| 摘 要： | 采用桶栽试验，研究粉煤灰改良砂姜黑土对冬小麦田生态因子的影响。研究结果表明：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，井得出土壤容重、比重、毛管孔隙度和饱和导水率与粉煤灰用量的模拟方程。与此同时，还对土壤温 度、土壤含水量及土壤微生物数量在整个生育期的变化动态进行了研究。

| Abstract: | Effect of Shajiang Black soil amended by fly ash on winter wheat ecological factors was studied by use of barrel cultivated experiment.The result showed that fly ash applied in Shajiang black soil could decrease soil density,soil proportion and clay particle content and increase soil total porosity, capillary porosity and coefficient of soil saturation conductive water.The simulation equations between these ecological factors and the amount of fly ash were gained.In the same time, changing situations of soil temperature,soil water content, the number of soil microorganism in developing process of wheat were studied. |
