【摘要】 【目的】探讨草炭对果园土壤理化性状及桃果实品质的影响。【方法】以4年生桃艳丰一号为试材,应用土壤局部改良法,研究了草炭与鸡粪配合(C1P0:鸡粪50 kg/株;C2P0:鸡粪100 kg/株;C1P1:鸡粪50 kg/株+草炭10 kg/株;C2P1:鸡粪100 kg/株+草炭10 kg/株;C1P2:鸡粪50 kg/株+草炭20 kg/株;CK:自制农家肥)施用对桃园土壤理化性状、桃树根系分布和桃果实品质的影响。【结果】鸡粪和草炭配合施用能显著降低桃园20~40 cm土层土壤容重、增大孔隙度,各处理影响顺序为C1P2>C2P1>C1P1>C2P0>C1P0;处理C1P2的土壤有效P、Fe、Zn、B含量分别比对照增加132.58%,77.62%,195.97%和152.33%。鸡粪与草炭配施能显著增加20~40 cm土层内根系总量,其中以C1P2处理根系总生物量最大,比对照增加240.14%。处理C1P2的果实品质最好,固酸比比对照提高33.08%。【结论】鸡粪50 kg/株+草炭20 kg/株是改良桃园土壤、增加桃树根系数量、提高桃果实品质的最佳配肥组合。更多还原

【Abstract】 【Objective】 The study is to improve orchard’s soil fertility and fruit quality.【Method】 The method of localizing soil amendment was utilized to study the effect of peat and chicken manure combination(C1P0:chicken manure 50 kg;C2P0:chicken manure 100 kg;C1P1:chicken manure 50 kg+peat 10 kg;C2P1:chicken manure 100 kg+peat 10 kg;C1P2:chicken manure 50 kg+peat 20 kg;CK:farm manure 50 kg.) on soil property,root distribution and fruit quality of Yanfeng NO.1 peach tree.【Result】 The results showed that bulk density and porosity in 20-40 cm soil layers were significantly reduced and increased by applying combination of chicken manure and peat,and the influence sequence of different treatments were C1P2>C2P1>C1P1>C2P0>C1P0.The available P,Fe,Zn,B were enhanced 132.58%,77.62%,195.97%,152.33% in C1P2 than CK separately.The root biomass in 20-40 cm soil layers was significantly increased,and the total root biomass in C1P2 was increased 240.14% than CK.The fruit quality of C1P2 was the best,and TSS/TS was improved 33.08% than CK.【Conclusion】 The best treatment is an optimum scheme of combination chicken manure 50 kg with peat 20 kg for amending soil to increase roots quantity and improve fruit qualities of peach.更多还原
