摘要
试验结果表明,白浆土上施有机肥,连作大豆产量显著高于施化肥,而施化肥高于秸秆还田和不施肥处理。有机肥和化肥可保持土壤有效磷含量,长期施入土壤中的磷素向Al-P和Fe-P形态转变。
The research showed that the yield of soybean successive planting with application organic fertilizer was significant higher than that with application chemical fertilizer in Ablic soils, and that with application chemical fertilizer was higher than crop straw ploughing under and no fertilization. The content of available phosphorus was maintained by organic and chemical fertilizer. Phosphorus were translated to Al-P and Fe-P in long-term application phosphorus soil.
