春逸

树种：长芒草	学名： Stipa bungeana‘Chunyi’
类别：品种	通过类别：认定（3年）
编号：国R-SV-SB-010-2008

品种特性

冷季型宿根草本植物。基生叶形成厚密的株丛，高20cm左右，成株冠幅45-50cm。春季观花，圆锥花序开展飘逸，此时株高约60cm；自然花期为4月下旬至6月中旬。在北京地区3月10日左右萌芽，11月初枯黄，绿色期230余天。该品种喜光，夏季不休眠。

暖季型观赏草。成株高1.5m-1.8m，冠幅1m有余。叶片具乳白色的条纹，弧形，向四周下垂，几近地面，形成浑圆的株形。顶生圆锥花序呈指状，本品种需要长时间的炎热季节才能开花完全，在华北地区秋季开花，不能产生成熟的种子。分株为主要繁殖方法。

栽培技术要点

适宜采取分株方式繁殖。春季为最佳繁殖时期，在北京地区，4月中、下旬将根系全部挖出，抖去泥土，剪掉须根，按照5-10个分蘖数分开，以70m×70cm的株行距栽植在繁殖田里。此时幼芽刚萌动，分株时注意不要破坏芽点，以保证栽植成活率和其后的长势。田间栽培‘花叶’芒，以壤土最好。栽培深度以10cm-15cm为宜。移栽后及时浇一次透水保证成活。‘花叶’芒耐旱，在华北地区基本不需补充灌溉。若盆栽，基质以壤土混合草炭土为宜，每年4月中、下旬移栽到30厘米口径的瓦盆或营养钵中。盆栽需根据植株的生长情况及时浇水、追肥。追肥以速效肥为主，结合降雨或灌溉进行。

适宜种植范围
