冷炕白薯育苗是一种新方法,在我县深受贫下中农的欢迎。冷炕白薯育苗不用烧柴、烧煤,用骡马粪等酿热物使之发酵与阳光结合促秧苗发育。这种方法必须要把炕温掌握均匀,才能出苗齐、出苗壮、成活率高、产量高。因此,保证温度计的准确和正确使用,掌握调节炕温的规律,是保证冷炕育苗的关键问题。为解决这一问题,我站计量人员深入农村第一线和广大社员一起进行实验,在实践的过程中,我们体会到从薯种上炕到采秧可分为三个时期:一、薯种上炕初期,炕温不得低于23℃(指薯种周围土温)在23℃以下就会出现不出
Cold kang sweet potato seedling is a new method, in my county by poor poor middle peasants welcome. Cold kang sweet potato nursery seedlings do not have firewood, coal, mule horse manure and other fermented material so that the combination of fermentation and sunlight to promote seedling development. This method must take control of kang temperature uniform, in order to emerge Qi, emerging strong, high survival rate, high yield. Therefore, to ensure the accurate and correct use of the thermometer and to understand the regulation of the kang temperature is the key issue to ensure the nurturing of the kang kang. In order to solve this problem, we have experimented with first-rate metrologists in rural areas and with many members. In the process of practice, we realized that there are three periods between potato kang and pickling: first, On the initial stage of kang, kang temperature not less than 23 ℃ (refers to the soil around the soil temperature) below 23 ℃ will not appear
