摘要
大田试验条件下研究了酸性土壤改良剂对蛇龙珠葡萄园酸性土壤的改良作用及其对葡萄与葡萄酒品质的影响。以钾长石和白云石煅烧粉末为土壤改良剂,于葡萄萌芽前分别以0、4500和9000 kg/hm^(2)的用量对葡萄园土壤进行改良处理。结果表明:与对照相比,随着土壤改良剂用量的增加,不同土层土壤pH、电导率呈增加的趋势,高剂量土壤改良剂使0~20、20~40 cm土层土壤交换性K、Ca和Mg等矿质元素的含量增加23.8%~102.7%。土壤改良剂处理对葡萄生长指标无显著影响。与对照相比,两种用量土壤改良剂处理使葡萄果实成熟度(糖酸比)显著增加10.7%、9.4%。此外,高剂量土壤改良剂处理使葡萄酒中总酚、单宁、黄酮等酚类物质含量显著提高16.8%、10.4%、7.1%。酿酒葡萄园施用酸性土壤改良剂可有效改良酸性土壤且提高果实成熟度和葡萄酒的品质。
Field experiment was conducted in Yantai wine region to explore the effect of chemical soil amendment on acidic soil,vine growth and the quality of grape and wine.Three levels(0,4500 and 9000 kg/hm^(2))of soil amendment,from calcined dolomite and potash feldspar in powder,were applied in Cabernet Gernischt vineyard.The result showed that with the increase of soil amendment,soil pH was increased,as well as soil electric conductivity,and the contents of K,Ca and Mg in the 0~20,20~40 cm soil layer were increased by 23.8%~102.7%,with high dosage of soil amendment.Soil amendment treatments had no effect on vine growth,while the treatments increased grape maturity by 10.7%and 9.4%,compared with the control.The contents of phenolic compounds and tannins of wine were elevated significantly by 16.8%,10.4%,7.1%,respectively,with high dosage of soil amendment.The results indicated that the treatment of chemical soil amendment could effectively ameliorate acid soil,and improve fruit maturity and wine quality.
