摘要: 【目的】研究新疆叶城县果园土壤大量元素养分含量及分级,合理培肥。【方法】基于叶城县果园 782 份土壤样本数据:水解性氮、有效磷、速效钾、全氮、有机质5个养分指标,分析土壤养分变异系数,依据土壤分级标准和土壤现状进行土壤养分分级。【结果】叶城县果园土壤大量养分变异系数在20.86%~69.08%,各养分均属于中等变异性;土壤有机质、全氮、速效钾含量处于低水平,有效磷含量处于中低水平,水解性氮含量处于中等偏高水平。【结论】叶城县果园土壤大量元素养分水平总体偏低。应重视有机肥的使用,以培肥地力;保证氮磷钾肥充足合理的施用,特别要重视磷、钾肥的施用,以保证当季作物的优质高产需要。

Abstract: 【Objective】 This paper aims to study the nutrient content and classification of abundant elements in orchard soil in Yecheng County, Xinjiang and put forward reasonable fertilization suggestions.【Method】Based on 782 soil samples data in Yecheng County orchard: five nutrient indexes, including hydrolysis nitrogen, effective phosphorus, rapidly-available potassium, total nitrogen and organic matter, the variation coefficient of soil nutrient was analyzed, and according to soil classification standard and soil status, the soil nutrients were classified.【Result】The nutrient variation coefficient of soil in Yecheng County orchards was within the range of 20.86% and 69.08%, and all nutrients were of medium variability. Soil organic matter, total nitrogen and rapidly-available potassium content were low, while effective phosphorus content was at medium or low levels, and content of hydrolyzed nitrogen was at medium high level.【Conclusion】The nutrient level of a large amount of elements in orchard soil of Yecheng County is generally low, so it is suggested that use of organic fertilizer should be taken seriously. At the same time, it is necessary to ensure sufficient and reasonable application of NPK fertilizer, especially application of phosphorus and potassium fertilizer to guarantee high quality and yield of crops in the season.
