摘  要:
【目的】通过对新疆轮台县9个乡镇轮台白杏叶样的采集与分析,旨在了解轮台白杏树体营养盈亏状况,以期为轮台白杏的优质丰产提供施肥需求的科学依据。【方法】采用化学分析方法测定轮台白杏叶样常量元素N、P、K、Ca、Mg和微量元素Fe、Mn、Cu、Zn浓度,并运用诊断与施肥建议综合法(DRIS)分析轮台白杏树体营养盈亏状况。【结果】轮台白杏DRIS诊断指标为叶片Zn、Ca浓度和N/P、N/Fe、N/Mn、N/Cu、N/Ca、N/Mg、P/Fe、P/Mn、P/Cu、P/Ca、P/Mg、K/N、K/P、K/Zn、Fe/K、Fe/Mn、Mn/K、Mn/Cu、Mn/Ca、Mn/Mg、Cu/K、Cu/Fe、Cu/Ca、Cu/Mg、Zn/N、Zn/P、Zn/Fe、Zn/Mn、Zn/Cu、Zn/Ca、Zn/Mg、Ca/Fe、Mg/K、Mg/Fe、Mg/Ca浓度比值;轮台白杏树体养分浓度平衡值为N:1.68 g/kg、P:0.54 g/kg、K:2.36 g/kg、Ca:7.43 g/kg、Mg:0.23 g/kg、Fe:246.23 mg/kg、Mn:25.03 mg/kg、Cu:0.95 mg/kg、Zn:26.43 mg/kg。【结论】新疆轮台县轮台白杏树体K、P、Cu、Ca、Fe以缺乏为主,Mn、Zn、Mg、N以供应充足为主,科学、合理施肥是轮台白杏优质丰产的必要条件。

摘  要:
【Objective】Based on the collection and analysis on leaf samples of Armeniaca vulgaris 'Luntaibaixing' in the nine townships,Luntai County,to understand its nutrients of abundance and loss situation,to provide the scientific basis in needing fertilization for its fruits of good quality and high yield.【Method】The leaf samples of constant elements of A.vulgaris 'Luntaibaixing' including N,P,K,Ca and Mg and the concentration of microelements including Fe,Mn,Cu,Zn were analyzed with chemical methods,and using the diagnosis and recommendation integrated system(DRIS),the nutrients of abundance and loss situation of A.vulgaris 'Luntaibaixing' were analyzed.【Result】The DRIS diagnostic indices were Zn,Ca concentration and N/P, N/Fe,N/Mn,N/Cu,N/Ca,N/Mg,P/Fe,P/Mn,P/Cu,P/Ca,P/Mg,K/N,K/P,K/Zn,Fe/K,Fe/Mn,Mn/K,Mn/Cu,Mn/Ca,Mn/Mg,Cu/K,Cu/Fe,Cu/Ca,Cu/Mg,Zn/N,Zn/P,Zn/Fe,Zn/Mn,Zn/Cu,Zn/Ca,Zn/Mg,Ca/Fe,Mg/K,Mg/Fe,Mg/Ca concentration ratio of the leaves.The quantitative value of nutrient concentration equilibrium was N: 1.68 g/kg,P: 0.54 g/kg,K:2.36 g/kg,Ca:7.43 g/kg,Mg: 0.23 g/kg,Fe:246.23 mg/kg,Mn: 25.03 mg/kg,Cu: 0.95 mg/kg,Zn: 26.43 mg/kg.【Conclusion】The K,P,Cu,Ca,Fe were in short supply,and the Zn,Mg,Mn,N were with sample supply mainly in A.vulgaris 'Luntaibaixing'.The scientific and rational fertilization was necessary for the fruits of good quality and high yield of A.vulgaris 'Luntaibaixing' in Luntai County.
