| 摘 要： | 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ＰＨ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。

| Abstract: | Pot experiment was carried out to investigate the property of B and Mo uptaken by peanut and the variance of soil available B and Mo content after B and Mo depletion on 6 soils cultivated peanut in Guangdong province. The results showed the amount of B uptaken decreased significantly, as reaching the minimum value the soil available B increased with the increase of the B depletion times. Among depletion experiments, there were no remarkably changes of Mo uptaken amount and the soil available Mo content although the soil pH value increased significantly with the increase of the Mo depletion times. The changes of soil available B and Mo content had not significant relation with B and Mo uptaken by peanut. |
