| 摘 要： | 目的]调查蓬莱市酿酒葡萄园的肥力状况。方法]在山东蓬莱市某酿酒公司的葡萄园中设置21个采样点,涵盖种植2～5年的不同质地土壤,每个采样点分0～20、20～40 cm土层取土测定土壤速效氮磷钾、有机质、pH、容重。结果]不同质地的土壤肥力从大到小依次为黏土、壤土、砂土。0～20 cm土层中的速效氮磷钾和有机质含量明显高于20～40 cm土层中的含量,速效氮磷钾和有机质含量随土壤深度的加深呈递减趋势。结论]种植年限越长,土壤中积累的速效氮磷钾和有机质含量越高,而土壤pH降低。土壤pH和土壤中速效氮的含量呈负相关。 |

| Abstract: | Objective]The aim was to survey soil fertility of wine-grape orchard in Penglai City.Method]21 sampling points were set in vineyards located in Penglai City,covering different soil types of 2-5 years cropping,and samples of 0-20,20-40 cm soil layer depth were collected.Available nitrogen,phosphorus,potassium,organic matters,pH and bulk density of the samples were measured.Result]The fertility of the different soil types rank order(from big to small) was slime,loam and sandy soil.Available nitrogen,phosphorus and potassium in 0-20 cm layer existed more than that of 20-40 cm.Furthermore,the contents of available nitrogen,phosphorus,potassium,and organic matters decreased with the increase of soil depth.Conclusion]The longer the soil was cultivated,the more available nitrogen,phosphorus,potassium,and organic matters were accumulated.Because large amount of fertilizer was applied in the vineyards each year,pH of the soil decreased with the increase of cropping time.Negative correlation was existed between soil pH and available nitrogen,phosphorus and potassium. |
