选用三大类８种有机物料，进行盆栽试验。结果表明，Ｃ／Ｐ小、含Ｐ量高的绿肥、粪肥能明显增加土壤中无机磷和有机磷的有效形态，而Ｃ／Ｐ大、含Ｐ量低的秸秆类物料则增加不明显。播前培养一个月、小麦秸处理磷的生物固定大于矿化；绿豆秸处理磷的矿化大于生物固定；猪粪处理的二者基本平衡。以粪肥、绿肥类物料作为磷源能明显地增加小麦生物学产量，而秸秆类物料非但不增产，有的还有一定程度减产。
Choose three kinds of eight kinds of organic materials, pot experiments. The results showed that the green manure and manure with small C / P and high P content could obviously increase the effective forms of inorganic phosphorus and organic phosphorus in the soil, while the straw material with large C / P and low P content did not increase obviously. One month before sowing, the biological fixation of phosphorus in wheat straw was greater than that in mineralization; the mineralization of phosphorus in mung bean straw was more than that in biological fixation; the balance between pig manure and pig manure was basically balanced. The use of manure and green manure as phosphorus source can significantly increase the biological yield of wheat, while the straw material not only does not increase production, but also reduces production to some extent.
