摘要
通过论述种植在不同地区狼尾草(Pennisetum alopecuroides)的基本生物学特点,评价了狼尾草的适应性,同时探讨了狼尾草在各类园林中作为独赏、花境配置以及地被植物等应用的可能性。结果表明:狼尾草在北京地区可以安全越冬,同时具有很好的耐旱能力;狼尾草在天津滨海地带盐碱土中也能正常生长,具有较强的耐盐碱能力;在四川、陕西、山东等省也生长良好,整个生长期观赏效果俱佳。通过狼尾草种子扩散风险分析,表明狼尾草种子覆土13mm时发芽率最高,落在地表的种子大部分都失水而死亡,用于高尔夫球场高草区一般不会形成杂草,扩繁到其他区域。当狼尾草应用于高尔夫球场时,无论是单株独赏,成排种植,还是成片种植都有较高的观赏价值。
The adaptability of Pennisetum alopecuroides in different regions was evaluated and the applica-tion potential in garden landscape for single plant scenery,flower border or ground cover plants was discussed based on consideration of the basic biological characteristics.The results showed that Pennisetumalopecuroides not only is able to overwinter safely in Beijing,but also with good tolerance to drought.Moreover,it grow well in saline soil in Tianj in coast region that showed the good tolerance to salt and alkali.Furthermore,it preformed well and showed attractive scene during the whole growing season in Shanxi,Sichuan,Shandong Provinces.The study on the risk analysis of Pennisetumalopecurodies seeds spreading indicated that seeds under 1 3 cm soil lay-er showed the highest germination rate while most of the seeds on the surface soil died of water lackage.There-fore,it can rarely extend to other areas on golf course.
