【摘要】：为提高农田人参产出量,通过田间定位施用畜禽粪肥,研究黑土增施猪粪、鹿粪、鸡粪、牛粪180 d后对农田栽参土壤养分和腐殖物质组成的影响。研究结果表明,黑土施入畜禽粪肥后,土壤全氮、全磷、速效钾含量分别较对照提高114.47%~185.53%、38.36%~180.82%、28.30%~347.35%;土壤有机碳、可提取腐殖物质分别增加20.43%~80.34%、20.06%~80.32%;可提取腐殖物质的色调系数、E465/E665比值均较对照提高。与对照比较,牛粪处理土壤有机碳、胡敏酸、富里酸、胡敏素分别增加了80.32%、46.23%、116.58%、113.95%,猪粪处理土壤中碱解氮、有效磷、速效钾分别增加了100.34%、429.25%、347.35%。畜禽粪肥的添加为农田栽参土壤补充了养分,促进了腐殖物质的形成,增强了腐殖物质的活性和有效性,施入牛粪对于土壤有机碳增加和腐殖物质形成的贡献最大,而猪粪能全面为植物提供氮、磷、钾养分。
[Abstract]:In order to increase the yield of ginseng in farmland, the effects of adding pig manure, deer dung, chicken manure and cow dung on soil nutrients and humus composition of cultivated ginseng were studied by applying livestock manure in the field. The results showed that the contents of total nitrogen, total phosphorus and available potassium increased 114.47 and 185.53 respectively after the application of manure to the black soil, and the contents of total nitrogen, total phosphorus and available potassium in the soil were increased by 38.36% ~ 180.82% and 28.30% ~ 347.35%, respectively, compared with the control. Soil organic carbon can be extracted from humus by 20.43% and 20.06%, respectively. The hue coefficient and E465/E665 ratio of extracted humic substances are higher than that of the control. Compared with the control, the soil organic carbon, Hu Min acid, fulvic acid and humin in cattle dung treatment were increased by 80.32 ~ 46.23 and 113.95%, respectively, and alkali-hydrolyzed nitrogen and available phosphorus were treated with pig manure, respectively. The available potassium increased by 100.34 and 429.25, respectively. The addition of livestock manure supplemented soil nutrients, promoted the formation of humic substances, enhanced the activity and effectiveness of humic substances, and contributed the most to the increase of soil organic carbon and the formation of humic substances. Pig manure can provide nitrogen, phosphorus and potassium nutrients for plants.
