土面增温剂是一种覆盖型水分蒸发抑制剂,它能抑制水分蒸发,减少热量消耗,从而提高地温。在中国科学院地理研究所等单位协助下,我社1973年进行了将土面增温剂用于水稻育苗的试验。结果表明:土面增温剂对于提早出苗、培育壮秧和降低生产成本,效果比较明显。 Soil warming agent is a covered moisture evaporation inhibitor, which can inhibit the evaporation of water, reduce heat consumption, thereby increasing the ground temperature. With the help of the Institute of Geography, Chinese Academy of Sciences and other units, our company conducted the experiment of using soil warming agent in rice seedling breeding in 1973. The results showed that: soil surface warming agent for early emergence, seedling culture and reduce production costs, the effect is obvious.
