环境因素对大棚温室无土草坪生产的影响研究

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

以冷季型草种高羊茅(Festuca elata Keng)为材料,研究光、温、湿度、基质肥水条件以及植物生长素对大棚温室草坪生产的影响结果表明,温度宜控制在15～25℃,且昼夜应保持一定温差;湿度宜在40％～60％间,为促进根系生长应控制在50％～60％间;光照应保持在1.5万lx以上;适当施肥补充养分和运用植物生长素可作为环境微调措施,有利于提高草坪质量和快速成卷。

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.
