목초의 출아에 미치는 온도와 토양수분의 영향

Effect of Soil Moisture and Temperature on Emergence of Forage Grasses

The present study elucidates of the effect of less water stress in different temperature condition on the emergence of forage grasses. Water condition was controlled to 30% and 60% by water content by wet soil. The mean temperature is conducted by $10^{\circ}C$ (out side) and $20^{\circ}C$ (glass house). The results are as follows: 1. Mean emergence time and emergence day after sowing of grasses were greatly influenced by water content of soil and temperature. It was suggested that temperature was very important for the light competition with weed in the early growth of grass. 2. Accumulatied emergence of grasses was nat afected by temperature, but it was sensitively affected by water content of soil.
