Analysis on Nutrients of Abundance and Loss Situation of Armeniaca vulgaris 'Luntaibaixing' in Luntai County, Xinjiang
摘要
Abstract
[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.关键词
