摘要
[目的] 研究食用醋在蓝莓生产中的应用规律.[方法]以4年生"灿烂"兔眼蓝莓为对象,采用盆栽试验,以硫磺和硫酸钾为对照,研究不同浓度醋酸处理对蓝莓生长势及叶片全N、全P及全K含量的影响.[结果]每10kg基质施用35 mL食用醋蓝莓植株长势最好.施用硫磺和不同浓度的食用醋都能在5月将土壤pH降低至蓝莓生长发育最适的4.0~4.8范围,在最适范围内,蓝莓叶片N、P及K含量的差异不显著;硫酸钾调节土壤pH的效果不理想,在整个检测周期土壤pH均高于4.8,而相应处理蓝莓叶片的N、P及K含量也较低.同时,蓝莓叶片N、P及K的含量随不同的物候期呈一定的变化规律,即先下降(5-7月)后上升(8-9月)再降低(10月)趋势.[结论] 该研究可为蓝莓土壤改良、营养诊断及科学施肥提供参考依据.
Abstract
[Objective] Application regularity of vinegar for blueberry was studied.[Method] Taking 4-year-old blueberry Canlan as test material,pot experiment was carried out to analyze growth potential and total nitrogen,phosphorus and potassium content in leaves of 4-year-old blueberry by application of different concentration of vinegar,with sulphur and potassium sulphate as comparison.[Result] Growth potential was the best by application of 35 mL vinegar per 10kg soil.The soil pH value decreased to 4.0-4.8 in May by application of sulphur and different levels of vinegar,which was the most proper pH value for blueberry.In this range,the nitrogen,phosphorus and potassium content in leaves had no significant difference.The application of potassium sulphate was not well with pH value above 4.8,while the nitrogen,phosphorus and potassium content was lower.The nitrogen,phosphorus and potassium content in leaves were regular in a certain degree with phenological phase,that dropped in first(May to July),increased (August to September)and then decreased again(October).[Conclusion] The research could provide a basis for soil improvement,nutritional diagnosis and fertilization.
