Study on the Nutrient Abundance and Deficiency of Soil Elements in the Tobacco Planting Area of Hongta District,Yuxi City
摘要
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.关键词
