1997年—1999年通过桶栽试验研究了粉煤灰改良砂姜黑土对冬小麦田生态因子的影响。结果表明，粉煤灰施入砂姜黑土降低了土壤的容重、比重及土壤的粘粒含量，增加了土壤的总孔隙度、毛管孔隙度和土壤饱和导水率。并分别得出土壤容重、比重、毛管孔隙度和饱和导水率与粉煤灰用量的模拟方程。同时，也对土壤温度、土壤含水量及土壤微生物数量在整个生育时期的变化动态进行了研究。 From 1997 to 1999, the effects of fly ash on the ecological factors of shajiang black soil in winter wheat field were studied through barreled experiments. The results showed that the application of flyash into lime black soil reduced the bulk density, specific gravity and clay content of soil, increased the total porosity, capillary porosity and saturated hydraulic conductivity of soil. The simulation equations of soil bulk density, specific gravity, capillary porosity, saturated hydraulic conductivity and fly ash content were obtained respectively. At the same time, the dynamic changes of soil temperature, soil water content and soil microbial population during the whole growth period were also studied.
