本文总结了青浦县朱家角乡青紫泥类型湖积草甸土长期定位试验1979~1988年的10年间不同施肥处理区,农作物产量、土壤主要物理性质、土壤化学性质、土壤生物性质、土壤养分平衡等指标的变化,分项讨论了集约化多熟制种植条件下无肥区、有机肥区、化肥区、有机肥化肥区等不同肥料管理对土壤肥力的影响。结果表明,施用有机肥不仅为作物提供大量可给态养分,而且对土壤肥力的增生有明显的作用,但并不是无限的。采用有机肥化肥配合施用,是建立高产稳产农田一项重要管理措施。
This paper summarizes the different fertilization treatment areas, crop yields, main physical properties of soils, soil chemical properties, soil biological properties, soil nutrient balance and so on during the long-term positioning experiment of Qingzijia type lacustrine meadow in Zhujiajiao Township, Qingpu County, 1979-1988 This paper discusses the effects of different fertilizer management such as no fertilizer zone, organic fertilizer zone, chemical fertilizer zone and organic fertilizer zone on soil fertility under the intensive multi-cropping system. The results show that the application of organic fertilizer not only provides crops with a large amount of available nutrients, but also has obvious effects on the fertility of soil fertility, but it is not limitless. The use of organic fertilizer with the application of fertilizer is to establish high and stable yield farmland is an important management measure.
