Quantitative analysis on the relationship between the above-groud biomass and density in the population of Puccinillia chinampoensis in the alkalized meadow in the Songnen plain of China
Puccinillia chinampoensis is fine grass that tolerates to salt. It spreads widely in Songnen plain of China, and often develops consociation. The analytical results showed that there the linear function or power function between three mean tiller mass and the density in earing stage, the linear function between mean seeding mass and the density, the exponential function or power function between flower heads mass, above-ground biomass ratio and the density, the linear function or power function between yo...
