宁夏不同压砂地龄土壤养分对西砂瓜品质的影响

Effect of Soil Nutrients of Different Age Grave-covered Field on Quality of Water-melon in Ningxia

以西砂瓜为试材,选择宁夏西砂瓜主产区环香山地区为研究区域,通过对主产区不同压砂地龄(新砂田、中砂田、老砂田)土壤养分含量的检测及对影响西砂瓜品质的主要生理指标进行检测,综合分析不同压砂地龄对宁夏西砂瓜品质的影响及其相关性,为解决宁夏西砂瓜产业持续发展提供参考依据。结果表明:环香山地区种植的西砂瓜糖度分布均匀,新砂田种植出的西砂瓜品质相对优于中砂田和老砂田。通过对不同砂田地龄土壤养分的检测分析发现,土壤养分比值均衡与西砂瓜品质呈正相关;土壤全盐含量过高、有效养分含量过低均能导致西砂瓜品质下降。

Taking water-melon as test material,the main water-melon producing area,namely,the Huanxiangshan area in Ningxia was selected as the research area,the soil nutrient contents of different age grave-covered fields（new grave-covered field,middle age grave-covered field,old grave-covered field）in the main producing area and the main physiological indexes affecting the quality of the water-melon were detected,and the effects and the relevance of different ages of the grave-covered fields on the quality of the water-melon in Ningxia were analyzed comprehensively to provide reference for the sustainable development of the water-melon industry in Ningxia.The results showed that the distribution of the sugar degree of the water-melon produced in the Huanxiangshan area was uniform and the quality of the water-melon produced on the new grave-covered field was relatively better than those of the water-melon produced on the middle age grave-covered field and the old grave-covered field.It was found by detection and analysis of the soil nutrient contents of different age grave-covered fields that there was a positive correlation between the ratio balances of the soil nutrients and the quality of the water-melon.Higher a soil total salt content was one of the causes which causing the decline of the water-melon quality.Also lower a soil effective nutrient content was one of the causes which causing the decline of the water-melon quality.
