不同有机肥施用量对葡萄产量、品质及土壤养分的影响

Effects of Different Organic Fertilizer Application Levels on the Yield and Quality of Grape and Soil Nutrition

以7年生葡萄树为供试材料,研究了不同有机肥施用量对葡萄产量、品质及土壤养分的影响。结果表明,有机肥的施用,有效地提高了葡萄产量、品质及土壤有机质含量。当有机肥施肥量为60t/hm^2,葡萄增产12.8%,可溶性固形物、糖酸比、Vc分别增加9.0%、15.7%和11.7%,土壤有机质含量提高22.7%。

Seven-year-old grapes were used to study the effects of different organic fertilizer application rates on grape yield, quality and soil nutrients.The results showed that the application of organic manure effectively increased the content of soil organic matter, grape yield and quality.When the amount of organic manure was 60t/hm^2 , the content of soil organic matter increased by 22.7%, grape yield increased by 1975.5kg/hm^2 , by 12.8%;soluble solids, sugar-acid ratio and Vc increased by 9.0%, 15.7% and 11.7% respectively.
