摘要
冰点以下的低温伤害草坪植物细胞,裸体冰冻的半致死温度是-8℃至-15℃,而在2.5厘米土体中冷冻则是-15℃至-20℃。由细胞伤害率的测定资料配以Logistic方程求出拐点温度,即为各草种的临界温度值。
Low temperatures below freezing point damaged turf plants cells. Aerial seami-death temperature was -8℃ to -15℃, in earth deepth of 2.5 cm was -15℃～-20℃. Cell damage rate data combined with Logistic equation the inflection point was calculated as the critical temperatures.
