黑土长期定位试验原状土搬迁对土壤腐殖质组分数量及光学特性的影响
Study on the Change of Humus Contents in Black Soil Under the Soil Removal on Long-term Fertilization Experimental Field
摘要
Abstract
The change of the humus compositions and optical property of humus in black soil under the soil re‐moval were studied on the basis of the soil removal of long‐term located experiment field .The results indicated that the content of HE and FA was first increased and then decreased ,soil change ratio in 20~40 cm layer was higher than it in 0~20 cm layer soil ,the change rate of manure + chemical treatment and manure treatment were higher .The influence of HA under removal had no significant difference in the two layers .The ratio of HA to FA decreased in the first year after removal and increased in the second year ,the influence in two layers had no obvious difference .The content of HM had no obvious difference after removal ,it still increased year by year .The △log K and E4/E6 of HE and FA had increased after removal and decreased in the second year after removal .The △log K and E4/E6 of HA had no obvious variation after removal .The change of optical proper‐ties in the various components had no obvious regularity between two different layers .关键词
