酿酒葡萄种植区土壤剖面调查分析

Analysis of Soil Profile in Wine Grape Growing Area

贺兰山东麓酿酒葡萄产区土壤贫瘠结构差,为了确保该地区的酿酒葡萄可持续生产,该研究采用随机取样的方式调查了葡萄耕作层土壤的理化性质,结果表明:研究区土层深厚,土壤通透性较好,有一定的养分积累,地形相对平坦,孔隙性好,通气透水性强。上部为紧实的钙积层,容重较大,不利于作物扎根,下层大多数为洪积砂砾层,漏水漏肥严重。土壤整体有机质含量低,营养元素含量低,pH强碱性,均不利于作物的高产、稳产,需要重点改良培肥。

Helan mountain wine grape production areas soil was poor and the structure was poor, in order to ensure sustainable wine grape production in the region, with the method of random sampling investigation of grape magnetism of soil physical and chemical properties. The results showed that ： the soil deepth and soil permeability in the study area was good, which had certain nutrients accumulation, relatively flat terrain, good porosity, and strong air permeability. Upper was compacted calcium deposition layer, bulk density was bigger that not conducive to root crops, mostly diluvial gravel layer, lower fat leaking seriously. Soil organic matter content as a whole was low, low content of nutrient elements, pH strongly basic, crops were not conducive to high and stable yield, it was important to improve fertilizer.
