    摘要:

    本文根据13年的定位研究资料,较系统的阐述了不同量有机肥与氮、磷化肥配合施用,及关中灌区两熟制粮食产量、土壤肥力和养分平衡的影响.初步揭示了关中楼土的基本生产力持续时间较短;土壤的供肥能力是玉米高于小麦.作者认为采用有机肥与氮、磷化肥配施,才是该区粮田持续高产和土壤培肥的有效措施.

    Abstract:

    Effects of combined application of organic manure and chemical fertilizers on crop yields,Soil fertility and nutrient balance were studied systematically according to the results of a 13-year located experiment.The results show that the basic productivity of lou soil in Guanzong could be kept in a shorter period of time.The amounts of soil nutrients supplied for corn were higher than those for wheat.So,the application of N and P in combination with organic manure would be an efficient way for raising crop fields and soil fertility in irrigated area.
