| 摘要: |
| 在‘丰水梨’有机果园分别施用仲元、 赛众28、中合和BGA牌商品有机肥，检测树体生长发育、果实营养品质及土壤理化性状等指标，结果表明：除果实可滴定酸含量外，仲元牌有机肥在新梢生长量、叶片光合色素含量、单果重、果实硬度、果实可溶性固形物含量、果实SOD活性、果实总类黄酮含量及土壤全氮和速效钾含量、有机质含量、土壤菌落总数等指标上明显高于其他商品有机肥和自制堆肥；赛众28和中合牌有机肥在比叶重、果实SOD活性和土壤菌落总数等指标上显著高于对照；BGA牌有机肥显著提高了叶片叶绿素a+b含量和果实总类黄酮含量。总体上4种商品有机肥的效果不同程度上优于对照。施用效果：仲元牌有机肥>赛众28、中合和BGA牌有机肥>自制堆肥。 |

| Abstract: |
| Four commercial fertilizers of Zhongyuan, Saizhong 28, Zhonghe and BGA were applied in‘Housui Pear’.The measured parameters were growth index, development of trees, fruit nutritional quality, soil physical and chemical properties.The results showed that the plant used ‘Zhongyuan’ organic fertilizer had higher values of shoot length, pigment content in leaves, single fruit weight, fruit firmness, TSS, SOD activity, fruit flavonoid and soil total N, available K, organic matter and microorganism, but low TA in fruits, compared to other commercial organic fertilizers and homemade compost.The plant added with organic fertilizer‘Saizhong 28’and‘Zhonghe’were higher in the index of specific leaf weight, fruit SOD activity and soil microorganism than CK.The‘BGA’organic fertilizer significantly increased the concentrations of Chl.a and Chlb in leaves and fruit flavonoid.The effects of four commercial organic fertilizers on plant are in the order of ‘Zhongyuan’organic fertilizer > ‘Saizhong 28’, ‘Zhonghe’ =‘BGA’Commercial organic fertilizers>homemade compost. |
