| 摘 要： | 采用常规方法测定了渭北黄土坮塬区110个苹果园的土壤养分含量,结果表明苹果园0～30 cm土层土壤有机质含量8.9～12.1 mg·kg-1,平均为10.05 mg·kg-1,属较低水平；有效氮、磷、钾供应状况大约为钾＞氮＞磷,按照农田土壤养分丰缺指标衡量,果园土壤普遍缺磷,约40％土壤缺氮,而钾素含量较为丰富；有效铁、锌、锰含量大部分在边缘值以下,其比例分别为铁64.5％、锌83.4％、锰91.3％,缺乏程度依次为Mn＞Zn＞Fe,远远不能满足苹果优质、高产之需要.

| Abstract: | 110 apple orchards were sampled to test the soil nutrients in the loess tableland of Weibei ar- id plateau. The result showed that organic matters in 0--30 cm layer of soil range from 8.9 to 12. ling kg-1 , with an average of 10.05mg kg-1 ;effective N,P and K are in the order of content K〉N〉 P, indicating overall lack of P according to the criteria for production and 40% of soil in short of N. |
