| Abstract/Contents: | "The effects of nitrogen form and concentration on the growth, leaf physiology and lawn quality of perennial ryegrass (Lolium perenne) under drought stress were investigated by hydroponic experiment. In the experiment, four drought levels were set, three nitrogen forms (urea, calcium nitrate, ammonium sulfate) were set, and the concentrations of three forms of nitrogen were 0, 0.4, 0.8, 1.2 and 1.6 g/L, respectively. The results showed that three different forms of nitrogen could increase the leaf surface area, leaf length, relative water content and chlo-rophyll content of perennial ryegrass, while decrease its root-shoot ratio and the relative conductivity of perennial rye-grass under drought stress, among which 1.6 g/L nitrogen concentration was the best. The results also demonstrated that under severe drought stress,among the three forms of nitrogen, calcium nitrate showed the best performance in increasing the above-ground part of perennial ryegrass. The leaf surface area and leaf length under 1.6 g/L calcium nitrate treatment increased by 31.04% and 53.87% compared with those without nitrogen treatment. Ammonium sulfate had the best effect in decreasing relative electrical conductivity and increasing chlorophyll content of perennial ryegrass leaves, which decreased by 54.65% and increased by 26.51%, respectively, compared with nitrogen free treatment. However, Urea was the best in increasing relative water content of perennial ryegrass leaves. The relative water content of perennial ryegrass leaves was increased by 31.04% in 1.6 g/L urea treatment compared with no nitrogen treatment." |
