摘  要：
对四川省凉山州盐源县代表34个乡镇7 829.84 hm2耕地和林地的310个土壤样品进行分析,研究其土壤有效硼、钼的含量及其影响因素。结果表明,有效硼、钼含量均为偏态分布,其平均含量分别为0.3196 mg·kg-1、0.1896 mg·kg-1,有效硼含量较低,作物存在潜在性缺硼。有效钼含量中等,平均含量能满足作物正常生长需要。有效硼、钼含量受土壤母质、种植作物和土壤类型影响,分析过程中发现该地区有一定的微肥施用,但是有效硼仍相对较缺乏,在生产过程中应注意补施硼肥。

摘  要：
In this article,analysis was made of soil samples collected from 7 829. 84 hectares of arable land and forest land representing 34 towns of Yanyuan County,Xichang City,Sichuan Province,and research was made on the content of available boron and molybdenum and their influence factors. The results indicated that the available molybdenum contents displayed a skewed distribution. The average contents of boron and molybdenum were 0. 3196 mg·kg- 1and 0. 1896 mg·kg- 1,respectively. The available boron content was lower,and thus the crops were potential boron deficiency. The average molybdenum content was moderate,able to meet the needs of crop growing. The contents of available boron and molybdenum were affected by soil parent material,the cropping system and soil types. In the analysis process,it was found that this area was still relatively lacking in available boron though a certain amount of microelement fertilizers had been used. So the supplement of boron fertilizer was necessary during the production.
