Author was menstruated content of boron and researched the status of lack of Boron and researched relativity of its Influencing facto, the results showed that the average content of available boron in the yellow soil was 0.39±0.27 mg/kg, 80 percent of its was under 0.5mg/kg which was lack for boron and 17.44 percent of its was under 0.2mg/kg which was especially lack for boron; The distribute frequencies of available boron contents of yellow soils in Chongqing was dispersedly, its range of 0.07mg/kg to 1.99mg/kg. The diversity of different zoology area was distinct. The result of pertinence analyses showed that available boron contents had correlativity with the pH(r=0.181** n=281) and CEC（r=0.124** n=281 and It had correlativity with Organic matte When the content of organic matte is high; in addition, soil granule、clime was the Influencing factor of availability of boron in Yellow Soils in Chongqing.

笔者通过调查取样对重庆市黄壤硼的含量进行测定并分析了缺硼的程度，对其影响因素进行了相关性分析，研究结果表明：重庆市黄壤有效硼的平均含量为0.39±0.27mg/kg，其中近80%的土壤样品有效硼含量低于0.5mg/kg，属于低硼或缺硼土壤，还有17.44%的土壤样品有效硼含量低于0.2mg/kg，属于极度缺硼的土壤；而有效硼含量的分布频率比较分散，变幅较大，从0.07mg/kg~1.99mg/kg，变异系数达到69.41%，不同生态类型区土壤有效硼含量的差异十分明显；而相关性分析结果表明：土壤有效硼与土壤pH值(r=0.181** n=281)和CEC（r=0.124** n=281呈正相关，在有机质含量较高的条件下与其相关性也较为显著（r=0.347** n=90，而土壤质地以及气候也对重庆市黄壤硼的有效性有很大的影响
