腐植酸复合肥对葡萄品质及产量的影响

针对长期大量施用化肥使果园土壤养分失衡、果品质量下降等问题，研究了新型腐植酸复合肥用以大田葡萄的应用效果。结果表明：所有施肥处理比对照有显著的增产效果。在投入养分量相等条件下，腐植酸能显著提高葡萄产量、果实单粒重和VC的含量，增加了果实中还原糖和可溶性固形物的含量，部分降低果实中有机酸的含量。

The effect of humic acid (HA) compound fertilizer on the quality and production of grape

The fertilizer used in the vineyard for a long time will cause a lot of problems like the disequilibrium of soil nutrients, the deterioration of fruit quality, etc, so a new HA compound fertilizer was applied to grape (Kyoho) in the field experiment. The results showed that all fertilizer treatments were notably out-weighted the CK. With equal-nutritional quantity, HA compound fertilizer apparently increased the production of grape, the weight of single grape berry and the content of Vc, and it also effectively enhanced the reductive sugar and total soluble solids of fruit, decreased the titratable acidity partly.
