【摘要】：为了研究煤基固废与牲畜粪便混合固态发酵基质作为沙土肥料的特性,采用随机区组试验设计,将地质肥料与沙土混合并栽种植物,测定不同施肥处理的物理、化学、生物肥力指标和生产力水平共17个指标,应用方差分析和主成分分析等方法综合分析评价了不同施肥处理的肥力因子以及生产力水平,并对不同施肥处理的培肥效果进行了综合评定。结果表明:与沙土对照相比,不同地质肥料对土壤肥力因子的影响差异显著(P0.05),能源草的总生物量增加了246.3%~566.4%,土壤容重下降了4.4%~9.5%,土壤速效钾、速效磷和氨氮分别增加了282.4.4%~424.7%、157.2%~296.2%和70.3%~288.0%。通过主成分分析综合评分显示,施用地质肥料处理得分值明显高于施用粪肥处理和未施肥处理对照,同时配施微生物菌剂的处理得分高于未配施微生物菌剂的处理。施用含30%煤基固废的地质肥料,同时配施微生物菌剂,可最大限度的改善沙土的理化特性,显著提高沙土的肥力。
[Abstract]:In order to study the characteristics of mixed solid-state fermentation medium of coal based solid waste and livestock manure as sandy soil fertilizer, the geological fertilizer and sand soil were mixed and planted plants were mixed by random block experiment design, and the physical and chemical properties of different fertilization treatments were determined. There were 17 indexes of biological fertility and productivity. The fertility factors and productivity levels of different fertilization treatments were comprehensively analyzed and evaluated by means of variance analysis and principal component analysis. The effects of different fertilization treatments on fertilization were comprehensively evaluated. The results showed that: compared with the control of sandy soil, The effects of different geological fertilizers on soil fertility factors were significantly different (P 0.05), the total biomass of energy grasses increased by 246.3 and 566.4, the bulk density of soil decreased by 4.4% and 9.5%, and the available potassium, available phosphorus and ammonia nitrogen increased by 282.4.4N 424.70.The total biomass of energy grasses increased by 282.4.42296.2% and 70.3N 288.0.The results of principal component analysis showed that. The scores of geological fertilizer treatment were significantly higher than those of manure treatment and non-fertilizer treatment, and the scores of treatment with microbial bacteria were higher than those with no microbial bacterial agent, and the application of geological fertilizer containing 30% coal based solid waste was better than that of non-application of microbial bacterial agent. At the same time, the physical and chemical properties of sandy soil can be greatly improved and the fertility of sandy soil can be significantly improved by applying microbial bacteria.
