“抗旱剂一号”是河南省科学院化学研究所与生物研究所,共同研制出的一项科研成果,它从风化煤中提取出一种黄腐酸,喷施能增强作物抗旱能力。据目前调查,山西、河南两省风化煤中黄腐酸含量高达40％以上,这是一宗罕见的资源,是山西的优势。为今后抓好此项农业先进技术,现将抗旱一号的增产效果、施用方法等介绍如下: “Drought Resistant Agent One” is a scientific research achievement jointly developed by the Institute of Chemistry and the Institute of Biology of Henan Academy of Sciences. It extracts fulvic acid from weathered coal and can improve crop drought resistance. According to the current survey, the humic acid content of Shanxi and Henan provinces is as high as 40% or more, which is a rare resource and is Shanxi’s advantage. For the future do a good job of this advanced agricultural technology, anti-drought now on the number of production effects, methods of application are described below:
