Abstract: Soil amendments are usually added to the rootzone materials of golf course to improve its water holding capacity and nutrient condition.In order to choose proper amendments for golf course rootzone,three organic soil amendments were mixed with the sand to compare the influence on the growth of creeping bentgrass(Agrostis stolonifera L.).The pot experiment results show that the speed of turf growth was increased significantly by addition of the German peat and wormcast.Compared with the pure sand treatment,the turf establishment time was shortened by 24 days for German peat and 17 days for wormcast.There were significantly increases in the clipping amount,the total biomass weight,and the nutrient contents under the treatments of German peat and wormcast.The local peat had no significant influence on the growth of creeping bentgrass.The main reason could be the property difference of the three organic soil amendments,such as the organic matter content and cation exchangeable capacity.

摘要: 为改善高尔夫球场果岭砂基坪床保蓄能力差的弱点,通常需要添加一定比例的改良物质。因此,系统研究3种有机改良物质对果岭草坪草生长的影响,为球场建造过程中科学地选择改良物质提供理论依据。结果表明:添加德国草炭、蚯蚓粪的处理能够显著提高草坪成坪速度(P<0.05),与对照处理相比,成坪时间分别提前了24d和17d,而国产草炭对草坪成坪速度无显著影响。德国草炭、蚯蚓粪处理可以显著增加草坪的草屑量、总生物量以及养分吸收量(P<0.05),而国产草炭则无促进作用。分析造成差异的原因可能与改良物质本身的品质,如有机质含量、阳离子交换量等有关。
