沼液对荔枝果园土壤肥效及果实产量与品质的影响

通过对荔枝果园沼液灌溉与常规化肥不同配比的施肥处理进行试验,研究沼液灌溉对荔枝果园土壤肥效及果实产量和品质的影响.结果表明,沼液灌溉能够显著提高土壤pH值（0.37～0.77）和有机质含量（0.30～2.88g/kg）,改善土壤理化性质,促进土壤碱解氮、有效磷和速效钾等养分含量不同程度的增加,提高土壤肥力;施用了沼肥的处理,其果实的单果重、可溶性固形物、总糖明显增加,可滴定酸显著降低,荔枝果实品质得到显著改善;沼液与化肥的合理混合施用对土壤肥力的提高、荔枝产量的增加及果实品质的改良效果更佳....

Effects of different ratioes of biogas slurry and chemical fertilizer on soil fertility, fruit yield and quality in litchi orchard were studied. The results showed that biogas slurry irrigation c, ould increase the pH value of siol and organic matter content in soil by 0.37-0.77 and 0.30-2.88 g/kg respectively,and could increase the soil alkaline hydrolytic N, available P and available K content in different degree. Compared with treatments of ehemical fertilizer and no fertilizer, soil physical and chemical properties and soil fertility were significantly improved. After applied with biogas slurry, total soluble solid and total sugar of litchi fruits increased evidently, titratable acid
