摘要
为评估咸阳市耕地养分含量水平,给相关研究及农业生产提供参考。通过测量南部平原区、中部台塬区、北部沟壑区三个代表性区域耕地土壤的有机质及大量元素含量,研究咸阳市的耕地营养状况。结果表明:咸阳市耕地养分在不同地区、不同耕地类型间差异较大,南部平原区高于中部台塬区及北部沟壑区;耕地普遍缺乏碱解氮及有机质、钾肥,果园缺肥严重、最缺钾肥,撂荒地养分恢复明显。咸阳市耕地养分状况将为农业生产及产业结构调整提供有价值的参考。
In order to evaluate the nutrient content level of cultivated land in Xianyang comprehen- sively, and to provide reference for related research and agricultural production, the organic matter and main elements of cultivated land in the southern plain area, middle tableland area and northern gully re- gion of Xianyang were evaluated. The results show that the fertility level of cultivated land varies great- ly among different regions and different cultivated land types. The comprehensive fertility level in the southern plain is higher than that in the middle tableland and the northern gully region. Alkali hydrolyz- able nitrogen, organic matter and potassium were deficiency in common in cultivated land. Orchards＇ lack of nutrients is very serious especially in terms of lack of potassimu. Fallow land fertility restora- tion is very obvious. The nutrient status of cultivated land in Xianyang will provide valuable references for agricultural production and industrial structure adjustment.
