摘要

需要研究氮含量相同的不同肥料类型对玉米根系形态和土壤可利用养分的影响，尤其是在煤矿复垦区。施肥 9 年后，有机-无机肥料（OF）处理的玉米根生物量、长度和表面积显著高于其他处理。有机-无机肥料处理的可利用磷和可利用钾含量分别为 18.46 和 176 mg-kg-1，明显高于其他处理。我们的研究结果表明，OF 处理的肥效对矿区土壤改良是有效的。

Responses of maize root morphology and soil available nutrient to fertilizer types in a coal mine reclamation area

The impact of different fertilizer types with equal nitrogen levels on maize root morphology and soil available nutrient is needed, especially in coal mine reclamation areas. After 9-year fertilization, the maize root biomass, length, and surface area of the organic–inorganic fertilization (OF) treatment were significantly higher than those of other treatments. The contents of available phosphorus and available potassium were 18.46 and 176 mg·kg−1, respectively, under OF treatment, which were significantly higher than those under other treatments. Our findings indicate that the fertilizing effect of OF treatment is effective for soil reclamation in mining areas.

期刊介绍： The Canadian Journal of Soil Science is an international peer-reviewed journal published in cooperation with the Canadian Society of Soil Science. The journal publishes original research on the use, management, structure and development of soils and draws from the disciplines of soil science, agrometeorology, ecology, agricultural engineering, environmental science, hydrology, forestry, geology, geography and climatology. Research is published in a number of topic sections including: agrometeorology; ecology, biological processes and plant interactions; composition and chemical processes; physical processes and interfaces; genesis, landscape processes and relationships; contamination and environmental stewardship; and management for agricultural, forestry and urban uses.
