摘要: 本试验从植被-土壤-微生物角度评价有机肥单施和有机肥混施对退化天然割草地的恢复效果,研究以阿尔泰山天然割草地为对象,采用单施有机肥(M),混施有机肥和生物菌肥(M+NY)、混施有机肥和复合肥(M+NPK)三个施肥措施,探究草地植被-土壤-微生物对施肥的响应。结果表明:施肥显著增加了草地群落高度、生物量、土壤有机质含量、速效氮、速效磷、速效钾含量和电导率(P<0.05),显著降低土壤pH值(P<0.05);土壤细菌中5个门类丰富度变化差异显著(P<0.05),土壤真菌中2个门类丰富度变化差异显著(P<0.05);灰色系统关联度显示,复合肥+有机肥促进植被生长、改良土壤养分以及增加微生物数量效果最好,对补播天然割草地植被-土壤-微生物系统起到快速恢复作用。试验结果为有机肥单施和有机肥与其他肥料混施在补播天然割草地生产和恢复作用提供了理论依据、数据支持以及技术支撑。

Abstract: In this experiment, the effects of single application of organic fertilizer and mixed application of organic fertilizer on the restoration of degraded natural mowing land were evaluated from the perspective of vegetation-soil-microorganism. The natural mowing land in Altay Mountains was used as the object of study. Three fertilization measures, single application of organic fertilizer (M), mixed application of organic fertilizer and biological fertilizer (M+NY), mixed application of organic fertilizer and compound fertilizer (M+NPK), were used to explore the responses of grassland vegetation-soil-microorganism to fertilization. The results showed that fertilization significantly increased grassland community height, biomass, soil organic matter content, available nitrogen, available phosphorus, available potassium content and electrical conductivity (P<0.05), and significantly reduced soil pH value (P<0.05). There were significant differences in the richness of 5 phyla in soil bacteria (P<0.05), and there were significant differences in the richness of 2 phyla in soil fungi (P<0.05). The grey system correlation degree showed that compound fertilizer + organic fertilizer had the best effect on promoting vegetation growth, improving soil nutrients and increasing the number of microorganisms, and had a rapid recovery effect on the vegetation-soil-microbial system of reseeding natural mowing land. The results of the experiment provide theoretical basis, data support and technical support for the production and restoration of organic fertilizer single application and organic fertilizer mixed with other fertilizers in reseeding natural mowing land.
