北方早春繁育花卉时,常因低温而导致小苗大量死亡。为解决这个问题,以往生产者经常采用酿热加温、水热加温和火热加温法,但效果都不如电热加温好。其优点一是加热快;二是床温稳定,可根据需要人为控制或自动调节;三是不受气候的影响。电热加温就是通过地热线把电能转变为热能,对土壤进行加温的过程。设备主要由地热线和控温仪两部分 North early spring flowers, often due to low temperature caused a large number of seedlings died. In order to solve this problem, in the past, the producers often used stuffing to heat, water to heat and fiery to warm, but the effect is not as good as electric heating. First, the advantages of fast heating; Second, the bed temperature is stable, according to the needs of man-made control or automatic adjustment; Third, from the impact of the climate. Electric heating is through the geothermal power lines into heat energy, the process of warming the soil. Equipment mainly by the geothermal line and temperature control device in two parts
