摘        要
 廣州地區秋季在沙基質上建植粵選1號匍匐翦股穎（Agrostis stolonifera L. cv. Yuexuan No.1）果領草坪，采用泥炭土與沙按照體積比0、1%、2.5%、5%、10%分別混合沙基質厚度5cm、10cm。測定成坪期果領草坪生物量、剪草量、草坪密度、根系長度、草坪色澤及成坪時間。結果表明，沙基質中混入泥炭土2.5%，基質物理性狀適中，總孔隙度為33.26%、通氣孔隙度為2.66%、持水孔隙度為30.6%、持水量為188.4g/kg；沙基質中混合泥炭土，有利于粵選1號匍匐翦股穎成坪；沙基質中混入泥炭土2.5%，混合土層厚10cm時，果領成坪時間39d，地上與地下生物量分別為4.02gDW/dm2和7.88gDW/ dm2，密度11.9株/cm2，草坪色澤深，草坪草剪草量大。

 the Growth Conditions of Green Lawn of Agrostis stolonifera L. cv. Yuexuan No.1 in Different Matrix

Abstract：The green lawn of Agrostis stolonifera L.cv.Yuexuan No.1 was established in matrix of sand in the autumn in Guangzhou.  Peat was mixed with sand in accordance with volume ratio 0, 1%, 2.5%, 5%, 10% to thickness 5cm and 10cm respectively. The green lawn of biomass, weight of grass cutting, lawn density, root length, turf color and the time of the lawn completed were researched. The results show that the physical shape of matrix of the treatment of volume ratio 2.5% is moderate, the porosity is 33.26%, ventilation porosity is 2.66%, water porosity is 30.6%, water holding capacity is 188.4g/kg. It was benefit for Agrostis stolonifera L.cv.Yuexuan No.1 to be a lawn using peat mix with sand. Used peat and sand in accordance with volume ratio 2.5% and mixed layer thickness of 10 cm, turf grass growing time was 39d, the biomass of above and below ground reach 4.02gDW/dm2 and 7.88gDW/dm2 respectively, the lawn density was 11.9 strain/ cm2, turf color was deep, and the growth of turf grass was large.
