加快高羊茅草坪成坪的技术探讨

STUDIES ON THE GROWTH OF GRASS CARPET OF Festuca arndinacea

为解决在绿化施工过程中因工期短 ,而又要求草坪在短期内取得较好的绿化效果的实际问题 ,进行了室内高羊茅种子催芽及幼苗期化学处理等试验。试验发现 ,高羊茅草籽进行温水 (33℃ )催芽后再播种 ,可使出苗期缩短 10d左右 ,对幼苗适当喷施 2 0mg L 92 0、 10 0 0mg L磷酸二氢钾、 10 0 0 0mg L尿素 ,能明显促进草坪幼苗生长 ,大大缩短成坪时间。

The methods for promoting growth of Fesruea arndinacea Schub were studied in this paper,It was helpful for the seed germination and seedling formation to soak the seeds in 33℃ water before sowing, and the period of seedling formation was about 10 days shorter than that of seeds without soaking treatment.The chemicals of 20 mg/L 920,1 000 mg/L KH 2PO 4 and 10 000 mg/L urea which were sprayed on leaves showed apparently positive effects on promoting growth of grass carpet of Festuca arndinacea Schub .
