电热温床温度控制不仅直接影响蔬菜秧苗的生长,而且也影响耗电量的多少,因此,控制适宜的温度是电热温床育苗的关键性技术措施之一.一、温度计和控温仪的校正采用电热温床育苗,必须准备1支普通玻璃温度计,由于有的温度计误差较大,在使用前应进行校正.技正方法,以用温度表校正最好,否则,
Electric hotbed temperature control not only directly affect the growth of vegetable seedlings, but also affect the amount of power consumption, therefore, to control the appropriate temperature is hot electric hotbed breeding one of the key technical measures.A thermometer and temperature controller calibration using electric heating Hotbed nursery, you must prepare an ordinary glass thermometer, due to some large error of the thermometer, should be corrected before use. Technical methods to correct the best thermometer, otherwise,
