Abstract: The purpose of this research was to examine the effects of soil moisture content to the evapo-transpiration(ET)and growth of turf grass growing under pot experiment.Three different soil moisture treatments were designed: A1:70%-85% field capacity(FC),A2: 55%-70% FC,A3:40%-55% FC.The result shows that the evapo-transpiration rose with the soil moisture increased.The Poa pratensis turf with A1 treatment lost the greatest amount of water;followed by A2.A3 treatment suffered the least.Results regarding the above-ground and under-ground biomass were also significantly influenced(P<0.1)by the soil moisture content.

摘要： 研究了土壤水分对草坪蒸散和生长的影响。结果表明:水分条件能显著影响(P<0.1)草坪草的蒸散,供水多,蒸散量大,供水少,蒸散量小;土壤含水量为田间持水量70%-85%时,草地早熟禾(Poa pratensis)蒸散量最大,55%-70%,次之,40%-55%最低。草坪草叶面积指数、地上和地下生物量均与土壤含水量呈显著的正相关。
