摘　　要：以‘丰水’梨为试材,研究分析梨园"草-鹅-果"种养结合模式和传统栽培模式下土壤的有机质含量、土壤脱氢酶、脲酶、蔗糖酶、过氧化氢酶活性以及果实品质的差异。结果表明:种养结合模式能提高梨果实单果重,增加梨园土壤有机质含量,改变土壤脱氢酶、脲酶、蔗糖酶、过氧化氢酶活性,在各个采样时期的土壤酶活性各有不同。种养结合梨园果实单果重比清耕梨园增加9.8%,果实可溶性固形物和可溶性糖分别增加4.1%和14.7%,果实可溶性酸和硬度分别下降7.1%和3.7%。Fruits of ＇Hosui＇were used as materials for studying the difference of soil organic matter,soil dehydrogenase activity,soil urease activity,soil sucrase activity,soil catalase activity and fruit quality compared with the soil clean orchard in the ＇ weeds-goose-fruit ＇ crop-animal mixed orchard.Results showed that the fruit output and the content of the soil organic matter increased in the type of crop-animal mixed orchard,the activity of the soil dehydrogenase,soil urease,soil sucrase and soil catalasel were altered,and the enzyme activity varying different in each period.The single fruit weight of the crop-animal mixed orchard increased by 9.8% than the soil clean management orchard.The total soluble solid and the sugar content increased by 4.1% and 15.9% respectively,the soluble acids and the firmness should be declined by 7.1% and 3.7% singly.
