济南市葡萄园土壤肥力水平分析及施肥建议

Soil Fertility Status and Fertilization Recommendation for Vineyards in Jinan City

为了解济南市葡萄园的土壤养分状况,试验采集了济南市历城、长清、章丘、济阳、平阴、商河6个地区20个葡萄园的土壤样品,通过分析pH、有机质、速效N、P、K、Ca、Mg、Fe、Mn、Cu、Zn、B等土壤养分指标,得到了济南市不同地区葡萄园土壤养分状况,分析了济南市葡萄园的土壤肥力。结果发现,济南市葡萄园土壤为碱性,土壤有效养分大部分集中在表层土中(0~20 cm);葡萄园表层土壤(0~20 cm)的大量元素(水解性N、有效P、速效K)平均含量较高,且高水平园区比例大;土壤交换性钙含量较高,微量元素中土壤有效铁和有效硼含量较低,呈缺乏水平;土壤有效锰和有效锌含量为中等水平;土壤有效铜含量为较高水平。针对分析结果提出了济南地区葡萄园的施肥建议。

To comprehend the vineyard soil fertility status in Jina ns’main grapevine growing areas,this paper had collected 20 vineyard soil samples from 6 counties and districts in Licheng distric,Changqing distric,Zhangqiu distric,Jiyang distric,Pingyin county and Shanghe county of Jinan city,and analyzed the p H,organic matter,readily available N,P,K,Ca,Mg,Fe,Mn,Cu,Zn,B and other indexes of soil nutrient content,to obtain the soil nutrient status of vineyards in different areas of Jinan city.The results showed that the vineyard soil in Jinan was alkaline,and most of the available nutrients were concentrated in the topsoil(0-20 cm).The average content of a large number of elements(hydrolytic N,available P,available K)in the surface soil(0-20 cm)of vineyard was high,and the proportion of high-level vineyard was large.The content of exchangeable Ca in soil was high,the content of available Fe and available B in soil was low,showing a lack level;the content of available Mn and available Zn in soil was medium;the content of available Cu in soil was high.On this basis,the soil nutrient status of vineyards in Jinan city was summarized and analyzed.According to the current situation of soil fertility in the vineyards of Jinan city,some suggestions for fertilization were put forward.
