Effects of mowing on alfalfa and Bromus inermis mix-sowing grassland
Effects of mowing of first-year planted alfalfa and Bromus inermis mixture grassland on its growth in next year were analyzed in the study. The results showed that plant height reduced with the increasing of mowing frequence in re-green period in next year; total yield and photosynthetic rate of fisrt-stubble of alfalfa decreased while Bromus inermis increased with increasing mowing frequency; alfalfa yield up to highest in the next year when moving happened at early florescence in the first year. Yield of first-mowing and photosynthetic rate of Bromus inermis decreasing while photosynthetic rate of alfalfa increasing when fisrt-mowing time was prolonged.
