摘要
分析了红塔区烤烟种植区土壤元素含量,利用经验贝叶斯克里金插值分析了红塔区全境和规划种植烤烟土壤的元素分布情况.结果表明红塔区烤烟种植区域土壤主要问题是pH偏低以及交换性Mg不足区域较大,占比均达50%左右,且缺Mg和pH偏低的区域具有高度的叠加,主要位于红塔区西部和西北部,这 2 个指标具有强烈的正相关性.其次是部分区域有机质、水溶性氯和有效硼含量不足.除元素含量不足的问题外,营养过剩也是需要注意的问题,有效氮和有机质超过适宜含量的面积占比较大,需要控制氮肥和有机肥的施用,这样可以减少农业面源污染,同时节约肥料投入.研究结果可为红塔区烤烟种植区域规划和土壤施肥提供参考.
Abstract
In this study,the soil element content in the tobacco planting area in Hongta District was analyzed,and the element distribution of the soil for the planned tobacco planting in Hongta District using Empirical Bayesian Kriging(EBK)interpolation was analyzed.The results showed that the main problems of the soil in the tobacco planting area in Hongta District were the low pH and the large area of exchange Mg deficiency,accounting for about 50%,and the areas with Mg deficiency and low pH had a high degree of superposition,mainly located in the west and northwest of Hongta District.These two indicators had a strong positive correlation.Secondly,the lack of organic matter,water-solu-ble chlorine and effective boron content in some areas.In addition to the problem of insufficient element content,excess nutrition was also a problem that needed to be paid attention to.The area of nitrogen and organic matter exceeding the appropriate content occupied a large propor-tion,so the application of nitrogen fertilizer and organic fertilizer needed to be controlled,which could reduce agricultural non-point source pollution and saved fertilizer input.The results of this study can provide a reference for regional planning of tobacco cultivation and soil fertili-zation in Hongta District.
