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. |
