摘　　要：对桉树苗生产冬季补光进行分析研究,确定补光强度、补光时机、补光光源,对温室育苗补光进行实地试验。结果表明:补光强度宜在200μmol.m-2.s-1范围内,补光应在室内温度15℃以上进行才有较好效果,当室内温度低于11.5℃时,补光效果为零;农用生物补光钠灯是苗木冬季补光较理想光源。对补光的成本进行核算,在不补光情况下每株苗成本0.164元;在补光情况下每株苗成本0.158元。通过补光,苗木的等级得到提高,生产周期加快。Light supplement for Eucalyptus seedling production in winter had been analyzed and studied to make sure that the light intensity,time and source were suitable for filling in.Then a site trial had been conducted and the results indicated that the light intensity was appropriate within 200 with the room temperature above 15℃ to get a better effect.There was no effect if the room temperature was below 11.5℃.The ideal light source for supplement in winter was agricultural sodium lamp.Through light supplement,the grade of seedlings was improved and the cycle of production was shortened in the evidence of the checked cost,which showed that the individual plant was 0.158yuan with the light supplement and 0.164yuan without.
