近几年我国应用电热温床育苗发展十分迅速。国内许多单位的研究和生产示范都已证明了电热温床能有效地解决早春育苗地温低的矛盾,因而使育苗天数比常规育苗法缩短25～30％,能耗降低20～30％,同时提高了秧苗质量及壮苗百分率,平均每亩增产率可达20％左右。但是电热温床的温度变化规律,电热温床的功率选定,温度和用电量的关系等是生产上迫切需要解决的问题,为了更有效地应用电热温床育苗,进一步降低育
In recent years, China’s application of electric hotbed nursery development is very rapid. Many domestic units of the research and production demonstration have proved that electric hotbed can effectively solve the early spring nursery ground temperature is low contradictions, thus raising the number of nursery days than conventional nursery shortening 25 ~ 30%, energy consumption decreased by 20 to 30%, while improving Seedling quality and strong seedling percentage, the average yield increase of about 20% per mu. However, the hot temperature bed temperature changes, electric hotbed power selection, the relationship between temperature and power consumption is the production of urgent problems to be solved, in order to more effectively use electric hotbed nursery, to further reduce education
