摘 要:通过田间小区试验,探讨了化肥、有机肥、石灰石粉、结构改良剂配合施用对新垦红壤性状综合改良的效果以及对大豆产量的影响。试验结果表明:与对照相比,对土壤质量综合提升和大豆生长效果最佳的处理为石灰石粉+化肥-有机肥配合施用+结构改良剂,其次为石灰石粉+化肥-有机肥配合施用;化肥-有机肥配合施用的效果好于单施化肥或单施有机肥的效果;石灰石粉+单施有机肥处理的改土效果好于石灰石粉+化肥处理的效果,但对作物生长的效果略差于石灰石粉+化肥处理的效果。The comprehensive effects of chemical fertilizer,organic fertilizer,limestone and structural modifier on the improvement of newly cultivated red soil and soybean yield were discussed by the plot field experiment.The results showed that the best treatment for improving soil quality and soybean growth was limestone+chemical fertilizer+organic fertilizer+structural modifier,followed by limestone+chemical fertilizer+organic fertilizer.The effect of chemical fertilizer+organic fertilizer combined application was better than that of chemical fertilizer alone or organic fertilizer alone.The effect of limestone+organic fertilizer was better than that of limestone+chemical fertilizer,but the effect of limestone+organic fertilizer on crop growth was slightly weaker than limestone+fertilizer.
