| 摘 要： | 为探讨果园土壤矿质元素与叶片营养水平的相互关系,于巴仁杏盛果期采集南疆阿克陶县巴仁杏果园的壤土和沙土土样,以及植株叶片,测定土壤与叶片矿质元素质量分数,结果表明,该地区2种类型土壤巴仁杏果园叶片全氮质量分数均偏低,沙土果园叶片镁质量分数偏低。不同土壤类型果园叶片全氮、钾、钙、镁质量分数差异显著。该地区果园土壤养分整体较低,其中,土壤有机质、氮、磷、锌、锰、铜质量分数均偏低,此外不同矿质元素在不同土层的分布规律因土壤类型不同而各有差异。2种土壤类型果园的土壤有机质质量分数与叶片磷质量分数均呈正相关,叶片其他矿质元素质量分数与土壤有机质质量分数的相关性与土壤类型有关;土壤矿质元素与叶片相应矿物质元素的相关性因土壤质地不同而存在较大差异。因此,在巴仁杏果园的土肥管理中应增施有机质及氮、磷、锌、锰、铜、硼等矿质元素。此外,对不同土壤类型果园的管理应根据果园土壤类型进行针对性施肥。

| Abstract: | In order to study the correlation relationship between soil nutrient elements and leaf nutrition mass fraction in Baren apricot orchards nutrient elements in soil and leaf were analyzed in full fruit period orchards with loam and sandy soil respectively in South Xinjiang Akto County. The result showed that the leaf nitrogen mass fraction was low in both soil texture orchards, and the leaf magnesium mass fraction was low in sand soil orchard. The leaf total nitrogen, potassium, calcium and magnesium mass fraction have significant difference among loam and sandy soil texture orchards. The orchard soil nutrition elements (organic matter, N, P, Zn, Cu) mass fractions in Akto County are all in lower range. The fertilizer elements mass fraction distribution characteristic in surface and deep layer is difference between different kinds of soil texture orchards. There was a positive correlation between soil organic matter mass fraction and leaf phosphorus mass fraction in both texture orchards. The relationship between soil organic mass fraction and leaf nutrition elements mass fraction was different in various soil texture orchards. The relationship between soil mineral elements and the corresponding leaf mineral elements changed with soil texture. The Baren apricot orchard fertilizer management should pay attention on increasing organic matter, N, P, Zn, Mn, Cu and B, and should use different fertilization measures for different soil textures. |
