为探讨沿海涂地设施葡萄土壤养分状况及其对果实品质的影响,以温岭市设施葡萄集中产地的13个葡萄园为对象,对土壤养分、pH值现状、覆膜前后的变化及与果实品质的关系进行了研究.结果表明,本市沿海设施葡萄园土壤pH6.6~8.2,呈弱碱性土,有机质、含盐量和碱解氮含量一般,分别为22.05 g/kg、0.8 g/kg和122.23 mg/kg,有效磷和速效钾达到108.52 mg/kg和753.38 mg/kg,含量十分丰富;覆膜后,土壤有机质、氮、磷、钾水平变化不大,但69.2%的园地土壤出现酸化,土壤含盐量也提高85.6%;pH值与单果质量间极显著正相关,有机质和有效磷与单果质量达显著负相关水平,其他元素与果实品质间无显著相关性.试验表明,我市葡萄园土壤养分状况整体较为适合葡萄生长,但覆膜后存在明显土壤酸化和盐碱化问题,且能影响果实品质,需合理施肥进行土壤改良.

To find out the main soil nutrient status and its effects on the fruit quality of grape protected cultivation in coastal land, the current status of soil nutrients, pH value and the changes fore-and-aft film mulching, as well as its correlation with fruit quality were studied in 13 vineyards of Wenling city. The results showed that the soils of the 13 vineyards were mainly weakly alkaline, with pH value ranging from 6.6 to 8.2. The organic matter, salinity and alkali-hydrolyzable nitrogen were 22.05 g/kg, 0.8 g/kg and 122.23 mg/kg in general, while available phosphorus and available potassium richly reached 108.52 mg/kg and 753.38 mg/kg. After film mulching, the level of soil nutrients such as organic matter, nitrogen, phosphorus and potassium were slightly different, but 69.2 percent of soils were more acidic with a 85.6 percent promotion in soil salinity. The fruit weight was significant positively correlated with pH value, but negatively correlated with organic matter and available phosphorus. In addition, the other soil elements hadn't significant correlation with fruit quality. The studies suggested that the soil nutrient status in these vineyards were suitable for grapevine growth on the whole, whereas an obvious soil acidification and salinization problem appeared after film mulching, which could affect fruit quality. So scientific and rational fertilization were required for soil improvement.
