【摘要】 通过对山西省寿阳县褐土旱地15年长期定位施肥试验,结果表明,有机无机配合施肥及单施有机肥都能显著增加0～40 cm土壤全磷、有机磷和速效磷的含量,单施化肥能够提高0～20 cm土壤全磷、有机磷和速效磷含量。长期施肥主要增加了0～20 cm土壤全磷、有机磷和速效磷含量。土壤磷素层间分布随不同的有机无机配合施肥发生变化。更多还原

【Abstract】 The results of 15 years experiment of long-term fertilization in cinnamon soil upland showed that the contents of total phosphorus,organic phosphorus and rapidly available phosphorus were improved significantly in 0～40 cm soil under the methods of combined application of organic fertilizer and inorganic fertilizer and using organic fertilizer only.Applying inorganic fertilizer for long term increased contents of soil total phosphorus,organic phosphorus and rapidly available phosphorus in 0～20 cm soil.Long-term fertilizer mainly increased contents of total phosphorus,organic phosphorus and rapidly available phosphorus in 0～20 cm soil.And the layer distribution of phosphorus was changed with the different methods of fertilizer application.更多还原
