摘要: 采用地下渗滤系统,通过盆栽模拟试验研究了不同用量沼肥对高羊茅(Festuca arundinaces Schred.)草坪质量及生长的影响,探索沼肥在草坪上应用的可能性。结果显示:随着沼肥用量的增加,不同处理之间的草坪颜色质量、草屑带出总量、草屑中氮磷养分带出量均存在显著差异(P<0.05)。在相同氮素用量200 kg N·hm-2下,化肥处理的表现优于沼肥处理,这可能与二者施用方式不同有关。当沼肥用量由200 kg N·hm-2增加为1400 kg N·hm-2时,草屑带出总量、草屑中氮、磷养分带出量分别增加了2.0,3.4和2.2倍,表明草坪在消纳利用沼肥方面具有较大的潜力。

Abstract: Effects of different biogas fertilizer on turf quality and growth was investigated using simulation tests with a subsurface infiltration system.Results showed that the turf color quality,the total clipping amount and N,P values had significant differences between treatments biogas increased.Under the same amount of 200 kg N·hm-2,the quality of chemical fertilizer treatment was better than biogas fertilizer treatment.It may result from different application methods for two treatments.With biogas fertilizer application increasing from 200 kg N·hm-2 to 1400 kg N·hm-2,the total clipping amount and N,P values increased 2.0,3.4 and 2.2 times,respectively.These results indicated potential for biogas fertilizer application on turf growth.
