摘    要:紫花地丁(ViolayedoensisMakino)具有较高的观赏价值,有较强的抗逆性.本试验旨在选用紫花地丁作为缀花草坪植物.对其进行逆境指标研究的试验证明:紫花地丁践踏后恢复再生能力较强,能抗8.78kg/cm2的土壤坚实度,土壤含水量在5%~8%仍能生长.土壤含盐量0.3%时生长未受影响,并能耐5d以上的水淹,比较接近草坪品种选育的指标.

关 键 词:紫花地丁  抗践踏性  抗涝性  抗旱性  抗盐性  指标

Abstract:viola yedoensis Makino is valued Makino for its ornament and adverse cirumstancesresistance. It is aimed at selecting viola yedoensis to be embellishment cawn plant. It was revealed that: viola yedoensis Makino had a high reviving ability after trampled and could resist 87kg/cm2 solid degree of soil. It could grow normally when there was 5 %~8% moisture content and 0. 3 %salt cantent. It could be drowned for 5 days and approached the level of lawn variety.
Keywords:viola yedoensis Makino   trampling-resistance   flood-resistant   drought-resistan   saltresistant   index
