| Armeniaca vulgaris ’luntaibaixing’ is the superior breed (new S-SV-PA-017-2009) in the origin territory of luntai, Xinjiang province. As it has been allowed to the geographical indication protection, it is the main opening apricot cultivar with more than1,000years of cultivation history. Under the conditions of general production management, field sampling and analysis of laboratory experiments has been used. I also do some research on nutrient concentrations, soil nutrient content and the relationship between them. Meanwhile, the soil fertility, tree body nutrition profits and losses in the Armeniaca vulgaris ’luntaibaixing’ production garden have been discussed. The main results are as follows:The soil nutrient status in Armeniaca vulgaris ’luntaibaixing’ production garden is that organic matter, effective Mn, effective Cu content is moderate, while available K and available Fe content is higher. And total N and available P content are low, which can meet the needs of tree. At the same time, it shows that Armeniaca vulgaris ’luntaibaixing’ grows well with abundant of Fe and Ca. What’s more, antagonistic and synergistic effects between the leaf nutrient elements are quite common. The relationship in leaf nutrient elements is positively correlated. Among soil nutrients, which associated with organic matter at most are really relevant.The soil nutrient elements of the blade nutrition elements of influence is a complex chemical process, leaf is the accumulation of nutrient elements in soil nutrient element is more than the result of joint action, leaf different nutritional element from the soil nutrient element influence of different, and more soil nutrient element and copper a leaf nutrition elements of a relationship is a negative, the content of nutrient elements by soil nutrient content in outside influence, leaf itself can also affect the size of the content.There are some factors influencing the soil fertility in the Armeniaca vulgaris ’luntaibaixing’ production garden, such as organic matter, available N, available P, available K, total N, available Fe, effective Mn, effective Cu, and available Zn. Every garden soil fertility comprehensive evaluation index is between0.21-0.89, with an average value of0.49, which is a lower-middle level. In different soil fertility levels, leaf nutrition elements and the soil nutrient contents there are certain differences.The Armeniaca vulgaris ’luntaibaixing’DRIS diagnostic indicators is made up of30diagnostic indicators, consisting of four single-element concentration indicators and26leaf nutrient element concentration ratio index. The four single-element concentration indicators are N, P, Ca, Mg, and the26leaf nutrient element concentration ratio index are N/P, N/K, P/Fe, P/Mn, P/Cu, P/Ca, K/Cu, K/Ca, Fe/N, Fe/K, Fe/Ca, Mn/N, Mn/Zn, Cu/Zn, Zn/N, Ca/N, Ca/Mn, Ca/Cu, Ca/Zn, Mg/N, a total of30Mg/P, Mg/Fe and Mg/Mn and Mg/Cu and Mg/Zn, Mg/Ca and so forth.The Armeniaca vulgaris ’luntaibaixing’ garden is mainly in lack of N, P, K, Zn, while Fe, Mn, Cu, Ca and Mg are mainly to an adequate supply. The preliminary study said that the appropriate range of nutrient concentrations of Armeniaca vulgaris ’luntaibaixing’ is N for (0.17-2.76) g/kg, P for (0.10-0.73) g/kg, K for (2.76-5.46) g/kg, Ca for (6.42-7.38) g/kg, Mg for (0.19-0.27) g/kg, Fe for (172.15-262.01) mg/kg, Mn for (19.05-35.93) mg/kg, Cu for (0.99-1.24) mg/kg, Zn for (10.13-25.32) mg/kg. |
