蓬莱市葡萄园土壤酸化及改良技术

Soil Acidification and Improvement Technology in Vineyard of Penglai City

文章调查了蓬莱市葡萄园土壤酸化程度及近几年的变化趋势,并做了葡萄园酸化土壤改良技术试验,提出了施肥对策与建议。调查与试验结果表明:蓬莱市葡萄园酸化情况严重,并呈逐年严重趋势;土壤酸化改良后能不同程度地减少生理病害的发生,病果率降低,平均穗重、可溶性固形物和含糖量增加;施用碱性有机肥的效果比施用生石灰的效果要好,施用碱性有机肥的处理病果率减少幅度大,果穗重增加的多,可溶性固形物增加幅度大,含糖量增加幅度也要高。图1,表4,参12。

In this paper,the scenario and changes concerning vineyard soil acidification in Penglai City were investigated,and a relevant experiment on soil improvement was carried out as well; thereafter,a corresponding countermeasure was suggested. The results showed that vineyard soil acidification in Penglai City is severe and is getting worse yearly. Soil improvement reduced the occurence of vineyard diseases to some extent,decreased the rate of diseased fruit and increased average fruit weight,fruit soluble solids and fruit sugar content. Better effect was found in alkaline organic fertilizer treatment than that of lime treatment,with a lower rate of diseased fruit and increase in average fruit weight,fruit soluble solids and fruit sugar content.
