g/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。 |
| 英文摘要: |
| 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 could 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袁and could increase the soil alkaline hydrolytic N, available
P and available K content in different degree. Compared with treatments of chemical 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 content significantly reduced袁and litchi quality were obviously
improved. The reasonable mixture of biogas fertilizer and chemical fertilizer was more effective to improve soil fertility, fruit
yield and quality in litchi orchard. |
