摘　　要：[目的]揭示梯度堆肥添加对黑土理化性质的影响。[方法]以黑农35作为供试大豆品种,采用完全随机区组设计,共设4个处理,分别为堆肥添加量1.5、3.0、6.0 kg/m^2,以不添加堆肥作为对照,研究不同堆肥添加量对土壤含水量、p H、总氮(TN)、总磷(TP)、有机质、速效磷、速效钾含量以及大豆产量的影响。[结果]大豆的不同生长发育期及梯度堆肥添加均可提高土壤有机质、TN、TP、速效磷和速效钾的含量以及大豆产量。其中,1.5和3.0 kg/m^2的堆肥投入量对有机质、TN、TP、速效磷、速效钾含量较对照均有一定的提升,但并未达到显著水平,而堆肥投入量为6.0 kg/m^2时,对土壤理化性质的改善最为显著。[结论]松嫩平原大豆生产中推荐堆肥添加量为6.0 kg/m^2。[Objective] To reveal the effects of gradient compost addition on the physical and chemical properties of black soil.[Method]With Heinong 35 as the tested soybean variety, we adopted the completely randomized block design .There were in all four treatments,which were 1.5, 3.0 and 6.0 kg/m^2 compost treatments and no compost treatment .Effects of compost dosage on soil moisture content, pH,total nitrogen, total phosphorus, organic matter , available phosphorus and available potassium were researched.[ Result] Gradient compost enhanced the soil organic matter, total nitrogen, total phosphorus, available phosphorus, available potassium and soybean yield during all growth stages.Among them, 1.5 and 3.0 kg/m^2 compost input increased the organic matter, total nitrogen, total phosphorus, available phosphorus and available potassium in certain degrees, but did not reach significant level.However, 6.0 kg/m^2 compost was the most significant in improving soil physical and chemical properties.[Conclusion] The 6.0 kg/m^2 compost is recommended in soybean production in Songnen Plain.
