为了研究不同品种黑麦草在不同氮素水平下的生理特性变化,试验选取4个黑麦草品种(辛普利草业公司提供的卡特、爱森特、太阳岛、托亚4个品种),在生长过程中施用不同浓度氮素,测定了相关生理指标。结果表明:4个黑麦草品种中太阳岛的氮素利用率最高,植株内积累的生物量最多、生活力最强、表观性最好;爱森特次之;托亚和卡特整体表现稍差,二者结果相似。
In order to study the physiological characteristics of different varieties of ryegrass at different levels of nitrogen, four ryegrass varieties (Carter, Eisentec, Sun Island, Tuoya 4 varieties) The growth of different concentrations of nitrogen applied to determine the relevant physiological indicators. The results showed that: the four ryegrass cultivars Sun Island nitrogen utilization rate of the highest accumulation of plant biomass, the strongest vitality, the best apparent; followed by love Center; Tony and Carter overall slightly Poor, the two are similar.
