应用电热温床育苗近几年发展很快。因为它有效地解决了早春育苗地温不足的矛盾,从而使育苗时间缩短,育苗成本降低。但是,由于植物生长受气温影响,气温对电热温床的用电量又有很大影响。所以气温与地温必须很好的配合,才能更有效地缩短育苗天数又比较省电。这是目前大量推广应用电热温床育苗必须十分注意的问题。我们在不同气、地温对果菜秧苗影响的试验中发现,出苗前地温起主导作用,这段时间,地温应设定在24～25℃比较好,苗出得快又齐。
Application electric hotbed nursery developed rapidly in recent years. Because it effectively solves the problem of lack of ground temperature in early spring nursery contradictions, so that the breeding time is shortened, reducing the cost of nursery. However, due to the influence of air temperature on plant growth, the temperature has a great impact on the electricity consumption of the electric hotbed. Therefore, the temperature and ground temperature must be well coordinated in order to more effectively reduce the nursery days and more energy-efficient. This is a large number of popularization and application of electric hotbed breeding must pay great attention to the problem. We in different gas, ground temperature on fruit and vegetable seedlings in the experiment found that pre-emergence ground temperature plays a leading role, this time, the ground temperature should be set at 24 ~ 25 ℃ is better, the seedlings out quickly and Qi.
