| 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．

| 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. |
