摘要: 北方农田土壤质量退化问题突出,制约着现代农业可持续发展。本研究基于北方冬小麦-夏玉米种植区,选用生物炭、腐植酸、硅钙材料和明矾等作为土壤调理剂,开展了T1(对照)、T2(腐植酸)、T3(生物炭)、T4(明矾)、T5(硅钙材料)、T6(生物炭+明矾)、T7(腐植酸+生物炭+明矾)等7个处理的三茬定位试验。结果表明:生物炭处理对夏玉米的增产和氮磷钾养分吸收效果最好,其次是生物炭+明矾处理。从经济效益来看,前期T2和T5处理较好,后期T3和T6处理表现良好。综合作物产量、养分吸收和经济效益情况,T3(生物炭)和T6(生物炭+明矾)两处理效果较明显。

Abstract: The problem of soil quality degradation in northern farmland was prominent, which restricted the sustainable development of modern agriculture. This experiment proposed to use humic acid, biochar, alum and silicon calcium materials as soil conditioner materials in the northern winter wheat-summer corn planting area, and designed T1(control), T2(humic acid), T3(biochar), T4(alum), T5(silicon calcium material), T6(biochar+alum), T7(humic acid+biochar+alum)7 treatments positioning test in three planting season crops. The results showed that biochar treatment had the best effect on summer maize yield increase and nitrogen, phosphorus and potassium nutrient uptake, followed by biochar+alum treatment. From the perspective of economic benefits, the early T2 and T5 treatments were better, and the late T3 and T6 treatments performed well. Comprehensive considering crop yield, nutrient uptake and economic benefits, T3(biochar)and T6(biochar+alum)were more effective.
