分状况。 |
