Influences of liming on life form and ecological behaviour of plant community in low productive grassland

低位生産 草地에서 石灰施用이 植物群落의 生活型과 生態的 反應에 미치는 影響

This experiment was carried out to investigate the effect of liming on life form and ecological behaviour of stand in low productive grassland with acidified solil at dairy fram in yesan, chungnam province. The inferior plant community of low productive grassland was improved to the most desirable pasture association with herbage of 84% by liming. the life forms of association in low productive grassland were composed of hemicryptophytes of 49.4%, therophytes of 48.2%, geophytes of 2.2% and chamaephytes of 0.2% but by liming their life forms of hemicryptophytes increased greatly by 32.6%, on the other hand geophytes were much more decreased by 33.4%. The ecological behaviour of moisture figure and nitrogen figure were slightly increased and soil reaction figure was gradually decreased in low productive grassland by liming.
