取广东省花生主产区 6种代表性土壤进行花生硼、钼耗竭试验 ,研究花生吸硼、吸钼特性及土壤有效硼、钼含量的变化。结果表明 ,随栽种次数增加 ,花生植株吸硼量显著下降 ,土壤有效硼含量表现先降后升的趋势。耗竭过程中 ,植株的吸钼量和土壤有效钼 ( Tamm’ s态钼 )含量变化不明显 ,但土壤 p H值表现极显著上升。土壤有效硼、钼含量变化与植株吸硼、吸钼量无密切关系 Six kinds of representative soils in peanut main producing areas of Guangdong Province were used to carry out the experiments of boron and molybdenum depletion in peanut so as to study the changes of boron and molybdenum sorption characteristics and available boron and molybdenum contents in peanut. The results showed that with the increase of planting frequency, the boron absorption of peanut plants decreased significantly, and the content of available boron decreased firstly and then increased. During the process of depletion, the amount of absorbed molybdenum and the content of soil available molybdenum (Tamm’s molybdenum) did not change significantly, but the soil p H value showed a very significant increase. Soil available boron, molybdenum content changes and plant boron, absorb the amount of molybdenum is not closely related
