    摘要:

    在小麦、玉米复种轮作制中,合理施肥是决定作物产量和提高土壤肥力的重要因素之一.有关翻压绿肥、秸秆还田的方法及增产效果已有很多报道,但对豆科绿肥、禾本科秸秆配合施用,改善土壤结构性状,恢复与保持腐殖质含量水平的研究较少.因此,研究绿肥、麦秸还田的增产作用和培肥效果,具有重要意义.

    Abstract:

    The effect of turnover of farm-manure,green-manure,wheat straw and mixed application of 1/2 green-manure and 1/2 wheat straw into soil on soil fertility in the rotation of winter wheat and corn in Shangdong Province was studied.Experiment showed that these manuring measures not only increased total amount of organic matter,but also improved its quality,and the stability of aggregates and nutrient condition in the soil.For the aggregates in diameter from 0.25mm to 3.0 mm,the total content of organic matter increased with the increase in size of aggregates.The proportion of Gl fraction of the complexes tended to increase,while the proportion of G2 fraction tended to decrease with the increase in size of aggregates.The G1/G2 ratio was getting increased with the increase in size of aggregates.
