Impacts of environmental factors on the production of non-soil turf in green house

Taking Festuca elata Keng as the experimental material,the effects of light,temperature (℃)，humidity (%),nutrients and water conditions of sediments and the application of plant hormone (IBA and Paclobutrazol) on the production of non-soil turf in green house are studied. The results indicate that in order to improve the quality and rolling of turf,the temperature should be controlled between 15℃ and 25℃ and the temperature difference should be kept between day and night;the relative humidity should be between 40% and 60%，and 50%～60% is more benefit to the development of roots;the illumination should be kept above 15000 lx;suitable fertilizer and plant hormone could be used as a micro-adjusting measurement.
