肯塔基、瓦巴斯草地早熟禾在青岛地区的引种栽培研究

INTRODUCTION AND CULTIVATION OF POA PRATENSIS CV.KENTUCKY AND POA PRATENSISCV.WABASH IN QINGDAO REGION

青岛地区自１９８１年引种肯塔基单地早熟禾（Ｋｅｎｔｕｃｋｙｂｌｕｅｇｒａｓｓ）、瓦巴斯草地早熟禾（Ｗａｂａｓｈｂｌｕｅｇｒａｓｓ）之后，经对其形态学、生物学特征和特性的观察和试验，确认该草不仅具有耐寒、耐瘠薄、抗旱、返青早、枯黄晚、绿期长（３００ｄ以上）的特点，而且色泽鲜艳、草层厚来、繁殖容易、栽培简单，是建造草坪的一种优良草种。在大量栽培试验和推广实践的基础上，总结了肯塔基、瓦巴斯草坪草的播种、移栽技术，并重点介绍草坪形成后的除草、修剪、施肥、浇水等养护管理措施和延长青绿期的经验。

Poa pratensis cv. Kentucky and P. pratensis cv.Wabash were introduced to Qingdao region in 1984。Their morphology,biological characteristics and properties were observed and tested,the grasses wereconfirmed that they owned the characteristic of cold-tolerant,desert-tolerant,drought-resistant,reviving early,dead and yellow late and green period long(more than 300d),as well as in gay colours,thick and dense of grass layers,easy to propagate and cultivated simply.They were kinds of good grass seedsthat established turf.On the basis of quantity of cultivating test and extension practice,the sowing andtransplanting techniques of the turf grasses were summarized,and weeding,cutting,manuring,wateringetc。 measure of maintaining and managing and prolonging green period were mainly introduced。
