  • 摘要: 采用室内培养和吸附解吸两种方法,研究了石灰性褐土中磷、锌交互作用.培养试验表明,在本研究浓度范围内,施磷明显提高了土壤中DTPA提取态锌含量,提高率为15%—134%,且这种作用在培养前3天之内就已经很明显,在整个培养期比较稳定.施锌也增加了磷的有效性,这种作用随着时间的延长(培养的第7天始)逐渐增强.施锌可减缓有效磷随培养时间的延长呈明显下降的趋势.吸附试验表明,石灰性褐土磷含量或磷吸附量的提高均可降低其对锌离子的吸附容量和吸附能力.吸附磷提高了KCl解吸的活性较高的锌量,降低了HCl解吸的专性吸附态锌(活性很低的锌)量,即磷含量(吸附量)增加了土壤中锌的有效性.因此,石灰性褐土中磷锌交互作用为协同作用.
    Abstract: The interaction of phosphorus with zinc in calcareous cinnamon soil was investigated by incubation method and batch equilibrium techniques. The results showed that application of P significantly increased the DTP A-Zn concentration in the soil from 15% to 134%, and the effect was evident on the first 3 days and was steady during the entire trial period (90 days). Application of Zn also significantly enhanced available P concentration, but the effect strengthened gradually with the incubation time (starting from 7th day). High P concentration or adsorption in calcareous soil decreased Zn adsorption capacity and adsorbability. High P adsorption increased Zn desorption by KCl, but decreased Zn desorption by HCl, i.e., higher level P in calcareous soil could promote the availability of Zn. Thereby, the interaction of P with Zn had synergetic effect in calcareous cinnamon soil.
