退化草坪的更新与修复近几年，各大城市的草坪面积大增，使得草坪管理更为重要。很多时候，草坪因草坪草组成变化或表土介质理化性状的严重恶化而引起退化。为了节省人力、物力，可对草坪局部进行强度较小的改造和补植，这就是草坪的更新和修复。一、修复改良的必要条件1．草坪植被由完全可用选择性除草剂杀灭的杂草构成。2．草坪植被大部分由多年生杂草组成。3．因昆虫或致病因素或其他原因严重损坏的草坪。4．草坪有机质层过厚，土壤表层质地不均一，表层3至5厘米土壤严重板结。看到草坪退化，首先应弄清草坪退化的原因，才能对症下药，制定出正确、切实可行的方案。二、更新修复1．坪床制备坪床制备首先应考虑杂草防除采用除草剂。其次，进行深度垂直刈割，在极端情况下进行划破，以彻底破除有机质层。当表土板结不严重时，亦可进行高强度的芯土耕作和拖平。在耕作土壤前，应施复合肥料(含氮、磷、钾)，酸性肥料还应增施石灰，施量可视床土营养情况确定。2．草种选择修复可采用营养繁殖，但大多采用种子繁殖。应选择完全适应当地环境条件的草种，并要考虑草坪的一致性。3．种植播种方法常用撒播和圆盘播种。撒播采用标准播量，播后应浅耙和碾压。圆盘播种则用专用圆盘播种机完成，一般不用浅耙和碾压。（源自《中国花卉报》.09.28）
