- 摘要:
- 为研究不同培肥处理对平朔露天煤矿复垦土壤作物养分含量及肥料利用率的影响，进行了玉米盆栽试验，结果表明：不同培肥处理对玉米植株的N，P，K含量均有提高作用，玉米N，P，K在根、茎、叶器官分配顺序为叶 > 茎 > 根；有机肥、菌肥和配施低浓度化肥处理对玉米N素含量增加最明显，有机肥、菌肥和化肥配施各处理对玉米P和K含量增加最明显，其次对玉米N，P，K含量增加较明显的为有机肥配施菌肥处理，而单施有机肥处理对玉米N，P，K含量增加效果最差；有机肥、菌肥和化肥配施处理对玉米N，P，K肥利用率高于有机肥配施菌肥处理更高于单施有机肥处理，此研究为恢复矿区复垦土壤肥力水平提供理论依据。
- Abstract:
- We studied the impact of different fertilizing treatments on crop nutrient content and fertilizer use efficiency of reclaimed soil at Pingshuo open mine area by conducting maize pot experiment. The results were summarized as follows. All of the different fertilizing treatments improved the N, P and K contents of maize, and the distribution order of N, P and K in maize was leaf > sti > root; organic manure and bacterial fertilizer combining with low concentration of chemical fertilizer improved N content of maize most obviously. Organic manure and bacterial fertilizer combing with chemical fertilizer improved P and K contents of maize most obviously. Organic fertilizer combing with bacteria fertilizer improved N,P and K contents of maize relative obviously. However, the effect of applying organic manure on improving N,P and K contents of maize was the worst. Combination of organic fertilizer, bacteria fertilizer and chemical fertilizer had the higher efficiency compared with using organic manure. This study could provides theoretical basis for the restoration of soil fertility of reclaimed soil in the mining areas.
