采用实验室接种培养方法,研究了施用石灰对水溶性磷、无机磷组分的转化和酸性土中Bray-1有效磷的影响。结果看出:施用石灰能显著地增加未施磷土壤的水溶性磷或速效磷,以增加未施磷和施用磷肥土壤的铝磷盐组分( fraction)。但对土壤中铁和钙磷盐组分的影响,则相对地少得多。酸性土壤施用石 Laboratory inoculation culture method was used to study the effect of lime on the conversion of water-soluble phosphorus and inorganic phosphorus and the available Bray-1 in acidic soils. As a result, it was found that application of lime significantly increased water-soluble phosphorus or available phosphorus in the non-phosphorus-containing soil to increase the aluminum-phosphorus fraction of the soil to which phosphorus was not applied and in which phosphorus was applied. However, the effect on iron and calcium phosphate components in the soil is relatively much less. Acid soil application stone
