冷地型混播草坪在不同基肥处理下的坪用性状比较

Turf Performance of Cold-Season Turfgrass under Different Basal Fertilizers

试验对菲尔金早熟禾 (Fyking)、多年生黑麦草 (Derby)、猎狗高羊茅 (Houndog)以 5∶3∶2的混播比例组成的草坪和 4种不同基肥 (Ⅰ 不处理、Ⅱ 尿素 +磷二铵、Ⅲ 尿素、Ⅳ 磷二铵 )处理 ,结果表明 ,在林芝地区地理及气候条件下用尿素 +磷二铵作为基肥建植冷地型草坪时其坪用性态最佳 ,其次为磷二铵 。

treatments of basal fertilizers, i.e. non fertilizers (Ⅰ), Urea+ammonium phosphate (Ⅱ), urea (Ⅲ), ammonium phosphate (Ⅳ)were applied on mixture turf of fyking kentucky bluegrass, perby perennial ryegrass and Houndog tall fescue in proportions of 5∶3∶2. The results show the performance of the turf were best under urea + ammonium phosphate treatment, and worst at non fertilizer treatment.
