Over ground and Underground Development of Alfalfa in Establishment Period
Journal Title: Scholars Journal of Agriculture and Veterinary Sciences - Year 2015, Vol 2, Issue 5
Abstract
Abstract: The characteristics of the over ground and underground growth of Algonquin alfalfa were observed and analyzed through a pot experiment method. The results showed that under the condition of sufficient water and fertilizer, alfalfa on the ground and underground biomass during the planting period continues to accumulate. In this process, the cumulative speed and amount on the ground was superior to the underground: The average ground biomass cumulative speed was 8.8 times of the underground; at the mowing before winter, on the ground and underground dried biomass per plant was 0.51 g and 0.18 g respectively. Alfalfa’s length development was closely related to the daily average temperature change over time. The largest plant height growth rate on the ground was corresponding to a daily average temperature of 23.69 ℃, while that of the underground root length’s was 15.49 ℃.
