广州地区几种草坪草冬季坪用性状研究

几种草坪草秋季建坪试验说明，匍匐翦股颖新品系（粤选2号、粤选3号、粤选4号）、狗牙根、伪针茅、长花马唐草坪成坪速度较快，草坪致密，假俭草、马尼拉、地毯草难以成坪，草坪稀疏。长花马唐、匍匐翦股颖新品系色泽深，根系活力较高。冬季草坪草膜透性根系> 匍匐茎>叶鞘>叶片，马尼拉、伪针茅、假俭草膜透性总体上较高。

Turf Character of Some Grasses in Guangzhou Area in Winter

Experiment was conducted to study the turf character of some grasses through turf establishing in autumn. The results showed that Agrsostis stolonifera(new strain Yuexuan No.2, Yuexuan No.3, Yuexuan No.4), Cynodon dactylon, Pseudoraphis spinescens, Digitaria longiflora had rapid vegetative turf establishment for dense turf. Eremochloa ophiuroides, Zoysia matrella, Axonopus compressus had slow vegetative turf establishment for thin turf. Digitaria longiflora and new strain Agrsostis stolonifera had dark green color and high root vigor. The relative membrane permeability in winter was root>creeping stolon>sheath>leaf blade. Zoysia matrella, Pseudoraphis spinescens, Eremochloa ophiuroides had high relative membrane permeability overall.
