摘　　要：试验对山西省大同和运城2个地区的养殖池塘底泥产量进行了测定,并对比了底泥和池塘周边土壤中营养盐的含量,最后用底泥和池塘周边土壤进行了菠菜生产力的研究。结果表明,大同和运城2个地区养殖池塘底泥沉积量分别为19.18和19.98 kg/m2,二者相差不大但产量均较大。对底泥与池塘周边土壤中营养盐的研究表明,池塘底泥中的营养盐明显高于池塘周边土壤,种植菠菜后试样中各营养盐含量明显降低。试验组与对照组的菠菜生产力虽高于池塘周边土壤组,但差异不大,可见池塘周边土壤也可以直接用于植物种植,试验组与对照组底泥可用于对低肥力土壤的改良。The yield of bottom bud in culture pond in Datong and Yuncheng of Shanxi Province was measured. And the contents of nutrient salt in the bottom bud and its surrounding soil were compared. Finally the productivity of Spinacia oleracea L. in bottom bud and its surrounding soil was studied. The results showed that the sediment amounts of bottom bud in the ponds of Datong and Yuncheng were 19.18 and 19.98 kg/m2 respectively. They were both higher, but there was little difference. The results of nutrient salt in the bottom mud and its surrounding soil of pond showed that the content of nutrient salt in the bottom mud of pond was obviously higher than that in the surrounding soil of pond. And the content of nutrient salts in test materials obviously decreased after planting S. oleracea. The productivity of S. oleracea in test group and control group were higher than that in the surrounding soil of pond, but there was little difference. Therefore the surrounding soil of pond could also be used for planting and the bottom mud in test group and control group could be used in the improvement of low-fertility soil.
