摘要
为解决常规的大棚育苗对外界气温光照依赖性大、苗床时间长、烟苗素质弱、不利烟苗迅速返苗的技术难题,利用锅炉加温来人为地调节烟苗育苗的环境温度。试验结果表明,补光可促进烟苗生长,全天补光时烟苗生长效果更佳。
In order to solve the technical problem of greenhouse seedling to the outside of conventional light temperature dependence, long bed time, weak tobacco seedling quality, quickly returned to the shoot length, the boiler heating is used for tobacco seedling raising temperature adjustment. The results showed that the supplemental lighting could promote seedlings growth, with supplemental light smoke seedlings grew better throughout the day.
