浦绿和卡丽芭对匍匐翦股颖草坪的节水效果研究
|
摘要
研究了浦绿和卡丽芭在3种不同基质中对匍匐翦股颖(Agrostis stolonifera L.)节水效果的影响。结果表明,在无机改良基质中,浦绿和卡丽芭对草坪的节水效果不显著。而在纯沙和有机改良基质中,浦绿通过降低草坪的生长高度,从而降低了草坪的整体蒸散量,最终减少了草坪的灌溉量,达到一定的节水效果;而卡丽芭则通过减少土壤水分蒸散量,从而减少草坪灌溉量,达到节水效果。
The effects of primo and qualibra on water-saving effects of creeping bentgrass were studied in three different substrates.The results showed that in the inorganic modified matrix,primo and qualibra had no significant water-saving effect on the lawn.In the pure sand matrix and organic modified matrix,primo decreased the overall evapotranspiration of lawn by reducing the growth height of lawn, and eventually reducing the amount of irrigation of the lawn to achieve a certain water-saving effect;while qualibra reduced the amount of irrigation by reducing soil evapotranspiration,thus achieving water-saving effect.
