[目的]研究磷肥和石灰对红壤白三叶草、大翼豆和圆叶决明生长的影响,为推广白三叶草、圆叶决明和大翼豆的栽培提供理论依据。[方法]以白三叶草、大翼豆和圆叶决明为材料,于2010年采用土培盆栽试验,研究南方丘陵区酸性红壤上石灰和磷肥配合施用对其生长发育的影响。[结果]同一石灰用量下,施磷能明显提高供试牧草株高、总分蘖数和植株干物质量。不施磷处理下,1.4g/kg土的石灰用量下3种牧草植株总生物量最高,对红壤酸性改良效果最好;施200mg/kg土磷肥处理下,2.1g/kg土的石灰用量下白三叶草和大翼豆植株总生物量最高,1.4g/kg土的石灰用量下圆叶决明植株总生物量最高。[结论]该试验结果对白三叶草、大...

[Objective] The aim was to research effects of P fertilizer and lime on growth of Trrifolium repens, Chamaecrista rotundifolia and Macroptilium atropur- pureum, to provide references for cultivation of the three plants. [Method] Pot experiments were conducted with Trrifolium repens, Charnaecrista rotundifolia and Macroptilium atropurpureum in 2010 in order to research effects of lime and P fer-tilizer mixture on growth of the plants in southern hilly acidic red soils. [Result] With lime amount fixed, application of P fertilizer would enhance plant height, total tiller number and dry matter. Wh...
