1　火烧强度对种子的影响研究表明 ,大部分树木种子能耐较高的温度 ,并且树木种子经过一定的温度处理后 ,种子萌发能力会显著增强。如果树木种子被土壤轻轻埋藏 ,即使强度较大的火烧后 ,种子也不会失去生命力 ,甚至经过火的高温处理后 ,树木种子的发芽率还会提高。对于草地火来 1 The effect of fire intensity on seeds The research shows that most tree seeds can tolerate higher temperatures, and the seed germination ability of tree seeds can be significantly enhanced after being treated with certain temperature. If the tree seeds are gently buried in the soil, the seeds will not lose their viability even after the intense fire, and the germination rate of the tree seeds will increase even after the heat treatment of the fire. For the grass fire
