| 中文摘要: |
| 在陕北黄土丘陵沟壑区,对仁用杏园的土壤有机质、全氮、全磷、速效氮、速效磷、速效钾进行了测定。0~500 cm土层的土壤有机质为3.368 g/kg,全氮为0.268 g/kg,全磷为0.536 g/kg,速效氮为13.644 m g/kg,速效磷为2.202 m g/kg,速效钾为50.406 m g/kg。陕北黄土丘陵沟壑区仁用杏园无论是浅层、根系集中分布层还是深层土壤,土壤养分含量均较低,满足不了仁用杏的正常生长与开花结实。 |

| In the loess hilly and gully region of Northern Shaanxi,the soil nutrients in almond-apricot orchards had been measured.The results showed that the organic matter,total nitrogen,total phosphorus,rapidly-available nitrogen,rapidly-available phosphors and rapidly-available potassium in 0~500 cm depth were 3.368 g/kg,0.268 g/kg,0.536 g/kg,13.644 mg/kg,2.202 mg/kg and 50.406 mg/kg respectively.The soil nutrients in different soil profiles were generally too low to satisfy the vigorous growth and fruiting of almond-apricot. |
