| 摘 要： | 通过试验对生物质气化发电的副产物--生物质气化灰的肥效进行研究.结果表明,在施肥量相同的条件下,添加生物质气化灰的试样,除黄瓜外,空心菜、油麦菜、樱桃萝卜、上海青试样的发芽时间都略早于单施化学肥料的试样; 后期长势也明显优于单施化学肥料的试样,叶片厚而有光泽; 前者在生长过程中没有虫害现象,后者有虫害现象.在生物质气化灰中添加氮、磷的试样比施单一肥料的试样长势好.研究表明,生物质气化灰具有替代钾肥的广阔市场前景.

| Abstract: | This paper is concerned about its authors' experimental study for the fertility of the biomass ash by gasification as a by-product of the biomass power plant. The results show that the germination time of the samples added to the biomass ash by gasification except cucumber proves to be sooner than that only applied to the chemical fertilizer plant. Since the biomass ash made by the gasification not only had rich content of K but also contains rich nutrition of Ca,B and other trace elements. In addition,the ... |
