| 摘 要： | 探讨了硫磺粉、硫酸亚铁和糠醛渣 3种物质对石灰性褐土上小麦产量及其地上部吸磷量的影响。结果表明 ,单施酸性物质或与氮磷肥配合施用均可提高小麦产量及其地上部吸磷量 ,增产幅度可达 6 2 %～ 12 0 % ,吸磷量可增加 3 7%～ 2 7 7% ,其中硫酸亚铁与氮磷肥配合施用的增产效果最好 ,单施硫酸亚铁的处理次之。施用酸性物质代替部分磷肥可在一定程度上降低肥料投入

| Abstract: | The study on effect of three acid materials S,FeSO 4,and the waste residue of producing Kangquan on the phosphorous adsorbing ability and yield of wheat was conducted.The results showed that both applying acid material only and applying them with N and P can increase yield of wheat and phosphorous adsorbing ability.The wheat yield could be increased by 6 2%-12 0%,and the amount of phosphorous adsorbing increased by 3 7%-27 7%.The effect of applying FeSO 4 with N and P was the best,followed by applying FeSO 4 only.Acid materials replace a part of phosphorus can decrease fertilizer cost to a certain extent. |
