| 摘 要： | 盆栽试验结果表明，酸性土壤上适当施用石灰能极显著提高吞豆的疸。云南赤红壤方解石用量在3.0g/kg时，吞豆产量达到最佳；云南黄红壤白云石用量为2.8g/kg时，蚕豆的籽粒产量接近峰值，地上部干重达到最佳；湖北咸宁棕红壤方解石与白云石混合用量在1.5g/kg时，吞豆获得最佳产量。供试土壤施用石灰可以提高土壤pH。显著降低了土壤活性铝和活性锰；此外，施用石灰改善了供试土壤的磷营养，磷营养差异是蚕豆产量差异的主要原因之一。

| Abstract: | In potted plant experiment, proper dosage and kinds of lime application significantly increased the yield of broad bean in the acid soils. The yield of broad bean arrived at the summit at the same time when calcite dosage was 3.00 g/kg in laterite; the seed yield was near to and the upside yield came to its peak value when dolomite dosage came to 2.80 and 3.50 g/kg in yellow-red soil; the yield came to peak value simultaneously when (calcite + dolomite) dosage was 1.5 g/kg in brown red soil. Lime application increaed soil pH and reduced soil activated aluminum and activated manganese of the tested soils significantly. Besides these, lime application improved soil phosphorus nutrition, which was one of the main causes that increased the yield of broad bean. |
