Forage quality parameters of differently treated meadow plots (control, control +shelter), -25% precipitation, and -50% precipitation) on the moist and dry meadow site in the floodplain at the Rhine River.

The plots were cut in June 2011 and 2012 (first cuts; for second cuts of all but ME and NEL see Fig 3 and S1 Fig). Response parameters are biomass (g m-2), XF = crude fibre (% in dw), XP = crude protein (% in dw), DE = digestible energy (MJ kg-1 dw), ME = metabolisable energy (MJ kg-1 dw), NEL = net energy for lactation (MJ kg-1 dw), fructan (% in dw) and N-, P-, K-contents (mg g-1 dw); dw = dry weight. Values are means (x) + SE; n = 3. The right column indicates differences between moist and dry sites within years. Only P-content differs between treatment groups at the dry site in 2011 (different letters indicating significant differences at pForage quality parameters of differently treated meadow plots (control, control +shelter), -25% precipitation, and -50% precipitation) on the moist and dry meadow site in the floodplain at the Rhine River.试验样地分别于2011年与2012年6月完成首次刈割；除代谢能（metabolisable energy, ME）与泌乳净能（net energy for lactation, NEL）外的其余指标的第二次刈割结果详见图3与补充材料图S1。本数据集的响应参数包括：生物量（biomass，单位g·m⁻²）、粗纤维（crude fibre, XF，以干重百分比计，% dw）、粗蛋白（crude protein, XP，以干重百分比计，% dw）、消化能（digestible energy, DE，单位MJ·kg⁻¹ dw）、代谢能（ME，单位MJ·kg⁻¹ dw）、泌乳净能（NEL，单位MJ·kg⁻¹ dw）、果聚糖（fructan，以干重百分比计，% dw），以及氮（N）、磷（P）、钾（K）含量（单位mg·g⁻¹ dw）；其中dw代表干重（dry weight）。所有数值均为平均值（x）±标准误（standard error, SE），每组重复样本数n=3。表格右侧列展示了同一年份内湿润样地与干旱样地之间的组间差异。仅2011年干旱样地上的不同处理组间仅磷含量存在显著差异（不同字母表示组间差异具有统计学意义，P值）。本数据集涵盖莱茵河漫滩湿润与干旱草甸样地中，经不同处理（对照组、对照+遮雨棚组、降水量减少25%组、降水量减少50%组）的草甸样地的饲用品质参数。
