Fig. 4From: Moderately prolonged dry intervals between precipitation events promote production in Leymus chinensis in a semi-arid grassland of Northeast ChinaThe dynamics of soil water content in pots during the experimental period. a, b and c represent decreased (− 30%), control and increased (+ 30%) rainfall amounts, respectively. The different colored lines represent different rainfall intervals. The inset indicates the mean soil water content (MSWC) under different rainfall amounts and dry interval treatments. Small letters indicate significant differences in MSWC between rainfall intervalsBack to article page
