不同覆膜时间对复式草皮生产的影响

The influence of covering time on sod production of double sheets turf

在5个不同的时间(9月15日,10月1日,10月15日,10月30日,11月15日)覆盖处理冬季复式草坪,研究其对高羊茅和百慕大草坪组合的影响。通过对成坪时间、草坪质量、经济效益等综合因素的比较,采用LSD的最小差数显著法和灰色系统中的关联系数分析法得出,处理Ⅲ覆膜为最佳时间,处理Ⅱ其次,处理Ⅴ为最差。通过该试验可知在进行冬季复式草坪生产时,最好的覆膜时间为十月中上旬。

In this paper, the influence of covering time （September 15, October 1, October 15, October 30, November 15） on the winter composite turf of Festuca arundinacea and Lolium multiflorurn L. cv. Barmultra were studied. By comparing turf-forming time, turf quality, economic efficiency and other factors,and using LSD and Vague System,the results shown at treatment （October 15） was the best, （October 1） was better and （November 15） was the worst. Based on this experiment,it could be determined that the best covering time of winter composite turf inshanghai region was early October.
